标准范围
ISO 7240-27:2009规定了多传感器点式火灾探测器的要求、试验方法和性能标准,这些探测器包括光学或电离烟雾传感器、用于感应一氧化碳(CO)的电化学电池,以及(可选)一个或多个热传感器,用于安装在建筑物中的火灾探测和报警系统(见ISO 7240-1)。对于使用不同原理的烟雾、一氧化碳和可选热传感器测试其他类型的火灾探测器,ISO 7240-27:2009仅可用于指导。ISO 7240-27:2009未涵盖使用烟雾、一氧化碳和(可选)热传感器的火灾探测器,这些探测器具有特殊特性,并针对特定风险开发。
ISO 7240-27:2009 specifies requirements, test methods and performance criteria for multi-sensor point-type fire detectors that incorporate an optical or ionization smoke sensor, an electro-chemical cell for sensing carbon monoxide (CO) and, optionally, one or more heat sensors, for use in fire detection and alarm systems installed in buildings (see ISO 7240-1).For the testing of other types of fire detectors using smoke, CO and, optionally, heat sensors working on different principles, ISO 7240-27:2009 can be used only for guidance. Fire detectors using smoke, CO and, optionally, heat sensors which have special characteristics and which have been developed for specific risks are not covered by ISO 7240-27:2009.
