Foreword
This Technical Specification was prepared by the Technical Committee CENELEC TC 79, Alarm systems.
The text of the draft was circulated for voting in accordance with the CEN/CENELEC Internal Regulations,
Part 2, Subclause 11.3.3.3 and was approved by CENELEC as CLC/TS 50131-2-7-1 on 2009-03-06.
The following date was fixed:
– latest date by which the existence of the CLC/TS
has to be announced at national level (doa) 2009-09-06
EN 50131 will consist of the following parts, under the general title “Alarm systems – Intrusion and hold-up
systems”:
Part 1 System requirements
Part 2-2 Intrusion detectors - Passive infrared detectors
Part 2-3 Requirements for microwave detectors
Part 2-4 Requirements for combined passive infrared and microwave detectors
Part 2-5 Requirements for combined passive infrared and ultrasonic detectors
Part 2-6 Opening contacts (magnetic)
Part 2-7-1 Intrusion detectors - Glass break detectors (acoustic)
Part 2-7-2 Intrusion detectors - Glass break detectors (passive)
Part 2-7-3 Intrusion detectors - Glass break detectors (active)
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 device/system
This Technical Specification 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 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 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.

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

4.3.1.1 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.
4.3.1.2 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 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.
4.3.1.3 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 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. 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.
4.4.2 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 6.6.2.
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 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 6.6.4.
4.4.5 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 6.6.5 and 6.6.6.
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 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 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.
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.
