Product Details

The item  is photoelectric smoke detector, detects the smoke by a couple of infrared  diodes. The principle of detecting is granule in the smoke can reflect infrared  light. Infrared diodes are placed in the special chamber. The chamber can  shield external light, but doesn't 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.
