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.

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
This International Standard deals with passive infrared 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 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.

An independent signal or message may be provided instead.
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.
b
Alternatively total loss of power supply shall be determined by loss of communication
with the detector.
When, in Table 1, an event may optionally generate signals or messages, they shall be as
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 (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 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.
62642-2-2 © IEC:2010 – 13 –
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 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 a car headlamp is swept across
the front window or lens through two panes of glass.
4.5 Tamper security
Tamper security requirements for each grade of detector are shown in Table 4.
– 14 – 62642-2-2 © IEC:2010
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.
NOTE 1 In an I&HAS, any masked detectors should prevent setting of the system.
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 2 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.

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 (RH) 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 walls and floor shall have a recommended emissivity of at least 80 % between
8 μm and 14 μm 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.
The default mounting height shall be 2,0 m unless otherwise specified by the manufacturer.
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
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 μm and 14 μm wavelength.
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,
– 18 – 62642-2-2 © IEC:2010
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. It is known as the simulated target. In case of conflict, a human walk test is
the primary reference.
6.1.4.1 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.
is less than 3,5 °C – 20 % (2,8 °C), no valid test is possible.
If Dt
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 basic detection
target (BDT).
6.2.1 Basic detection target (BDT)
The BDT consists of a heat source equivalent to the human hand that 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.
A close-in walk test may be carried out as an alternative to using the BDT.
6.2.2 Basic test of detection capability
A stimulus that is similar to that produced by the SWT is applied to the detector, using the
BDT. Move the 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 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.
62642-2-2 © IEC:2010 – 19 –
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 bet

INTRODUCTION
This part 2-2 of the IEC 62642 series of standards gives requirements for passive infrared
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 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
This International Standard deals with passive infrared 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 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.

1 Scope
This part of the IEC 62642 is for passive infrared detectors installed in buildings and provides
for security grades 1 to 4 (see IEC 62642-1), specific or non-specific wired or wire-free
detectors, and uses environmental classes I to IV (see IEC 62599-1). This International
Standard does not include requirements for passive infrared 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.
This International Standard does not apply to system interconnections.

An independent signal or message may be provided instead.
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.
b
Alternatively total loss of power supply shall be determined by loss of communication
with the detector.
When, in Table 1, an event may optionally generate signals or messages, they shall be as
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.

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 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.

4.5.1 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.

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.
NOTE 1 In an I&HAS, any masked detectors should prevent setting of the system.
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 2 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.
