The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
The Model 120 was originally created in 1982 as a custom built siren for the SONGS plant, which had strict requirements for its siren system. SONGS had gone through two other systems before this point, with a system of 39 [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and tested January 25th thru 27th, 1982. The Sentry sirens were found to perform terribly compared to what was advertised, leading to the sirens being removed an replaced. SONGS would then install a new system of 39 [[Federal Signal]] [[STL-10]]'s with those being installed by April of 1982 and tested in May of the same year. While the STL-10's performed significantly better than the Sentry sirens did, they still didn't meet the plant's needs. The only sirens on the market with enough range that would meet the plant's needs at the time were rotational sirens, but SONGS wanted to use exclusively omnidirectional sirens. So, they decided to design and create their own siren to meet their requirements.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in Summer 1982.]]<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in October 1982. Originally, the plan was after the first Model 120's were installed, a total of 52 additional Model 120's were going to replace the existing [[Federal Signal]] [[STL-10]]'s and making the system entirely Model 120's. This plan was dropped shortly afterwards due to the increasing delays and costs caused to the plant by not having a ready siren system by 1981 which was the original year planned for the plant's 2 newly constructed reactors to begin operating. Units #2 and #3 were ready to begin operation, but because the siren system was inadequate they couldn't begin operation until the Model 120's were installed. This caused a delay for over a year, as it also happened around the same time the NRC required nuclear plants to have siren systems. This also meant the plant's existing Unit #1 could not be restarted until the siren system was ready.<br />
<br />
There were 22 of these sirens produced, with one being never installed and put into storage as a spare. 16 of these were installed in October 1982 to add into the system of STL-10's, 8 of which indirectly swapped out with Model 120's with another 8 being brand new installs. 5 additional sirens were installed in 1988, one of which replaced a [[Federal Signal]] [[Thunderbolt]] that was an existing Civil Defense siren.<br />
<br />
After the Model 120's went up, in order to end the delays of the siren system not being up to par, SONGS opted to just keep the remaining [[Federal Signal]] [[STL-10]]'s and add 21 Model 120's in areas that need coverage and to swap out specific STL-10 sites that had the worst range compared to the others, (First 8 sites), to get the EPZ up to code for the plant's reactors to start. After a successful system test on May 4th, 1983, the plant's new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 being restarted. These delays, and the cost of the sirens themselves cost the plant over $1 million dollars.<br />

<br />
For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba which made pneumatic sirens. The Model 120 is a Supercharged Electromechanical siren, but also more or less acts like a pneumatic siren due to the rotor lacking any vanes, meaning it requires an external air source to produce any meaningful sound, such as the [[Thunderbolt]] and [[Hurricane]]. The sound is created by a 4-port (later 5-port) single tone rotor, which spins inside the stator, which acts as a chamber to contain the air inside. The rotor is driven by a 2 Hp TEFC motor that runs at 3450 RPM. The siren has an 8-port stator with narrow ports, and the sound is then projected by 8 large fiberglass horns attached to the stator. The siren makes use of a belt driven Paxton centrifugal blower, that uses a 10 Hp TEFC motor which sits below the siren's head to force pressurized air up into the rotor. The 4-port units reached a frequency of 240 Hz (480 Hz without the blower) and the 5-port units reached 300 Hz. The rotor and stator are both coated in Teflon, which helps seal the air in and prevent leaks, while also helping to protect them from corrosion from the salty air. The rotor is 9.75 inches in diameter and including the stator, which it alone is over 2 inches in diameter, is in total 11.75 inches in diameter.<br />
<br />
<br />
<br />
By June of 2004, the plant began discussing a system replacement project due to the sirens suffering from advanced corrosion and degrading reliability due to the system's proximity to the ocean, along with the system "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120's and the STL-10's started to be gradually removed and replaced, and by February 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. [[Whelen Engineering]] [[WPS-2800 series|WPS-2810]]'s and [[WPS-2800 series|WPS-2806]]'s were installed in their places. The 2810's went in place of the Model 120's and the 2806's went in place of the STL-10's. <br />
<br />
These new electronic sirens have battery backup, are less maintenance due to their resistance to corrosion and no moving parts, and have similar ranges to the original system such as the 2806's having better range compared to the STL-10's, and the 2810's having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ. These new sirens met the strict requirements of the plant without the need to specifically design a new siren as by the 2000's, there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10's.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10's to Curry County, Oregon to be used as tsunami sirens, 8 of which were installed, and the Model 120's and remaining 5 STL-10's are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in private possession currently under restoration to be brought back into operating condition.<br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' Community Alert Siren System was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />
<br />
Unlike most run of the mill Whelen systems that are mostly always activated by via radio, San Onofre's system was hardwired, and activated by via landline DTMF. This applied to both the legacy and latest systems. It is unknown why the system even from the start was not just radio activated, but it could be because either for security reasons, or the lack of repeater towers nearby or close to the area all the sirens are in, and there was already landline infrastructure in place before the original system was even installed.<br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
The Model 120 was originally created in 1982 as a custom built siren for the SONGS plant, which had strict requirements for its siren system. SONGS had gone through two other systems before this point, with a system of 39 [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and tested January 25th thru 27th, 1982. The Sentry sirens were found to perform terribly compared to what was advertised, leading to the sirens being removed an replaced. SONGS would then install a new system of 39 [[Federal Signal]] [[STL-10]]'s with those being installed by April of 1982 and tested in May of the same year. While the STL-10's performed significantly better than the Sentry sirens did, they still didn't meet the plant's needs. The only sirens on the market with enough range that would meet the plant's needs at the time were rotational sirens, but SONGS wanted to use exclusively omnidirectional sirens. So, they decided to design and create their own siren to meet their requirements.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in Summer 1982.]]<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in October 1982. Originally, the plan was after the first Model 120's were installed, a total of 52 additional Model 120's were going to replace the existing [[Federal Signal]] [[STL-10]]'s and making the system entirely Model 120's. This plan was dropped shortly afterwards due to the increasing delays and costs caused to the plant by not having a ready siren system by 1981 which was the original year planned for the plant's 2 newly constructed reactors to begin operating. Units #2 and #3 were ready to begin operation, but because the siren system was inadequate they couldn't begin operation until the Model 120's were installed. This caused a delay for over a year, as it also happened around the same time the NRC required nuclear plants to have siren systems. This also meant the plant's existing Unit #1 could not be restarted until the siren system was ready.<br />
<br />
There were 22 of these sirens produced, with one being never installed and put into storage as a spare. 16 of these were installed in October 1982 to add into the system of STL-10's, 8 of which indirectly swapped out with Model 120's with another 8 being brand new installs. 5 additional sirens were installed in 1988, one of which replaced a [[Federal Signal]] [[Thunderbolt]] that was an existing Civil Defense siren.<br />
<br />
After the Model 120's went up, in order to end the delays of the siren system not being up to par, SONGS opted to just keep the remaining [[Federal Signal]] [[STL-10]]'s and add 21 Model 120's in areas that need coverage and to swap out specific STL-10 sites that had the worst range compared to the others, (First 8 sites), to get the EPZ up to code for the plant's reactors to start. After a successful system test on May 4th, 1983, the plant's new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 being restarted. These delays, and the cost of the sirens themselves cost the plant over $1 million dollars.<br />

