Introduction
This document is a Technical Specification for shock detectors used as part of intrusion alarm systems
installed in buildings. It includes four security grades and four environmental classes.
The purpose of a shock detector is to detect the shock or series of shocks due to a forcible attack through a
physical barrier (for example doors or windows) and provide the necessary range of signals or messages to
be used by the rest of the intrusion and hold-up alarm system.
The number and scope of these signals or messages will 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 shock detectors.
1 Scope
This Technical Specification is for shock detectors installed in buildings to detect the shock or series of shocks
due to a forcible attack through a physical barrier (for example doors or windows).
It provides for security Grades 1-4 (see EN 50131-1), specific or non specific wired or wire-free detectors and
uses Environmental Classes i-iv (see EN 50130-5).
This Technical Specification does not include requirements for detectors intended to protect for example
vaults and safes from penetration attacks from e.g. drilling, cutting or thermal lance.
This Technical Specification does not include requirements for shock detectors intended for use outdoors.
A detector shall fulfil all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this Technical Specification may be included in
the detector, providing they do not adversely influence the correct operation of the mandatory functions.
This Technical Specification does not apply to system interconnections.

4 Functional requirements
4.1 General
A shock detector consists of a shock sensor and an analyser, which may either be in the same housing, or in
separate housing. Furthermore the analyser can be integrated into another component of the Intruder & Hold
Up alarm system (for example the CIE).
4.2 Event Processing
Shock detectors shall process the events shown in Table 1. Shock detectors shall generate signals or
messages as shown in Table 2.

b
Mandatory for wire-free at all grades. Only required if power is for normal local
operation, e.g. purely switch based solutions do not fall under this requirement; however if
signal processing (except if it is the CIE itself) is required to process the output of the sensor,
such an event shall be generated. No generation of a message or signal is required when
the condition is detected by the CIE due to system design, e.g. bus based systems.
c
Only required if signal processing is used to generate any signal or message, e.g. purely
mechanical based solutions do not fall under this requirement. No generation of a message
or signal is required when the condition is detected by the CIE due to system design, e.g. bus
based systems.

