Fire detection and fire alarm systems - Part 12: Smoke detectors - Line detectors using an optical beam

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.

Brandmeldeanlagen - Teil 12: Rauchmelder - Linienförmiger Melder nach dem Durchlichtprinzip

Diese Europäische Norm legt Anforderungen, Prüfverfahren und Leistungsmerkmale für linienförmige Melder nach dem Durchlichtprinzip fest, die Rauch durch die Auswertung der Dämpfung und/oder der Änderungen der Dämpfung eines optischen Strahls in Brandmelde- und Feueralarmanlagen, die in Gebäuden eingebaut sind, erkennen (siehe EN 54-1:2011).
Diese Europäische Norm sieht die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) von linienförmigen Meldern nach dem Durchlichtprinzip nach dieser EN vor.
Diese Europäische Norm behandelt nicht:
 linienförmige Melder nach dem Durchlichtprinzip, die für den Betrieb zwischen gegenüberliegenden Bestandteilen mit einem Abstand kleiner als 1 m ausgelegt sind;
 linienförmige Melder nach dem Durchlichtprinzip, deren optische Messstrecke mit einer inneren mechanischen Verbindung festgelegt wird oder einstellbar ist;
 linienförmige Melder nach dem Durchlichtprinzip mit speziellen Kenngrößen, die durch die Prüfverfahren nach dieser Europäischen Norm nicht bewertet werden können.
ANMERKUNG Der Begriff „optisch“ wird für den Bereich des elektromagnetischen Spektrums verwendet, der vom Sender erzeugt wird und für den der Empfänger empfindlich ist; dieser Begriff ist nicht auf sichtbare Wellenlängen beschränkt.

Systèmes de détection et d'alarme incendie - Partie 12 : Détecteurs de fumée - Détecteurs linéaires fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées

La présente Norme européenne spécifie les exigences, les méthodes d’essai et les critères de performance des détecteurs linéaires de fumée fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées qui détectent la fumée par atténuation et/ou par variation de l'atténuation d’un faisceau d’ondes optiques, utilisés dans les systèmes de détection et d’alarme incendie installés dans les bâtiments (voir l’EN 54-1:2011).
La présente Norme européenne prévoit l'évaluation et la vérification de la constance des performances (EVCP) des détecteurs linéaires fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées, par rapport à la présente EN.
La présente Norme européenne ne couvre pas :
-   les détecteurs linéaires fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées, conçus pour fonctionner avec des composants opposés ayant une portée inférieure à 1 m ;
-   les détecteurs linéaires fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées dont le parcours optique est défini ou réglé par une liaison mécanique intégrée ;
-   les détecteurs linéaires fonctionnant suivant le principe de la transmission d'un faisceau d'ondes optiques rayonnées possédant des caractéristiques particulières ne pouvant pas être évaluées par les méthodes d’essai de cette Norme européenne.
NOTE   Le terme « ondes optiques » décrit la partie du spectre électromagnétique produite par un émetteur et à laquelle un récepteur répond ; ce terme ne se limite pas aux longueurs d'ondes visibles.

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.

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.
