Description of Product

Photoelectric smoke detector detects the smoke by a couple of infrared diodes. The principle of detection is granule in the smoke can reflect infrared light. The infrared diodes are placed in the special chamber, the chamber reflects external light, but does not affect the smoke into it. While there is no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light, and the detector can give out alarm signal when the smoke attains the certain density. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal. The product in accordance with the networking approach is divided into 2-wire and 4-wire detectors.
