Bibliography 42Fo reword
This document (CLC/TS 50131-2-8:2012) has been prepared by CLC/TC 79 "Alarm systems".
This document was circulated for voting in accordance with the Internal Regulations, Part 2, Subclause 11.3.3.3.
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. 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.

3 Terms, definitions and abbreviations
For the purposes of this document, the terms, definitions and abbreviations given in EN 50131-1 and the following apply.
3.1 Terms and definitions
3.1.1
shock
sudden transient acceleration or deceleration e.g. caused by a mechanical impact as a result of a forcible attack through a physical barrier
3.1.2
incorrect operation
physical condition that causes an inappropriate signal or message from a shock detector
3.1.3
masking
interference with the shock detector input capability, which prohibits the triggering of the shock detector (e.g. disabling the detector with an external magnet)
3.1.4
shock test
operational test, during which a shock detector is activated by using the standard triggering method in a controlled environment
3.1.5
shock detector
combination of one or more shock sensor(s) and an analyser, which provides signalling or messaging to the Intruder & Hold Up alarm system
3.1.6
shock sensor
element which detects the mechanical shock energy and produces a signal for further analysing
3.1.7
analyser
physical unit or processing capabilities used to process the signal(s) produced by one or more shock sensor(s) and provides a signal or message to the intruder & Hold Up alarm system
3.1.8
mass inertia
physical underlying principle which will be used for sensing a shock e.g. a weighted or piezo transducer sensor
3.1.9
gross attack
large single shock due to a impact on the super