H.O.R (Commonly misconcepted as Hear Our Roar. It actually stands for Harry O. Ricci, the name of the founder of the company) was a siren company based in Staten Island, New York, that built the Super Sirex and Siro-drone sirens. There are very few active units in the United States.<br />
The Super Sirex came in either 15, 40, or 50 horsepower. They either had port ratios of 9/9, 10/10, and 7/10. They were available in both dual and single head models, with or without a rotator. <br />
The Siro-Drone came in 1/8, 2, 3, 5, and 7 1/2 horsepower and were smaller vertical sirens similar to a Fedelcode/Federal siren. Its port ratios were 9,10, and 12 port. Over 700 HOR Siro-Drones and 34 Super Sirexes were installed in New York City, as part of the city's civil defense program. HOR also had another vertical siren, similar to the Super Sirex, called the Sirex, of which there are three known to be active in Massapequa, New York.<br />
<br />
In the mid 60s, HOR moved their headquarters to Phoenix, Arizona, where they installed a large amount of Super Sirexes, to aid the existing system of Federal Signal Thunderbolt 2000 sirens. At least three of these Super Sirexes still exist to this day, two in private possession, and one reinstalled in Adrian, Missouri. Phoenix also had at least one dual tone HOR Sirex, which is currently in private possession.<br />

<br />
W.S. Darley & Co. is a company that has been selling a wide variety of products since 1908, including fire apparatus equipment, traffic signals, robotics and defense equipment, as well as civil defense and fire sirens. While they no longer produce their own sirens, they currently sell rebranded Sentry products.<br />
<br />
<br />
== Darley Champions ==<br />
Darley entered the siren business as early as 1932, when the demand for fire sirens was still quite high. Their first line of sirens was the Champions, a series of small omnidirectional sirens. These ranged from single and dual rotor horizontal sirens, as well as several vertical sirens. These came in many shapes and sizes. These were in production until the late 1930s. <br />
<br />
=== Peerless Champion ===<br />
The Peerless Champion was a dual headed siren, similar those used in Britain during WWII. They were meant for use as fire sirens, and their biggest competitor was the [[Sterling]] Model M. These sirens were dual rotor single tone, and were never produced in dual tone. These used a dual sided 5HP AC motor, driving two rotors, and were available in 8-port single tone. The motor sat on a large base stating "CHAMPION, W.S. DARLEY & CO, CHICAGO". These had thinner rotors than the Super Champion, with 4 long vanes and 4 short vanes. The intakes were styled with a flare on the stator, and the stator ports were protected by a mesh screen. The Peerless Champion did not last long in production, and none of these are known to still exist. <br />
<br />
=== Super Champion ===<br />
The Super Champion is very similar to the Peerless Champion, but overall larger in size. The Super Champion uses longer rotors for better sound output, and is driven by a 7.5HP dual sided AC motor. These Champions were much more successful than the Peerless Champion, due to their better performance. These came in both 8-port and 16-port single tone, with no dual tone options offered. Interestingly, the 16-port units use 16-port rotors inside of an 8-port stator, leading to significant undertones. Like the Peerless Champion, the rotors use 4 long vanes along with 4 or 12 short vanes depending on the port count. Both single and dual headed models are known to exist. The overall design of the Super Champion is largely identical otherwise to the Peerless Champion, and several units can still be found as noon blast sirens or fire sirens. <br />
<br />
=== Vertical Champion ===<br />
These are single headed, vertical Champions. Also commonly referred to (and misnamed) as the ''Darley 3V8'', these are essentially a single headed Champion flipped on its side vertically, using the same rotor, stator and intake. The siren was available in either 2.5HP (using the rotor and stator from the Peerless Champion, named the "Champion Giant") or 5HP (using the rotor and stator from the Super Champion, named the "Champion Fire Siren"). The 2.5HP variant was exclusively 8-port single tone, while the 5HP variant was available in either 8-port or 12-port single tone. The intake on these sirens are protected by a large two-piece intake cover attached to the stator, which keeps debris and rain out of the rotor, and is often equipped with a mesh screen around the intake and stator ports. The motor itself is held up by three mounting legs, which attach to wherever the siren is mounted. 2.5HP Vertical Champions have intake covers that extend halfway down the stator, while 5HP ones have covers that don't extend past the width of the stator. These were some of the cheapest sirens available in the 1930s, which made them quite popular at the time, and some have even found their way as far as Quebec, Canada. <br />
<br />
=== Weatherproof Champions ===<br />
These are also vertical sirens, but they differ quite significantly to the standard Vertical Champions. These sirens were designed with durability and longevity in mind, rather than price. Unlike the Vertical Champions, the Weatherproof Champions use a motor-over-rotor configuration, with the motor on top and the rotor and stator being located below, held up by a few supports. These sirens were placed inside weatherproof housings with a rounded top, and many slits are placed across the diameter of the housing to allow sound to escape, similar to a Sparton Sirens Sparton. While this does a much better job of protecting the siren itself from the elements, it does harm the siren's ability to project, and they tend to be quieter than other Champion models.<br />
<br />
These came in three different varieties. The 2.5HP version came exclusively in 6-port single tone, using a universal motor. These were very similar to the [[Federal Signal]] [[Model 2]], and had overall shorter housings than the other Weatherproof Champions, with only a single row of slits. The 5HP version uses a standard 5HP AC motor, and was available in either 8-port or 12-port single tone. The 12-port rotors on these use 6 long vanes and 6 short vanes, which gives it a significant rasp, similar to the [[Sterling]] 5VX. These are taller than the 2.5HP model, and can have either one or two rows of slits. The 7.5HP version is very similar to the 5HP model, but comes exclusively in 12-port single tone, with a rotor that has all long vanes and no short vanes. These can also have one or two rows of slits on the housing.<br />
<br />
=== Champion Little Giant ===<br />
These are the smallest model that was available, and was Darley's take on Sterling's [[Sterling]] Little Giant siren. Running on a 1.5HP single phase AC motor, which drove two 10-port rotors at 4400RPM, this siren was meant for short range use by small rural volunteer fire departments, or industrial work lunch whistles. The rotors and stators are enclosed inside small stylized horns, resembling the shape of the stators used in the larger Champion models, and the stators lack a ring on the edge of the stator ports. The siren also comes with the W.S. Darley branded stand, which is removable. These are rare to find compared to other Champion units. <br />
<br />
== Federal Rebrands ==<br />
In the 1940s, W.S. Darley & Co. discontinued their original Champion line of sirens, instead partnering with Federal Signal (then Federal Electric) to produce rebranded versions of the [[Federal Signal]] Fedelcode (and later [[Federal Signal]] Model X series) line of sirens. These sirens, like all of Darley's sirens, are also known as "Champions" and are identical mechanically to their Federal counterparts, using the exact same rotors, stators, and motors. The only difference between a Federal branded siren and a Darley branded siren is the housings. Darley's housings are much more rounded and ornate, often resembling a fire hydrant. <br />
<br />
Darley made their own variants of the [[Federal Signal]] [[Model A]], [[Federal Signal]] [[Model L]], [[Federal Signal]] [[Model 2]], Model 5 (C2 1/2), Model 7 (C3 1/2) and their dual tone variants, and the [[Federal Signal]] [[STH-10]]. The Darley STH-10 in particular is unique in that it has the motor on the bottom and the intake on the top, with a housing bracket, unlike Federal's version with the motor on top and intake below. This made it very similar to the Model X series of sirens, but used the STH-10's rotor and stator. Another thing to note is that the dual tone variants of the Model 5 and Model 7 are marked on the tag with two "T"s (5TT and 7TT) instead of Federal's normal designation of 5T and 7T. <br />
<br />
These would be produced until sometime in the 1960's, when they were discontinued. However, Darley continues to sell the Federal Signal Q2B to this day, as well as its electronic counterpart. <br />
<br />
== ACA Rebrands ==<br />
In the 1970s, W.S. Darley & Co. partnered with Alerting Communicators of America (ACA) to produce rebranded versions of their sirens. These sirens were physically identical to their ACA counterparts, with the only difference being the addition of "DARLEY" branding on the housings of the sirens. These were sold under the Champion brand and often advertised by their horsepower rating, and many different models were sold including the [[Screamer]], Super [[Banshee]], [[Allertor 125]], and [[Hurricane]]. <br />
<br />
In the 1980s, the Darley catalogue would be expanded, now also selling the standard [[Banshee]] 115 (referred to as the Banshee 10), [[Cyclone]] 125, [[Penetrator series]] P-15 (advertised as the P-10), and Penetrator-50, as well as the [[Alertronic Series]] line of electronic sirens (including the now-extinct Alertronic 5000). The sirens were now referred to by their ACA-given names, though they also kept their Darley-specific model names. The "DARLEY" branding on the housings was also removed by this point, making them indistinguishable from ACA-branded sirens. This partnership would continue through the 1980s, likely ending in the 1990s when ACA faced bankruptcy. It is unknown how many Darley-branded ACA sirens survive to this day, as the brandings on the sirens have likely faded, and later models lacked any branding. One W.S. Darley branded Allertor 125 is known to survive in service, located in Niles, MI.<br />
<br />
== Sentry Rebrands ==<br />
During the 1980's, Darley also chose to partner with the then-new Sentry Siren, selling rebranded versions of their sirens. These rebranded Sentry sirens were sold alongside Darley's rebranded ACA sirens, until ACA went out of business. Originally, only the [[Sentry Siren Incorporated]] [[10V2T]] and F-2 were offered, under the names "Dual Tone General Alert Siren" and "110/220V Alarm Siren". The short lived 3-signal [[Sentry Siren Incorporated]] [[10V2T]]-3S was also offered by Darley.<br />
<br />
After ACA's bankruptcy, Darley continued to partner with Sentry exclusively, becoming one of many companies reselling Sentry's sirens. These sirens are identical to their Sentry counterparts, and are Sentry-branded from the factory. This makes it impossible to tell whether a given siren is from Sentry themselves, or from Darley. At least one siren is confirmed to have been bought from Darley, a [[Sentry 10V|10V]] located in Glenbeulah, WI. Darley expanded their options, and as of today now sells rebrands of the F-2, E-6, [[Sentry Siren Incorporated]] [[3V8]] (and 3V8-H), [[Sentry Siren Incorporated]] [[7V8]], [[Sentry Siren Incorporated]] [[10V]], [[Sentry Siren Incorporated]] [[14V]], 10V2T (despite it being discontinued by Sentry) and the [[Sentry Siren Incorporated]] [[15V2T]] (which Darley calls "the Decibel Busting 15HP Siren").<br />
<br />
Darley is still partnered with Sentry today, and their sirens can be bought off of their eDarley website.<br />