* An independent 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 shock detector. If multiple events overlap there will be some signal combinations
that may be ambiguous. To overcome this ambiguity it is suggested that shock detectors
should not signal ‘intrusion‘ and ‘fault‘ at the same time except to indicate masking. This
implies that the shock detector should prioritise signals, e.g. 1 Intrusion, 2 Fault, 3 Masking.
** Alternatively Total loss of Power Supply shall be determined by loss of communication with the
shock detector.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages,
they shall be as shown in this table.
NOTE 3 It is accepted that a bus system may send out dedicated signals or
messages and does not necessarily have to follow the mapping of Table 2, provided that all
of the required events are signalled.
4.3 Detection
4.3.1 Detection performance
4.3.1.1 Generalities
The shock detector shall be designed to distinguish between environmental shocks and shocks resulting from
a physical attack which may be intended to penetrate the structure. The means for achieving this may be
adjustable to suit varying circumstances.
The operating parameters of the shock detector shall be verified as specified by the manufacturer.
The manufacturer shall clearly state in the product documentation, any special limitation concerning
installation e.g. area of coverage etc.
The shock detector shall generate an intrusion signal or message when a simulated structure penetration is
performed at all grades.
4.3.1.2 Verification of gross attack detection performance
This test will verify the detection performance for sensitivity and area of coverage, according to the supported
conditions claimed by the manufacturer for a gross attack.
There are minimum performance requirements for gross attack detection which need to be fulfilled by the
shock detector according to Table G.1.
Furthermore, the manufacturer can specify other performance requirements, which need to be verified by
testing against the performance specifications provided by the manufacturer.
The manufacturer shall specify the lowest and the highest detection level of the supported area of coverage
on a specified material for an impact defined at a certain energy level according to Table G.1. Each of the
specified lowest and highest detection levels will be tested.
4.3.1.3 Verification of low shock integration attack detection performance
This test will verify the detection performance for sensitivity and area of coverage according to the supported
conditions claimed by the manufacturer for a low shock integration attack.
This test only applies, if the manufacturer claims his product supports this feature
There are minimum performance requirements for low shock integration attack detection which need to be
fulfilled by the shock detector according to Table G.1.
Furthermore, the manufacturer can specify other performance requirements, which will be verified by testing
against the performance specifications provided by the manufacturer.
The manufacturer shall specify the lowest and the highest detection level of the supported area of coverage
on a specified material for an impact defined at a certain energy level as specified in Table G.1. Each of the
specified lowest and highest detection levels will be tested.
4.3.2 Indication of detection
Powered shock 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 shock
detectors (e.g. detectors which rely on the energy resulting from the impact or a series of impacts) do not
require such an indicator.
- 11 - CLC/TS 50131-2-8:2012
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.
If not defined in the individual test section differently, for this clause the tests will be performed on the
standard immunity test window as defined in 3.1.10, wherever a monitored object is required.
4.4.2 Immunity to Small objects hitting a framed window
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 surface, when set to the chosen sensitivity level required to pass the
gross attack detection performance test. The tests are described in 6.7.2.
4.4.3 Immunity to Hard objects hitting a framed window
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 surface, when set to the chosen sensitivity level required to pass the
gross attack detection performance test. The tests are described in 6.7.3.
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 surface, when set to the chosen sensitivity level required to pass the gross attack detection
performance test. The tests are described in 6.7.4.
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 surface, when set to the chosen sensitivity level required to pass the gross
attack detection performance test. The tests are described in 6.7.5.
4.4.6 Standard Immunity Test
The detector shall not generate an intrusion signal or message when for each standard installation material
(glass plate, wooden plate & concrete plate as defined in Annex A), a minimum force will be issued at a given
distance from the detector, when set to the chosen sensitivity level required to pass the gross attack detection
performance test. The tests are described in 6.7.6.
4.5 Operational requirements
4.5.1 Time interval between intrusion signals or messages
Shock detectors using wired interconnections 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.
Shock detectors using wire free interconnections 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
4.5.2 Switch on delay
The shock detector shall meet all functional requirements within 180 s of the power supply reaching its
nominal voltage as specified by the manufacturer.
4.5.3 Self tests
4.5.3.1 Local Self Test
The shock 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 shock detector is inhibited during a local self-test, the shock
detector inhibition time shall be limited to a maximum of 30 s in any period of 2 h.
4.5.3.2 Remote Self Test
A shock 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
4.6 Tamper security

4.6.2 Resistance to and detection of unauthorised access to components and means of adjustment
All components, means of adjustment and access to mounting screws, which, when interfered with, could
adversely affect the operation of the shock detector, shall be located within the shock detector or each
individual component the shock detector consists of. Such access shall require the use of an appropriate tool
and depending on the grade as specified in Table 3, shall generate a tamper signal or message before access
can be gained.
It shall not be possible to gain such access without generating a tamper signal or message or causing visible
damage. Sealed detectors do not require the means to detect access to the inside of the detector, as long as
access to any adjustments is not possible or generates a tamper signal or message before access can be
gained.
4.6.3 Detection of removal from the mounting surface
A tamper signal or message shall be generated if the shock sensor is removed from its mounting surface, in
accordance with Table 3.
4.6.4 Resistance to magnetic field interference
It shall not be possible to inhibit any signals or messages with a magnet of grade dependence according to
Table 3.
4.6.5 Detection of masking
Means shall be provided to detect inhibition of the operation of the shock sensor by masking according to the
requirements of Table 3. For grade 3 products it is allowed that the detector is immune to a masking condition
and operates within the normal boundaries as specified by the manufacturer.
There are different potential ways of masking a shock sensor. Therefore two different tests will be performed
dependent on grade.
The first masking test will be to immobilise the active sensor component of a shock sensor with a magnetic
field in a position, where it is no longer able to detect gross attacks and/or low shock integration attacks.
The second masking test will verify the ability of the shock sensor housing to detect the unauthorized access
to prevent the fixing of the active sensor component of a shock sensor e.g. via a screw or superglue.
NOTE 1 In an I&HAS, any masked shock sensor should prevent setting of the system, as long as it is not immune to the
masking condition.
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 shock sensors and/or detectors to
automatically reset after the masking condition is removed.
For shock 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.
4.7 Electrical requirements
4.7.1 General
The grade dependencies appear in Table 4. These requirements do not apply to shock detectors having Type
C power supplies. For these shock detectors refer to EN 50131-6.

