Fire alarm Conventional Photoelectric Smoke Sensor Wired Smoke Detector
2 Wired / 4 Wired Conventional Network Photoelectric Smoke Detector Fire Alarm
Product introduction
This product named Photoelectric smoke detector (hereinafter called 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 received very weak infrared light.When the smoke detector 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.