}}<br />
<br />
The E.D. Bullard Company is a manufacturer of sirens that produced many different sirens throughout the 1930's and 40's. Based out of San Francisco, California, the company has been a manufacturer of industrial safety equipment since 1898. Just before and during WW2, they were contracted to make a variety of air raid and police sirens, some of which still survive to this day. While the company no longer makes sirens, the company is still around in 2022, making industrial safety equipment. The company was named after its founder, Edward Dickinson Bullard, and was formed in 1898. The company originally started with gold and silver mine safety equipment, and is credited with the invention of the hard hat in 1919. In the late 1930's, when WW2 was just beginning, the War Production Board contracted the company to create air raid sirens to defend the public from air raids. <br />
<br />
Bullard created a variety of different sirens, including a 12-port chain-driven rotational siren, a dual rotor 6-port siren, small vertical sirens, as well as a variety of police and emergency vehicle sirens. Bullard even created a large gasoline powered siren in partnership with Chrysler around 1941, and was the earliest iteration of what would later become the Chrysler Air Raid Siren. This 12-port gasoline siren was Bullard's very first attempt to meet the War Production board's requirements, and was deemed a failure and scrapped. Bullard's sirens can be told apart from every other siren manufacturer by their distinct conical rotors and stators. This design helped project sound forwards. The vast majority of Bullard's sirens are 12-port single tone, but some came in 6-port single tone as well. No dual tone Bullards are known to exist.<br />
E.D. Bullard also created coded variants of their sirens, including a dual rotor siren that uses a rotating stator ring that when powered, covers all of the ports and nearly silencing the siren instantly. This allows the siren to produce coded pulse signals. These units were 6-port single tone. These were mainly meant for use in fire stations, and none are known to still exist.<br />
<br />
After the war ended, sales of Bullard's sirens slowed as companies such as Federal Electric were proving dominant in the siren market across the United States. The company was never able to extend their range beyond California and the immediate surrounding states (and Hawaii), leading to the company ending production of their sirens sometime after 1945. After the war, most of the Bullard sirens continued to be used as air raid sirens during the Cold War, with the increasing threat of nuclear war requiring them. They were often supplanted by [[Scream Master]], [[Biersach & Niedermeyer Co.]] [[Mobil Directo]], [[B&M]] sirens, and [[Federal Signal]] [[SD-10]]'s. Once the Cold War ended, nearly every E.D. Bullard was finally disconnected as Californian cities decommissioned and abandoned their sirens. Many have since been removed, and today Bullard's sirens are quite uncommon. Very few active units exist, with one vertical unit known for being used as a drawbridge siren and several Model 3H27 "Weltex" units in Oregon and Ohio.<br />
<br />
== Model 3H27 ==<br />
E.D. Bullard also manufactured a siren without a conical rotor and stator, the Model 3H27. These are more commonly known by siren enthusiasts as "Weltex" sirens (it is unknown where this name originated), and are largely exclusive to the U.S. state of Oregon. These small omnidirectional sirens came in 9-port and 12-port single tone, and are very small motor-over-rotor vertical sirens with the motor on top and the rotor on the bottom. A cylindrical motor cover protects the motor, and is the same width as the stator. These sirens were available with a skirt to help project the sound outwards as well as a cylindrical mesh intake, and are suspended from below by a pair of metal supports on one side of the siren. The motor horsepower and decibel rating of these sirens are currently unknown, but they are confirmed to run on three-phase power.<br />

