（1）根據所使用的噴頭類型，可分為閉式系統和開式系統。
(1) According to the type of nozzle used, it can be divided into closed system and open system.
閉式噴頭，有釋放機構，平時噴頭出水口用釋放機構封閉住，滅火時，釋放機構自動脫落，開啟噴頭噴水。噴頭一旦開放，便不能自動恢復原狀。而開式噴頭沒有釋放機構，噴水口是敞開的，管路中是自由空氣，噴頭可重復使用。
Closed nozzle, with a release mechanism. The outlet of the nozzle is usually sealed with a release mechanism. When extinguishing a fire, the release mechanism automatically comes off and the nozzle is turned on to spray water. Once the nozzle is opened, it cannot automatically return to its original state. The open nozzle does not have a release mechanism, the spray nozzle is open, and there is free air in the pipeline. The nozzle can be reused.
（2）根據系統的用途和配置狀況，可分為濕式系統、干式系統、預作用系統、防護冷卻系統、雨淋系統、水幕系統（防火分隔水幕和防護冷卻水幕）、自動噴水-泡沫聯用系統等。
(2) According to the purpose and configuration of the system, it can be divided into wet system, dry system, pre action system, protective cooling system, deluge system, water curtain system (fire separation water curtain and protective cooling water curtain), automatic sprinkler foam combined system, etc.
四、濕式自動噴水滅火系統
4、 Wet automatic sprinkler fire extinguishing system
（1）組成：由閉式噴頭、濕式報警閥組、水流指示器或壓力開關、供水與配水管道以及供水設施等組成。
(1) Composition: It consists of a closed nozzle, a wet alarm valve group, a water flow indicator or pressure switch, water supply and distribution pipelines, and water supply facilities.
（2）定義：準工作狀態時配水管道內充滿用于啟動系統的有壓水的閉式系統。
(2) Definition: A closed system in which the water distribution pipeline is filled with pressurized water for starting the system in a quasi working state.
特點：采用閉式噴頭的滅火系統；準工作狀態下管網中充滿有壓水；當噴頭保護范圍內發生火災，噴頭熱敏元件受熱達到或超過公稱動作溫度時，熱敏元件動作（熔化、破碎），從而噴頭開啟，出水滅火，同時系統自動啟動。
Features: Adopting a closed nozzle fire extinguishing system; Under quasi working conditions, the pipeline network is filled with pressurized water; When a fire occurs within the protection range of the nozzle, and the thermal element of the nozzle is heated to or exceeds the nominal operating temperature, the thermal element will act (melt or break), causing the nozzle to open, water to extinguish the fire, and the system will automatically start.
（3）適用范圍
(3) Applicable scope
設置早期抑制快速響應噴頭的倉庫及類似場所，環境溫度不低于4℃且不高于70℃的場所，應采用濕式系統。
Warehouses and similar places with early suppression and rapid response nozzles, and places with ambient temperatures not lower than 4 ℃ and not higher than 70 ℃, should use wet systems.
五、干式自動噴水滅火系統
5、 Dry automatic sprinkler fire extinguishing system
（1）組成：由閉式噴頭、干式報警閥組、水流指示器或壓力開關、供水與配水管道、充氣設備以及供水設施等組成。
(1) Composition: It consists of a closed nozzle, a dry alarm valve group, a water flow indicator or pressure switch, water supply and distribution pipelines, inflation equipment, and water supply facilities.
（2）定義：準工作狀態時配水管道內充滿用于啟動系統的有壓氣體的閉式系統。
(2) Definition: A closed system in which the water distribution pipeline is filled with pressurized gas used to start the system in a quasi working state.
特點：采用閉式噴頭的滅火系統；準工作狀態時配水管道中充滿有壓氣體；當噴頭保護范圍內發生火災，噴頭熱敏元件受熱達到或超過公稱動作溫度時，熱敏元件動作（熔化、破碎），從而噴頭開啟，系統開始排氣充水，啟動方式類似濕式系統。
Features: Adopting a closed nozzle fire extinguishing system; When in quasi working condition, the water distribution pipeline is filled with pressurized gas; When a fire occurs within the protection range of the nozzle, and the thermal sensitive components of the nozzle are heated to or exceed the nominal operating temperature, the thermal sensitive components will act (melt or break), causing the nozzle to open, and the system will begin to exhaust and fill with water. The starting method is similar to a wet system.
（3）適用范圍
(3) Applicable scope
環境溫度低于4℃或高于70℃的場所，應采用干式系統。
Places with ambient temperatures below 4 ℃ or above 70 ℃ should adopt dry systems.
六、預作用自動噴水滅火系統
6、 Pre action automatic sprinkler fire extinguishing system
（1）組成：由閉式噴頭、預作用裝置、水流報警裝置、供水與配水管道、充氣設備和供水設施等組成。
(1) Composition: It consists of a closed nozzle, pre action device, water flow alarm device, water supply and distribution pipeline, inflation equipment, and water supply facilities.
（2）定義：準工作狀態時配水管道內不充水，發生火災時由火災自動報警系統、充氣管道上的壓力開關聯鎖控制預作用裝置和啟動消防水泵，向配水管道供水的閉式系統。
(2) Definition: A closed system in which the water distribution pipeline is not filled with water in the quasi working state. In the event of a fire, the fire automatic alarm system, the pressure switch interlocking control pre action device on the inflation pipeline, and the start of the fire water pump are used to supply water to the water distribution pipeline.
特點：采用閉式噴頭的滅火系統；準工作狀態時配水管道中不充水；當發生火災時，由火災自動報警系統和充氣管道上的壓力開關連鎖控制預作用裝置和啟動消防水泵，并轉化為濕式系統;與濕式系統、干式系統的不同之處在于，系統采用預作用裝置，并配套設置火災自動報警系統。
Features: Adopting a closed nozzle fire extinguishing system; When in quasi working condition, the water distribution pipeline is not filled with water; When a fire occurs, the fire automatic alarm system and the pressure switch on the inflation pipeline interlock to control the pre action device and start the fire water pump, and convert it into a wet system; The difference between wet and dry systems is that the system adopts a pre action device and is equipped with a fire automatic alarm system.
（3）適用范圍
