Fire detection and fire alarm systems - Part 26: Carbon monoxide detectors - Point detectors

This European Standard specifies requirements, test methods and performance criteria for point detectors using carbon monoxide sensing for use in fire detection and fire alarm systems in and around buildings (see EN 54 1:2011).
This European Standard provides for the assessment and verification of consistency of performance (AVCP) of carbon monoxide point detectors to this EN.
This European Standard does not cover fire detectors incorporating at least one CO sensing element in combination with other elements sensing different fire phenomena.
CO detectors having special characteristics suitable for the detection of specific fire risks are not covered by this European Standard. The performance requirements for any additional functions are beyond the scope of this European Standard (e.g. additional features or enhanced functionality for which this standard does not define a test or assessment method).

Diese Europäische Norm sieht die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP, en: assessment and verification of consistency of performance ) von punktförmigen Kohlenmonoxidmeldern nach dieser EN vor.
Nicht Gegenstand dieser Europäischen Norm sind Brandmelder, die neben mindestens einem CO-Sensor in Kombination andere Sensoren zum Erkennen unterschiedlicher Brandkenngrößen enthalten.
CO-Brandmelder mit speziellen Merkmalen, die zur Erkennung besonderer Brandgefahren geeignet sind, sind nicht Gegenstand dieser Europäischen Norm. Die Leistungsanforderungen an zusätzliche Funktionen liegen nicht im Anwendungsbereich dieser Europäischen Norm (z. B. zusätzliche Merkmale oder erweiterter Funktionsumfang, für den die vorliegende Norm keine Prüf- oder Bewertungsverfahren festlegt).

Système de détection et d'alarme incendie - Partie 26: Détecteurs de monoxide de carbone - Détecteurs ponctuels

La présente Norme européenne spécifie les exigences, les méthodes d'essais et les critères de performance des détecteurs ponctuels fonctionnant suivant le principe de la détection de monoxyde de carbone, utilisés dans les systèmes de détection et d'alarme incendie installés dans et autour des 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 ponctuels de monoxyde de carbone par rapport à la présente EN.
La présente Norme européenne ne prend pas en compte les détecteurs d'incendie qui combinent au moins un élément de détection de CO avec d'autres éléments de détection de différents phénomènes d'incendie.
Les détecteurs de CO possédant des caractéristiques particulières adaptées à la détection des risques d'incendie spécifiques ne sont pas pris en compte par la présente Norme européenne. Les exigences de performance relatives à toute autre fonction supplémentaire ne relèvent pas du domaine d'application de la présente Norme européenne (par exemple, caractéristiques supplémentaires ou fonctionnalité améliorée pour lesquelles la présente norme ne définit pas de méthode d'essai ou d'évaluation).

Introduction

Carbon monoxide (CO) is a product of the incomplete combustion of carbon-based materials. CO fire

detectors can react promptly to smouldering fires involving carbonaceous materials because CO does not

depend solely on convection, but also moves by diffusion. CO fire detectors might be better suited to

applications where other fire detection techniques are prone to false alarms, i.e. due to dust, steam and

cooking vapours.

The purpose of this standard is to ensure that carbon monoxide (CO) fire detectors have adequate sensitivity

and reliability for use in fire detection and fire alarm systems for residential commercial and industrial

premises. CO may not be produced in detectable quantities where pyrolysis of material rather than self-

sustained combustion occurs (e.g. overheating cables) or in the early stages of rapidly burning flaming fires

(e.g. liquid fuel fires). It is important that carbon monoxide fire detectors are only used where a risk

assessment indicates that they are appropriate for detecting the types of fires that may occur. CO fire

detectors should not be considered as a direct replacement for smoke detectors. CO fire detectors detect

carbon monoxide gas rather than the smoke particulates detected by optical and ionization smoke detectors.

A number of different methods for sensing CO are suitable. However, most sensors will also be influenced by

other gases and phenomena. Tests have therefore been included in the test schedule to assess cross-

sensitivity to substances normally present in the service environment that may affect the performance of the

detector.

As CO detectors are specifically well suited for the detection of incipient fires rather than flaming fires this

standard only includes tests to verify performance in smouldering fires. For this purpose, test fires TF2 and

TF3 from EN 54-7 have been included in the test schedule. An additional validity criterion has been added to

each of these tests to make them suitable for evaluating CO fire detectors.

1 Scope

This European Standard specifies requirements, test methods and performance criteria for point detectors

using carbon monoxide sensing for use in fire detection and fire alarm systems in and around buildings

(see EN 54-1:2011).

This European Standard provides for the assessment and verification of consistency of performance (AVCP)

of carbon monoxide point detectors to this EN.

This European Standard does not apply to fire detectors incorporating at least one CO sensing element in

combination with other elements sensing different fire phenomena.

CO detectors having special characteristics suitable for the detection of specific fire risks are not covered by

this European Standard. The performance requirements for any additional functions are beyond the scope of

this European Standard (e.g. additional features or enhanced functionality for which this standard does not

define a test or assessment method).
