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 smoke detectors utilising the attenuation and/or changes in attenuation of an optical beam, for use in fire detection systems installed in buildings.  This European Standard does not cover:
- Line smoke detectors designed to operate with separations between opposed components of less than 1 m;
- Line smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection;
- Line smoke detectors with special characteristics developed for specific risks.
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.

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 de fumée linéaires fonctionnant suivant le principe de l'atténuation et/ou de la variation de l'atténuation d'un faisceau ondes optiques, utilisés dans les systèmes de détection et d'alarme incendie installés dans les bâtiments.
La présente Norme européenne ne couvre pas :
a)   les détecteurs de fumée linéaires conçus pour fonctionner avec des composants opposés ayant une portée inférieure à 1 m ;
b)   les détecteurs de fumée linéaires dont le parcours optique est défini ou réglé par une liaison mécanique intégrée ;
c)   les détecteurs de fumée linéaires possédant des caractéristiques particulières ne pouvant pas être évaluées par les méthodes d'essai de la présente 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.
