Fire detection and fire alarm systems - Part 20: Aspirating smoke detectors

This European Standard specifies the requirements, test methods and performance criteria for aspirating smoke detectors for use in fire detection and fire alarm systems installed in buildings.
Aspirating smoke detectors developed for the protection of specific risks that incorporate special characteristics (including additional features or enhanced functionality for which this standard does not define a test or assessment method) are also covered by this standard. The performance requirements for any special characteristics are beyond the scope of this standard.
NOTE   Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not therefore specified in this standard.

Brandmeldeanlagen - Teil 20: Ansaugrauchmelder

Diese Europäische Norm legt Anforderungen, Prüfverfahren und Leistungsmerkmale für Ansaugrauchmelder fest, die für Brandmeldeanlagen in Gebäuden eingesetzt werden.
Ansaugrauchmelder, die für bestimmte Risiken mit speziellen Eigenschaften entwickelt wurden (einschließlich zusätzlicher Merkmale oder mit erweiterte Funktionalität, für die diese Norm keine Prüfungen oder Nachweis¬verfahren festlegt), sind in dieser Norm nicht behandelt. Die Leistungsanforderungen für die speziellen Eigenschaften werden vom Anwendungsbereich dieser Norm nicht erfasst.
ANMERKUNG   Einige Meldertypen enthalten radioaktive Stoffe. Die nationalen Anforderungen für den Schutz gegen ionisierende Strahlung sind in den Ländern unterschiedlich und werden deshalb in der vorliegenden Norm nicht festgelegt.

Systèmes de détection et d'alarme incendie - Partie 20 : Détecteurs de fumée par aspiration

La présente Norme européenne spécifie les exigences, les procédures d’essai et les critères de performance pour les détecteurs de fumée par aspiration pour utilisation dans les systèmes de détection et d’alarme incendie installés dans les bâtiments.
Les détecteurs de fumée par aspiration conçus pour la protection contre des risques spécifiques comportant des caractéristiques particulières (y compris des propriétés supplémentaires ou une fonctionnalité améliorée pour lesquels la présente norme ne définit pas d’essai ou de méthode d’évaluation) ne sont pas couverts par la présente norme. Les exigences de performance pour toute caractéristique particulière sortent du domaine d’application de la présente norme.
NOTE   Certains types de détecteurs peuvent contenir des matériaux radioactifs. Les exigences nationales pour la protection contre les rayonnements varient d’un pays à l’autre et ne sont par conséquent pas spécifiées dans la présente norme.
