This document specifies requirements, test methods, performance criteria, and manufacturer\'s instructions for smoke alarms that operate using scattered light, transmitted light, or ionization, intended for household or similar residential application. Requirements for smoke alarms suitable for use in leisure accommodation vehicles are also included.

This document specifies requirements, test methods, performance criteria, and manufacturer\'s instructions for smoke alarms that operate using scattered light, transmitted light or ionization, intended for household or similar residential application.

This document includes additional requirements for smoke alarms, which are also suitable for use in leisure accommodation vehicles.

For the testing of other types of smoke alarms, or smoke alarms working on different principles, this document should only be used for guidance. AC1 Special features of smoke alarms, such as radio interlinking or special characteristics and developed for specific risks, are not covered by this document. AC1

This document allows, although it does not require, the inclusion within the smoke alarm of facilities for interconnection with other similar smoke alarms and/or accessories, and for alarm silencing. 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.

NOTE Certain types of smoke alarms contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this document. Such smoke alarms should, however, comply with the applicable national requirements.
