Foreword

This document (EN 50131-2-7-2:2012) 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be withdrawn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 50131-2-7-2:2009.

This European Standard provides for security Grades 1 to 4 (see EN 50131-1) glass break (passive)

detectors installed in buildings, and uses environmental classes I to IV (see EN 50130-5).

The purpose of a detector is to detect the 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.

4.1 Event Processing

Detectors shall process the events shown in Table 1. Detectors shall generate signals or messages as

shown in Table 2.

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 this table.

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

---------------------- Page: 11 ----------------------
SIST EN 50131-2-7-2:2012
EN 50131-2-7-2:2012 - 10 -

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
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.
