FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

INTRODUCTION
This part 2-4 of the IEC 62642 series of standards gives requirements for passive infrared and
microwave detectors used in intrusion and hold-up alarm systems. The other parts of this
series of standards are as follows:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors

Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices/systems
This standard deals with combined passive infrared and microwave 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 the detector is to detect the broad spectrum infrared radiation emitted by an
intruder, to emit microwave radiation and analyse signals that are returned 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 International Standard is only concerned with the requirements and tests for the detector.
Other types of detector are covered by other documents identified as in IEC 62642-2 series.
If a combined detector can be operated in each technology individually, it also meets the
grade-dependant requirements of the standards having relevance to those technologies.

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, eg 1 Intrusion,
2 Fault, 3 Masking.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages, they
areas 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
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 (eg 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 specified 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.
– 12 – 62642-2-4 Ó IEC:2010
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 signals or messages when air is
blown over the face of the detector.
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 microwave signal interference by fluorescent lights
The microwave component of the detector shall not generate any signals or messages 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 4.
62642-2-4 Ó IEC:2010 – 13 –
4.5.1 Resistance to and detection of unauthorised access to the inside of the
detector through covers and existing holes
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.

The tests are intended to be primarily concerned with verifying the correct operation of the
detector to the specification provided by the manufacturer. All the test parameters specified
shall carry a general tolerance of ± 10 % unless otherwise stated. A list of tests appears as a
general test matrix in Annex B.
6.1 General test conditions
6.1.1 Standard conditions for testing
The general atmospheric conditions in the measurement and tests laboratory shall be those
specified in IEC 60068-1, 5.3.1, unless stated otherwise.
Temperature 15 °C to 35 °C
Relative humidity 25 % RH to 75 % RH
Air pressure 86 kPa to 106 kPa
6.1.2 General detection testing environment and procedures
Manufacturer’s documented instructions regarding mounting and operation shall be read and
applied to all tests.
6.1.3 Testing environment
The detection tests require an enclosed, unobstructed and draught-free area that enables
testing of the manufacturer’s claimed coverage pattern. The test area shall be large enough
so as not to significantly affect the microwave coverage pattern due to reflections.
The test area walls and floor shall have a recommended emissivity of at least 80 % between
8 mm and 14 mm wavelength, at least directly behind the SWT.
The temperature of the background surface immediately behind the SWT shall be in the range
15 °C to 25 °C, and shall be horizontally uniform over that area to ± 2 °C. Over the whole
background area it shall be measured at ten points spread evenly throughout the coverage
pattern. The average background temperature is the linear average of the ten points.
Annex C provides example diagrams for the range of walk tests for one format of detection
pattern. Many others are possible.
6.1.4 Standard walk test target (SWT)
The SWT shall have the physical dimensions of 1,60 m to 1,85 m in height, shall weigh
70 kg ± 10 kg and shall wear close-fitting clothing having a recommended emissivity of at
least 80 % between 8 mm and 14 mm wavelength. No metallic objects shall be worn or carried
by the SWT or incorrect microwave reflection will result.
6.1.4.1 Standard walk test target temperature
Temperatures shall be measured at the following five points on the front of the body of the SWT:
1. Head
2. Chest
3. Back of hand
4. Knee
62642-2-4 Ó IEC:2010 – 17 –
5. Feet
Temperatures shall be measured using a non-contact thermometer or equivalent equipment.
The temperature differential at each body point is measured, then weighted and averaged as
detailed in D.1.
There shall be a means of calibration and control of the desired velocity at which the SWT is
required to move.
NOTE The use of a simulator/robot in place of the SWT is permitted, provided that it meets the specification of
the SWT with regard to temperature and microwave reflectivity. It is known as the simulated target. In case of
conflict, a human walk test is the primary reference.
6.1.4.2 Standard walk test target temperature differential
The walk tests shall be performed either with an average temperature differential Dt (as
r
calculated in D.1) of 3,5 °C ± 20 %, or if the temperature differential is larger than 3,5 °C
+ 20 % (4,2 °C), it may be adjusted to achieve an equivalent temperature differential Dte
within this range by one of the means specified in D.2.
If Dt is less than 3,5 °C – 20 % (2,8 °C), no valid test is possible.
r
If Dt is between 2,8 °C and 4,2 °C, no adjustment is required.
r
6.1.5 Testing procedures
The detector shall be mounted at a height of 2,0 m unless otherwise specified by the
manufacturer. The orientation shall be as specified by the manufacturer with unobstructed
view of the walk test to be performed. The detector shall be connected to the nominal supply
voltage, and connected to equipment with a means of monitoring intrusion signals or
messages. The detector shall be allowed to stabilise for 180 s. If multiple sensitivity modes
such as pulse counting are available, any non-compliant modes shall be identified by the
manufacturer. All compliant modes shall be tested.
6.2 Basic detection test
The purpose of the basic detection test is to verify that a detector is still operational after a
test or tests has/have been carried out. The basic detection test verifies only the qualitative
performance of a detector. The basic detection test is performed using the BDT(s).
6.2.1 Basic detection targets (BDT)
The manufacturer shall provide, for testing purposes only, methods for placing either
