标准范围

ISO 7240-1:2005提供了一套通用指南和定义，用于描述ISO 7240其他部分中的火灾探测和报警系统设备、测试和要求。火灾探测和报警系统的组件如图1所示。图1中的C项可以用紧急情况下的音响系统代替，其部件如图2所示。火灾探测器可以是自给自足的:这些装置在一个外壳内包含探测火灾和发出声音警报所需的所有组件，可能除了能源。符合ISO 12239且未连接到控制和指示设备的互连烟雾报警器不会构成ISO 7240-1:2005中定义的火灾探测和报警系统。

ISO 7240-1:2005 provides a set of general guidelines and definitions to be used in describing the fire detection and alarm system equipment, tests and requirements in the other parts of ISO 7240.The components that a fire detection and alarm system can have are shown in Figure 1. Item C of Figure 1 can be replaced by a sound system for emergency purposes, the components of which are shown in Figure 2.Fire detectors can be self-contained: these are devices containing within one housing all the components, except possibly the energy source, necessary for detection of fire and giving an audible alarm.Inter-connected smoke alarms complying with ISO 12239 and not connected to control and indicating equipment do not form a fire detection and alarm system as defined in ISO 7240-1:2005.
