Alarm Sirens and Signalers

Loud Alarm Signalers - Optical and Acoustic. Alarm signalers, commonly known as sirens, are an essential element of any alarm system. Their task is to immediately alert the surroundings to a detected threat (e.g., a burglary) through a very loud sound signal (acoustic) and intense light signals (optical). An effective signaler fulfills two functions: it informs the owner and neighbors of the event and acts as a deterrent to the intruder, forcing them to flee.
