Standard for Control Unit for Fire Alarm Systems
Scope:
This Standard covers requirements for control units, fire alarm systems and control unit accessories for use in accordance with the Standard for the Installation of Fire Alarm Systems, CAN/ULC-S524, in accordance with Rule 32-004(1) of C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part I; and the National Building Code of Canada. This Standard also covers smoke control features when incorporated as a part of the control equipment, releasing device service and stand-alone power supplies. Where a fire alarm system is shared by other systems for other than fire alarm operation, the non-fire functions shall not interfere with the required operation of the fire alarm system. This Standard does not cover replacement parts for fire alarm systems that consist of products or subassemblies of complete products manufactured in accordance with previous editions of ULC-S527.
Replacement parts that do not comply with the current edition of this Standard shall be manufactured in accordance with the edition of this Standard that they were previously in compliance with and shall be marked “For Replacement Only – Complies with ULC-S527-xx” (where xx represents the edition of the Standard that they were previously in compliance with).
If a fire alarm system incorporates the features and functions of a proprietary fire alarm system or fire signal receiving centre, then the requirements of CAN/ULC-S559, Equipment for Fire Signal Receiving Centres and Systems, shall also apply. Transponders of distributed type systems are classified as control units and the requirements of this Standard shall apply.
These requirements apply to control units and control unit accessories for ordinary (non- hazardous) indoor and outdoor locations. These requirements do not apply to field devices unless the device is used as a component of a control unit or control unit accessory. Test, service, and other software and programming methods, including software compare program, intended for use with the control unit shall be evaluated with the control units.
