Early Warning Signal (EWS) 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. Featuring continuous duty motors, EWS Series sirens offer users a wide variety of early warning signaling solutions to fit virtually any application, large scale or mid-sized. Sirens range from the single-tone compact EWS-V1 models, rates at 107 dB, for large industrial facilities to the single-tone EWS-V3 units featuring projectors in an 8-horn, equal length, single-row configuration rated at 112 and 118 dB. All exposed siren components are made of zinc-plated, steel construction that is powder-coated for the most durable finish available. Fan and housing in each model are both made of non-corrosive cast aluminum.
