Edwards Warning Siren
127 dB
Edwards is a registered trademark of UTC Fire & Security

Featuring the industry's largest drive motor, this 8 HP, battery powered rotating siren delivers all the features one expects from a premium warning device.

Utilizing a 460 Hz tone, the EWS-11's low pitch is designed to penetrate structures and obstacles, making the warning area more complete. The EWS-11 features the same bullet-proof design and construction as other Edwards sirens. The EWS-11 uses top of the line, maintenance free rotating mechanisms and hand rolled, custom formed projectors.

All exposed siren components are of heavy gauge aluminum alloy and electro-plated, galvanized steel construction, which are "powder coated" for the most durable finish available.

The entire mass of the siren is centered over the pole so no stabilizing wires are required. Total shipping weight of the EWS-11 is 385 lbs. (174.6 kg).
