This Technical Specification provides for security grades 1 to 4 (see EN 50131-1) glass break detectors
(active) installed in buildings and uses environmental classes I to IV (see EN 50130-5).
The purpose of a detector is to detect changes to the integrity of a glass barrier (for example in doors,
windows or enclosures) that the transmitting and receiving unit(s) are directly mounted on, which allows
intrusion to the monitored area and to provide the necessary range of signals or messages to be used by the
rest of the intruder alarm system.
Functions additional to the mandatory functions specified in this standard may be included in the detector,
providing they do not adversely influence the correct operation of the mandatory functions.
The number and scope of these signals or messages may be more comprehensive for systems that are
specified at the higher grades.
This Technical Specification is only concerned with the requirements and tests for the detector. Other types
of detectors are covered by other documents identified as EN 50131-2-X / CLC/TS 50131-2-X.

a
An independent masking signal or message may be provided instead.
NOTE 1 This permits two methods of signalling a masking event: either by the intrusion
signal and fault signal or by a dedicated masking 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.
NOTE 2 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 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.

4.3.1.1 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.
4.3.1.2 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.
4.3.1.3 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
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.
4.4.1 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 6.6.1.

outside of the monitored glass. The tests are described in 6.6.2.
4.4.3 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 6.6.3.
4.4.4 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 6.6.4.
4.4.5 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 6.6.5.
4.4.6 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 6.6.6 and 6.6.7.
4.5 Tamper security
Tamper security requirements for each grade of a detector are shown in Table 4.

4.5.1 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.
4.5.2 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 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.
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.
The detection of masking shall operate when the I&HAS is both set and unset.
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 C.
4.6 Electrical requirements
These requirements do not apply to detectors having type C power supplies. For these detectors refer to