<br />
Scream Masters were a short-lived brand of sirens created by Robert J. Zievers, Inc. in La Verne, California. They were manufactured in the early 1950s as a local option for an omnidirectional air raid siren, with a rugged and low-maintenance design. Scream Masters are incredibly simple in design, with the siren's motor, rotor and stator standing underneath a large mesh and steel shroud, held up by two arms on the stator, very similar to the [[Federal Signal]] [[Model 5]]. They come with either 10HP or 15HP Square D Company motors running at 240V, and came in two different configurations: 6/8 port dual tone, and 9 port single tone. Like other sirens in California's CD systems, it came standard with a controller, maintenance basket, and large metal pole.<br />
<br />
R. J. Zievers, Inc. was reported in a 1954 Civil Defense Administration report to have also produced a 20HP dual headed rotational siren that boasted 125db at 100ft, heavily resembling the [[Federal Signal]] [[500 Series]] 500-DHTT. While at least a few of these were produced, and pictures exist of them, no rotating Scream Masters are known to exist today. They also produced a non-rotational variant of the siren. R.J. Zievers was also a dealer for Federal Signal's products, including mounting Federal's 500-DHTT on Scream-Master mounts. The same was also done with [[E. D. Bullard Co.]] rotational sirens. <br />
<br />
Scream Masters were mainly sold in California, with several cities having large systems that featured these alongside the [[Federal Signal]] [[500 Series]] 500-SHTT and [[Federal Signal]] [[SD-10]], [[HOR]] Siro-Drone, and [[Biersach & Niedermeyer Co.]] [[Mobil Directo]]. Due to being a small company, they never got to sell far beyond California. Along with sirens, R.J. Zievers, Inc also sold wind machines and other heavy machinery. While they proved to be very reliable sirens, R.J. Zievers Inc. just didn't have the funding or resources to compete against Federal, and production of the Scream Master series of sirens ended by the late 1950s as the [[Federal Signal]] [[500 Series]] 500-SHTT and [[Federal Signal]] [[SD-10]] proved to be better. Zievers himself died in April 1973, spelling the end of his company.<br />
<br />
Unfortunately, all Scream Master sirens were disconnected by the 1980s, along with the rest of California's Cold War civil defense system. While a few have been removed due to construction, many still remain on their poles, waiting for the day that they'll see action again. Evidently, a few are still connected to power and in operational condition, as a 9-port Scream Master was set off in the middle of the night by a vandal. Despite having sat inactive for over 40 years, the siren fired up with no issues, proving how reliable these are. With none in private possession, the recording of the vandalized Scream Master is the only way we know what these sound like, and that is likely to remain the case for a long time. Little else is known about them. No recordings exist of a 6/8 Scream Master, or the 20HP rotational.<br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
The Model 120 was originally created in 1982 as a custom built siren for the SONGS plant, which had strict requirements for its siren system. SONGS had gone through two other systems before this point, with a system of 39 [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and tested January 25th thru 27th, 1982. The Sentry sirens were found to perform terribly compared to what was advertised, leading to the sirens being removed an replaced. SONGS would then install a new system of 39 [[Federal Signal]] [[STL-10]]'s with those being installed by April of 1982 and tested in May of the same year. While the STL-10s performed significantly better than the Sentry sirens did, they still didn't meet the plant's needs. The only sirens on the market with enough range that would meet the plant's needs at the time were rotational sirens, but SONGS wanted to use exclusively omnidirectional sirens. So, they decided to design and create their own siren to meet their requirements.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in Summer 1982.]]<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in October 1982. Originally, the plan was after the first Model 120s were installed, a total of 52 additional Model 120s were going to replace the existing [[Federal Signal]] [[STL-10]]'s and making the system entirely Model 120s. This plan was dropped shortly afterwards due to the increasing delays and costs caused to the plant by not having a ready siren system by 1981 which was the original year planned for the plant's 2 newly constructed reactors to begin operating. Units #2 and #3 were ready to begin operation, but because the siren system was inadequate they couldn't begin operation until the Model 120s were installed. This caused a delay for over a year, as it also happened around the same time the NRC required nuclear plants to have siren systems. This also meant the plant's existing Unit #1 could not be restarted until the siren system was ready.<br />
<br />
There were 22 of these sirens produced, with one being never installed and put into storage as a spare. 16 of these were installed in October 1982 to add into the system of STL-10s, 8 of which indirectly swapped out with Model 120s with another 8 being brand new installs. 5 additional sirens were installed in 1988, one of which replaced a [[Federal Signal]] [[Thunderbolt]] that was an existing Civil Defense siren.<br />
<br />
After the Model 120s went up, in order to end the delays of the siren system not being up to par, SONGS opted to just keep the remaining [[Federal Signal]] [[STL-10]]'s and add 21 Model 120s in areas that need coverage to get the EPZ up to code for the plant's reactors to start. After a successful system test on May 4th, 1983, the plant's new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 being restarted. These delays, and the cost of the sirens themselves cost the plant over $1 million dollars.<br />
<br />
<br />
== Other Information ==<br />
<br />
For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba which made pneumatic sirens. The Model 120 is a Supercharged Electromechanical siren, but also more or less acts like a pneumatic siren due to the rotor lacking any vanes, meaning it requires an external air source to produce any meaningful sound, such as the [[Thunderbolt]] and [[Hurricane]]. The sound is created by a 4-port (later 5-port) single tone rotor, which spins inside the stator, which acts as a chamber to contain the air inside. The rotor is driven by a 2 Hp TEFC motor that runs at 3450 RPM. The siren has an 8-port stator with narrow ports, and the sound is then projected by 8 large fiberglass horns attached to the stator. The siren makes use of a belt driven Paxton centrifugal blower, that uses a 10 Hp TEFC motor which sits below the siren's head to force pressurized air up into the rotor. The 4-port units reached a frequency of 240 Hz (480 Hz without the blower) and the 5-port units reached 300 Hz. The rotor and stator are both coated in Teflon, which helps seal the air in and prevent leaks, while also helping to protect them from corrosion from the salty air. The rotor is 9.75 inches in diameter and including the stator, which it alone is over 2 inches in diameter, is in total 11.75 inches in diameter.<br />
<br />
<br />
<br />
By June of 2004, the plant began discussing a system replacement project due to the sirens suffering from advanced corrosion and degrading reliability due to the system's proximity to the ocean, along with the system "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by February 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. [[Whelen Engineering]] [[WPS-2800 series|WPS-2810]]'s and [[WPS-2800 series|WPS-2806]]'s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. <br />
<br />
These new electronic sirens have battery backup, are less maintenance due to their resistance to corrosion and no moving parts, and have similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ. These new sirens met the strict requirements of the plant without the need to specifically design a new siren as by the 2000s, there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County, Oregon to be used as tsunami sirens, 8 of which were installed, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in private possession currently under restoration to be brought back into operating condition.[[File:99F6BBFC-E550-4A8C-8538-82E2356B663A.jpeg|thumb|right|upright|Head of the privately owned unit with a salvaged motor attached.]]<br />

