干粉滅火系統，由干粉供應源通過輸送管道連接到固定的噴嘴上，通過噴嘴噴放干粉的滅火系統。下面
川消小編為您講解下干粉滅火系統組件設置以及要求事項吧。
The powder extinguishing system is a fire extinguishing system that connects a dry powder supply source to a fixed nozzle through a conveying pipeline, and sprays dry powder through the nozzle. Below, the editor of Chuanxiao will explain to you the component settings and safety requirements of the dry powder fire extinguishing system.

（2）噴頭的單孔直徑應大于或等于6mm。
(2) The single hole diameter of the nozzle should be greater than or equal to 6mm.
干粉滅火系統使用要求
Safety requirements for the use of dry powder fire extinguishing systems
1.防護區內及入口處應設火災聲光警報器，防護區入口處應設置干粉滅火劑噴放指示門燈及干粉滅火系統性標志牌。
1. Fire sound and light alarms should be installed inside and at the entrance of the protection zone, and dry powder fire extinguishing agent spraying indicator door lights and permanent signs of the dry powder fire extinguishing system should be installed at the entrance of the protection zone.
2.防護區的走道和出口，必須保證人員能在30s內疏散。
2. The walkways and exits of the protective zone must ensure that personnel can safely evacuate within 30 seconds.
3.防護區的門應向疏散方向開啟，并應自行關閉的功能。
3. The door of the protective zone should open in the direction of evacuation and have the function of self closing.
4.防護區入口處應裝設自動、手動轉換開關。轉換開關安裝高度宜使中心位置距地面1.5m。
4. Automatic and manual transfer switches should be installed at the entrance of the protection zone. The installation height of the transfer switch should be such that the center position is 1.5m above the ground.
