不要进入该地区\
In protected area, sign board shall be installed to state “when alarm for emission of FM200 gas is raised, people shall evacuate from the area immediately”六. 使用事项 OPERATION CONDITION
1. 本工程的灭火系统启动操作方式分为自动、手动、机械应急三种. Gas extinguishing system operation include automatic, manual and mechanical for emergency.
1）自动：即自动探测报警,发出火警信号.自动启动灭火系统进行灭
火.
Automatic: By automatic detection of fire, release of fire alarm, extinguish the fire automatically.
2）手动：即自动探测报警,发出火警信号.经人工电气手动启动灭火
系统执行灭火, 上述自动工况的电气手动工况的转换在灭火控制盘上实现,不论灭火控制按钮处于哪一种 工况,当人为发出火警时,都可以使用该火警区的手动控制盒,电气手动启动灭火系统进 行灭火,手动控制盒的另一项功能是它可以在灭火系统动作前,撤消灭火控制盘发出的本 区域的指令,以防止不需由灭火系统进行灭火时启动灭火系统.
Manual: By automatic detection of fire, manual operate the gas release mechanism for fire fighting. Under such condition, irrespective to the mode of the push button, the gas release control could be manually operated.
Another function of the Manual operation is to abort the control instruction locally before release of gas to prohibit unnecessary fire fighting operation.3）机械应急 Mechanical emergency operation
