Descripton

A burglar alarm siren is a device designed to protect premises from break-ins and thefts. After the security system sensor is triggered, a siren is activated, which, by sound or light, draws the attention of neighbors to the guarded object and scares off intruders from the scene.

After the alarm control panel (central panel) sends an alarm signal received from the sensors to the siren, the light, sound or light and sound indication of the event turns on. The sound signal can be of different tones, with a power of up to 110 dB. The light alert often looks like a flashing beacon or flashing light. Some sirens are also equipped with tampers, as are many other security devices. The tamper is a switch that works and activates the siren if an intruder tries to remove the siren from its mounting or damage its case.
