The Edwards 757-4A-T is a red temporal horn-strobe from the Integrity 757 Series, combining a field-selectable horn with a 75 candela xenon strobe for combined audible/visible fire alarm notification. The horn produces a temporal-three (T3) evacuation pattern or continuous tone, selectable in the field along with HIGH (98 dBA) or LOW (94 dBA) volume, and the strobe delivers a bright, consistent flash for visibility in large or noisy spaces.
