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 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.

Introduction

This document deals with passive infrared 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

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 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 document contains limited requirements for Grade 4 detectors. Future revisions of

the document 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.

1 Scope

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.

This permits two methods of signalling a masking: either by the intrusion signal and fault signal, or by a

dedicated masking or message. Use of the intrusion signal and fault signal is preferable, as this requires

fewer connections between CIE and detector. If multiple events overlap there will be some signal

combinations that could be ambiguous. To overcome this ambiguity it is suggested that detectors should

not signal ‘intrusion‘ and ‘fault‘ at the same time except to indicate masking. This implies that the detector

should prioritize signals, e.g. 1 Intrusion, 2 Fault, 3 Masking.

When, in Table 1, an event may optionally generate signals or messages, they shall be as shown in this

table.
An independent signal or message may be provided instead.
Total loss of Power Supply does not apply for message based detectors.
4.2 Detection
4.2.1 Detection performance

The detector shall generate an intrusion signal or message when the standard or simulated walk-test

target moves at velocities and attitudes specified in Table 3. For detection across the boundary the walk-

test distance shall be 1,5 m either side of the boundary. For test “Detection within the boundary” the

walk-test distance shall be 3,0 m.

For grade 3 and 4 detectors, the intermittent movement shall consist of the SWT walking 1 m at a velocity of

1,0 ms then pausing for 5 s before continuing. The sequence shall be maintained until the SWT has traversed

through the entire detection area. This constitutes one walk test. The test shall be repeated in each of the

directions shown in Figure C.3.

The detector shall provide an intrusion signal or message either during the walk test or within 10 s of its

completion

The detection performance tests required for a detector will depend on the coverage angle claimed.

Therefore this document differentiates between detectors with coverage angles less than or equal to

180°, such as those typically used for wall mounted applications, and detectors with coverage angles of

360° detectors intended for ceiling mounting.
4.2.2 Indication of detection

An indicator shall be provided at the detector to indicate when an intrusion signal or message has been

generated.

At grades 1 and 2 this indicator shall be capable of being enabled and disabled either remotely at Access

Level 2 and/or locally after removal of a cover which provides tamper detection as described in Tables

1 and 4.

At grades 3 and 4 this indicator shall be capable of being enabled and disabled remotely at Access

Level 2. It is permissible to also have local means to enable / disable the indicator (after removal of a

152 Introduction

153 This document deals with passive infrared detectors (to be referred to as the detector) used as part of

154 intrusion alarm systems installed in buildings. It includes four security grades and four environmental

155 classes.

156 The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to

157 analyse the resulting signals and to provide the necessary range of signals or messages to be used by

158 the rest of the intrusion alarm system.

159 The number and scope of these signals or messages will be more comprehensive for systems that are

160 specified at the higher grades.

161 This version of the document contains limited requirements for Grade 4 detectors. Future revisions of

162 the document are expected to include enhanced requirements for Grade 4 detectors.

163 This document is only concerned with the requirements and tests for the detector. Other types of

164 detector are covered by other documents identified as in the EN 50131-2 series.

165 1 Scope

166 This document is for passive infrared detectors installed in buildings and provides for security grades 1

167 to 4 (see EN 50131-1), specific or non-specific wired or wire-free detectors, and uses environmental

168 classes I to IV (see EN 50130-5). This document does not include requirements for detectors intended

169 for use outdoors.

170 The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to

171 analyse the resulting signals and to provide the necessary range of signals or messages to be used by

172 the rest of the intrusion alarm system.

173 The grade-dependent requirements of this document apply and it is essential that a detector fulfils all

174 the requirements of the specified grade.

175 Functions additional to the mandatory functions specified in this document can be included in the

176 detector, providing they do not influence the correct operation of the mandatory functions.

177 Requirements for system interconnections are not included in this document.

This permits two methods of signalling a masking: either by the intrusion signal and fault signal, or by a

dedicated masking or message. Use of the intrusion signal and fault signal is preferable, as this requires

fewer connections between CIE and detector. If multiple events overlap there will be some signal

combinations that could be ambiguous. To overcome this ambiguity it is suggested that detectors should

not signal ‘intrusion‘ and ‘fault‘ at the same time except to indicate masking. This implies that the detector

should prioritize signals, e.g. 1 Intrusion, 2 Fault, 3 Masking.

When, in Table 1, an event may optionally generate signals or messages, they shall be as shown in this

table.
An independent signal or message may be provided instead.
Total loss of Power Supply does not apply for message based detectors.
247 4.2 Detection
248 4.2.1 Detection performance

249 The detector shall generate an intrusion signal or message when the standard or simulated walk-test

250 target moves at velocities and attitudes specified in Table 3. For detection across the boundary the walk-

251 test distance shall be 1,5 m either side of the boundary. For test “Detection within the boundary” the

252 walk-test distance shall be 3,0 m.

For grade 3 and 4 detectors, the intermittent movement shall consist of the SWT walking 1 m at a velocity of

1,0 ms then pausing for 5 s before continuing. The sequence shall be maintained until the SWT has traversed

through the entire detection area. This constitutes one walk test. The test shall be repeated in each of the

directions shown in Figure C.3.

The detector shall provide an intrusion signal or message either during the walk test or within 10 s of its

completion

254 The detection performance tests required for a detector will depend on the coverage angle claimed.

255 Therefore this document differentiates between detectors with coverage angles less than or equal to

256 180°, such as those typically used for wall mounted applications, and detectors with coverage angles of

257 360° detectors intended for ceiling mounting.
258 4.2.2 Indication of detection

259 An indicator shall be provided at the detector to indicate when an intrusion signal or message has been

260 generated. At grades 1 and 2 this indicator shall be capable of being enabled and disabled either

261 remotely at Access Level 2 and/or locally enabled/disabled after removal of a cover which provides

262 tamper detection as described in Tables 1 and 4. At grades 3 and 4 this indicator shall be capable of

263 being enabled and disabled remotely at Access Level 2.
