ZDMS0.6/5S-ZSS25A/B automatic jet fire extinguishing device combines infrared / ultraviolet sensing technology, signal processing technology, communication control technology, computer technology and mechanical transmission technology organically. Can automatically monitor the fire within the protection range all the time. In the event of a fire, the device starts immediately, carries on the horizontal and vertical two-dimensional scanning of the fire source, determines the two orientations of the fire source, the central controller issues the instruction, sends out the fire alarm signal, starts the pump at the same time, opens the valve, The fire extinguishing device aims at the fire source to extinguish the water. After the fire source is extinguished, the central controller issues instructions to stop the water injection. If there is a new fire source, the fire extinguishing device will repeat the above process and return to the monitoring state after all the fire sources have been extinguished. The water jet form of this device is cylindrical water jet, long range, wide protection range and very strong fire extinguishing ability. Suitable for large shopping malls, gymnasiums, theatres, convention and exhibition centers, airports, railway stations, warehouses, factories, clubs and other large and tall space places. In addition, according to the actual engineering needs, combined with the field image transmission technology, the fire extinguishing device can monitor the protection site and manually control the fire situation.
