關于氣體滅火系統的工作動作順序，很多用戶可能有些不是很清楚，今天
川消小編給大家梳理一下各種部件的動作順序，以便大家能夠更深刻的理解氣體滅火系統的工作原理。
Many users may not be very clear about the operation sequence of the gas fire extinguishing system. Today, Chuanxiao Xiaobian will sort out the operation sequence of various components so that you can have a deeper understanding of the working principle of the gas fire extinguishing system.
一、氣體滅火系統啟動方式有三種：自動啟動、人工電氣啟動和機械應急操作。
1、 There are three startup modes of gas fire extinguishing system: automatic startup, manual electrical startup and mechanical emergency operation.
二、氣體滅火系統自動啟動分為有人防護區和無人防護區，具體動作拆分如下：
2、 The automatic startup of the gas fire extinguishing system is divided into the manned protection area and the unprotected area. The specific actions are divided as follows:
（一）有人防護區：
（1） Manned protection area:
1、發生火情，防護區內路探測器（多為感煙）發送信號氣體滅火控制器后，氣體滅火控制器啟動防護區內的火災聲光警報器，同時氣體滅火控制器向消防聯動控制器反饋報警信號。此時的聲光警報器會提示防護區內人員火情發生，可以進行確認火災或者緊急逃生，但并不會啟動氣體滅火裝置；
1. In case of fire, after the first detector (mostly smoke detector) in the protection area sends a signal to the gas fire extinguishing controller, the gas fire extinguishing controller starts the fire audible and visual alarm in the protection area, and the gas fire extinguishing controller feeds back the alarm signal to the fire linkage controller. At this time, the audible and visual alarm will prompt the personnel in the protection area that there is a fire, which can confirm the fire or emergency escape, but will not start the gas fire extinguishing device;
2、若此時無人干預，火情擴大，第二路探測器（多為感溫）感應火災之后，防護區外的聲光警報器立刻響起，且此時已經可以確定火災確實發生了，那么氣體滅火系統準備啟動，系統進入30s延時階段，在延時階段，人員進行繼續疏散，并且系統會為氣體噴放作一些準備工作比如：
2. If no one intervenes at this time, the fire expands, and the sound and light alarm outside the protection area rings immediately after the second detector (mostly temperature sensitive) senses the fire, and it can be determined that the fire has indeed occurred, then the gas fire extinguishing system is ready to start, and the system enters the 30s delay stage. In the delay stage, people continue to evacuate, and the system will make some preparations for the gas discharge, such as:
1）關閉防護區域的送（排）風機及送（排）風閥門：
1) Close the air supply (exhaust) fan and air supply (exhaust) valve in the protection area:
2）停止通風和空氣調節系統及關閉設置在該防護區域的電動防火閥；
2) Stop the ventilation and air conditioning system and close the electric fire damper set in the protection area;
3）聯動控制防護區域開口封閉裝置的啟動，包括關閉防護區域的門、窗；
3) Linkage control the opening closing device of the protection area to start, including closing the doors and windows of the protection area;
3、經過30s的準備階段，該關閉的關閉，人員該疏散的疏散，那么接下來系統控制氣體進行噴放實施滅火。
3. After 30 s of preparation, if the shutdown is closed and the evacuation is completed, then the system controls the gas to spray and extinguish the fire.
（二）無人防護區
（2） Unprotected area
作為無人防護區來說，相對“有人防護區”控制就不需要考慮人員疏散的過程，因此在防護區內路探測器信號感應到火災之后，就會立刻執行關閥、關門、關風機的動作指令，當第二路探測器探測到火災之后，就立刻執行開啟選擇閥等后續操作。
As an unprotected area, the control of "manned protection area" does not need to consider the process of personnel evacuation. Therefore, after the first detector signal in the protection area senses a fire, it will immediately execute the action instructions of closing the valve, closing the door and closing the fan. When the second detector detects a fire, it will immediately execute the follow-up operations such as opening the selector valve.
二、手動啟動
2、 Manual start
手動緊急啟動可以通過兩種方式實現，一種是防護區外的“緊急啟動”按鈕啟動，另一種可以通過氣體滅火控制器上的手動控制按鈕，控制啟動。在該狀態下，探測器發出火災信號，控制主機啟動室內、外聲光報警器，通知火災發生，但并不啟動滅火系統。此時按下防護區外或控制器上的“緊急啟動”按鈕，可以啟動滅火系統，啟動滅火系統釋放滅火劑，實施滅火。
Manual emergency start can be realized in two ways, one is by pressing the "emergency start" button outside the protection area, and the other is by pressing the manual control button on the gas fire extinguishing controller. In this state, the detector sends a fire signal, and the control host starts the indoor and outdoor audible and visual alarms to notify the fire, but does not start the fire extinguishing system. At this time, press the "emergency start" button outside the protection area or on the controller to start the fire extinguishing system, start the fire extinguishing system to release the extinguishing agent and put out the fire.
三、機械應急手動啟動
3、 Mechanical emergency manual start
用于火災報警控制系統失效時，當自動和手動緊急啟動均失效時，當值守人員判斷為火災時，應立即通知現場所有人員撤離現場，在確定所有人員撤離現場后，可按以下步驟實施機械應急操作：
When the fire alarm control system fails, when the automatic and manual emergency starts fail, and when the on-duty personnel judge that there is a fire, they shall immediately notify all personnel on site to evacuate from the site. After all personnel are confirmed to evacuate from the site, the mechanical emergency operation can be carried out according to the following steps:
1）手動關閉聯動設備，并切斷電源；
1) Manually turn off the linkage equipment and cut off the power supply;
2）拔出相應防護區啟動瓶電磁驅動器上的“機械應急啟動保險銷”，按下機械應急啟動按鈕，電磁驅動器打開啟動瓶釋放啟動氣體，啟動氣體滅火系統。
2) Pull out the "mechanical emergency start safety pin" on the electromagnetic driver of the starting bottle in the corresponding protection area, press the mechanical emergency start button, and the electromagnetic driver will open the starting bottle to release the starting gas and start the gas fire extinguishing system.
注意：此方法預制式滅火系統操作有一定的危險性，需要通過培訓人員才可操作。
Note: the operation of prefabricated fire extinguishing system in this method has certain risks, which requires professional training personnel to operate.
