QD6000 type multi-point monitoring combustible gas detection alarm controller, used to detect flammable gas in the air or liquid vapor explosion within the lower limit of content, can take a number of detection probe, while multi-point centralized control. The system adopted microprocessor as control unit, high performance catalytic gas sensor as detection sensor, high sensitivity, fast response. When the combustible gas concentration in the environment reaches or exceeds the preset alarm value, the controller will alarm immediately , and driving the exhaust or other peripheral action, to prevent fire accidents and explosion,so that protect life, this system widely used in factories, oil depots, liquefied gas station, gas station, petrol station, spraying room etc. And other need fire and explosion place safety alarm.
