火灾探测和警报系统. 第15部分: 利用烟雾和热量传感器的点型火灾探测器

[中文适用范围]： ISOO 7240 的这一部分规定了使用烟雾和热传感器的指针型火灾探测器的要求、测试方法和性能标准，在一个机械外壳中包含至少一个烟雾传感器和至少一个对热做出响应的其他传感器，其中信号（s） ）的烟雾传感器（Sj）与热传感器（S）的信号相结合。 ISO 7240本部分涵盖的探测器内的单个传感器的性能不足以符合ISO 7240的其他部分ISO 7240 单传感器探测器。 某些类型的探测器可能含有放射性物质。 各国对辐射防护的国家要求不同，因此未在本标准中规定。 但是，此类探测器应符合国家要求和符合经济合作与发展组织（OECD）D 核能机构（NEA）的建议，对于其他类型探测器或工作原理不同的探测器的测试，这部分风险，不IS907240 的本部分涵盖了。 [外文原描述]： ISO 7240-15:2014 specifies requirements, test methods, and performance criteria for point-type fire detectors using smoke and heat sensors, incorporating in one mechanical enclosure at least one smoke sensor and at least one other sensor which responds to heat, and in which the signal(s) of the smoke sensor(s) is (are) combined with the signal(s) of the heat sensor(s). The performance of a single sensor within the detector covered by ISO 7240-15:2014 cannot be sufficient for conformity to other parts of ISO 7240 for the single sensor detector. Certain types of detectors can contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not therefore specified in this standard. However, such detectors are expected to conform to the national requirements and be in line with the recommendations of the Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD). For the testing of other types of detectors, or detectors working on different principles, ISO 7240-15:2014 can be used only for guidance. Detectors with special characteristics, developed for specific risks, are not covered in ISO 7240-15:2014.
