This European Standard specifies requirements, test methods, performance criteria, and manufacturer's instructions for self-contained smoke alarms that operate using scattered light, transmitted light, or ionization, intended for household or similar residential applications. The smoke alarms described in this Standard are also suitable for use in leisure accommodation vehicles (LAVs). For the testing of other types of smoke alarms, or smoke alarms working on different principles, this standard should only be used for guidance. Smoke alarms with special features, such as radio interlinking or special characteristics and developed for specific risks are not covered by this standard. This standard does not cover devices intended for incorporation in systems using separate control and indicating equipment.