4.7.2 Shock detectors current consumption
The shock detectors or its individual components (sensor and/or analyser), when applicable, quiescent and
maximum current consumption shall not exceed the figures claimed by the manufacturer at the nominal input
voltage.
4.7.3 Slow input voltage change and voltage range limits
The shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet all
functional requirements when the input voltage lies between ± 25 % of the nominal value, or between the
manufacturer’s stated values if greater. When the supply voltage is raised slowly, the shock detectors or its
individual components (sensor and/or analyser), when applicable, shall function normally at the specified
range limits.
4.7.4 Input voltage ripple
The shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet all
functional requirements during the sinusoidal variation of the input voltage by ± 10 % of nominal, at a
frequency of 100 Hz.
4.7.5 Input voltage step change
No signals or messages shall be caused by a step in the input voltage between nominal and maximum and
between nominal and minimum.
4.8 Environmental classification and conditions
4.8.1 Environmental classification
The environmental classification is described in EN 50131-1 and shall be specified by the manufacturer.
- 15 - CLC/TS 50131-2-8:2012
4.8.2 Immunity to environmental conditions
Shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet the
requirements of the environmental tests described in Tables 5 and 6. These tests shall be performed in
accordance with EN 50130-5 and EN 50130-4.
Unless specified otherwise for operational tests, the shock detectors or its individual components (sensor
and/or analyser), when applicable, shall not generate unintentional intrusion, tamper, fault or other signals or
messages when subjected to the specified range of environmental conditions.
Impact tests shall not be carried out on delicate shock detector components such as LEDs, optical windows or
lenses.

6 Testing
6.1 General
The tests are intended to be primarily concerned with verifying the correct operation of the shock 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 C.
6.2 General test conditions
6.2.1 Standard conditions for testing
The general atmospheric conditions in the measurement and tests laboratory shall be those specified in
EN 60068-1:1994, subclause 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
6.2.2 General detection testing environment and procedures
6.2.2.1 General
Manufacturer’s documented instructions regarding mounting and operation shall be read and applied to all
tests.
6.2.2.2 Testing environment
The detectors sensor elements will be mounted according to the manufacturer’s description on the monitored
object (e.g. glass window, concrete wall or door).
6.2.2.3 Test procedures
The tests will be performed with the types of materials claimed to be supported by the manufacturer, but at
least with the materials defined in Annex A to perform the minimum detection performance tests.
The detector or its individual components (sensor and/or analyser), when applicable, shall be connected to the
nominal supply voltage and connected to the monitoring system that is appropriate to the test. It 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. The detector shall be mounted according to the installation instructions, any cover(s) shall be
mounted properly before any test takes place.
6.3 Basic Detection Test
6.3.1 General
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.
6.3.2 Basic Detection Test Method
The detector shall generate an intrusion signal or message when the detector or its individual components
(sensor/s), when applicable, are mounted according to the manufacturer instructions, set to maximum
sensitivity level and tests are carried out according to 6.4.2.2.
The test will be performed according to the manufacturer’s instructions after the first installation, the settings
and results will be noted to verify that all detectors or its individual components (sensor/s), when applicable,
are installed correctly, it will be called the initial test. It will be performed again, after and/or during the
environmental tests under the same