technology permanently in a state where the other technology may cause an intrusion signal
or message.
The passive infrared BDT consists of a heat source with heat emission equivalent to that of a
human hand, which can be moved across the field of view of the detector. An informative
description is given in Annex E. The temperature of the source shall be between 3,5 °C and
10,0 °C above the background.
The microwave BDT shall be a metal plate having equivalent microwave reflectivity to that of
the human hand, which can be moved across the field of view of the detector.
BDTs may be used separately or together.
A close-in walk test may be carried out as an alternative to using the BDT.
– 18 – 62642-2-4 Ó IEC:2010
6.2.2 PIR basic detection test
Activate the microwave technology; the unit shall not generate an intrusion signal or message.
A stimulus that is similar to that produced by the SWT is applied to the detector, using the PIR
BDT. Move the PIR BDT perpendicularly across the centre line of the detection field at a
distance of not more than 1 m, and at a height where the manufacturer claims detection will
occur.
–1 –1
Move the PIR BDT a distance of 1 m at a velocity of 0,5 ms to 1,0 ms . The detector shall
produce an intrusion signal or message when exposed to an alarm stimulus both before and
after being subjected to any test that may adversely affect its performance.
6.2.3 Microwave basic detection test
Activate the passive infrared technology; the unit shall not generate an intrusion signal or
message. A stimulus that is similar to that produced by the SWT is applied to the detector
using the microwave BDT. Move the microwave BDT along the centre line of the detection
field from a distance of 2 m to a distance of 1 m from the detector, at a height where the
manufacturer claims detection will occur.
–1 –1
The microwave BDT is to be moved a distance of 1 m at a velocity of 0,5 ms to 1,0 ms .
The detector shall produce an intrusion signal or message when exposed to the stimulus both
before and after being subjected to any test that may adversely affect its performance.
6.3 Walk testing
6.3.1 General walk test method
Walk testing is accomplished by the controlled movement of a SWT across the field of view of
the detector. The grade dependent velocities and attitudes to be used by the SWT are
specified in Table 3. The tolerance of these velocities shall be better than ± 10 %. The SWT
begins and ends a walk with feet together. Annex F is an informative description of two
systems that may be used to control and monitor the desired velocity.
6.3.2 Verification of detection performance
The general test conditions of 6.1.1, 6.1.2 and 6.1.3 shall apply to all tests in this series.
Detection performance shall be tested against the manufacturer’s documented claims.
Example walk test diagrams are shown in Annex C.
Any variable controls shall be set to the values recommended by the manufacturer to achieve
the claimed performance.
If the dimensions of the detection pattern exceed the available test space, it may be tested in
sections rather than as a whole.
The SWT or a suitable simulated target, with its temperature difference with the background
adjusted according to Annex D, shall be used. Grade dependent velocities and attitudes are
specified in Table 3.
6.3.3 Detection across and within the detection boundary.
The tests assess detection of intruders moving within and across the boundaries of the
detection area. The diagrams in Annex C show an example of the detection boundary,
superimposed where appropriate on a scaled 2 m squared grid. A variety of boundary formats
are possible and can be tested.
62642-2-4 Ó IEC:2010 – 19 –
6.3.3.1 Verify detection across the boundary
Figure C.1 shows an example of a manufacturer’s claimed detection boundary.
Place test points at 2 m intervals around the boundary of the detection pattern, starting from
the detector, and finishing where the boundary crosses the detector axis. Repeat for the
opposite side of the detection pattern. If the gap between the final point on each side is
greater than 2 m, place a test point where the boundary crosses the detector axis. For Grade
1 detectors it is only necessary to test alternate test points.
Each test point is connected to the detector by a radial line. At each test point, two test
directions into the detection coverage pattern are available at + 45° and – 45° to the radial
line. Both directions shall be tested beginning at a distance of 1,5 m from the test point, and
finish 1,5 m after it.
A walk test is a walk in one direction through a test point. Before commencing and after
completing each walk test, the SWT shall stand still for at least 20 s.
A walk test that generates an intrusion signal or message is a passed walk test. Alternatively
if the first walk test attempt does not generate an intrusion sig

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

INTRODUCTION
This part 2-4 of the IEC 62642 series of standards gives requirements for passive infrared and
microwave detectors used in intrusion and hold-up alarm systems. The other parts of this
series of standards are as follows:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / Microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / Ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency
techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices/systems
This standard deals with combined passive infrared and microwave 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 the detector is to detect the broad spectrum infrared radiation emitted by an
intruder, to emit microwave radiation and analyse signals that are returned 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 International Standard is only concerned with the requirements and tests for the detector.
Other types of detector are covered by other documents identified as in IEC 62642-2 series.
If a combined detector can be operated in each technology individually, it also meets the
grade-dependant requirements of the standards having relevance to those technologies.

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, eg 1 Intrusion,
2 Fault, 3 Masking.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages, they
areas 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
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 (eg 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 specified 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.

