The Large Electromechanical Sirens series is a series of electromechanical sirens produced by Taizhou Lion King Signal, or simply Lion King, based in the People's Republic of China. The series was first introduced sometime in the mid-to-late 2000s and for the most part, has been produced ever since.
The series is split up into 3 main sub-series and several smaller ones, these being the:
Vertical Mounting Sirens
Model LK-M
Model LK-M2
The Model LK-M2 is Lion King's imitation/rebrand of Federal Signal's Model 2. The siren is virtually identical to that of its original counterpart, utilizing the same design, with a 1.5 kW (2 hp), 50/60 Hz, 110, 220, 230, or 240 V AC motor that drives a small, 5-port single-tone chopper. The rotor on the Model LK-M2 is open on both the top and bottom, which allows the siren to intake on either side of the rotor to maximize airflow through the chopper.
The siren uses a simple, stainless-steel housing with a rain shield on top, which protects the siren from the elements, and 2 louvers below it which direct the sound downwards. The siren reaches 123 dB @ 1 m (3 ft). The Model LK-M2 is essentially the same as an original Model 2, though the Model LK-M2's build quality is comparatively worse, using a poor-quality motor and brushes. This results in the siren declining in pitch during operation. Another difference would be branding; Lion King's logo is on the siren's upper half as opposed to Federal's. Aside from these differences, they are effectively the same siren.
Model LK-M5
The Model LK-M5 is Lion King's (now discontinued) imitation/rebrand of Federal Signal's C3 1/2, more specifically a Model 5. The siren replicates that of a C3 1/2, utilizing the same general housing design. The siren is protected by a rain shield on top of the housing, with a small eyebolt on top, while a skirt surrounding the midsection of the housing directs (or is supposed to direct) the sound downwards. There are 4 openings beneath the rain shield and skirt (which are much wider compared to the siren's original counterpart), with all of them covered by a stainless-steel screen.
Unlike the C3 1/2, the Model LK-M5's rain shield and skirt are the same width. The entirety of the housing is made of stainless steel. Despite the housing bearing the look, the siren is a modified Model LK-JDL480 at its core, which is 10-port and driven by a 4 kW (5 hp), 50/60 Hz, 380, 400, or 440 V AC motor. This renders the skirt useless as the Model LK-JDL480 is too short for the skirt to effectively project anything. Lion King likely couldn't get their hands on the casting pattern for the C3 1/2, as it was discontinued long before the Model LK-M5's introduction. The siren reaches 130 dB @ 1 m (3 ft). The Model LK-M5 would be discontinued sometime in the mid-2010s, likely due to being redundant.
Model LK-JDL
Model LK-JDL400
The Model LK-JDL400 is an omnidirectional, electromechanical siren, and the smallest siren in the Model LK-JDL subseries. Relatively simple in design, the Model LK-JDL400 consists of a 10-port rotor and stator. The rotor is driven by a 2.2 kW (3 hp), 50/60 Hz, 220, 240, 380, 400, or 440 V AC 1 or 3 ph motor. A large, thin rain shield is bolted above the stator, which protects the siren from the elements. A small eyebolt is located above the rain shield. The siren sits upon a small stand below the motor with 4 holes on each side, allowing for the siren to be bolted down. The Model LK-JDL400 reaches 123 dB @ 1 m (3 ft).
Model LK-JDLD400
The Model LK-JDLD400 is an omnidirectional, electromechanical siren, and was formerly one of the smallest sirens in the Model LK-JDL subseries. Relatively simple in design, the Model LK-JDL400 consists of a 10-port rotor and stator. The rotor is driven by a 2.2 kW (3 hp), 50/60 Hz, 220, 240, 380, 400, or 440 V AC 1 or 3 ph motor.

