ULC CAN/ULC 573:2024 Standard for Installation of Ancillary Devices Connected to Fire Alarm Systems

PREFACE

This is the First Edition National Standard of the Standard for Installation of Ancillary Devices Connected to Fire Alarm Systems, CAN/ULC 573.

This Edition was developed by the ULC Standards Working Group on S573, reviewed by the ULC Standards Subcommittee on Installation, Inspection and Verification of Fire Alarm Systems and was formally approved by the ULC Standards Committee on Fire Alarm and Life Safety Equipment and Systems.

This Standard has been developed in compliance with the requirements of Standards Council of Canada (SCC) for accreditation of a Standards Development Organization.

Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.

Appendix A, identified as informative, is for informational purposes only.

In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages.

Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. ULC Standards shall not be held responsible for identifying any or all such patent rights.

Requests for interpretation of this Standard should be sent to ULC Standards. The requests should be worded in such a manner as to permit a “yes” or “no” answer based on the literal text of the requirement concerned.

This CAN/ULC 573 Standard is under continuous maintenance, whereby each revision is approved in compliance with the requirements of SCC for accreditation of a Standards Development Organization. In the event that no revisions are issued for a period of four years from the date of publication, action to revise, reaffirm, or withdraw the standard shall be initiated.

Comments or proposals for revisions on any part of the Standard may be submitted at any time. Proposals should be submitted via a Proposal Request in the Collaborative Standards Development System (CSDS) at https://csds.ul.com.

This Standard is intended to be used for conformity assessment.

SCOPE

1.1 This Standard describes the requirements for the application and installation of ancillary devices which interact with a fire alarm system. This Standard shall be applied in conjunction with ULC-S524, Standard for Installation of Fire Alarms Systems.

NOTE: This Standard is intended to apply to ancillary device installations for both required and voluntary fire alarm system installations. See Appendix A (Informative) Explanatory Materials, Clause A1.1.

1.2 The installation of ancillary devices not covered by these requirements shall be in accordance with good engineering practice and manufacturer's installation guidelines.
