Foreword
This document (EN 50131-2-7-1:2012) has been prepared by CLC/TC 79 "Alarm systems".
The following dates are fixed:
• latest date by which this document has to be
(dop) 2013-08-13
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards
(dow) 2015-08-13
conflicting with this document have to
be withdrawn
This document supersedes CLC/TS 50131-2-7-1:2009.
This European standard provides for security Grades 1 to 4 (see EN 50131-1) passive acoustic glass
break detectors installed in buildings, and uses environmental classes I to IV (see EN 50130-5).
The purpose of a detector is to detect the acoustic energy exclusively emitted by the physical
destruction of a glass pane, which allows intrusion to the monitored area for example in doors,
windows or enclosures 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 standard is only concerned with the requirements and tests for the detector. Other types of
detectors are covered by other documents identified as TS / EN 50131-2-x.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.

An independent masking signal or message may be provided instead.

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 Table 2.
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 of a glass breakage according to the supported
conditions claimed by the manufacturer. It will verify the covering range including the maximum and
minimum range as well as the performance of randomly chosen mounting locations of the detector,
according to Annex B 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.
4.3.1.3 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 B. 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 B. 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.
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
section 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 single frequency sound sources
The detector shall not generate an intrusion signal or message when various frequencies and levels of
noise (like brakes of a lorry, etc.) are applied to the detector. The tests are described in 6.7.5.
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 6.7.6 and 6.7.7.
4.5 Tamper security

Tamper security requirements for each Grade of a detector are shown in Table 4.
