ZDMP0.25/5S This fire extinguishing device uses a red/ultraviolet composite detector as the front-end detection equipment, which can effectively detect the flame signal. Once the detector detects a fire, it immediately outputs a control signal to alarm, start the water pump, open the solenoid valve, and the nozzle is in the water flow. Under the action of torsion force, water spraying is carried out in 360 degrees. After the fire is extinguished, the device automatically stops water spraying. If there is a new fire source, the fire extinguishing device will repeat the above process.
