TYFONIC ET 30/3

The TYFONIC ET 30/3 (also known as just the TYFONIC ET 30) is an omnidirectional electronic siren and the smaller variant of the TYFONIC ET 60. The siren is made up of 3 TYFON speakers made of impact resistant thermoplastic, which are recessed into a short triangular plastic-covered galvanized sheet steel housing. The housing contains the siren's wiring, as well as its speaker compression drivers. A small cylindrical mount is located below the housing, and allows the siren to be mounted to a pipe. The TYFONIC ET 30/3 uses 125 W speaker drivers, in total using 375 W of power. The siren's operating temperature range is -30-+60°C (22°F-+140°F).

TYFONIC ET 60

The TYFONIC ET 60 is an omnidirectional electronic siren and the larger cousin of the TYFONIC ET 30/3. The siren is made up of 6 TYFON speakers made of impact resistant thermoplastic attached to a tall triangular plastic-covered galvanized sheet steel housing. The housing contains the siren's wiring, as well as its speaker compression drivers. A small cylindrical mount is located below the housing, and allows the siren to be mounted to a pipe. The TYFONIC ET 60 uses 125 W speaker drivers, in total using 750 W of power. The siren's operating temperature range is -30-+60°C (22°F-+140°F).

TYFONIC ET 500

The TYFONIC ET 500 is the only omnidirectional electronic siren in the series, taking the form of a stacked-cell modular siren. This siren is Kockums Sonics' answer to Federal Signal's Modulator, Whelen's WPS 2700-2900 and ACA's Quadren (now the ASC i-FORCE). The TYFONIC ET 500 / 1M mobile unit is Mobile version for Normal ET500 With the Strobe in it top(optional) Non-Mobile Mount version and With Mobile Mount version(Also optional), The siren is mainly as a public address loudspeaker and/or as a mobile alert. Amplifier TK 150 MkII is based on digital signal processing, and thus allows audio files to be stored in the common wav format. Siren sounds can be easily downloaded to the amplifier via the USB connection at the rear. Spoken messages through the connected microphone or as audio files previously loaded onto the amplifier permit the rapid communication of information in case of accident or other incidents. Simple connection to a 12 V power output in the vehicle and a vehicle roof connector employing magnetic fixings on the sound emitter shorten mounting time. The vehicle roof connector with magnetic fixings has been tested at different speeds and has a good safety margin at 80 km/h. Optimum speech intelligibility is achieved at a speed of 20 km/h or lower, but the Some units use the TK-500 Controller and another use the TK 150 MkII mobile controller and The siren's operating temperature range is -30-+60°C (22°F-+140°F), The TYFONIC ET 500 / 1M mobile unit reaches 122 dB(A) @ 1 m and the siren is growing in market.

TYFONIC ET 751

The TYFONIC ET 751 is a bi-directional electronic siren made up of 3, 4, or 6 TYFON speakers made of impact resistant thermoplastic attached to a tall rectangular plastic-covered galvanized sheet steel housing; for 3-speaker units, the speakers are all arranged on one side of the housing. For 4 and 6-speaker units, an equal amount of horns are arranged on both sides of the housing. The 4-speaker option seems to have been the most popular, as very few units with 3 or 6 speakers are known to exist. The housing contains the siren's wiring, as well as its speaker compression drivers. A small cylindrical mount is located below the housing, and allows the siren to be mounted to a pipe. The TYFONIC ET 751 uses 125 W speaker drivers, supporting up to 750 W of power. A variant of the siren exists with several differences, most notably a lower pitch. These units' housings are painted red and are referred to as TYFONIC Type ET 751-2s on the tag. The siren's operating temperature range is -30-+60°C (22°F-+140°F). The 3-speaker TYFONIC ET 751 reaches 110 dB @ 30 m (~100 ft), though the decibel ratings for the other speaker counts are unknown.