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 I.
6.1 General test conditions
6.1.1 Standard laboratory conditions for testing
The general atmospheric conditions in the measurement and tests laboratory shall be those specified in
EN 60068-1:1994, 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.
6.1.2.1 Testing environment
The detectors or sensor elements will be mounted according to the manufacturer’s description on the
monitored object (glass window or door glass pane). Some tests will be performed on the monitored object,
others will be performed on panes (unframed window), where the detectors are mounted directly on.
6.1.2.2 Test procedures
The tests will be performed with the types of glass claimed by the manufacturer. These tests will be
performed with the sizes and thicknesses of glass as specified in Annex A.
Additionally, tests will be performed with the maximum size claimed by the manufacturer if this is greater
than the maximum size specified in Annex A.
Additional test will be performed with the thinnest glass claimed by the manufacturer, if this is thinner than
the minimum thickness specified in Annex A.
The detector shall be connected to the nominal supply voltage and connected to the monitoring system that
is appropriate to the test. The detector shall be allowed to stabilise for 180 s. The intrusion signal or message
output shall be monitored. If multiple sensitivity modes 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 the detector.
The basic detection test is performed using the BTS.
6.2.1 Basic test source
For functional verification there shall be a device available which will simulate a glass breakage or
destruction, without breaking the glass (BTS), alternatively a pane of standard sized glass (see Annex A) can
be broken to verify the detection. The Basic Test Source (BTS) which is specified by the manufacturer
simulates the breaking of a standard glass window by the low energy attack test.
This device should be a test device, which is specified for testing through simulation of a glass break from or
recommended by the manufacturer.
This device should simulate a glass breakage or destruction, by pressing the device onto the monitored
glass and simulating a sound, frequency or condition, which needs to be detected.
6.2.2 Basic detection test method
The detector shall generate an intrusion signal or message when a test device (BTS) is used to simulate a
glass breakage. The test will be performed according to the manufacturer’s instructions after the first
installation, to verify, that all detectors are installed properly. It will be performed again, after or/and during
the environmental tests under the same conditions the tests had been performed the first time, to verify that
the detectors will still function the way, the manufacturer claims to support (e.g. detection range) and to
compare this results with the results of the initial test.
If the test is not compatible with the detector, use the manufacturer’s information to generate the correct
algorithm.
The detector(s) 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.
6.3 Performance tests
The general test conditions of 6.1.2 shall apply to all tests in this series.
Detection performance shall be tested against the manufacturer’s documented claims. Any variable controls
shall be set to the values recommended by the manufacturer to achieve the claimed performance.
The detectors shall be assessed in the specified test environment.
– 15 – CLC/TS 50131-2-7-3:2009
6.3.1 Verification of detection performance
All performance tests are based on physical destruction characteristics (e.g. the sound of breakage) of the
size, thickness and types of glass claimed to be supported by the manufacturer including the standard glass
types listed in Annex A, if claimed to be supported by the manufacturer.
6.3.1.1 Sensitivity performance test
The test will be performed for each glass type claimed to be supported by the manufacturer. Each glass
pane will be positioned on support pieces, to ensure that the glass break signal can reach the detectors
undampened.
Three sender and receiver pairs (or combined sensor elements) shall be mounted according to the
manufacturer’s installation instructions on the monitored glass (if a simultaneous installation is not supported,
the test shall be performed for each detector separately), at the maximum distance of the planned glass
breakage claimed to be supported by the manufacturer. The maximum distance claimed to be supported, will
determine the size of the glass pane. This actually means that one combined sensor element will be
mounted at the maximum distance and the rest of the combined sensor elements will be mounted parallel to
this combined sensor element along the far edge of the glass according to Annex K, within the range claimed
to be supported.
In case the sensor element consists out of a sender and receiver pair, they shall be installed according to the
manufacturer’s instruction and the maximum distance will be measured from the receiver element. In case
more than one detector element can be tested at the same time, the other two receivers shall be mounted
adjacent to the first receiver element along the far edge to the glass according to Annex K.
To verify the sensitivity, the edge of the glass will be broken with a pair of pliers at the far distance end
relative to the position of one receiver or combined sensor element, given that the other 2 receiver or
combined sensor elements are still in the claimed to be supported area. The pliers shall be placed in a way,
that they will hold 100 mm² – 150 mm² of the glass, when the breakage is performed. The output of the
detectors will be monitored for detection of the glass breakage. This will be performed 3 times for each glass
type; it is allowed to repeat the test on the same pane, if the pane will support it.
Pass/Fail criteria: 8 out of 9 attempts shall be detected for each glass type.
6.3.1.2 Breakage performance test
These tests shall use the physical destruction characteristics (e.g. the sound of breakage), thickness and
types of glass claimed to be supported by the manufacturer including the standard glass types listed in
Annex A, if claimed to be supported by the manufacturer:
For each glass type claimed to be supported by the manufacturer, 2 panes with nominal thickness of
Annex A and standard size of Annex A will be tested by dropping a steel ball according to the test set up of
Annex J. 8 samples shall be used to measure the detection performance (if a simultaneous installation is not
supported, the test shall be performed for each detector separately and may require one pane per detector).
Pass/Fail criteria: At least 7 out of 8 attempts shall be detected for each glass type.
The detectors shall be mounted at different positions according to the installation instructions of the
manufacturer.
6.3.2 Hole drilling with a diamond hole saw
This test will be performed according to the grading listed in Table 3.
The drilling of a hole using a diamond hole saw will be performed. It will be verified, if the detector is able to
identify and signal the change of the integrity of the monitored side of the glass pane. Three detectors will be
mounted according to the installation instructions of the manufacturer (if a simultaneous installation is
supported, otherwise the test must be repeated three times one by one). A diamond hole saw with a
diameter of 20 mm (± 1 mm) will be used to drill a hole into the glass pane opposite to the monitored side.
This will be performed once in the most distant position to the detector or its sensors and four times on
randomly chosen positions within the coverage range claimed to be supported by the manufacturer.
Pass/Fail criteria: The test is passed successfully, if the detector(s) has indicated the change of the integrity
of the glass pane for the most distant position and detected at least three out of the four attempts on the
randomly chosen positions. In case the change of integrity for the most distant position was not indicated, it
is allowed to carry out three more tests in the most distant position, whereas all of them need to be indicated
by the detector.
A change of integrity of a glass pane can be either a successful hole drilling or a destruction of the glass,
complete or in parts, which allows access to the side where the detector or the sensor(s) are mounted.
These tests need to be repeated for each glass type with the maximum size and minimum thickness claimed
to be supported by the manufacturer.
6.3.3 Glass cutting
This test will be performed according to the grading listed in Table 3.
Three detectors or sensor elements will be mounted according to the manufacturer’s installation instructions
(if a simultaneous installation is supported, otherwise the test must be repeated three times one by one).
A standard glass cutter will be used to cut a piece of glass on the opposite side where the detector or its
sensor element is mounted and the cut piece will be carefully broken. This will be performed once in the
most distance position to the detector or its sensors and four times on randomly chosen positions. At one
location there will be a circle created, with a diameter of 100 mm ± 10 mm and carefully removed out of the
glass pane.
Pass/Fail criteria: The test is passed successfully, if the detector(s) has indicated the change of the integrity
of the glass pane for the most distant position and detected at least three out of the four attempts on the
randomly chosen positions. In case the change of integrity for the most distant position was not indicated, it
is allowed to carry out three more tests in the most distant position, whereas all of them need to be indicated
by the detector.
A change of integrity of a glass pane can be either a successful glass cutting or a destruction of the glass,
complete or in parts, which allows access to the side where the detector or the sensor(s) are mounted.
All of the tests need to be repeated for each
