It operates on a dual-wire system, which allows for simultaneous transmission of power and signal. The horn component produces a loud sound to alert individuals in the vicinity, while the strobe light provides a bright, flashing visual cue. The product is compatible with standard fire alarm control panels (FACPs) and can be easily installed on walls or ceilings. Its robust construction ensures durability and reliability under various environmental conditions.
