Network-Wired Optical Smoke Detector

    Network-Wired Optical Smoke Detector
  
Introduce:
  This product named Photoelectric 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 don't affect the smoke into it. While have no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.   Main Feature:   1.Optical detection 2.Digital Smart program analysis technology 3.Ceiling mounted 4.User-friendly design and easy to wire 5.Manual test function 6.Automatic reset function         Specifications:
