Alarm systems - Intrusion and hold-up systems - Part 2-2: Requirements for passive infrared detectors

This document is for passive infrared detectors installed in buildings and provides for security grades 1 to 4 (see EN 50131 1), specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV (see EN 50130 5). This document does not include requirements for detectors intended for use outdoors. The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to analyse the resulting signals and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system. The grade-dependent requirements of this document apply and it is essential that a detector fulfils all the requirements of the specified grade. Functions additional to the mandatory functions specified in this document can be included in the detector, providing they do not influence the correct operation of the mandatory functions. Requirements for system interconnections are not included in this document.

Systèmes d'alarme - Systèmes d'alarme contre l'intrusion et les hold-up - Partie 2-2: Exigences pour détecteurs à infrarouges passifs

Le présent document concerne les détecteurs à infrarouges passifs installés dans les immeubles. Il est prévu pour les détecteurs filaires ou non filaires spécifiques ou non spécifiques des grades de sécurité 1 à 4 (voir l’EN 50131 1) et utilise des classes d’environnement I à IV (voir l’EN 50130 5). Le présent document ne contient pas d’exigences pour les détecteurs à infrarouges passifs destinés à une utilisation en extérieur. Le détecteur est destiné à détecter les rayonnements infrarouges émis par un intrus dans un spectre étendu, à analyser les signaux résultants et à fournir la plage nécessaire des signaux ou messages à utiliser par le reste du système d’alarme contre l’intrusion. Les exigences en fonction du grade indiquées dans le présent document s’appliquent, et il est essentiel qu’un détecteur satisfasse à toutes les exigences du grade spécifié. Des fonctions supplémentaires aux fonctions obligatoires spécifiées dans le présent document peuvent être incluses dans le détecteur, sous réserve qu’elles n’aient pas d’impact sur le bon fonctionnement des fonctions obligatoires. Les exigences concernant les interconnexions du système ne sont pas contenues dans le présent document.

Alarmni sistemi - Sistemi za javljanje vloma in ropa - 2-2. del: Zahteve za pasivne infrardeče javljalnike

Ta dokument se uporablja za pasivne infrardeče javljalnike, ki so nameščeni v zgradbah, določa varnostne razrede od 1 do 4 (glej EN 50131-1) in lastnosti specifičnih oziroma nespecifičnih kabelskih ali brezžičnih javljalnikov ter uporablja okoljske razrede od I do IV (glej EN 50130-5). Ta dokument ne zajema zahtev za javljalnike, namenjene za zunanjo uporabo.
Namen javljalnika je zaznati infrardeče sevanje širokega spektra, ki ga oddaja vsiljivec, analizirati nastale signale in zagotoviti potreben obseg signalov ali sporočil, ki jih uporablja preostali del sistema za javljanje vloma.
Zahteve javljalnika, ki veljajo v tem dokumentu, so odvisne od razreda, pri čemer je bistveno, da javljalnik izpolnjuje vse zahteve določenega razreda.
Poleg obveznih funkcij, ki so opredeljene v tem dokumentu, ima lahko javljalnik tudi dodatne funkcije, pri čemer te ne smejo vplivati na pravilno delovanje obveznih funkcij.
Zahteve za medsebojne sistemske povezave niso vključene v ta dokument.
