Introduction
This Technical Specification is a specification for combined passive infrared and microwave detectors (to
be referred to here as the combined 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 the combined detector is to detect the broad spectrum infrared radiation emitted by an
intruder and, at the same time, to emit microwave radiation over the area being protected, and analyse
signals that are returned. An intrusion signal or message is only generated when both technologies
register a positive indication of the presence of an intruder, thus reducing incorrect operation. The
combined detector shall provide the necessary range of signals or messages to be used by the rest of the
intrusion detection system.
The number and scope of these signals or messages will be more comprehensive for systems that are
specified at the higher grades.
If a combined detector can be operated in each technology individually, it shall also meet the grade
dependent requirements of the standards having relevance to those technologies.
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 combined passive infrared and microwave detectors, and is covered by 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 shall be provided at the detector to indicate when detection causes an intrusion signal or
message. This indicator shall only have this function, shall not function in the event of power failure, and
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 equipment.
4.2.3 Significant reduction of specified range
If the facility to detect reduction in specified range is provided, then range reduction along the
principal axis of detection of more than 50 % shall generate an alarm or fault signal or message
within a maximum period of 180 s, according to the requirements given in Table 2. The
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
NOTE 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 signals
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 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 it’s previous state within 5 s. Fault indication requirements appear in
Table 1.

CLC/TS 50131-2-4:2004 - 10 -
Where normal operation of the detector is inhibited during a local test of function monitoring the inhibition
time shall be limited to a maximum of 15 s in a period of 1 h.
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 an intrusion signal or message when air is blown
over the face of the detector.
4.4.2 Immunity to visible & near infrared radiation
The PIR component of the detector shall not generate an intrusion signal or message when visible and
near infrared radiation from a light source such as a car headlamp is directed on to the front window or
lens through a pane of glass.
4.4.3 Immunity to microwave signal interference by fluorescent lights
The microwave component of the detector shall not generate an intrusion signal or message due to the
operation of a fluorescent light source mounted nearby.
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 must 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 of adjustable mountings
Where the orientation of a detector can be adjusted, resistance to re-orientation of the mounting 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 M.
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 detection device.
