Alarm systems - Intrusion and hold-up systems - Part 2-4: Requirements for combined passive infrared and microwave detectors
This document is for combined passive infrared and microwave 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 emit microwave signals and analyse the signals that are returned and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system. For a combined detector where both detection technologies need to be in their activated state in order to generate an alarm condition, the grade-dependent requirements of this document apply. For combined detectors which can be configured or operated such that each detection technology can generate an alarm condition independently, the grade-dependant requirements as defined in EN 50131 2 2 and EN 50131-2-3 apply, when configured accordingly. Otherwise, it is the responsibility of the manufacturer to clearly state that the detector does not comply to this document and not to EN 50131-2-2 and EN 50131 2-3 when put into such a configuration. 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 2-4: Exigences pour détecteurs combinés à infrarouges passifs et à hyperfréquences
Le présent document concerne les détecteurs à infrarouges passifs installés dans les immeubles et est prévu pour les grades de sécurité 1 à 4 (voir l’EN 50131-1), les détecteurs filaires ou non filaires spécifiques ou non spécifiques, et l'utilisation des classes d'environnement I à IV (voir l’EN 50130-5). Le présent document ne comprend pas d’exigences pour les détecteurs destinés à une utilisation extérieure. Le détecteur a pour objet de détecter les rayonnements infrarouges émis par un intrus dans un spectre étendu, d’émettre des signaux en hyperfréquences et d’analyser les signaux renvoyés, ainsi que de fournir l’ensemble des signaux ou messages nécessaires à utiliser par le reste du système d’alarme intrusion. Pour un détecteur combiné où il est nécessaire que les deux technologies de détection se trouvent dans leur état activé en vue de générer une condition d’alarme, les exigences dépendantes du grade du présent document s’appliquent. Pour les détecteurs combinés qui peuvent être configurés pour fonctionner de telle sorte que chaque technologie de détection peut générer une condition d’alarme indépendamment, les exigences dépendantes du grade telles que définies dans l’EN 50131 2 2 et l’EN 50131-2-3 s’appliquent lorsqu’ils sont configurés en conséquence. Le cas contraire, il est de la responsabilité du fabricant d’indiquer clairement que le détecteur n’est conforme ni au présent document, ni à l’EN 50131-2-2 et à l’EN 50131 2-3 lorsqu’il est mis dans une telle configuration. Il est essentiel qu'un détecteur satisfasse à toutes les exigences du grade spécifié. Des fonctions complémentaires aux fonctions obligatoires spécifiées dans le présent document peuvent être incluses dans le détecteur, sous réserve qu'elles n'influencent pas le bon fonctionnement des fonctions obligatoires. Les exigences relatives aux interconnexions des systèmes ne sont pas incluses dans le présent document.

Introduction
This document deals with combined passive infrared and microwave detectors (to be referred to as the
detector) used as part of intrusion alarm systems installed in buildings. It includes four security grades
and four environmental classes.
The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to
emit microwave signals and analyse the signals that are returned and to provide the necessary range
of signals or messages to be used by the rest of the intrusion alarm system.
The number and scope of these signals or messages will be more comprehensive for systems that are
specified at the higher grades.
This version of the standard contains limited requirements for Grade 4 detectors. Future revisions of the
standard are expected to include enhanced requirements for Grade 4 detectors.
This document is only concerned with the requirements and tests for the detector. Other types of
detector are covered by other documents identified as in the EN 50131-2 series.
NOTE Each country has certain regulations in regards to which part of the microwave spectrum is allowed to
be used in this application. This information can be found in ERC recommendation 70-03.
