STANDARD FOR SMOKE ALARMS
|Publication Date:||1 October 2002|
|ICS Code (Alarm and warning systems):||13.320|
|ICS Code (Fire protection):||13.220.20|
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.
Smoke-alarms not intended for interconnection are defined as single-station type.
Smoke-alarms which may be interconnected so that actuation of one results in alarm sounding by all interconnected units are defined as multiple-station type.
The manufacture, importation, distribution, and disposal of smoke-alarms containing radioactive material are subject to the safety requirements of the Canadian Nuclear Safety Commission.
Verification of this acceptance of smoke-alarms by the Canadian Nuclear Safety Commission is required prior to the acceptance of the smoke-alarm to establish compliance with the requirements of this Standard.
