标准摘要
[中文适用范围]： 本文件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。这些探测器集烟雾传感器、一氧化碳（CO）传感器于一体，并可选配一个或多个热传感器，用于建筑物中的火灾探测和报警系统。本文件不适用于具有特殊特性且针对特定风险开发的使用烟雾、CO 和/或热传感器的火灾探测器。对于基于不同原理工作的其他类型的使用烟雾、CO 和/或热传感器的火灾探测器的测试，本文件仅供参考。 [外文原描述]： This document specifies requirements, test methods and performance criteria for multi-sensor point fire detectors that incorporate a smoke sensor, a carbon monoxide (CO) sensor and, optionally, one or more heat sensors, for use in fire detection and alarm systems installed in buildings (see ISO 7240-1). This document is not applicable to fire detectors using smoke, CO and, optionally heat sensors, which have special characteristics, and which have been developed for specific risks. For the testing of other types of fire detectors using smoke, CO and, optionally, heat sensors working on different principles, this document can therefore be used only for guidance.
