What is BS EN 50131-2-8– Shock detectors for intrusion and hold-up systems about?
BS EN 50131 is a European standard on intrusion and hold-up alarm systems. The main objective of the BS EN 51031 series is to establish efficient security and protection systems that minimize the risk and impact of hazardous events.
BS EN 50131-2-8 is one of the parts in the series for shock detectors used as part of intrusion alarm systems 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 includes four security grades and four environmental classes.
BS EN 50131-2-8 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.
BS EN 50131-2-8 does not apply to system interconnections.
Who is BS EN 50131-2-8 - Shock detectors for intrusion and hold-up systems for?
BS EN 50131-2-8 on shock detectors is relevant to:
- Manufacturers of intrusion and hold-up systems
- Manufacturers of intrusion detectors devices
- Manufacturers of shock detectors devices
- Alarm receiving centres (ARC)
- Product designers and engineers
- Installers
- Police
- Insurers
Why should you use BS EN 50131-2-8 - Shock detectors for intrusion and hold-up systems?
The shock detector is intended 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.
BS EN 50131-2-8 is concerned with the requirements and tests for the shock detectors.
BS EN 50131-2-8 provides functional requirements for shock detectors to process various events as per their grade and the generation of indication signals and messages based on these events is covered.
Guidance on detection performance and corresponding tests to verify the same are covered in BS EN 50131-2-8. The test verifies the detection performance for sensitivity and area of coverage. Moreover, requirements for detection performance can help distinguish between environmental shocks and shocks resulting from a physical attack which may be intended to penetrate the structure.
Overall BS EN 50131-2-8 ensures that the shock detectors offer adequate tamper security and immunity to false alarm sources, playing a positive role during an emergency. With efficient detection capabilities, you can thus avoid incidents of failed or delayed intrusion, tamper and fault signals or messages. This can ultimately contribute to the optimal performance of intrusion and hold-up systems.
What’s changed since the last update?
BS EN 50131-2-8:2016 supersedes CLC/TS 50131-2-8:2012, which is withdrawn. The following significant technical changes with respect to CLC/TS 50131-2- 8:2012:
- Changed state from Technical Specification into European Standard
- Clarified wording wherever necessary to avoid misunderstanding and to optimize for reading
- Refined the definition of "shock
- Refined immunity requirements in 4.4.2, 4.4.3, 4.4.4, 4.4.5, and 4.4.6 and their corresponding test subclauses
- Refined the detection of masking requirements in 4.6.5 and the corresponding test sub-clause
