The Edwards EWS-V7 Series is large enough to tackle almost any application. Taking advantage of a continuous duty industrial motor and rated at 124 dB, the EWS-V7 is an omni-directional siren which produces continuous 360 degree coverage, making it a superior alternative to a directional beam type siren.

The EWS-V7 is available in either single or three phase power, and is a dual tone siren, employing two rotors with different numbers of ports to produce a greater range of frequency. One rotor produces 460 cycles per second, and the other produces 920 cycles per second. All exposed siren components are of metal construction, which are "powder coated" for the most durable finish available. The fan and housing are made of non-corrosive cast aluminum. Maximum diameter is 78" (198.1 cm), maximum height is 56" (142.2 cm), and the maximum mounting base dimension is 19" (48.3 cm) square. Shipping weight of the siren alone is 750 lbs (340.2 kg)
