Siren Design Characteristics

Models STi-1600 & STi-3200 produce 115 and 126 decibels respectively, tested in free field non-reflective measurement environments with repeatable results. Applications Include omni-directional or quadrant configurations for 90*-360° coverage patterns. The color-impregnated fiberglass siren horns endure severe weather conditions, are maintenance free, and will not rust or require painting. The Electronic Controls have a self-contained, regulated battery charging system that assures full siren operation during AC outages. The control charging unit requires a nominal 120 VAC 50/60Hz power with 5 amp service.
