SIST EN 54-31:2015

Fire detection and fire alarm system - Part 31: Multi-sensor fire detectors - Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors

This European Standard specifies requirements, test methods and performance criteria for point-type multi-sensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996), incorporating in one mechanical enclosure at least one optical or ionization smoke sensor and at least one carbon monoxide (CO) sensor and optionally one or more heat sensors. The overall fire detection performance is determined utilizing the combination of the detected phenomena.
This European standard specifies the evaluation of conformity (EoC) and the marking of the products concerned (i.e. multi-sensor fire detectors).
Multi-sensor fire detectors having special characteristics suitable for the detection of specific fire risks are not covered by this standard. The performance requirements for any additional functions are beyond the scope of this standard (e.g. additional features or enhanced functionality for which this standard does not define a test or assessment method).
NOTE   Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this standard.

Brandmeldeanlagen - Teil 31: Mehrfachsensor-Brandmelder-Punktförmige Melder mit Kombinierten Rauch-, CO-und optionalen Wärmesensoren

Diese Europäische Norm legt Anforderungen, Prüfverfahren und Leistungsmerkmale für punktförmige Mehrfachsensor-Brandmelder fest, die in Brandmeldeanlagen für Gebäude eingesetzt werden (siehe EN 54-1:1996) und die in einem Gehäuse mindestens einen Rauchsensor nach dem Durchlicht- oder Ionisationsprinzip und mindestens einen Kohlenmonoxid-(CO-)Sensor sowie optional einen oder mehrere Wärmesensoren enthalten. Ihre Gesamtleistung bei der Brandmeldung ergibt sich aus der Kombination der erkannten Brandphänomene.
Diese Europäische Norm legt Anforderungen an die Konformitätsbewertung und die Kennzeichnung der betreffenden Produkte fest (d. h. Mehrfachsensor-Brandmelder).
Mehrfachsensormelder mit speziellen Merkmalen, geeignet für die Erkennung besonderer Brandrisiken, sind nicht Gegenstand dieser Norm. Die Leistungsanforderungen an alle zusätzlichen Funktionen fallen nicht in den Anwendungsbereich dieser Norm (z. B. werden in dieser Norm für zusätzliche Merkmale oder für eine verbesserte Funktionstüchtigkeit keine Prüf- oder Bewertungsverfahren festgelegt).
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 31 : Détecteurs d'incendie multicapteurs - Détecteurs ponctuels combinant l'utilisation de capteurs de fumée, de capteurs de monoxyde de carbone et éventuellement de capteurs de chaleur

La présente Norme européenne spécifie les exigences, les méthodes d’essai et les critères de performance applicables aux détecteurs d’incendie ponctuels multicapteurs destinés à être utilisés dans les systèmes de détection d’incendie et d'alarme incendie installés dans les bâtiments et aux alentours (voir EN 54 1:2011), incorporant dans une seule enveloppe mécanique au moins un capteur de fumée optique ou à ionisation et au moins un capteur de monoxyde de carbone (CO) et éventuellement un ou plusieurs capteurs de chaleur, en utilisant la combinaison des phénomènes détectés. La présente Norme européenne traite uniquement des modes de fonctionnement, dans lesquels au moins les signaux des capteurs de fumée et des capteurs de monoxyde de carbone sont évalués en continu.
La présente Norme européenne prévoit l'évaluation et la vérification de la constance des performances (EVCP) des détecteurs ponctuels combinant l’utilisation de capteurs de fumée, de capteurs de monoxyde de carbone et éventuellement de capteurs de chaleur de la présente Norme européenne.
Les détecteurs ponctuels combinant l’utilisation de capteurs de fumée, de capteurs de monoxyde de carbone et éventuellement de capteurs de chaleur possédant des caractéristiques particulières adaptées à la détection de risques d’incendie spécifiques ne sont pas pris en compte dans la présente Norme européenne. Les exigences de performance relatives à toute autre fonction ne relèvent pas du domaine d’application de la présente norme (par exemple, des caractéristiques supplémentaires ou une fonctionnalité améliorée pour lesquelles la présente Norme européenne ne définit pas d’essai ou de méthode d’évaluation).

Sistemi za odkrivanje in javljanje požara ter alarmiranje - 31. del: Večsenzorski javljalniki  požara - Kombinirani točkovni javljalniki požara s senzorji za zaznavanje dima, ogljikovega monoksida in izbrane toplote

Ta evropski standard določa zahteve, preskusne metode in merila učinkovitosti za točkovne večsenzorske javljalnike požara za uporabo v sistemih za odkrivanje in javljanje požara, nameščenih v stavbah (glej EN 54-1:1996), ki v enem mehanskem ohišju vsebujejo najmanj en optični ali ionizacijski senzor za zaznavanje dima in vsaj en senzor za zaznavanje ogljikovega monoksida (CO) ter izbirno en ali več senzorjev toplote. Skupna učinkovitost odkrivanja požara se določi z uporabo kombinacije odkritih pojavov.
Ta evropski standard določa vrednotenje skladnosti (EoC) in označevanje zadevnih izdelkov (tj. večsenzorskih javljalnikov požara).
Večsenzorski javljalniki požara s posebnimi lastnostmi, primernimi za odkrivanje posebnih tveganj za nastanek požara, niso zajeti v tem standardu. Zahteve glede učinkovitosti za katere koli dodatne funkcije se v tem standardu ne obravnavajo (npr. dodatne funkcije ali izboljšana funkcionalnost, za katero ta standard ne določa preskusne ali ocenjevalne metode).
OPOMBA Nekatere vrste javljalnikov vsebujejo radioaktivne materiale. Nacionalne zahteve za zaščito pred sevanjem se razlikujejo po posameznih državah in niso določene v tem standardu.
