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.
