Introduction
This Technical Specification is a specification for passive infrared detectors (to be referred to as
the detector) used as part of intrusion detection systems installed in buildings. It includes four
security grades and the first three 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 intruder
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 specification is only concerned with the requirements and tests for the detector. Other types
of detector are covered by other documents identified as CLC/TS 50131-2-x.
The requirement in EN 50131-1 that detectors in grade 3 and 4 systems shall include a 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.
1 Scope
This Technical Specification 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 III (see EN 50130-5).
A function designated in the specification as not required for a particular grade may be provided
by the manufacturer. If provided, it will be tested, and shall meet all relevant requirements of any
higher grade. If it passes, the manufacturer may claim it as an extra feature, which does not alter
the overall grading of the detector.
The specification does not apply to system interconnections.

4.2.2 Indication of detection
An indicator, if provided at the detector, shall indicate when detection causes an intrusion signal
or message. This indicator shall be capable of being enabled/disabled. This operation shall only
be performed locally after removal of the cover or remotely at the control and indicating

requirements of 4.3.5 (self test) and 4.5.5 (resistance to masking) can provide range reduction
detection.
If additional equipment is required to detect significant reduction in range, reference shall be
made to the manufacturer’s documentation.

4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages
Wired detectors 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. Wire free detectors shall perform the same
function in a time as follows:
Grade 1: 300 s,
Grade 2: 300 s,
Grade 3: 30 s,
Grade 4: 15 s (see EN 50131-1 for amendment).
4.3.2 Switch on delay
The detector shall meet all functional requirements within 180 s of the power supply reaching its
nominal voltage.
4.3.3 Fault condition signalling
When a detector suffers a fault, a fault signal or message shall be generated in accordance with
the manufacturer's specification, and the provisions of Table 1.
4.3.4 Power supply faults
Detectors of all grades shall signal complete power failure according to the provisions of Table 1.
Additionally, detectors of grades 3 and 4 shall signal when the supply voltage moves below the
manufacturer’s specified range according to the provisions of Table 1.
4.3.5 Self tests
Grade 3 and grade 4 detectors shall monitor the function of the sensor and associated on-board
signal processing circuitry. A self-test shall be performed under the control of the detector.
When a remote self-test is initiated, a signal or message shall be generated between 1 s and 5 s
later, and shall be signalled within 5 s of that initiation. The test duration shall not exceed 10 s.
After the test is completed, the detector shall resume its previous state within 5 s. Fault indication
requirements appear in Table 1.
Where normal operation of the detector is inhibited during a local test of function monitoring the
detector inhibition time shall be limited to a maximum of 15 s in a period of 1 h.
4.4 Immunity 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 detector shall not generate any signal or message when air is blown over the face of the
detector.
4.4.2 Immunity to visible and near infrared radiation
The detector shall not generate any signal or message when visible and near Infrared radiation

4.5 Tamper security
Tamper security requirements for each grade of detector are shown in Table 3.
4.5.1 Prevention of unauthorized access to the inside of the detector through covers and
existing holes
Access holes shall not allow interference with the operation of the detector by probing with
commonly available tools. Damage shall not be caused that would be visible to a person with
normal eyesight viewing from a distance of 1 m with the detector illuminated at a level of
2 000 lux.
A tool shall be required to open the unit. All covers giving access to components which could
affect adversely the operation of the detector shall be fitted with a tamper detection device in
accordance with Table 3. A tamper signal or message shall be generated before access is gained
with any tool.
4.5.2 Detection of removal from the mounting surface
A tamper detection device shall be fitted which signals a tamper if the detector is removed from
the mounting surface, in accordance with Table 3. Mounting screws shall only be accessible from
within the unit. Operation of the device shall not be preventable by external means. This device
shall activate before access can be gained to it.
4.5.3 Resistance to re-orientation
Where the orientation of a detector can be adjusted, resistance to re-orientation shall be provided
in accordance with Table 3.
The alignment of the boundary of detection shall not have changed by more than 5° due to a
grade dependent applied torque. Alternatively a tamper detection device shall signal before the
alignment of the boundary of detection has moved by 5°. One test arrangement is described in
Annex L.
If a detector provides a means to adjust the orientation of its coverage pattern, the access to this
means shall be protected by a tamper device.
4.5.4 Immunity to magnetic field interference
It shall not be possible to inhibit any output or signalling devices with a magnet of grade
dependent remanence, according to Table 3. The form of standard magnets shall be as described
in Annex A.
4.5.5 Resistance to masking
Means shall be provided to detect inhibition of the operation of the detector by covering its
sensing area and sensor, in the unset mode. The maximum response time for the masking
detection device shall be 180 s. Intrusion and fault signals or messages or a dedicated anti-
masking signal or message shall be generated. The signals or messages shall remain latched
until restored. Grade dependency appears in Table 3.
No anti-masking signal or message shall be generated by normal human movement at 1 m/s at a
distance greater than 1 m in the unset condition.
