UL Intelligent Photoelectric Smoke Detector

I-9102(UL) detector can form fire alarm system connecting with fire alarm control panel. The detector illuminates indicators to indicate fire alarm status and transmits the fire signal to the control panel. Using infrared scattering technology, the detector receives very weak infrared light under normal smokeless condition. If smoke particles enter the chamber, the received ligt signal will increase by scattering. When smoke density reaches a pre-set level, the detector will alarm out. In order to reduce interference and power consumption, the emitting circuit works in pulse mode to prolong the life of IR LED.
