Product Introduction The non-pressure-storage ultra-fine dry powder fire extinguishing device is a new generation of high-efficiency and environmentally friendly fire-fighting products. The ABC ultra-fine dry powder fire extinguishing agent filled with is non-toxic, harmless, non-corrosive to the protection, non-irritating to human skin and respiratory tract, and fires quickly. , High efficiency, is an ideal substitute for halon fire extinguishing agent. Earth fire non-pressure storage type ultra-fine dry powder fire extinguishing device has simple structure, reliable performance, convenient installation and maintenance. It can be used for full-submerged fire extinguishing in enclosed spaces and local application fire extinguishing in open places. It is ideal for fire fighting in industrial and mining, schools, institutions and other departments equipment. Working principle Electric control start mode: connect the electric starter on the fire extinguishing device with the fire alarm control system, and the fire extinguishing device can be started electronically. 1) Electronically controlled automatic start. The fire extinguishing device is under automatic control when the fire extinguishing controller is set to the "automatic" position. When a fire occurs in the protected area, the fire extinguishing controller will automatically start the fire extinguishing device to spray fire extinguishing agent to extinguish the fire after it has determined that the fire has indeed occurred. 2) Electronically controlled manual start When the fire extinguishing controller is set to the "manual" position, the fire extinguishing device is in manual control state. When a fire occurs in the protection area, manually press the start button on the fire extinguishing controller or the manual control panel to start the fire extinguishing device to spray fire extinguishing agent to implement fire extinguishing. 3) Emergency stop After the fire alarm controller sends out the start command, or manually presses the start button, within 30s of the set delay time, if personnel find that there is no fire, they can press the emergency stop button and the fire device stops start up.
