Introduction
This Technical Specification is a specification for combined passive infrared and ultrasonic 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 a combined 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. 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.
This specification is only concerned with the requirements and tests for the combined detector. Other
types of detector are covered by other documents identified as drafts in the EN 50131-2 series.
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 (see 4.2.3) or
by suitable system design.

1 Scope
This Technical Specification provides for security grades 1 - 4 (see EN 50131-1), specific or non-specific
wired or wire-free combined passive infrared and ultrasonic detectors, and is covered by environmental
classes 1 – 3 (see EN 50130-5).
A function designated in the specification as not required for a particular grade may be provided by
themanufacturer. 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.

4.2.3 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
manufacturers documentation.
4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages
Wired combined 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 combined 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 combined 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 combined 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
Combined detectors of all grades shall signal complete power failure according to the provisions of
Table 1.
Additionally, combined detectors of grades 3 and 4 shall signal when the supply voltage moves below the
manufacturers specified range according to the provisions of Table 1.
4.3.5 Self tests
Grade 3 and grade 4 combined 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 combined
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 combined detector shall resume it’s previous state within 5 s. Fault indication requirements
appear in Table 1
Where normal operation of the combined 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 combined 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.

– 11 – CLC/TS 50131-2-5:2004
4.4.1 Immunity to air flow
The PIR component of the combined detector shall not generate an intrusion signal or message when air
is blown over the face of the combined detector.
4.4.2 Immunity to visible and near infrared radiation
The PIR component of the combined 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 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 combined detector are shown in Table 3.
4.5.1 Prevention of unauthorised access to the inside of the combined detector through covers
and existing holes
Access holes shall not allow interference with the operation of the combined 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 combined 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 combined 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 combined 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 combined 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°.
If a combined 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.
4.5.4 Immunity to magnetic field interference
It shall not be possible to inhibit any signalling devices with a magnet of grade dependent remanence,
according to Table 3. The form of standard magnets is 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 shall be generated by normal human movement at 1 m/s at a distance greater
than 1 m in the unset condition.