4.5.1 Resistance to and detection of unauthorised access to the inside of the
detector through covers and existing holes
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

6 Testing
The tests are intended to be primarily concerned with verifying the correct operation of the
detector to the specification provided by the manufacturer. All the test parameters specified
shall carry a general tolerance of ± 10 % unless otherwise stated. A list of tests appears as a
general test matrix in Annex B.
6.1 General test conditions
6.1.1 Standard conditions for testing
The general atmospheric conditions in the measurement and tests laboratory shall be those
specified in IEC 60068-1, 5.3.1, unless stated otherwise.
Temperature 15 °C to 35 °C
Relative humidity 25 % RH to 75 % RH
Air pressure 86 kPa to 106 kPa
6.1.2 General detection testing environment and procedures
Manufacturer’s documented instructions regarding mounting and operation shall be read and
applied to all tests.
6.1.3 Testing environment
The detection tests require an enclosed, unobstructed and draught-free area that enables
testing of the manufacturer’s claimed coverage pattern. The test area shall be large enough
so as not to significantly affect the microwave coverage pattern due to reflections.
The test area walls and floor shall have a recommended emissivity of at least 80 % between
8 mm and 14 mm wavelength, at least directly behind the SWT.
The temperature of the background surface immediately behind the SWT shall be in the range
15 °C to 25 °C, and shall be horizontally uniform over that area to ± 2 °C. Over the whole
background area it shall be measured at ten points spread evenly throughout the coverage
pattern. The average background temperature is the linear average of the ten points.
Annex C provides example diagrams for the range of walk tests for one format of detection
pattern. Many others are possible.
6.1.4 Standard walk test target (SWT)
The SWT shall have the physical dimensions of 1,60 m to 1,85 m in height, shall weigh
70 kg ± 10 kg and shall wear close-fitting clothing having a recommended emissivity of at
least 80 % between 8 mm and 14 mm wavelength. No metallic objects shall be worn or carried
by the SWT or incorrect microwave reflection will result.
6.1.4.1 Standard walk test target temperature
Temperatures shall be measured at the following five points on the front of the body of the SWT:
1. Head
2. Chest
3. Back of hand
4. Knee
62642-2-4 Ó IEC:2010 – 17 –
5. Feet
Temperatures shall be measured using a non-contact thermometer or equivalent equipment.
The temperature differential at each body point is measured, then weighted and averaged as
detailed in D.1.
There shall be a means of calibration and control of the desired velocity at which the SWT is
required to move.
NOTE The use of a simulator/robot in place of the SWT is permitted, provided that it meets the specification of
the SWT with regard to temperature and microwave reflectivity. It is known as the simulated target. In case of
conflict, a human walk test is the primary reference.
6.1.4.2 Standard walk test target temperature differential
The walk tests shall be performed either with an average temperature differential Dt (as
r
calculated in D.1) of 3,5 °C ± 20 %, or if the temperature differential is larger than 3,5 °C
+ 20 % (4,2 °C), it may be adjusted to achieve an equivalent temperature differential Dte
within this range by one of the means specified in D.2.
If Dt is less than 3,5 °C – 20 % (2,8 °C), no valid test is possible.
r
If Dt is between 2,8 °C and 4,2 °C, no adjustment is required.
r
6.1.5 Testing procedures
The detector shall be mounted at a height of 2,0 m unless otherwise specified by the
manufacturer. The orientation shall be as specified by the manufacturer with unobstructed
view of the walk test to be performed. The detector shall be connected to the nominal supply
voltage, and connected to equipment with a means of monitoring intrusion signals or
messages. The detector shall be allowed to stabilise for 180 s. If multiple sensitivity modes
such as pulse counting are available, any non-compliant modes shall be identified by the
manufacturer. All compliant modes shall be tested.
6.2 Basic detection test
The purpose of the basic detection test is to verify that a detector is still operational after a
test or tests has/have been carried out. The basic detection test verifies only the qualitative
performance of a detector. The basic detection test is performed using the BDT(s).
6.2.1 Basic detection targets (BDT)
The manufacturer shall provide, for testing purposes only, methods for placing either
technology permanently in a state where the other technology may cause an intrusion signal
or message.
The passive infrared BDT consists of a heat source with heat emission equivalent to that of a
human hand, which can be moved across the field of view of the detector. An informative
description is given in Annex E. The temperature of the source shall be between 3,5 °C and
10,0 °C above the background.
The microwave BDT shall be a metal plate having equivalent microwave reflectivity to that of
the human hand, which can be moved across the field of view of the detector.
BDTs may be used separately or together.
A close-in walk test may be carried out as an alternative to using the BDT.

6.2.2 PIR basic detection test
Activate the microwave technology; the unit shall not generate an intrusion signal or message.
A stimulus that is similar to that produced by the SWT is applied to the detector, using the PIR
BDT. Move the PIR BDT perpendicularly across the centre line of the detection field at a
distance of not more than 1 m, and at a height where the manufacturer claims detection will
occur.
–1 –1
Move the PIR BDT a distance of 1 m at a velocity of 0,5 ms to 1,0 ms . The detector shall
produce an intrusion signal or message when exposed to an alarm stimulus both before and
after being subjected to any test that may adversely affect its performance.
