Conventional fire alarm system combined smoke and heat detector

 

Features of product

Photoelectric Smoke detector,4-wire,network by Relay

This product named Photoelectric smoke and heat detector (hereinafter called detector)detects the smoke by a couple of
infrared diodes,includes a built-in+57 ± 2.7 heat detector.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.The product in accordance with the networking  approach is divided into 2-wire and 4-wire detectors.
