BS EN 50131-2-7-2:2012+A2:2016

What is BS EN 50131-2-7-2 – Passive surface-mounted glass break detectors 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 50131-2-7-2 is one of the parts in the multi-series for passive surface-mounted glass break detectors installed in buildings and provides for security Grades 1 to 4 specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV.  

Functions additional to the mandatory functions specified in this standard may be included in the detector, providing they do not adversely influence the correct operation of the mandatory functions. 

BS EN 50131-2-7-2 does not include requirements for passive surface mounted glass break detectors intended for use outdoors.  

BS EN 50131-2-7-2 does not apply to system interconnections.  

Who is BS EN 50131-2-7-2 - Passive surface-mounted glass break detectors for? 

BS EN 50131-2-7-2 on glass break detectors is relevant to: 

• Manufacturers of intrusion and hold-up systems 
• Manufacturers of intrusion detectors devices 
• Manufacturers of glass break detectors devices 
• Alarm receiving centres (ARC) 
• Product designers and engineers 
• Installers 
• Police 
• Insurers 

Why should you use BS EN 50131-2-7-2 - Passive surface-mounted glass break detectors? 

A passive surface mounted glass break detector is the detector that is mounted on a glass pane, which detects the energy emitted by a glass breakage of the pane the detector is mounted on. 

BS EN 50131-2-7-2 provides functional requirements for detectors to process various events as per their grade and the generation of indication signals and messages based on these events is covered. The signals or messages are of three types: intrusion, tamper and fault. 

Guidance on detection performance and corresponding tests to verify the same are covered in BS EN 50131-2-7-2. This test can verify the maximum covering range (sensitivity performance test) and the break through detection (breakage performance test), for different glass types and sizes. 

Overall BS EN 50131-2-7-2 ensures that the glass break 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.