Model LK-STH10A
The Model LK-STH-10A is one of Lion King's imitations/rebrands of Federal Signal's STH-10, utilizing the same general design. The siren is relatively simple in design, consisting of a 10-port rotor and stator, as opposed to the STH-10, which is 12-port. The rotor is driven by a 4 kW (5.3 hp), 50/60 Hz, 380, 400, or 440 V AC motor, unlike the STH-10's 7.5/10 hp one. The motor is protected by a cylindrical housing with a rain shield above it. There are 10 horns on the siren, attached to each stator port. 10 stainless steel beams connect the horns. 10 more stainless steel beams are attached to the housing and connect to the beams connecting the horns. The siren has a cylindrical, tubular intake located below the siren, in between the siren's 3 included mounting legs. The Model LK-STH10A is completely made out of stainless steel. The siren reaches 136 dB @ 1 m (3 ft).
Model LK-STH10B
The Model LK-STH-10B is one of Lion King's imitations/rebrands of Federal Signal's STH-10, utilizing the same general design. The siren is relatively simple in design, consisting of a 10-port rotor and stator, as opposed to the STH-10, which is 12-port. The rotor is driven by a 4 kW (5.3 hp), 50/60 Hz, 380, 400, or 440 V AC 3 ph motor, unlike the STH-10's 7.5/10 hp one. The Model LK-STH10B is completely made out of stainless steel. There are 10 horns on the siren, attached to each stator port. Interestingly, The Model LK-STH10B uses a rotor-over-motor configuration. The motor is protected by a cylindrical housing below the stator, with the 3 mounting legs below it. The shroud and eyebolt used on the Model LK-JDL480 are also present on the Model LK-STH10B, located above the stator. The siren reaches 135 dB @ 1 m (3 ft).
Model LK-STH10H
The Model LK-STH-10H is Lion King's (now discontinued) imitation/rebrand of ASC's T-121, despite what the siren's name suggests. The siren is relatively simple in design, consisting of an 11-port rotor and stator, as opposed to the 8-port T-121, driven by a 4 kW (5.3 hp), 50/60 Hz, 380, 400, or 440 V AC motor. A rounded housing above the stator protects the motor. There are 11 T-121-esque horns on the siren, attached to each stator port. The intake and mounting legs are sourced from Federal's STH-10. The Model LK-STH10H was discontinued early into production, sometime in the early 2010s. It is, however, still sold by Lion King's various resellers. The siren reaches 140 dB @ 1 m (3 ft).
Model LK-STH21-2
The Model LK-STH21-2 is Lion King's imitation/rebrand of Sentry's 10V2T, despite what the siren's name suggests. The siren consists of a 10 and 11-port rotor and stator (as opposed to the 8 and 16-port rotors and stators on the 10V2T), both driven by a 7.5 kW (10 hp), 50/60 Hz, 380, 400, or 440 V AC motor, protected by a stainless steel housing. There are 21 horns on the siren, attached to each stator port. The top row of horns is slightly larger than the bottom row. 4 legs above the stator hold up the siren's rain shield, which also has an eyebolt on top of it. This assembly functions as the siren's intake. Below the 11-port stator, a Sentry-esque 5-legged mount/intake is also present. Mesh screens protect the top and bottom intakes. The siren reaches 137 dB @ 1 m (3 ft).
Model LK-EP400
The Model LK-EP400 is a (now discontinued) unusual electric/pedal-powered siren, consisting of a chassis that holds the rotor and stator (which is reused from the Model LK-JDL450, the motor, as well as 4 bicycle-esque seats and handlebars with pedals below them. The pedals are connected to several gears, which in turn are connected to the stator. The siren, if needed to be run via pedals, requires 4 people to operate. A 1.5 kW (2 hp), 50/60 Hz, 380, 400, or 440 V AC motor setup is connected to the rotor and is intended to be the standard method of operating the siren. The Model LK-EP400 was discontinued early into production, likely sometime in the early 2010s. The siren reaches 127 dB @ 1 m (3 ft).
