Intelligent Addressable Optical Detector

I-9102 Intelligent Photoelectric Smoke Detector is an addressable fire alarm device cooperating with GST intelligent fire alarm control panels to build a fire detection system. It shows fire alarm by LEDindicators and transmits the fire signal to the controlpanel. Using infrared scattering technology, the smoke density can be detected. The detector receives veryweak infrared light under normal smokeless condition. If smoke particles enter the chamber, the received light signal will increase by scattering. When smoke density reaches a pre-set level, the detector will alarm out. Inorder to reduce interference and power consumption,the emitting circuit works in pulse mode to prolong thelife of IR LED.
