ULC CAN/ULC 559:2024 Standard for Equipment for Fire Signal Receiving Centres and Systems

PREFACE

This is the Third Edition of CAN/ULC 559, Standard for Equipment for Fire Signal Receiving Centres and Systems.

This Edition of the Standard was developed by the ULC Standards Working Group on Equipment for Fire Signal Receiving Centres and Systems, reviewed by the ULC Standards Subcommittee on Control Units for 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 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.

Annexes A and B, identified as Informative, are for information 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.

This Third Edition National Standard of Canada is based on, and now supersedes, the Second Edition CAN/ULC 559.

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 559 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

d) CSA-22.1, Canadian Electrical Code, Part l, Safety Standard for Electrical Installations; and

e) Figure 1.1, Typical Arrangement of Equipment for Fire Signal Receiving Centres and Systems.

1.2 Proprietary fire alarm systems incorporating the features and functions of a fire alarm system, and/or incorporating transponders of distributed type systems, shall be in accordance with the requirements of CAN/ULC 527, Standard for Control Units for Fire Alarm Systems.

1.3 Equipment covered by the scope of this Standard incorporating the features and functions of a fire alarm system, shall be in accordance with the requirements of CAN/ULC 527, Standard for Control Units for Fire Alarm Systems.

1.4 These requirements cover fire signal receiving centre systems, including protected premise unit and receiver for ordinary (non-hazardous) indoor and outdoor locations.

1.5 Changes or additions to the equipment covered by the scope of this Standard shall be tested according to the relevant sections of this Standard. Examples of changes and additions include, but are not limited to:

a) Operating system programme;

b) Changes or additional features to system operation;

c) Electrical/electronic or mechanical components; and

d) Other software temporarily or permanently installed; such as for test or maintenance.

1.6 Programming methods, test, service and other software intended for use with the equipment for fire signal receiving centres and systems shall be included in the evaluation of this equipment.

1.7 The term product as used in this Standard refers to all items of equipment covered by the scope of this Standard.

1.8 Unless otherwise indicated, all AC voltage and current values mentioned in this Standard are root mean-square (rms).

1.9 The requirements of this Standard apply uniformly to all equipment covered by the scope of this Standard regardless of whether they are used as a component of a fire signal receiving centre and systems or separately enclosed and referred to as an accessory.

1.10 Signal receiving units used in fire signal receiving centres, satellite centres, signal processing centres and bridging centres shall comply with the requirements of this Section.

1.11 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 559. 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 559-xx” (where xx represents the edition of the Standard that they were previously in compliance with).
