2/4 Wired Photoelectric Photoelectronic Smoke Detector

Product Description

Intoduction:
This photoelectric smoke detector detects 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 exteral 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. The photoelectric smoke detector in accordance with the networking approach is divied into 2-wire and 4-wire photoelectric smoke alarm.
