本文件规定了使用散射光、透射光或电离的烟雾报警器的要求、试验方法、性能标准和制造商说明，适用于家庭或类似住宅应用。 对于测试其他类型的烟雾报警器，或根据不同原理工作的烟雾报警器，建议仅将本文件作为指南。本文件不包括针对特定风险开发的具有特殊特性的烟雾报警器。 本文件允许（尽管不要求）在烟雾报警器中包含以下设施: -？目视故障状态指示； -？扩展温度范围操作； -？与其他类似烟雾报警器或附件的互连； -？暂时残疾； -？警报消声； -？信号频率特性； -？备用电源低状态静音； -？带有声音的烟雾报警器； -？使用射频链路的烟雾报警器； -？应对缓慢发展的火灾（漂移补偿）。 如果包括此类设施，本文件规定了适用要求。 本文件不包括拟并入使用单独控制和指示设备的系统中的装置。 ISO？7240系列中规定了此类系统。

This document specifies requirements, test methods, performance criteria and manufacturers' instructions for smoke alarms that operate using scattered light, transmitted light or ionization, and are intended for household or similar residential applications. For the testing of other types of smoke alarms, or smoke alarms working on different principles, this document is recommended only as guidance. Smoke alarms with special characteristics and developed for specific risks are not covered by this document. This document allows, although it does not require, the inclusion within the smoke alarm of facilities for the following: —？visual fault condition indication; —？extended temperature-range operation; —？interconnection with other similar smoke alarms or accessories; —？temporary disablement; —？alarm silencing; —？signal frequency characteristics; —？standby power source low condition silence; —？smoke alarms with voice; —？smoke alarms using radio frequency links; —？response to slowly developing fires (drift compensation). Where such facilities are included, this document specifies applicable requirements. This document does not cover devices intended for incorporation in systems using separate control and indicating equipment. Such systems are specified in the ISO？7240 series.
