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

This European Standard 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.
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 one member state to another and are not specified in this standard.

Brandmeldeanlagen - Teil 27: Rauchmelder für die Überwachung von Lüftungsleitungen

Diese Europäische Norm 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.
Rauchmelder für die 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 Mitgliedstaaten unterschiedlich und werden deshalb in der vorliegenden Norm nicht festgelegt.

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

La présente Norme européenne spécifie les exigences, les méthodes d’essai et les critères de performance pour les détecteurs d’incendie qui détectent la fumée dans les conduits d’air des bâtiments en tant que partie intégrante d’un système de détection et d’alarme incendie ou en tant qu’actionneur d’un système de protection contre l’incendie.
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 peuvent contenir des matériaux radioactifs. Les exigences nationales pour la protection contre les rayonnements varient d’un État membre à l’autre et ne sont par conséquent pas spécifiées dans la présente norme.

Sistemi za odkrivanje in javljanje požara ter alarmiranje - 27. del: Dimni javljalnik za prezračevalne kanale

Ta dokument določa zahteve, preskusne metode in merila učinkovitosti za javljalnike požara, ki zaznavajo prisotnost dima v prezračevalnih kanalih stavb kot del sistema za odkrivanje in javljanje požara ter alarmiranje ali kot sprožilo za sistem zaščite pred požarom. Pri preskušanju drugih vrst dimnih javljalnikov ali dimnih javljalnikov z drugačnim načinom delovanja se lahko ta dokument uporabi samo kot smernica. Dimni javljalniki za prezračevalne kanale s posebnimi značilnostmi, ki so razviti za posebna tveganja, niso zajeti v tem dokumentu. OPOMBA: Nekatere vrste javljalnikov vsebujejo radioaktivne materiale. Nacionalne zahteve za zaščito pred sevanjem se razlikujejo po posameznih državah in niso določene v tem standardu.
