    Đặc điểm nổi bật:

    The 800 series are 2-wire conventional low profile plug-in detectors designed to meet the performance criteria designated by
    UL. It is a low cost and high reliability series. A LED will be latched on to locally indicate alarm. The in (-) and out (-) terminals
    are short-circuited inside the detectors. When the detector is mounted , it will continue the wire to the next device or EOL
    resistor. When it is removed, the wire will be open for wiring supervision.
