Standard for the Installation of Fire Alarm Systems

Published by: Underwriters Laboratories of Canada / 2014-08-27
This Standard describes the requirements for the design and installation of a fire alarm system with or without voice communication capability, as defined in Section 3, Glossary.

This Standard is intended to apply to both required and voluntary fire alarm installations. The requirements in this Standard address the installation for various types of fire alarm system equipment and devices. These requirements are intended to apply when the equipment and devices are required by the fire alarm system design.

This Standard recognizes that a fire alarm system may have additional features or functions differing from those detailed in these requirements, if the features or functions enhance:

  • A the life safety of the occupants of the building; and/or
  • B the protection of the building or property.

Refer to Appendix A (Informative) Explanatory Materials, Clause A1.1.
The installation of fire detection and alarm devices not covered by these requirements shall be in accordance with good engineering practice and manufacturer?s published installation instructions.

La présente norme énonce les exigences relatives à la conception et à l’installation d’un système d’alarme incendie doté ou non d’un réseau de communication phonique, tel qu’il est defini à la section 3, Glossaire : La présente norme est destinée à s’appliquer aux installations de systemes d’ alarme incendie obligatoires et volontaires.

Cette norme traite des exigences relatives à l’installation de differents types d’équipement et de dispositifs du systeme d’alarme incendie. Ces exigences s’appliquent lorsque la conception du systeme d’alarme incendie exige cet équipement et ces dispositifs.

L’installation des dispositifs de détection d’incendie et d’alarme incendie que ne visent pas ces
exigences doit etre conforme à des pratiques d?ingénierie reconnues et aux directives d’installation publiées par le fabricant. Lorsqu’une conception axée sur la performance est utilisée pour un systeme d’alarme incendie, la conception doit etre soumise à l’autorité competente aux fins d’examen et d’approbation. Les renseignements soumis à l’autorité competente doivent comprendre la documentation exigee prescrite par l’autorité compétente, ainsi que les calculs, les modélisations ou toute autre documentation technique utilisée dans l’élaboration de la conception du système d’alarme incendie.

This replaces the CAN/ULC-S527-11, Third Edition Standard for Control Units for Fire Alarm Systems.

This Standard covers requirements for control units, fire alarm systems and control unit accessories for
use in accordance with CAN/ULC-S524, Standard for the Installation of Fire Alarm Systems, 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. This edition of the standard was updated to
address technological advancements.

Standard Methods of Fire Endurance Tests of Building Construction and Materials

Published by: Underwriters Laboratories of Canada / 2014-08-01
“This Standard covers fire endurance tests applicable to walls, partitions, floors, roofs, ceilings, columns, beams, and girders, as well as to some components of these building sub-assemblies.

It is the intent that the fire endurance period established by this test method indicates performance only during the fire exposure period and shall not be construed as having determined suitability for use after fire exposure.

The fire exposure and hose stream tests are not intended to be representative of all fire conditions. It is likely that conditions will vary with changes in the amount, nature and distribution of fire, loading, ventilation, size and configuration of assembly installed. This fire endurance test Standard provides a relative measure of fire performance of comparable assemblies under specified fire exposure conditions.

This new edition includes test requirements to address loaded unrestrained beams using the deflection criteria as an alternative to the beam temperature criteria.”

Live Working – Minimum Approach Distances For A.C. Systems In The Voltage Range 72,5 Kv To 800 Kv – A Method Of Calculation

Published by: Underwriters Laboratories of Canada / 2014-06-01
This identical adoption of the Third Edition of IEC 61472 is an update to the Second Edition and is the First Edition of CAN/ULC-61472. Updates include clarification of the scope, review of the definitions and review of the Annexes. Other updates to the Third Edition also include modification of calculations as well as introduction of new criteria and tables.

This International Standard describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and/or workers at different electric potentials.

The required withstand voltage and minimum approach distances calculated by the method described in this standard are evaluated taking into consideration the following:

  • workers are trained for, and skilled in, working in the live working zone;
  • the anticipated overvoltages do not exceed the value selected for the determination of the
    required minimum approach distance;
  • transient overvoltages are the determining overvoltages;
  • tool insulation has no continuous film of moisture or measurable contamination present on
    the surface;
  • no lightning is seen or heard within 10 km of the work site;
  • allowance is made for the effect of conducting components of tools;
  • the effect of altitude, insulators in the gap, etc, on the electric strength is taken into consideration.
    • For conditions other than the above, the evaluation of the minimum approach distances may require specific data, derived by other calculation or obtained from additional laboratory investigations on the actual situation.

This Standard sets forth minimum requirements for steel, non-pressure tanks that are used for the
aboveground storage of mmable and combustible liquids compatible with the material of construction
and with a specific gravity not greater than 1.0.

NOTE: These tanks may also be used for the storage of used oil. For tanks intended solely for the
collection of used oil, refer to CAN/ULC-S652, Standard for Tank Assemblies for the Collection of
Used Oil. This Standard covers tanks, which are fabricated, inspected and tested for leakage before
shipment from the factory. This Standard covers the construction of tanks for use in stationary
installations. Tanks fabricated in accordance with this Standard are not intended for the
transportation of flammable and combustible liquids nor are they intended to be transported while
containing such liquids. NOTE: Relocation of tanks other than utility tanks is subject to the
requirements of the authority having jurisdiction. Section 4 of this Standard covers the construction of
single wall tanks. Section 5 covers the construction of tanks with secondary containment. This
Standard also covers aboveground steel, rectangular, non-pressure workbench tanks for the
combined use as a working surface and storage of lubricating oils having capacities up to and
including 2500 L. This Standard also covers aboveground steel, rectangular, non-pressure, generatorbase
tanks. This Standard also covers utility tanks and double bottom utility tanks designed to allow
for location as required by their intended service. These tanks are for installation at locations such as
farms, construction sites, demolition sites, exploration sites, forestry operations and similar locations.
This Standard does not cover wind loading or seismic loading of tanks. However, Guidelines for the
Maximum Structural Limitations for Vertical Tanks (A2) are included in Appendix A (Informative),
Explanatory Materials.
