    Characteristics

    • Detector has a monitoring LED that operates about every 16 seconds ( flash ) during standby status. When there is smoke, the detector will issue fire signal after 16 consecutive confirmations. (every 0.3 second) If any dust causes flashing or an intermittent signal, it will return to normal status after 32 confirmations.
    • The coating of terminal contacts meets the Rohs and provides better results on corrosion and conductive.
    • Each detector has added specific components that will effectively isolate interference from electromagnetic fields and lightening strike.
    • All detectors use high-density steel for the contacting plate material.
