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.

M = Mandatory, Op = Optional

Mandatory for wire-free at grades 2, 3 and 4; mandatory for all surface mounted grade 3

and 4 types, optional for wired surface mounted grades 1 and 2. Not required for wired,

concealed flush mounted types grade 3.

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.

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.
---------------------- Page: 12 ----------------------
SIST-TS CLC/TS 50131-2-8:2012
- 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.
