BS EN 50131-2-8:2025

This document 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 shock detectors and uses environmental Classes I-IV (in accordance with EN 50130-5). This document does not include requirements for detectors intended to detect penetration attacks on safes and vaults for example by drilling, cutting or thermal lance. This document does not include requirements for shock detectors intended for use outdoors. A shock detector needs to fulfil all the requirements of the specified grade. Functions additional to the mandatory functions specified in this document can be included in the shock detector, providing they do not adversely influence the correct operation of the mandatory functions. This document 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 document does not apply to system interconnections.
