Original Press Release:

Edwards' Omni-Directional, Outdoor Public Warning Sirens Project Clear, Uniform, Full-Decibel Output in All Directions

EWS Series provides instantaneous warning for greater safety

CHESHIRE, Conn., Dec. 9, 2002 - Edwards's new, omni-directional, public warning sirens project a clear and powerful decibel level in all directions simultaneously. This 360°, omni-directional advantage means that emergency warnings are communicated for greater safety, avoiding the distorting "peaking-and-ebbing" effect associated with a rotating siren system.

Edwards' outdoor EWS Series sirens, featuring continuous duty motors, offer customers a wide variety of early warning signaling solutions to fit virtually any application, large scale or mid-sized. The Series ranges from the single-tone compact EWS-V1 models, rated at 107 dB, for large industrial facilities or small communities, to the single-tone EWS-V3 units featuring projectors in an 8-horn, equal length, single-row configuration, rated at 112 and 118 dB, for warning over long distances. Dual-tone models range from the EWS-V4 Series, rated at 115 dB, to the 125 dB EWS-V8-3, the largest omni-directional siren in existence. Decibel ratings for wide area signals are calculated at 100 ft. or 30.5 m.

All exposed siren components are made of zinc-plated, steel construction that is powder-coated for the most durable finish available. The fan and housing in each model are both made of non-corrosive cast aluminum.
