Introduction

This European Standard 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 a detector is to detect the broad spectrum infrared radiation emitted by an intruder 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 European Standard is only concerned with the requirements and tests for the passive infrared

detectors. Other types of detectors are covered by other documents identified as in EN 50131-2

series.

An independent signal or message may be provided instead.

This permits two methods of signalling a masking or reduction of range event: either by

the intrusion signal and fault signal, or by a dedicated masking or reduction of range

signal 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 may 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 prioritise signals, e.g. 1

Intrusion, 2 Fault, 3 Masking.
Alternatively Total loss of Power Supply shall be determined by loss of
communication with the detector.

When, in Table 1, an event may optionally generate signals or messages, they need to

be as shown in this table.
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 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-1 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 means to detect a significant reduction in range may be met either by detectors having the appropriate

function (4.2.3) or by suitable system design. Two or more devices (e.g. a detector in conjunction with a

camera, active transmitter or additional detector), may cooperate and interconnect with the system to provide

means to detect a significant reduction of range.
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 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.
4.2.3 Significant reduction of range

Grade 4 detectors shall detect significant reduction of range or coverage area due, for example, to

deliberate or accidental introduction of objects or obstructions into the coverage area.

Range reduction along the principal axis of detection of more than 50 % shall generate a signal or

message within 180 s, according to the requirements of Table 2 and Table 3.

The signals or messages shall remain for at least as long as the significant reduction of range

condition is present. A significant reduction of range signal or message shall not be reset while the

significant reduction of range condition is still present. Alternatively the significant reduction of range

---------------------- Page: 13 ----------------------
SIST EN 50131-2-2:2018
EN 50131-2-2:2017 (E)

signal or message shall be generated again within 180 s of being reset if the significant reduction of

range condition is still present.

If additional equipment is required to detect significant reduction of range, reference shall be made to

this equipment and its operation in the manufacturer’s documentation.
4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages

Detectors using wired interconnections shall be able to provide an intrusion signal or message not

more than 15 s after the end of the preceding intrusion signal or message.

Detectors using wire free interconnections shall be able to provide an intrusion signal or message after

the end of the preceding intrusion signal or message within the following times:
Grade 1 300 s
Grade 2 180 s
Grade 3 30 s
Grade 4 15 s
4.3.2 Switch on delay

The detector shall meet all functional requirements within 180 s of the power supply reaching its

nominal voltage as specified by the manufacturer.
4.3.3 Self-tests
4.3.3.1 General

Self-tests shall detect failures of a critical function (e.g. unable to detect temperature differences) and

signal these situations according to Table 2.
4.3.3.2 Local self-test

The detector shall automatically test itself at least once every 24 h according to the requirements of

Tables 1 and 2. If normal operation of the detector is inhibited during a local self-test, the detector

inhibition time shall be limited to a maximum of 30 s in any period of 2 h.
4.3.3.3 Remote self-test

A detector shall process remote self-tests and generate signals or messages in accordance with

Tables 1 and 2 within 10 s of the remote self-test signal being received, and shall return to normal

operation within 30 s of the remote test signal being received.
4.4 Immunity to incorrect operation
4.4.1 General

The detector shall be considered to have sufficient immunity to incorrect operation if the following

requirements have been met. No intrusion signal or message shall be generated during the tests.

4.4.2 Immunity to air flow

The detector shall not generate any signal or message when air is blown over the face of the detector.

4.4.3 Immunity to visible and near infrared radiation

The detector shall not generate any signal or message when a car headlamp is swept across the front

window or lens through two panes of glass.

4.5 Tamper security
4.5.1 General
Tamper security requirements for each grade of detector are shown in Table 4.

4.5.2 Resistance to and detection of unauthorised access to components and means of

adjustment

All components, means of adjustment and access to mounting screws, which, when interfered with,

could adversely affect the operation of the detector, shall be located within the detector housing. Such

access shall require the use of an appropriate tool and depending on the grade as specified in Table 4

shall generate a tamper signal or message before access can be gained.

It shall not be possible to gain such access without generating a tamper signal or message or causing

visible damage.
4.5.3 Detection of removal from the mounting surface

A tamper signal or message shall be generated if the detector is removed from its mounting surface, in

accordance with Table 4.
4.5.4 Resistance to, or detection of, re-orientation

After the torque given in Table 4 has been applied and removed from the detector it shall not have

rotated more than 5° from its original position. Alternatively, when the torque given in Table 4 is

applied, a tamper signal or message shall be generated if the detector rotates by more than 5°.

4.5.5 Immunity to magnetic field interference

It shall not be possible to inhibit any signals or messages with a magnet of grade dependence

according to Table 4. The magnet types shall be as described in Annex A.
4.5.6 Detection of masking

Means shall be provided to detect inhibition of the operation of the detector by masking according to

the requirements of Table 4.

The maximum response time for the masking detection device shall be 180 s. Masking shall be

signalled according to the requirements of Table 2. The signals or messages shall remain for at least

as long as the masking condition is present. A masking signal or message shall not be reset while the

masking condition is still present. Alternatively the masking signal or message shall be generated

again within 180 s of being reset if the masking condition is still present.

NOTE From a system design point of view it would be preferable for masked detectors to automatically reset

after the masking condition is removed.

No masking signal or message shall be generated by normal human movement according to Figure

C.6.

For detectors where detection of masking may be remotely disabled the detection of masking shall

operate when the I&HAS is unset; it is not required to operate when the I&HAS is set.
