Introduction
This European Standard is for combined passive infrared and ultrasonic 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, at the same time, to emit ultrasonic radiation over the area being protected, and analyse signals
that are returned, 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 detector. Other
types of detector are covered by other documents identified as EN 50131-2 series.

1 Scope
This European Standard is for combined passive infrared and ultrasonic 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 standard does not
include requirements for combined passive infra red and ultrasonic detectors intended for use
outdoors.
A detector shall fulfil all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this standard may be included in the
detector, providing they do not influence the correct operation of the mandatory functions.
The European Standard does not apply to system interconnections.

NOTE 1 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.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages, they shall be
as shown in this table.
NOTE 3 It is accepted that a bus system may send out dedicated signals or messaged and does
not necessarily have to follow the mapping of Table 2 provided that all of the required events are
signalled.
a
An independent signal or message may be provided instead.
b
Alternatively total loss of power supply shall be determined by loss of communication with the
detector.

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

For grades 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.
b
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 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.

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.
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 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.
4.3.3.2 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 of the individual technologies to incorrect operation
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.
4.4.1 Immunity to air flow
The PIR component of the detector shall not generate any signal or message when air is blown over
the face of the detector.
---------------------- Page: 12 ----------------------
SIST EN 50131-2-5:2009
– 11 – EN 50131-2-5:2008
4.4.2 Immunity to visible and near infrared radiation
The PIR component of 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.
4.4.3 Immunity to ultrasonic signal interference by extraneous sound sources
The ultrasonic component of the combined detector shall not generate an intrusion signal or message
due to the operation of a sound source mounted nearby.
4.5 Tamper security
Tamper security requirements for each grade of detector are shown in Table 4.
4.5.1 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.
4.5.2 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.
4.5.3 Resistance to, or detection of, re-orientation
When the torque given in Table 4 is applied to the detector it shall not rotate more than 5°.
Alternatively, when the torque given in Table 4 is applied, a tamper signal or message shall be
generated before the detector has rotated by 5°.
4.5.4 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.
4.5.5 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.
-1
No masking signal or message shall be generated by normal human movement at 1 ms at a distance
equal to or greater than 1 m.
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.

Introduction
This European Standard is for combined passive infrared and ultrasonic 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, at the same time, to emit ultrasonic radiation over the area being protected, and analyse signals
that are returned, 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 detector. Other
types of detector are covered by other documents identified as EN 50131-2 series.

1 Scope
This European Standard is for combined passive infrared and ultrasonic 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 standard does not
include requirements for combined passive infra red and ultrasonic detectors intended for use
outdoors.
A detector shall fulfil all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this standard may be included in the
detector, providing they do not influence the correct operation of the mandatory functions.
The European Standard does not apply to system interconnections.

NOTE 1 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.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages, they shall be
as shown in this table.
NOTE 3 It is accepted that a bus system may send out dedicated signals or messaged and does
not necessarily have to follow the mapping of Table 2 provided that all of the required events are
signalled.
a
An independent signal or message may be provided instead.
b
Alternatively total loss of power supply shall be determined by loss of communication with the
detector.

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 grades 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.
b
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 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.
---------------------- Page: 10 ----------------------
EN 50131-2-5:2008 – 10 –
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.
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 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.
4.3.3.2 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 of the individual technologies to incorrect operation
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.
4.4.1 Immunity to air flow
The PIR component of the detector shall not generate any signal or message when air is blown over
the face of the detector.
---------------------- Page: 11 ----------------------
– 11 – EN 50131-2-5:2008
4.4.2 Immunity to visible and near infrared radiation
The PIR component of 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.
4.4.3 Immunity to ultrasonic signal interference by extraneous sound sources
The ultrasonic component of the combined detector shall not generate an intrusion signal or message
due to the operation of a sound source mounted nearby.
4.5 Tamper security
Tamper security requirements for each grade of detector are shown in Table 4.
4.5.1 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.
4.5.2 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.
4.5.3 Resistance to, or detection of, re-orientation
When the torque given in Table 4 is applied to the detector it shall not rotate more than 5°.
Alternatively, when the torque given in Table 4 is applied, a tamper signal or message shall be
generated before the detector has rotated by 5°.
4.5.4 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.
4.5.5 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.
-1
No masking signal or message shall be generated by normal human movement at 1 ms at a distance
equal to or greater than 1 m.
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.
