Product introduction:
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 allains 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

Product featurs:
*Strong adaptability for circumstance
