GST DC-M9102 photoelectric smoke detector

• Make: GST
• Model code: DC-M9102
• Type: Smoke

GST DC-M9102 is a conventional photoelectric smoke detector with built-in microprocessor. The detector will send signal to a fire alarm control panel (FACP) or addressable zone monitor unit by means of current changes. The detector indicates its fire condition by turning on fire LED and keeping the LED on until it is reset. Using infrared scattering technology, with an innovative chamber, 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 certain amount, the detector will give alarm signals. In order to reduce interference and power consumption, the emitting circuit works in pulse mode to prolong the life of IR LED.
