Designed for medium or small, growing communities this siren is a true workhorse. It is also our most popular dual tone siren. Rated at 122 dB, the Cat. No. EWS-V6 is an omni-directional siren which produces continuous 360° coverage, making it a superior alternative to a rotating siren. The Cat. No. EWS-V9 is a battery powered version of the EWS-V6. Edwards Signaling EWS-V9 includes a motor starter, charging system and battery box. The EWS-V6 is available in either single or three phase power. Both the EWS-V6 and EWS-V9 are dual tone sirens, 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.
