FZX-ACT3 / 1.2-DD, FZX-ACT4 / 1.2-DD, FZX-ACT5 / 1.2-DD, FZX-ACT6 / 1.2-DD, FZX-ACT8 / 1.2-DD, FZX-ACT10 / 1.2-DD Hanging dry powder fire extinguishing device is a new generation of high-efficiency and environmental protection fire protection products produced by Huizhou Huiyang Dadi Fire Fighting Equipment Co., Ltd. The filled ABC superfine dry powder fire extinguishing agent is non-toxic, harmless, non-corrosive to the protection, non-irritating to human skin and respiratory tract, fast fire extinguishing and high efficiency, and is an ideal substitute for halon fire extinguishing agent. The earth fire storage pressure type superfine dry powder fire extinguishing device has a simple structure, reliable performance, and convenient installation and maintenance. It can be used for fully submerged fire suppression in closed spaces, or for local application in open places. It is an ideal fire-fighting equipment for industrial, mining, schools, and other departments.
When a fire occurs in the protected area, the thermal line power supply dual-control pressure storage ultra-fine dry powder fire extinguishing device is automatically started by the external thermal line combustion or the worker manually presses the emergency button to start the electrical signal. With the storage pressure, the ultra-fine dry powder is suspended. The pressure inside the shell increases rapidly, and the dry fire extinguishing powder breaks through the sealed aluminum baffle under the pressure of the gas. It quickly sprays into the protection area and spreads around, forming a fully submerged fire extinguishing state, or a local fire extinguishing state. Extinguished under physical and chemical effects.
主要由贮粉罐、喷头、压力指示器、感温玻璃球（易熔合金）、吊环等组成。 Pressure storage hanging dry powder fire extinguishing device The fire extinguishing device is mainly composed of powder storage tank, sprinkler, pressure indicator, temperature-sensitive glass ball (fusible alloy), and hanging ring. See Figure 1
罐内充装ABC超细干粉灭火剂，驱动气体为氮气。 The tank of the storage pressure hanging dry powder fire extinguishing device is filled with ABC ultrafine dry powder fire extinguishing agent, and the driving gas is nitrogen.

： Earth fire non-storage type superfine dry powder fire extinguishing device is suitable for extinguishing fires of the following substances :
扑救 A 类火灾：如棉、木、麻、纸、橡胶、塑料、烟草等可燃固体火灾。 1. Fight Class A fires: such as cotton, wood, linen, paper, rubber, plastic, tobacco and other combustible solid fires.
扑救 B 类火灾：如原油、重油、柴油、汽油、有机溶剂等可燃液体、可熔化固体火灾。 2. Fight Class B fires: such as crude oil, heavy oil, diesel, gasoline, organic solvents and other flammable liquids and meltable solids.
扑救 C 类火灾 : 如煤气、天然气、乙炔等可燃气体火灾。 3. Fight Class C fires : such as gas, natural gas, acetylene and other combustible gas fires.
扑救 E 类火灾 : 如机房、变电站、电缆隧道、电缆井沟等场所带电设备火灾。 4. Extinguish Class E fires : fires in live equipment such as equipment rooms, substations, cable tunnels, cable trenches, etc.
Earth fire non-storage type superfine dry powder fire extinguishing device is not suitable for extinguishing the following fires:
硝酸纤维、炸药、氧化氮、氟等在无空气是仍能发生氧化反应的化学物质与氧化剂； 1. Nitrogen fibers, explosives, nitrogen oxides, fluorine, etc. are chemical substances and oxidants that can still undergo oxidation reactions in the absence of air;
钾、钠、镁、钛、锆等活泼金属及其氢化物。 2. Potassium, sodium, magnesium, titanium, zirconium and other active metals and their hydrides.
Electrically controlled starting method: The electronically controlled starter on the fire extinguishing device is connected with the fire alarm control system, and the fire extinguishing device can be started electronically. See Figures 1 to 3
1) Electric control automatic start When the fire extinguishing controller is set to the "automatic" position, the fire extinguishing device is in the automatic control state. When a fire breaks out in the protected area, after the fire extinguishing controller determines that a fire does occur, it automatically starts the fire extinguishing device to spray fire extinguishing agent to extinguish the fire.
2) Electric control manual start When the fire extinguishing controller is set to the "manual" position, the fire extinguishing device is in the manual control state. When a fire occurs in the protected area, manually press the start button on the fire extinguishing controller or manual control panel to start the fire extinguishing device to spray the fire extinguishing agent and extinguish the fire.
3) Emergency stop After the fire alarm controller issues a start command, or after manually pressing the start button, within 30s of the set delay, if a person finds that there is no fire, they can press the emergency stop button to stop the fire device. start up.