<br />
''B&M'' is a manufacturer of vehicular and civil defense sirens, and is one of the longest running siren manufacturers, having been in business since 1913. While they currently only offer vehicular sirens, B&M used to produce large outdoor warning sirens during World War II and the Cold War. With other siren manufacturers having a much larger presence, B&M eventually discontinued their line of outdoor warning sirens due to declining sales. They are still around today restoring and building vehicular sirens.<br />
<br />
B&M began making outdoor warning sirens sometime during the early 1930s, as patents for the 15-H-4 were filed in August of 1930. Advertisements also suggest they started building them in the 1930s. As World War II raged on and the Cold War loomed over the horizon, the demand for dual tone civil defense sirens was rising, to distinguish them from single tone fire sirens. B&M entered the market with a multitude of single and dual toned sirens, ranging from small single rotor sirens meant for tiny communities to large dual rotor sirens meant for big cities. These sirens had extremely efficient rotor designs, combining that with screaming high tones made for painfully loud sirens that can be heard for miles.<br />
<br />
<br />
== General Alarms ==<br />
<br />
=== 6GA ===<br />
The 6GA is B&M's smallest electric siren, being only 1/2 horsepower with a 6 inch, 6 port rotor, shared with the 6FA friction siren. Despite being so tiny, the 6GA has proven to be extremely loud for its size, with a privately owned unit reaching 130 dBA from up close. The 6GA was also referred to as the 6-AR-1, as it was also sold under the air raid siren lineup as a siren for compact suburban areas. 6GAs were sold with bell shaped shrouds to cover the siren, though earlier models were non-shrouded horizontal units with large intake horns. <br />
<br />
=== 8GA ===<br />
The 8GA is B&M's mid-size general alarm, equipped with an 8 inch, 8 port rotor, shared in design with the S8-B vehicular siren, apart from some minor changes to accommodate a standard shaft. They were sold with bell shaped shrouds to cover the siren. Few are known to exist in the wild, as the larger 10GA was a more popular choice.<br />
<br />
=== 10GA ===<br />
The 10GA is B&M's largest general alarm siren, utilizing a 2.5 horsepower motor to turn a 10 inch, 8 port rotor. Especially popular in Texas and surrounding states, the 10GA is one of B&M's more common outdoor sirens. It was also referred to as the Model 10 and the Model 10-AR-2 under B&M's air raid siren lineup, being the second smallest siren of the pack. They were sold with either bell shaped shrouds, partially exposed shrouding (similar to a Sentry [[Sentry Siren Incorporated|5V]]), or weatherproof screened shrouds, similar to a [[Scream Master]] or [[Federal Signal]] [[Model 5]]. The 10GA also ended up being the base for B&M's S10-B siren, a vehicular siren built solely for collectors. There is a good few active 10GA sirens, as well as a handful in private ownership. <br />
<br />
== Air Raid Sirens ==<br />
<br />
=== 15-AR-5 ===<br />
The B&M 15-AR-5 is the smallest dual end AR series siren, presumably with two 15 inch rotors being driven by a 5 horsepower motor. None are known to exist. It was best suited for smaller cities, according to B&M.<br />
<br />
=== 20-AR-7 ===<br />
The 20-AR-7 is the mid-size dual end AR series siren, with two 20 inch rotors powered by a 7.5 horsepower motor. A good few units still remain today, albeit inactive or under private ownership. They came in 16/20 port standard, and no remaining examples have a different port ratio. The 16/20 port units are unique by using 8/10 port rotors inside of 16/20 port stators, with the rotor having half the port count of the stators. It is believed B&M did this to get more equal sound distribution out of the intakes and ports, leading to more uniform coverage. This would create two octave tones, making for a very odd sounding siren. The 20-AR-7 was best suited for large cities, according to B&M. B&M also offered a single rotor version of this siren, called the '''20-AR'''. Four have been documented, and at least three exist today.<br />
<br />
=== 20-AR-10 ===<br />
The 20-AR-10 is B&M's largest AR series siren, with two 20 inch rotors, longer than what you see on a 20-AR-7, driven by a 10 horsepower motor. It was sold in 12/16 port with 6/8 port rotors, full 14/16 port, and possibly more. 5 examples remain today, one being only one 14 port rotor and the motor at B&M's facility, a display unit at an Orange County, CA fire station 46, Sierra Madre, CA's active unit, an inactive unit in Perris, CA, and another inactive unit in Carlisle, PA. The 20-AR-10 was best suited for widespread metropolitan areas, according to B&M. <br />
<br />
== H Series ==<br />
<br />
=== 15-H-2 ===<br />
The 15-H-2 is the smallest siren in the H Series lineup, being just 3 horsepower with two 15 inch rotors. The rotors are 6 port, and the stators are 12 port, making for an interesting octave tone despite being a single tone siren. Most likely because of it's price, the 15-H-2 was not a popular choice, being only $50 less than the 15-H-4 at the time. None are known to exist. <br />
<br />
=== 15-H-4 ===<br />
The 15-H-4 is the second siren in the H Series lineup, it has two 15 inch rotors driven by a 5 horsepower motor. The 15-H-4 is similar to the 15-H-2, just having longer rotors and a larger motor. Like the 15-H-2, the 15-H-4 is a 6/6 port siren with 12 port stators. All 15-H-4s known to exist have stator flanges for stator shrouds to be mounted, and one 15-H-4 in Kingman, AZ has horn extensions on the intakes. The 15-H-4 is the most common siren of the H Series, as it was the most reasonably priced, being much cheaper than the largest H Series siren. Three 15-H-4s are known to exist. B&M also made a vertical single rotor version of this siren, which was located in Bodega, CA. It has since been removed. <br />
<br />
=== 18-H-7 ===<br />
The 18-H-7 was the largest siren in the H series lineup, boasting two 18 inch rotors and a 10 horsepower motor. Not much is known about the 18-H-7, as it never sold well, likely due to being double the price of a 15-H-4. None have ever been documented, and none are known to exist today. <br />
<br />
B&M continued making these civil defense sirens up until somewhere in the 1960's, as the last documented installation was in 1965. It's likely that they couldn't keep up with competition from other manufacturers such as Federal or B&N, as B&M had poor advertising and high prices for their sirens. B&M ultimately opted to switch back to purely making vehicular sirens, which they continue to do to this day, along with restoring any siren you present to them. Today, there are few B&M civil defense sirens left, as all but one have been taken out of service due to age, replacement, or towns simply no longer having a need for them. However, their vehicular sirens and general alarm sirens can be found in widespread use. Only a single active B&M air raid siren remains, a 20-AR-10 located in Sierra Madre, CA. <br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' Community Alert Siren System was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />
<br />
Unlike most run of the mill Whelen systems that are mostly always activated by via radio, San Onofre's system was hardwired, and activated by via landline DTMF. This applied to both the legacy and latest systems. It is unknown why the system even from the start was not just radio activated, but it could be because either for security reasons, or the lack of repeater towers nearby or close to the area all the sirens are in, and there was already landline infrastructure in place before the original system was even installed.<br />

Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />
<br />
Unlike most run of the mill Whelen systems that are mostly always activated by via radio, San Onofre's system was hardwired, and activated by via landline DTMF. This applied to both the legacy and latest systems. It is unknown why the system even from the start was not just radio activated, but it could be because either for security reasons, or the lack of repeater towers nearby or close to the area all the sirens are in, and there was already landline infrastructure in place before the original system was even installed.<br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' Community Alert Siren System was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in October 1982 to add into a system of 39 [[Federal Signal]] [[STL-10]]'s that were installed in April 1982, 8 of which indirectly swapped out with Model 120s with another 8 installed as new locations, and later in 1988 5 additional locations were installed, one of which replacing a [[Thunderbolt]] that was actually a CD siren used by one of the cities before SCE took over it for use in their siren system. <br />
<br />
The reason these sirens were made is because there was no other siren available that would meet the plants needs, the system first started out with [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and was tested January 25th thru 27th, 1982 and proved to preform extremely poorly and the discussion was made to swap the 39 Sentries out for STL-10s by April 1982 with testing of them commencing by May the same year. STL-10 performance was significantly better, but still not good enough coverage wise. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. So the decision was made to design their own siren.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in Summer 1982.]]<br />
<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in October 1982, originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the remaining STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. <br />
<br />
This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the Sentries originally bought not meeting the plants needs by not effectively covering the EPZ, and the STL-10s still not being good enough, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. <br />
<br />
So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test in July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />

For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba which made pneumatic sirens. The Model 120 is a Supercharged Electromechanical siren, but also more or less acts like a pneumatic siren due to the rotor having no veins, meaning it requires an external air source to produce sound such as the [[Thunderbolt]] and [[Hurricane]]. The sound is chopped by a rotor, which sits inside a hollow cylinder, or stator, which acts as a chamber to contain the air inside. 8 Small narrow slots on the stator allow the sound to come out. The sound is then projected by 8 large fiberglass horns. It consists of a belt driven Paxton blower, that uses a 10 Hp TEFC motor which sits below the siren's head. The rotor is 9.75 inches in diameter and has 5 ports. Including the stator it is in total 11.75 inches in diameter. The rotor is powered by a 2 Hp TEFC motor that spins at 3450 RPM. <br />
<br />
<br />
By 6/10/2004, the plant was discussing a system replacement project due to saying the current system is "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by Febuary 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. [[Whelen Engineering]] [[WPS-2800 series|WPS-2810]]'s and [[WPS-2800 series|WPS-2806]]'s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. <br />
<br />
These new electronic sirens have battery backup, are less maintenance, and have similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ, and as for the strict requirements of the original system, that was no longer an issue as by the 2000s there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County Oregon to be used as tsunami sirens, 8 of which were installed, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in private possession currently under restoration to be brought back into operating condition.[[File:99F6BBFC-E550-4A8C-8538-82E2356B663A.jpeg|thumb|right|upright|Head of the privately owned unit with a motor attached.

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in July 1983 to add into a system of 39 [[Federal Signal]] [[STL-10]]'s that were installed in April 1982, 8 of which indirectly swapped out with Model 120s with another 8 installed as new locations, and later in 1988 5 additional locations were installed, one of which replacing a [[Thunderbolt]] that was actually a CD siren used by one of the cities before SCE took over it for use in their siren system. <br />
<br />
The reason these sirens were made is because there was no other siren available that would meet the plants needs, the system first started out with [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and was tested January 25th thru 27th, 1982 and proved to preform extremely poorly and the discussion was made to swap the 39 Sentries out for STL-10s by April 1982 with testing of them commencing by May the same year. STL-10 performance was significantly better, but still not good enough coverage wise. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. So the decision was made to design their own siren.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.]]<br />
<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in March 1983, originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the remaining STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. <br />
<br />
This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the Sentries originally bought not meeting the plants needs by not effectively covering the EPZ, and the STL-10s still not being good enough, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. <br />
<br />
So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test in July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' Community Alert Siren System was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' sirens was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone supercharged electromechanical siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in July 1983 to add into a system of 39 [[Federal Signal]] [[STL-10]]'s that were installed in April 1982, 8 of which indirectly swapped out with Model 120s with another 8 installed as new locations, and later in 1988 5 additional locations were installed, one of which replacing a [[Thunderbolt]] that was actually a CD siren used by one of the cities before SCE took over it for use in their siren system. <br />
<br />
The reason these sirens were made is because there was no other siren available that would meet the plants needs, the system first started out with [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and was tested January 25th thru 27th, 1982 and proved to preform extremely poorly and the discussion was made to swap the 39 Sentries out for STL-10s by April 1982 with testing of them commencing by May the same year. STL-10 performance was significantly better, but still not good enough coverage wise. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. So the decision was made to design their own siren.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.]]<br />
<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in March 1983, originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the remaining STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. <br />
<br />
This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the Sentries originally bought not meeting the plants needs by not effectively covering the EPZ, and the STL-10s still not being good enough, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. <br />
<br />
So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test in July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />
<br />
== Other Information ==<br />
<br />
For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba which made pneumatic sirens. The Model 120 is a Supercharged Electromechanical siren, but also more or less acts like a pneumatic siren due to the rotor having no veins, meaning it requires an external air source to produce sound such as the [[Thunderbolt]] and [[Hurricane]]. The sound is chopped by a rotor, which sits inside a hollow cylinder, or stator, which acts as a chamber to contain the air inside. 8 Small narrow slots on the stator allow the sound to come out. The sound is then projected by 8 large fiberglass horns. It consists of a belt driven Paxton blower, that uses a 10 Hp TEFC motor which sits below the siren's head. The rotor is 9.75 inches in diameter and has 5 ports. Including the stator it is in total 11.75 inches in diameter. The rotor is powered by a 2 Hp TEFC motor that spins at 3450 RPM. <br />
<br />
<br />
By 6/10/2004, the plant was discussing a system replacement project due to saying the current system is "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by Febuary 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. [[Whelen Engineering]] [[WPS-2800 series|WPS-2810]]'s and [[WPS-2800 series|WPS-2806]]'s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. <br />
<br />
These new electronic sirens have battery backup, are less maintenance, and have similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ, and as for the strict requirements of the original system, that was no longer an issue as by the 2000s there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County Oregon to be used as tsunami sirens, 8 of which were installed, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in the possession of Aaron Allevato (Duderocks5539) and Edaan Friedman and currently under restoration to be brought back into operating condition.[[File:99F6BBFC-E550-4A8C-8538-82E2356B663A.jpeg|thumb|right|upright|Head of the privately owned unit with a motor attached.

