Fire detection and fire alarm systems - Part 27: Duct smoke detectors

This document specifies requirements, test methods and performance criteria for fire detectors which detect smoke in air ducts in buildings as a part of a fire detection and fire alarm system or as an actuator for a fire protection system.
For the testing of other types of smoke detectors, or smoke detectors working on different principles, this document can be used only for guidance.
Duct smoke detectors with special characteristics and developed for specific risks are not covered by this document.
NOTE   Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and are not specified in this standard.

Brandmeldeanlagen - Teil 27: Rauchmelder zur Überwachung von Lüftungsleitungen

Dieses Dokument legt Anforderungen, Prüfverfahren und Leistungsmerkmale für automatische Brandmelder
fest, die Rauch in Lüftungsleitungen erkennen und in Gebäuden als Bestandteil einer Brandmeldeanlage für
Gebäude oder als Auslöseeinrichtung für eine automatische Brandschutzeinrichtung eingesetzt werden.
Für die Prüfung anderer Typen von Rauchmeldern oder von Rauchmeldern, die nach anderen Prinzipien
arbeiten, kann dieses Dokument lediglich als Leitfaden verwendet werden.
Rauchmelder zur Überwachung von Lüftungsleitungen mit besonderen Eigenschaften und für besondere
Gefahren sind nicht Gegenstand dieser Norm.
ANMERKUNG Einige Meldertypen enthalten radioaktive Stoffe. Die nationalen Anforderungen für den Schutz gegen
ionisierende Strahlung sind in den Mitgliedsstaaten unterschiedlich und werden deshalb in der vorliegenden Norm nicht
festgelegt.

Systèmes de détection et d'alarme incendie - Partie 27 : Détecteur de fumées dans les conduits

Le présent document spécifie les exigences, les méthodes d'essai et les critères de performance des détecteurs d’incendie, détectant la fumée dans les conduits d’air de bâtiments, et faisant partie d’un système de détection et d’alarme incendie ou comme un organe de commande d’un système de protection incendie.
Le présent document peut être utilisé comme guide pour les essais d’autres types de détecteurs de fumée, ou pour ceux fonctionnant sur des principes différents.
Les détecteurs de fumée dans les conduits, possédant des caractéristiques particulières, conçus pour des risques spéciaux, ne sont pas couverts par ce document.
NOTE   Certains types de détecteurs contiennent des matières radioactives. Les exigences nationales pour la protection contre les radiations étant différentes d'un pays à l'autre, celles-ci ne sont donc pas spécifiées dans la présente norme.

Introduction
Duct smoke detectors (DSD) are used as part of a fire detection and fire alarm system or as a stand alone
actuator for a fire protection system to sample the environment within air ducts of a building. Detection of
smoke will release a signal to the connected control and indicating equipment and may be used as a signal to
an air-handling system to prevent the spread of smoke within the building.
A DSD is required to function satisfactorily not only in the event of a fire, but also during and after exposure to
conditions likely to be met in practice such as corrosion, vibration, direct impact, indirect shock and
electromagnetic interference. Some tests specified are intended to assess the performance of the DSD under
such conditions.
The performance of DSD is assessed from results obtained in specific tests. This document is not intended to
place any other restrictions on the design and construction of such equipment.
A stand alone system is given in Figure 1. An example for a configuration of a fire detection and fire alarm
system is given in Figure 2, see also EN 54-1.
