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.

is required to process the output of the sensor, such an event shall be generated alternatively
no generation of a message or signal is required when the condition is detected by the CIE due to system
design

An independent masking signal or message may be provided instead.
b
Alternatively total loss of power supply shall be determined by loss of communication with the detector.
This permits two methods of signalling a masking event: either by the intrusion signal and fault signal, or by a
dedicated output. 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.
When, in Table 1, an event may optionally generate signals or messages, they shall be as shown in this table.

4.2 Operational requirements
4.2.1 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 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
4.2.2 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.
4.2.3 Self tests
4.2.3.1 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.
4.2.3.2 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.
4.3 Detection
4.3.1 Detection performance
4.3.1.1 General
The detector shall generate an intrusion signal or message when a simulated or real glass
breakage according to the corresponding requirements of Table 3 is performed.

4.3.1.2 Verification of detection performance
This test will verify the detection performance for sensitivity and a break through the glass
according to the supported conditions claimed by the manufacturer. It will verify the maximum
covering range (sensitivity performance test) and the break through detection (breakage
performance test), according to Annex A for different glass types and sizes claimed to be
supported (types and dimensions) by the manufacturer. A number of standard glass types and
sizes need to be passed by this test according to the corresponding test section.

– 12 – IEC 62642-2-72:2015 © IEC 2015
4.3.1.3 Performance test for hole drilling with a diamond hole saw
This test will verify the detection performance by drilling a hole using a diamond hole saw on
different glass types and dimensions according to the supported conditions claimed by the
manufacturer and Annex A. It will verify if the detector is able to identify and signal the
change of the integrity of the monitored side of the glass pane.
4.3.1.4 Performance test for glass cutting
This test will verify the detection performance by cutting the glass using a standard glass
cutter on different glass types and dimensions according to the supported conditions claimed
by the manufacturer and Annex A. It will verify if the detector is able to identify and signal the
change of the integrity of the monitored side of the glass pane.
4.3.2 Indication of detection
Powered detectors at grades 3 and 4 that include processing capabilities shall provide an
indicator at the detector to indicate when an intrusion signal or message has been generated.
Self-powered detectors (e.g. detectors which rely on the energy resulting from the glass
breakage) do not require such an indicator.
At grades 3 and 4 this indicator shall be capable of being enabled and disabled remotely at
access level 2.
4.4 Immunity to false alarm sources
4.4.1 General
The detector shall have sufficient immunity to false alarm sources if the following
requirements have been met. No intrusion signal or message shall be generated as a result of
the false alarm sources according to each individual test clause.
The tests for this clause will be performed on the standard immunity test glass pane as
defined in 3.1.7, wherever a glass pane is required.
4.4.2 Immunity to small objects hitting the glass
The detector shall not generate an intrusion signal or message when small objects such as
hail, sand, gravel etc. hit the outside of the monitored glass. The tests are described in 6.7.2.
4.4.3 Immunity to soft objects hitting the glass
The detector shall not generate an intrusion signal or message when soft objects (e.g. a
human fist) hit the outside of the monitored glass. The tests are described in 6.7.3.
4.4.4 Immunity to hard objects hitting the glass
The detector shall not generate an intrusion signal or message when hard objects (e.g.
handlebars of a bicycle) hit the outside of the monitored glass. The tests are described
in 6.7.4.
4.4.5 Immunity to static pressure
The detector shall not generate an intrusion signal or message when permanent pressure
changes applied to the monitored glass. The tests are described in 6.7.5.
4.4.6 Immunity to dynamic pressure
The detector shall not generate an intrusion signal or message when dynamic pressure
changes (due to wind, etc.) applied to the monitored glass. The tests are described in 6.7.6.

4.4.7 Immunity to wide band noise
The detector shall not generate an intrusion signal or message when a wide band of
frequencies at the same time, which are close to the frequency of a glass breakage (e.g.
branches of a tree moving against the window) are applied to the detector. The tests are
described in 6.7.7.
4.5 Tamper security
4.5.1 General
Tamper security requirements for each grade of a detector are shown in Table 4.

a
Not required for wired detectors which are fully potted and where it is not possible to get access to any
adjustments or components.
b
At grade 2 and grade 3 not required if the detector is mounted properly according to the manufacturers
instructions with a two-component / epoxy glue (adhesive and activator), which supports the requested
environmental conditions when mounted and fixed.
c
At grade 2 required for wire free detectors only, if the wire free detectors do not use a two-component /
epoxy glue (adhesive and activator) for fixing.

4.5.2 Resistance to and detection of unauthorised access to the inside of the
detector through covers and existing holes
All components and means of adjustment 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 access without generating a tamper signal or message or
causing visible damage.
4.5.3 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.
4.5.4 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. Alternatively, the detector shall continue to operate
normally.
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

– 14 – IEC 62642-2-72:2015 © IEC 2015
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.
The detection of masking shall operate when the I&HAS is both set and unset.
4.5.5 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 C.
4.6 Electrical requirements
4.6.1 General
These requirements do not apply to detectors having Type C power supplies. For these
detectors refer to IEC 62642-6. For detectors having an external power supply, the
requirements appear in Table 5.
Table 5 – Electrical requirements
Test Grade 1 Grade 2 Grade 3 Grade 4
Detector current consumption Required Required Required Required
Input voltage range Required Required Required Required
Slow input voltage rise Not required Required Required Required
Input voltage ripple Not required Required Required Required
Input voltage step change Not required Required Required Required

4.6.2 Detector current consumption
The detector's quiescent and maximum current consumption shall not exceed the figures
claimed by the manufacturer at the nominal input voltage.
4.6.3 Slow input voltage rise and voltage range limits
The detector shall meet all functional requirements when the input voltage lies between ±25 %
of the nominal value, or between the manufacturers range limits if greater. When the supply
voltage is raised slowly, the detector shall function normally at the specified range limits.
4.6.4 Input voltage ripple
The detector shall meet all functional requirements during the sinusoidal variation of the input
voltage by ±10 % of nominal, at a frequency of 100 Hz.
4.6.5 Input voltage step change
No signals or messages shall be caused by a step in the input voltage between maximum or
minimum and nominal values of the input voltage.

4.7 Environmental classification and conditions
4.7.1 Environmental classification
The environmental classification is described in see IEC 62642-1 and shall be specified by the
manufacturer.
4.7.2 Immunity to environmental conditions
All detectors shall meet the requirements of the relevant environmental class and equipment
class as specified by the manufacturer of the environmental tests described in Table 6 and
Table 7. These tests shall be performed in accordance with IEC 62599-1 and IEC 62599-2.
Impact tests shall not be carried out on delicate detector components such as LEDs or
microphones.
Unless specified otherwise for operational tests, the detector sh
