This Standard sets forth requirements for smoke-alarms, single-station and multiple-station type, rated 120 V or less, intended for open area protection in ordinary indoor locations. A smoke-alarm, as defined by these requirements, is a self-contained unit which consists of an assembly of electrical components including a smoke chamber, alarm-sounding appliance, and provision for connection to a power supply source, either by splice leads, terminals, a cord and plug arrangement, or containing integral batteries.
Amendment 1 contains revisions and additional requirements to the Standard that are intended to address new provisions in the 2010 National Building Code of Canada, and to facilitate the testing and evaluation of smoke alarms.
