ISO 7240-8:2015规定了点式多传感器火灾探测器的要求、试验方法和性能标准，该探测器至少包含一个一氧化碳（CO）传感器和一个或多个热传感器，用于建筑物中安装的火灾探测和报警系统（见ISO 7240-1）。 对于其他类型的CO多传感器火灾探测器，或工作原理不同的CO和热量多传感器火灾探测器的测试，ISO 7240的本部分仅用于指导。ISO 7240本部分不包括针对特定风险开发的具有特殊特性的CO和热量多传感器火灾探测器。

ISO 7240-8:2015 specifies requirements, test methods, and performance criteria for point multi-sensor fire detectors that incorporate at least one carbon monoxide (CO) sensor in combination with 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 CO multi-sensor fire detectors, or CO and heat multi-sensor fire detectors working on different principles, this part of ISO 7240 is only to be used for guidance. CO and heat multi-sensor fire detectors with special characteristics and developed for specific risks are not covered by this part of ISO 7240.
