National foreword

This British Standard is the UK implementation of EN 54‑12:2015. It supersedes BS EN 54‑12:2002 which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee FSH/12/2, Fire detectors.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 April 2015.

This European Standard was approved by CEN on 1 February 2015.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

Foreword

This document (EN 54‑12:2015) has been prepared by Technical Committee CEN/TC 72 “Fire detection and fire alarm systems”, the secretariat of which is held by BSI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2015, and conflicting national standards shall be withdrawn at the latest by April 2019.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 54‑12:2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of Regulation (EU) 305/2011.

For relationship with EU Regulations see informative Annex ZA, which is an integral part of this document.

EN 54‑12 has been revised so as to align with the second answer to Mandate M/109. It includes new clauses and annexes as follows:

Clause 6 Assessment and verification of constancy of performance (AVCP);
Clause 7 Classification and designation;
Clause 8 Marking, labelling and packaging;
Annex H (informative) Information concerning the requirements for the response to slowly developing fires;
Annex I (informative) Data supplied with line detectors using an optical beam.

The main technical changes are as follows:

The definition of response value has been modified so that it relates the same smoke density for line detectors using an optical beam both with and without a separate reflector.
Changes to the test conditions and requirements for the Tolerance to beam misalignment test and the Vibration (endurance) test.

EN 54, Fire detection and fire alarm systems, consists of the following parts:

Part 1: Introduction;
Part 2: Control and indicating equipment;
Part 3: Fire alarm devices - Sounders;
Part 4: Power supply equipment;
Part 5: Heat detectors — Point detectors;
Part 7: Smoke detectors — Point detectors using scattered light, transmitted light or ionization;
Part 10: Flame detectors — Point detectors;
Part 11: Manual call points;
Part 12: Smoke detectors — Line detectors using an optical light beam [the present document];
Part 13: Compatibility assessment of system components;
Part 14: Guidelines for planning, design, installation, commissioning, use and maintenance [CEN Technical Specification];
Part 16: Voice alarm control and indicating equipment;
Part 17: Short circuit isolators;
Part 18: Input/output devices;
Part 20: Aspirating smoke detectors;
Part 21: Alarm transmission and fault warning routing equipment;
Part 22: Resettable line-type heat detectors [currently at acceptance stage];
Part 23: Fire alarm devices — Visual alarms devices;
Part 24: Components of voice alarm systems — Loudspeakers;
Part 25: Components using radio links;
Part 26: Carbon monoxide detectors — Point detectors;
Part 27: Duct smoke detectors;
Part 28: Non-resettable line type heat detectors [currently at drafting stage];
Part 29: Multi-sensor fire detectors — Point detectors using a combination of smoke and heat sensors;
Part 30: Multi-sensor fire detectors — Point detectors using a combination of carbon monoxide and heat sensors;
Part 31: Multi-sensor fire detectors — Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors;
Part 32: Planning, design, installation, commissioning, use and maintenance of voice alarm systems [currently at acceptance stage].

NOTE This list includes standards that are in preparation and other standards may be added. For current status of published standards refer to www.cen.eu .

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

1 Scope

This European Standard specifies requirements, test methods and performance criteria for line detectors using an optical beam that detect smoke by utilizing the attenuation and/or changes in attenuation of an optical beam, for use in fire detection and fire alarm systems installed in buildings (see EN 54‑1:2011).

This European Standard provides for the assessment and verification of constancy of performance (AVCP) of line detectors using an optical beam to this EN.

This European Standard does not cover:

line detectors using an optical beam designed to operate with separations between opposed components of less than 1 m;
line detectors using an optical beam whose optical path length is defined or adjusted by an integral mechanical connection;
line detectors using an optical beam with special characteristics, which cannot be assessed by the test methods in this European Standard.

NOTE The term “optical” is used to describe that part of the electromagnetic spectrum produced by the transmitter to which the receiver is responsive; this is not restricted to visible wavelengths.
