Smoke detector relay output DC power alarm system
DC5V 4 wires smoke detector with relay output
Product Description:

This product named 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 accumulates to the certain density. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pules signal. The product in accordance with the networking approach is divided into 2 -wire and 4-wire detectors.
