JK761 gas fire extinguishing controller is mainly used for various gas fire extinguishing systems with or without pipeline networks, such as carbon dioxide, heptafluoropropane, trifluoromethane, 1G-541, SDE, etc. It can be connected to address coded smoke and temperature fire detectors, and can also be connected to non coded fire detectors through relay modules for fire alarm; It can be equipped with a bus based manual/automatic switch, gas release alarm, gas start/stop button, and control and detect the status of gas fire extinguishing equipment and related alarm devices through the gas spray control and spray feedback terminals on the internal circuit board; Control selection valves, fire-resistant doors and windows, etc. through modules. It can be widely used in computer rooms, data rooms, distribution rooms, substations, communication stations and other places.