The '''San Onofre Nuclear Generating Station (SONGS) ''' sirens was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006. Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone pneumatic siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in July 1983 to add into a system of 39 [[Federal Signal]] [[STL-10]]'s that were installed in April 1982, 8 of which indirectly swapped out with Model 120s with another 8 installed as new locations, and later in 1988 5 additional locations were installed, one of which replacing a [[Thunderbolt]] that was actually a CD siren used by one of the cities before SCE took over it for use in their siren system. <br />
<br />
The reason these sirens were made is because there was no other siren available that would meet the plants needs, the system first started out with [[Sentry Siren Incorporated]] [[10V]]'s, [[5V]]'s, and [[3V8]]'s installed in August 1981 and was tested January 25th thru 27th, 1982 and proved to preform extremely poorly and the discussion was made to swap the 39 Sentries out for STL-10s by April 1982 with testing of them commencing by May the same year. STL-10 performance was significantly better, but still not good enough coverage wise. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. So the decision was made to design their own siren.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.]]<br />
<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in March 1983, originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the remaining STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. <br />
<br />
This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the Sentries originally bought not meeting the plants needs by not effectively covering the EPZ, and the STL-10s still not being good enough, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. <br />
<br />
So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test in July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />
<br />
== Other Information ==<br />
<br />
For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba, who also made pneumatic sirens. The Model 120 is a Pneumatic siren, meaning it requires an external air source to produce sound. The sound is chopped by a rotor, which sits inside a hollow cylinder, or stator, which acts as a chamber to contain the air inside. 8 Small narrow slots on the stator allow the sound to come out. The sound is then projected by 8 large fiberglass horns. It consists of a belt driven Paxton blower, that uses a 10 Hp TEFC motor. The rotor is 9.75 inches in diameter and has 5 ports. Including the stator it is in total 11.75 inches in diameter. The rotor is powered by a 2 Hp TEFC motor that spins at 3600 RPM. <br />
<br />
By 6/10/2004, the plant was discussing a system replacement project due to saying the current system is "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by Febuary 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. Whelen WPS 2810s and WPS 2806s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. <br />
<br />
These new electronic sirens have battery backup, are less maintenance, and having similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ, and as for the strict requirements of the original system, that was no longer an issue as by the 2000s there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County Oregon to be used as tsunami sirens, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in the possession of Aaron Allevato (Duderocks5539) and Edaan Friedman and currently under restoration to be brought back into operating condition.[[File:99F6BBFC-E550-4A8C-8538-82E2356B663A.jpeg|thumb|right|upright|Head of the privately owned unit with a motor attached.

Last test of the old system before replacement was October 26th, 2005. And last test of the latest system before not being fully tested anymore was October 15th, 2014. <br />

The ''' SoCal Edison (SCE) 120 ''' or ''' Model 120 ''' was a 120 dB low tone pneumatic siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the ''' [[San Onofre Nuclear Generating station]] '''.<br />
<br />
== History ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in July 1983 to add into a system of 39 Federal Signal STL-10s that were installed in April 1982, 8 of which indirectly swapped out with Model 120s with another 8 installed as new locations, and later in 1988 5 additional locations were installed, one of which replacing a Thunderbolt that was actually a CD siren used by one of the cities before SCE took over it for use in their siren system. <br />
<br />
The reason these sirens were made is because there was no other siren available that would meet the plants needs, the system first started out with Sentry 10V's, 5V's, and 3V8's installed in August 1981 and was tested January 25th thru 27th, 1982 and proved to preform extremely poorly and the discussion was made to swap the 39 Sentries out for STL-10s by April 1982 with testing of them commencing by May the same year. STL-10 performance was significantly better, but still not good enough coverage wise. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. So the decision was made to design their own siren.<br />
<br />
[[File:Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.jpeg|thumb|left|upright|Model 120 prototype being mounted to an existing STL-10 pole for range and output testing in 1982.]]<br />
<br />
<br />
Starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in March 1983, originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the remaining STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. <br />
<br />
This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the Sentries originally bought not meeting the plants needs by not effectively covering the EPZ, and the STL-10s still not being good enough, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. <br />
<br />
So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test in July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />
<br />
== Other Information ==<br />
<br />
For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba, who also made pneumatic sirens. The Model 120 is a Pneumatic siren, meaning it requires an external air source to produce sound. The sound is chopped by a rotor, which sits inside a hollow cylinder, or stator, which acts as a chamber to contain the air inside. 8 Small narrow slots on the stator allow the sound to come out. The sound is then projected by 8 large fiberglass horns. It consists of a belt driven Paxton blower, that uses a 10 Hp TEFC motor. The rotor is 9.75 inches in diameter and has 5 ports. Including the stator it is in total 11.75 inches in diameter. The rotor is powered by a 2 Hp TEFC motor that spins at 3600 RPM. <br />
<br />
By 6/10/2004, the plant was discussing a system replacement project due to saying the current system is "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by Febuary 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. Whelen WPS 2810s and WPS 2806s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. <br />
<br />
These new electronic sirens have battery backup, are less maintenance, and having similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ, and as for the strict requirements of the original system, that was no longer an issue as by the 2000s there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s.<br />
<br />
After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County Oregon to be used as tsunami sirens, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in the possession of Aaron Allevato (Duderocks5539) and Edaan Friedman and currently under restoration to be brought back into operating condition.[[File:99F6BBFC-E550-4A8C-8538-82E2356B663A.jpeg|thumb|right|upright|Head of the privately owned unit with a motor attached. As you can see it looks exactly the same as the unit in the photo above, just without the horns and frame assembly. The motor is not the exact same motor as the other ones that were installed, but is the same rating, Horsepower, and RPMs.]]<br />

The Modulator was an electronic siren produced by [[Federal Signal Corporation]]. It is modular, containing a variable number of cells. Each active cell contains up to four 100W compression drivers and directs sound downward to the top of the cell below it, where it is redirected outward. The bottom-most cell is a dummy to direct sound from the lowest active cell.<br />
<br />
== Models ==<br />
The model number refers to the number of active cells, minus the bottom dummy cell, and drivers, of which a cell can have up to four. The first digit refers to the number of active cells in the siren and the last two refer to the number of drivers. For instance, the MOD2008 has two active cells with four drivers each, making eight drivers, plus a dummy cell on the bottom.<br />

