SIST EN 54-31:2015+A1:2016

Fire detection and fire alarm systems - 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 and fire alarm systems installed in and around buildings (see EN 54 1:2011), 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, utilizing the combination of the detected phenomena. This European Standard covers only modes of operation, where at least the signals of both smoke and carbon monoxide sensors are continuously evaluated.
This European Standard provides for the assessment and verification of constancy of performance (AVCP) of point detectors using a combination of smoke, carbon monoxide and optionally heat sensors to this EN.
Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors, which are 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 standard (e.g. additional features or enhanced functionality for which this European Standard does not define a test or assessment method).

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 Brandmelde- und Feueralarmanlagen in und um Gebäude eingesetzt werden (siehe EN 54 1:2011) 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, welche die Kombination der erkannten Brandphänomene nutzen. Diese Norm gilt nur für Betriebsarten, bei denen mindestens die Signale von sowohl Rauch- als auch Kohlenmonoxidmeldern kontinuierlich bewertet werden.
Diese Europäische Norm enthält die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) von punktförmigen Mehrfachsensor-Brandmeldern mit kombinierten Rauch- und CO-Sensoren und optionalen Wärmesensoren nach dieser EN.
Punktförmige Melder mit kombinierten Rauch- und CO-Sensoren und optionalen Wärmesensoren 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).

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 ter sistemih požarnega alarma, nameščenih v stavbah (glej EN 54 1:2011), 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 poljubno število senzorjev toplote z uporabo kombinacije zaznanih pojavov. Ta evropski standard zajema samo načine delovanje, pri katerih se nenehno ocenjujejo vsaj signali senzorjev za dim in ogljikov monoksid.
Ta evropski standard določa zahteve glede ocenjevanja in preverjanja nespremenljivosti delovanja (AVCP) točkovnih detektorjev na podlagi kombinacije senzorjev za dim, ogljikov monoksid in izbirno tudi toploto glede na ta EN.
Točkovni detektorji, ki uporabljajo kombinacijo senzorjev za dim, ogljikov monoksid in izbirno tudi toploto ter imajo posebne lastnosti, ustrezne za zaznavanje posebnih tveganj požara, niso zajeti v tem evropskem standardu. Zahteve glede učinkovitosti za katere koli dodatne funkcije se v tem standardu ne obravnavajo (npr. dodatne funkcije ali izboljšana funkcionalnost, za katero ta evropski standard ne določa preskusne ali ocenjevalne metode).
