14、。如果是用一套灭火剂贮存装置单独保护一个防护区，就称为单元独立系统。2.1 System Configuration: CO2 fire extinguishing systems are applicable to total flooding systems and local flooding systems, and divided into combined distribution systems and unit-independent systems by configuration method. A combined distribution system refers t

If one gas extinguishing agent storage device is used for a separate protection area only, it is called unit-independent system.2

16、.2控制方式：2.2 Control Modes:本系统主要有自动、手动、机械应急手动和紧急启动/停止四种控制方式，控制过程参见控制流程图: This system is provided with auto mode, manual mode, mechanically emergency manual mode and emergency start/stop mode.

18、up Fire ExtinguishingDischarge DisplayElectrically Manual ModeProtection Area for Evacuation（1）自动控制方式：灭火控制系统可以配置感烟火灾探测器、感温火灾探测器、火焰探测器或其它种类探测器，控制器本身有“自动”和“手动”控制方式选择功能，当选择成“自动”方式时，控制器处于自动控制状态。(1) Automatic Control Mode: The fire control system can be equipped with smoke fire detectors, heat fire detec

19、tors, flame detectors, or other types of detectors, and the controller itself has “automatic” and “manual” control modes for selection. When in “auto” mode, the controller is in automatic control status.自动控制方式时，当同一个保护区内只有一种探测器检测到火灾迹象时，控制系统发出火警声和光信号，通知有异常情况发生，而不启动灭火装置释放灭火剂。如工作人员确认火灾确实发生，确需启动灭火装置灭火时，可

20、按下“紧急启动按钮”，即可启动灭火装置实施灭火；当有两种探测器同时检测到火灾迹象时，控制系统发出声音信号，通知有火灾发生，有关人员应立即撤离现场，并发出联动指令，关闭风机、防火阀等联动设备，经过030s延时后，控制器发出灭火信号，电动开启氮气驱动装置，驱动气体会打开对应的二氧化碳灭火瓶组实施灭火；如在控制器延时过程中发现并不需要启动灭火装置，此时可按下保护区外的或控制器操作面板上的“紧急停止按扭”，即可终止控制灭火指令的发出。Under the automatic control mode, when only one type of detector detects fire in a pr

21、otection area, the control system will send out fire alarm sound and a light signal notifying unusual circumstance, without initiating the extinguishing agent release device. If the staff confirm a fire does occur which requires the fire extinguishing device, please press the “emergency start button

22、” to start the fire extinguishing device; when there are two types of detectors simultaneously detect signs of fire, the control system will send out a sound signal notifying the fire, and relevant personnel should immediately evacuate from the site and issue an linkage command to turn off fans, fir

23、e dampers and other devices linked, and after a time delay of 0 30s, the controller will send out a fire extinguishing signal, upon which, the motor will start the nitrogen driving device to use the driving gas to open CO2 extinguishing agent bottle group; if, during the time delay, the fire extingu

24、ishing is found not needed, please press the “emergency stop button” outside the protection area or on the controller panel to stop the command.（2）手动控制方式：当选择成“手动”控制方式时，灭火控制器处于手动控制状态。无论那类探测器检测到火情或误报警，控制器只发出火灾声光报警信号，而不启动灭火装置，需经人员观察后确认火灾已发生，方可按下保护区外或控制器操作面板上的“紧急启动按钮”，即可启动灭火装置实施灭火。无论装置处于自动或手动状态，按下任何紧急启动

25、按扭，都可启动灭火装置实施灭火。同时控制器立即进入灭火报警状态。(2) Manual Control Mode: Under the manual control mode, the fire controller will be manual operated. No mater which type of detector detects a fire or makes any false alarm, the controller will send out an acousto-optic fire alarm signal only, rather than starting the

26、 fire extinguishing device, and do not pressure the “emergency start button” outside the protection area or on the controller panel to implement fire extinguishing until the fire is confirmed by the staff. Regardless of the control mode, the fire extinguishing device can be initiated by pressing any

27、 emergency start button, and the controller will enter into the fire alarm status immediately.（3）应急机械启动工作方式：用于控制器失效时，当职守人员确认火灾已经发生，应立即通知现场所有人员撤离现场，并停止一切有可能影响灭火效果的设备，在确定所有人员撤离现场后，方可按以下步骤实施应急机械启动：拔掉氮气驱动装置电磁铁手动柄上的保险销，用力向下拍击手动柄，氮气即可释放，氮气会按事先设置好的路径打开灭火剂储存瓶组是防灭火剂。(3) Emergency Mechanical Mode: This mode i

When the person on duty confirms a fire has occurred, he/she shall immediately notify all personnel on site to evacuate and turn off all equipment that may affect fire extinguishing. After all personnel evacuate from the site, take the following steps to make an

29、emergency mechanical start: Pull the safety pin out from the electromagnet manual handle of the nitrogen driving device, and then firmly slap down the manual handle to release the nitrogen which will open the extinguishing agent storage bottles to release extinguishing agent as preset.三、系统主要部件III.
