ISO 7240-15:2014规定了使用烟雾和热传感器的点式火灾探测器的要求、试验方法和性能标准，该探测器在一个机械外壳中包括至少一个烟雾传感器和至少一个其他响应热量的传感器，并且烟雾传感器的信号与热传感器的信号相结合。 ISO 7240-15:2014涵盖的探测器内单个传感器的性能不足以符合ISO 7240中关于单个传感器探测器的其他部分。 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各不相同，因此本标准未对其进行规定。然而，此类探测器应符合国家要求，并符合经济合作组织核能机构（NEA）的建议- 运营与发展（OECD）。 对于其他类型的探测器或工作原理不同的探测器的测试，ISO 7240-15:2014仅可用于指导。ISO 7240-15:2014未涵盖针对特定风险开发的具有特殊特性的探测器。

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.
