Introduction
This document is a European Standard 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).
The shock detector has to 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 European Standard is only concerned with the requirements and tests for the shock detectors. Other
types of detectors are covered by other documents identified as in the EN 50131-2 series.
1 Scope
This European Standard 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 specifies four security Grades 1-4 (in accordance with EN 50131-1), specific or non-specific wired or wire-
free detectors and uses environmental Classes I-IV (in accordance with EN 50130-5).
This European Standard does not include requirements for detectors intended to detect penetration attacks on
safes and vaults for example by drilling, cutting or thermal lance.
This European Standard does not include requirements for shock detectors intended for use outdoors.
A detector needs to fulfil all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this European Standard may be included in the
detector, providing they do not adversely influence the correct operation of the mandatory functions.
This European Standard does not deal with requirements for compliance with regulatory directives, such as
EMC-directive, low-voltage directive, etc., except that it specifies the equipment operating conditions for EMC-
susceptibility testing as required by EN 50130-4.
This European Standard does not apply to system interconnections.

4 Functional requirements
4.1 General
A shock detector consists of one or more shock sensor and an analyser, which may either be in the same
housing, or in separate housings. 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 in accordance with Table 1.

for wired, sealed / potted and flush mounted types grade 3.
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.
Shock detectors shall generate signals or messages in accordance with Table 2.

* 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 General
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 verifies the detection performance for sensitivity and area of coverage, according to the claims made
by the manufacturer for detection of a gross attack.
The shock detector shall meet the minimum performance requirements for gross attack detection according to
Table F.1.
The manufacturer may specify other performance requirements, which shall 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 coverage area on a specified
material for an impact defined at a certain energy level according to Table F.1. Each of the specified lowest
and highest detection levels shall be tested.
4.3.1.3 Verification of low shock integration attack detection performance
This test verifies the detection performance for sensitivity and area of coverage according to the claims made
by the manufacturer for detection of a low shock integration attack.
This test only applies, if the manufacturer claims the product supports this feature
The shock detector shall meet the minimum performance requirements for low shock integration attack
detection according to Table F.1.
The manufacturer may specify other performance requirements, which shall be verified by testing against the
performance specifications provided by the manufacturer.
The manufacturer shall specify the lowest and the highest detection level for the coverage area on a specified
material for an impact defined at the energy level as specified in Table F.1. Each of the specified lowest and
highest detection levels shall 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.
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.
Unless stated otherwise in the individual test section, the tests shall be performed on the standard immunity
test window as defined in 3.1.11, wherever a monitored object is required.
4.4.2 Immunity to Small objects hitting a framed window
The detector, when set to the chosen sensitivity level required to pass the gross attack detection performance
test, shall not generate an intrusion signal or message when small objects such as hail, sand, gravel etc. hit
the outside of the monitored surface.
The test is described in 6.7.2.
4.4.3 Immunity to Hard objects hitting a framed window
The detector, when set to the chosen sensitivity level required to pass the gross attack detection performance
test, shall not generate an intrusion signal or message when hard objects (e.g. handlebars of a bicycle) hit the
outside of the monitored surface.
The test is described in 6.7.3.
4.4.4 Immunity to Static pressure
The detector, when set to the chosen sensitivity level required to pass the gross attack detection performance
test, shall not generate an intrusion signal or message when static pressure changes are applied to the
monitored surface.
The test is described in 6.7.4.
4.4.5 Immunity to Dynamic pressure
The detector, when set to the chosen sensitivity level required to pass the gross attack detection performance
test, shall not generate an intrusion signal or message when dynamic pressure changes (due to wind, etc.)
are applied to the monitored surface.
The test is described in 6.7.5.
4.4.6 Standard Immunity Test
The detector shall not generate an intrusion signal or message when an impact of minimum energy level is
applied at a given distance from the detector, when the detector is set to the chosen sensitivity level required
to pass the gross attack detection performance test. The test is performed on each of the standard installation
materials (i.e. glass plate, wooden plate & concrete plate) as defined in Annex A.
The test is 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 time for which
the detector is inhibited 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. The detector shall return to normal operation
within 30 s of the remote test signal being received
4.6 Tamper security
4.6.1 General
The tamper security requirements for each grade of shock detector are shown in Table 3. The requirements
apply to the shock detector and its individual components (e.g. multiple sensors).

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 housing. 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 an attempt 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
Subject to grade in accordance with Table 3, it shall not be possible to inhibit any signals or messages using a
magnet
4.6.5 Detection of masking
In accordance with Table 3 means shall be provided to detect if the operation of the shock sensor is inhibited
due to masking.
For Grade 3 products, if a detector continues to operate within its normal boundaries after the application of a
masking condition, then it need not issue a masking signal or message.
There are different ways of masking a shock sensor. Therefore two different tests shall be performed
dependent on grade.
The first masking test shall attempt to immobilise the active sensor component of a shock sensor with a
magnetic field in a position, such that it is no longer able to detect gross attacks and/or low shock integration
attacks.
The second masking test shall verify the ability of the shock detector to detect an attempt to gain unauthorized
access by drilling though the active sensor component housing with the aim of trying to prevent the proper
operation of the active sensor component
In an I&HAS, any masked shock sensor should prevent setting of the system, as long as it is affected by 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 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.

4.7.4 Input voltage ripple
The shock detector shall meet all functional requirements during the modulation of the input voltage by a peak
to peak voltage of 10 % of the nominal values, at a frequency of 100 Hz.
