Smoke Detector Alarm Accessories

Smoke Detector Alarm Accessories Description

The Smoke Detector Alarm Accessories work on the principle that infrared scatters in the smoke to probe the smoke which is generated by the incomplete combustion at the initial stage of the fire. It consists of a photoelectric system, signal processing identification circuit and alarm circuit. The infrared scatter on the surface of the smoke when the smoke enters the darkroom of the detector, then the photoelectric diode receives the scattered light and generates the photoelectric signal current. The photoelectric signal generates the alarm signal after being processed by the identification circuit, accordingly the purpose of alarming is achieved.

Every fire alarm we sell comes complete with a 5year manufacturer's warranty, provided it is serviced in accordance with the requirements of BS 5306 part 3. This guarantee does not cover defects caused by accident, misuse or neglect.