The '''San Onofre Nuclear Generating Station (SONGS) ''' sirens was a network of 50 sirens located within a 10-mile radius of the now shut down San Onofre Nuclear Generating Station located just past San Clemente, California. There were 24 [[WPS-2800 series|WPS-2810]] , and 26 [[WPS-2800 series|WPS-2806]], sirens. These sirens were activated by the four Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, San Clemente, and MCAS Camp Pendleton which are all located in South Orange County.<br />
<br />
The system was lasted tested fully on October 15th, 2014 due to SONGS being decommissioned (which was announced in June 2013), and the NRC not requiring full tests anymore. So after that, the system has only been booped/growl tested in each jurisdiction one by one every June from June 2015 to June 2018 since the plant was still in charge of them, and had to make sure they were still working in case the cities needed to use them for other emergencies. But in late 2018, it was announced that SONGS will no longer be in charge of the system after June 30th, 2019. <br />
<br />
The cities were given the option to keep them and maintain and test them for themselves shortly after the plant announced their plan with the sirens, but 2 out of the 4 decided to keep them which is the 10 on MCAS Camp Pendleton and the 8 in Dana Point, but opted to remove one location completely and replace the 2800s, but keeping the original poles, so because of this, the plant did not do boop tests for June 2019. On July 1st, 2019, all the sirens were deactivated, and a few months later in December 2019, they were gradually removed. <br />
<br />
<br />
All 9 sirens located in San Juan Capistrano were completely removed and all 17 sirens in San Clemente were removed as well, but the poles that have street lights and high voltage power lines attached are the only poles that remain in those 2 cites. Dana Point kept 7 out of the 8 poles, but removed the 2800 heads and cabinets, with 1 being removed completely along with its pole. <br />
<br />
As of February 2020, the poles in Dana Point remain empty with no siren or equipment mounted on them, but new sirens will be up on the poles eventually, and they will be used for emergencies such as tsunamis. San Clemente is doing the same thing as San Juan Capistrano, except San Clemente has 19 sirens, (The most sirens out of any other city in the 10-mile radius of SONGS.) They will only be keeping poles that have street lights on them, and poles that support electrical lines. MCAS Camp Pendleton kept their 10 existing 2800s, and is now tied in with their system of Cooper WAVES sirens. <br />
<br />
<br />
All sirens in the system ran on 435 HZ ESC-2020s, but around 2012, some had their ESC-2020 cabinets ungraded to ESC-2030 logic boards that were 560 HZ. This plant used to have [[Model 120]] and [[STL-10]] Sirens, that were gradually replaced by the Whelens starting in November 2005, and completed in December 2005/January 2006.

The SoCal Edison (SCE) 120 or Model 120 was a 120 dB low tone pneumatic siren designed in house by Southern California Edison for use within the 10 Mile Emergency Planning Zone (EPZ) for the San Onofre Nuclear Generating Station (SONGS).<br />
<br />
== Origins ==<br />
<br />
There were 22 of these sirens produced with one being never installed which is now privately owned. 16 were installed in July 1983 to add into a system of 32 Federal Signal STL-10s that were installed in April 1982 with 2 of the STL-10s being swapped out for Model 120s, and later in 1988 5 additional locations were installed one of which replacing a Thunderbolt that was actually a CD siren used by one of the cities before SONGS took over it for use in their siren system. The reason these sirens were made is because there was no other siren available that would meet the plants needs. The only sirens that were available on the market that have the range the plant was looking for were rotating directional sirens only, of which the plant wanted Omnidirectional only sirens. They did look into ACA Cyclones which was the most powerful omnidirectional siren available, but they realized it didn't have the coverage the plant wanted being about 3,000 or so feet less then the plants range requirement, and the fact that they have massive 50 Hp motors which was overkill for a siren with such a range of only about 4,000ish feet. The other reason is because the STL-10s underperformed in all areas they were placed in, as well as federal lying to SoCal Edison about the STL-10 being 120 decibels and having the specific effective range that the plant required (which was about 6,000 or more feet effective range) to cover the EPZ due to the hilly terrain of the jurisdictions in the EPZ. <br />

So starting in around June 1982, Model 120 prototypes started to be constructed and tested, with the final designed units being completed in March 1983, and the first 16 installed in July 1983, and later on 5 more in 1988 to cover new housing and business development in a part of the city of San Clemente that was being constructed around 1987 bringing the total to 21 Model 120s and a total number of 52 sirens with the already existing 32 STL-10s. <br />
Originally the plan was after the Model 120s were installed, a now total of 52 sirens were going to be all Model 120s which means swapping out the existing 32 STL-10s with 120s making the system Model 120's only, but this plan was dropped shortly afterwards and only about 8 Model 120s ended up swapping out STL-10s with the other ones being new locations that didn't replace STL-10s. This was due to the whole siren thing causing delays to the plant by not having a ready siren system by 1981 which was the original year for the plants 2 new reactors that just finished construction, Units #2 and #3 to begin operation, but due to the STL-10s originally bought not meeting the plants needs by not effectively covering the EPZ, they had to find another siren that meets the plants needs in order for the plants new reactors to start operations which caused a delay for over a year, this also happened around the same time the NRC required Nuclear plants to have siren systems, but until SONGS get sirens that can perfectly cover the 10 mile EPZ, the plants new reactors could not begin operations, and the plants original reactor that was the first reactor to be built in 1968 (Decommissioned in 1992 and completely demolished by 2006) Unit #1 could not be restarted until the siren system is fully operational and effectively covers the EPZ. So after the Model 120s went up, to end the delays of the siren system not being up to par, which costed over $1 million per day that held up the plant from starting, it was decided to just keep the underperforming STL-10s and just add 21 Model 120s in areas that need coverage to get the EPZ effectiveness up to code for the plants original reactor to restart, and the new reactors to start. After a successful system test around late July 1983, the plants new reactors began operation shortly afterwards with Unit #2 starting on August 8th, 1983, and Unit #3 on April 1st, 1984, as well as Unit #1 restarted.<br />

For around a decade, they were thought to be "Toshiba" sirens, because they were pneumatic and people just assumed they were made by Toshiba, who also made pneumatic sirens. The Model 120 is a Pneumatic siren, meaning it requires an external air source to produce sound. The sound is chopped by a rotor, which sits inside a hollow cylinder, or stator, which acts as a chamber to contain the air inside. 8 Small narrow slots on the stator allow the sound to come out. The sound is then projected by 8 large fiberglass horns. It consists of a belt driven Paxton blower, that uses a 10 Hp TEFC motor. The rotor is 9.75 inches in diameter and has 5 ports. Including the stator it is in total 11.75 inches in diameter. The rotor is powered by a 2 Hp TEFC motor that spins at 3600 RPM. By 6/10/2004, the plant was discussing a system replacement project due to saying the current system is "aging", and a year later starting In November 2005, (a month after the annual siren test), the Model 120s and the STL-10s started to be gradually removed and replaced, and by Febuary 2006 all have been replaced marking October 26th, 2005 as the final test of the original system, as well as the end of the one of a kind original system that stood out from all other Nuclear plant systems. Whelen WPS 2810s and WPS 2806s were installed in their places. The 2810s went in place of the Model 120s and the 2806s went in place of the STL-10s. These new electronic sirens have battery backup, are more efficient, less maintenance, and having similar ranges to the original system such as the 2806s having better range compared to the STL-10s, and the 2810s having close to the same range but about 2,000 feet less range compared to the the Model 120, but still enough range to cover the EPZ, and as for the strict requirements of the original system, that was no longer an issue as by the 2000s there was commercially produced omnidirectional sirens that have close to the same range as the Model 120 and as well have better range then the STL-10s. After all the old sirens have been removed and replaced, SONGS sold 23 of the STL-10s to Curry County Oregon to be used as tsunami sirens, and the Model 120s and remaining 5 STL-10s are believed to have been scrapped, but its unknown if they were, or went somewhere else but hasn't been discovered. The only Model 120 that is known and remaining is in the possession of Aaron Allevato (Duderocks5539) and Edaan Friedman and currently under restoration to be brought back into operating condition.<br />
