|ICS Code (Fire protection):||13.220.20|
This Standard sets forth requirements for smoke detectors and accessories, including mechanical guards to be employed in ordinary indoor locations in accordance with the following: In the United States:
a) National Fire Alarm and Signaling Code, NFPA 72. In Canada:
b) Standard for the Installation of Fire Alarm Systems, CAN/ULC-S524;
c) National Building Code of Canada; and
d) National Fire Code of Canada.
A smoke detector (e.g. ionization-type, photoelectric-type, smoke detector with supplementary heat detection type, combination smoke type, multi-criteria type) as covered by this Standard consists of an assembly of electrical components arranged to detect one or more products of combustion. At a minimum the detector shall contain a smoke (particulate) sensor. The products of combustion may consist of visible as well as invisible smoke particles, gases, heat, radiant energy, and water vapor.. The detector includes provision for the connection to a source of power, signaling, and optional remote control circuits. Additional functionality, such as a heat detector, heat sensor, or audible signaling appliance/device, is permitted to be incorporated as part of the smoke detector assembly.
This standard covers the following types of detectors:
a) Detectors intended for open area protection and for connection to a compatible power supply or control unit for operation as part of a fire alarm system.
b) Detectors intended solely for control of releasing devices such as electromagnetic door holders, fire dampers or smoke dampers.
c) Detectors intended for both applications described in (a) and (b) above, and
d) In Canada, duct detectors.