Horizontal Mounting Sirens
Model LK-JDW
Model LK-JDW400
The Model LK-JDW400 is a dual-rotor omnidirectional siren and the smallest option in the sirens that are a part of the Model LK-JDW subseries and fall under the Large Electromechanical Sirens series. Extremely simple in design, the Model LK-JDW400 consists of 2 10-port rotors and stators, each driven by a dual-ended 4 kW (5.3 hp), 50/60 Hz, 380, 400, or 440 V AC motor. 10 beams are in front of each of the stators, with each connecting to a large cylindrical center, likely to make it harder for birds to nest into the rotors. A grille is also present behind the beams. The siren is mounted upon a small rectangular base, with 4 holes in each corner, allowing for the siren to be mounted. The siren reaches 129 dB @ 1 m (3 ft).

A grille is also present behind the beams. The siren is mounted upon a small rectangular base, with 4 holes in each corner, allowing for the siren to be mounted. The siren reaches 133 dB @ 1 m (3 ft).
Model LK-JDW450-2
The Model LK-JDW450-2 is a (now discontinued) dual-rotor omnidirectional siren and was one of the largest options in the sirens that are a part of the Model LK-JDW subseries and fall under the Large Electromechanical Sirens series. Extremely simple in design, the Model LK-JDW450-2 consists of a 10 and 11-port rotor and stator, each driven by a dual-ended 7.5 kW (10 hp), 50/60 Hz, 380, 400, or 440 V AC 3 ph motor. 10 beams are in front of each of the stators, with each connecting to a large cylindrical center, likely to make it harder for birds to nest into the rotors. A grille is also present behind the beams. The siren is mounted upon a small rectangular base, with 4 holes in each corner, allowing for the siren to be mounted. Some Model LK-JDW450-2 units have slight cosmetic differences between the 10 and 11-port rotors. The Model LK-JDW450-2 was discontinued early into production, likely sometime in the early 2010s. The siren reaches 134 dB @ 1 m (3 ft).
DC Sirens
Model LK-2001
The Model LK-2001, formerly the Model LK-SENTRY A, is Lion King's imitation/rebrand of Federal Signal's 2001-SRNB. The siren is virtually identical to that of its original counterpart, utilizing the same design. The siren's rotor and stator are located in the horn, just behind the nose cone. Unlike nearly every other siren, the chopper on the Model LK-2001 faces backward, with the siren's 4.875 kW (7 hp) 48 V DC 100 A motor being located inside the nose cone. The rotor and stator are the same as Federal's long-discontinued C1 1/2 Model 3, coming exclusively in 12-port single tone with small "throats" attached to the stator ports which direct the sound up and forwards out into the horn of the siren. This is all attached to the square main housing located behind the horn, which contains the collector ring tube and wiring.
The siren's dual intakes are located on the bottom of the housing, protected by mesh screens. The top of the housing has a slightly pyramid-shaped protrusion, which prevents rainwater from pooling on top of the housing and rusting through. The Model LK-2001, like the 2001-SRNB, has a cube-shaped direct-drive rotator. The siren is equipped with battery backup. Aside from quality, the only real difference between this siren and the 2001-SRNB is the branding; Lion King removed the SRNB label on the rotor and replaced Federal Signal's logo with theirs. The siren was originally named the LK-SENTRY A, alongside Lion King's Eclipse8 imitation/rebrand, which was named the LK-SENTRY B. This was changed sometime during the mid-2010s when the siren was renamed to the LK-2001 and the LK-SENTRY B was discontinued. The siren reaches 128 dB @ 30 m (100 ft).
Model LK-SENTRY
Model LK-SENTRY B
The Model LK-SENTRY B is Lion King's (now discontinued) imitation/rebrand of Federal Signal's ECLIPSE8. The siren is virtually identical to that of its original counterpart, utilizing the same design. It consists of an 8-port rotor and stator, driven by a 5.25 kW (7 hp) 48 V DC motor. The siren has 8 rectangular horns, attached to each stator port. The siren has a cylindrical, tubular intake located below the siren, in between the siren's 3 included mounting legs. The entire siren is made out of stainless steel. Unlike the siren's original counterpart, the Model LK-SENTRY B has a small, square base located below the 3 mounting legs. The siren is equipped with battery backup. The Model LK-SENTRY B was discontinued early into production, likely sometime in the early 2010s. The siren reaches 115 dB @ 30 m (100 ft).
