Fire Projects has installed C-9102 Conventional Photoelectric Smoke Detector various sites which is non-addressable. Used together with end of line unit, it can connect with compatible control panels to process detection signals. C-9102 Conventional Photoelectric Smoke Detector supplied by Fire Projects shows fire alarm by LED indicators and transmits the fire signal to the control panel. Using infrared scattering technology, the smoke density can be detected. The detector receives very weak 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. In order to reduce interference and power consumption, the emitting circuit works in pulse mode to prolong the life of IR LED.
