CAN/ULC-S529-M87

1. SCOPE 1.1 This Standard sets forth requirements for ionization-type and photoelectric-type detectors, rated at 300 V or less, to be employed in ordinary indoor locations in accordance with the following: A Standard for the Installation of Fire Alarm Systems, CAN/ULC-S524M; B Standards of the National Fire Protection Association: No. 71, Central Station Signaling Systems; No. 72B, Auxiliary Protective Signaling Systems; No. 72C, Remote Station Protective Signaling Systems; No. 72D, Proprietary Protective Signaling Systems; No. 74 Household Fire Warning Equipment. 1.2 A smoke detector (e.g. ionization-type, photoelectric-type and the like) as covered by this Standard consists of an assembly of electrical components arranged to detect one or more products of combustion. The products of combustion may consist of gases, water vapor, and visible as well as invisible smoke particles. The detector includes provision for the connection to a source of power, signalling, and optional remote control circuits. 1.3 This Standard covers the following types of detectors: A Detectors intended for open area protection, for connection to compatible 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, etc; C Detectors suitable for the uses in Items A and B above; and D Duct detectors. 1.4 This Standard does not cover the following: A Detectors for monitoring the smoke density within flues or stacks; B Power supplies and control units to which the detectors are intended to be connected. These are covered under the Standard for Control Units for Fire Alarm Systems, CAN/ULC-S527M. 1.5 The manufacture, importation, distribution, and disposal of smoke detectors containing radioactive material are subject to the safety requirements of the Atomic Energy Control Board of Canada. 1.6 Verification of the acceptance of such detectors by the regulating agency involved is required prior to the investigation of the detector to establish compliance with the requirements of this Standard.
