These requirements cover electrically operated single and multiple station smoke alarms intended for open area protection in indoor locations and portable smoke alarms used as ??avel??larms in accordance with: In Canada: a) Installation of Smoke Alarms@ CAN/ULC-S553; b) National Building Code of Canada; and c) National Fire Code of Canada. In the United States: d) National Fire Alarm and Signaling Code@ NFPA 72; e) Standard for Recreational Vehicles@ NFPA 501C@ for smoke alarms intended for use in recreational vehicles; f) For smoke alarms intended for use in recreational boats: 1) Fire Protection Standard for Pleasure and Commercial Motor Craft@ NFPA 302@ 2) AC and DC Electrical Systems on Boats@ ABYC E-11@ and 3) The applicable regulations of the United States Coast Guard. A single station smoke alarm (e.g. ionization-type@ photoelectric-type@ smoke alarm with supplementary heat detection type@ combination smoke type@ multi-criteria type)@ as defined by these requirements@ is a self-contained fire alarm device that consists of an assembly of electrical components including a smoke sensor/ 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 to detect one or more products of combustion. The products of combustion may consist of visible as well as invisible smoke particles@ gases@ heat@ radiant energy@ and water vapor. Additional functionality such as@ a supplemental heat detector@ terminals for connection to a remote audible signaling appliance (device) or accessory@ and an integral transmitter to energize a remote audible signaling appliance (device) is permitted to be incorporated as part of the smoke alarm assembly. Smoke-alarms not intended for interconnection are defined as single-station type. Multiple station units are single station smoke alarms that are: a) Interconnected so that actuation of one results in alarm sounding by all interconnected smoke alarms@ or b) Smoke alarms that are connected to remote heat detectors or heat alarms. These requirements@ where applicable@ also cover all remote accessories that are to be connected. This standard does not cover the following: a) Smoke detectors of the non-self-contained type that are intended for connection to a household or industrial system control unit. These are included in the Standard for Smoke Detectors for Fire Protective Signaling Systems@ UL 268 or CAN/ULC-S529@ Smoke Detectors for Fire Alarm Systems. b) Mechanically operated single and multiple station fire alarm devices that are specified in the Standard for Single and Multiple Station Heat Alarms@ UL 539 or ULC/ORD-C539; c) Heat detectors ?C except for the requirements in the Fire Test ?C Smoke Alarm with Heat Detection @ Clause 69) incorporated as part of a single station smoke alarm assembly whose requirements are covered in the Standard for Heat Detectors for Fire Alarm Signaling Systems@ UL 521 or CAN/ULC-S530@ Heat Actuated Fire Detectors for Fire Alarm Systems and/or when part of a multi-criteria smoke alarm. d) An accessory that is provided with a means to transmit alarm signals to a constantly attended@ remote monitoring location. Any accessory capable of transmitting these types of signals is covered by the requirements in the Standard for Household Fire-Warning System Units@ UL 985 or CAN/ULC-S545@ Residential Fire Warning System Control Units; e) A gas and vapor detector or sensor incorporated as a part of a smoke alarm assembly and covered by the Standard for Single and Multiple Station Carbon Monoxide Alarms@ UL 2034@ or CSA 6.19-01 (R2006)@ Standard for Carbon Monoxide Alarming Devices except when part of a multi-criteria smoke alarm.
