Beida Jade Bird Point fire detectors photoelectric smoke detector JTY-GD-JBF-3100 built-in microprocessor CPU. Probe collected data for their own store and judge the Gulf smoke, and have self-diagnostic function;? Adjustable sensitivity. Enables users of different sensitivity to detect environmental requirements;? Pollution automatic compensation. According to their degree of pollution zero drift, minimizing false positives;? Output concentration of smoke. The controller can always see the scene through the smoke concentration curve;? Bay alarm button for a wide range of white smoke or black smoke produced by the burning of different materials can respond after;? Strong anti-jamming capability. Through a special circuit design makes external electromagnetic radiation interference, the impact of external light (light) to minimize interference;? For early fire detection space inside the building;? Bay alarm smoke alarm through the controller, and the linkage with the fire fighting equipment ;? detectors meet the national standard GB4715-1993 "Point-type smoke detectors technical requirements and test methods", its application designed to comply with the national standard GB50116-1998 "automatic fire alarm system design specifications"; Gulf GST-LD-8300 Input Module This module shape and structure of GST-LD-8319 Input Module same mounting method which is the same: Z1, Z2: I control signal and the second terminal connected to the bus, G: and passive devices normally open contacts ( Equipment action closes the alarm type) connection; also available through electronic encoder settings for NC input module has a normally open dry contact with field device connection method. Module input setting parameter is set to normally open inspection lines. Gulf controller | the four Gulf | Ultra-fire offered by Dongguan Nan ultra fire equipment operators.
