EN50131

What is EN50131?

The grading of security alarms fitted at UK business premises is outlined in the EN50131 European standards for intruder alarm systems.

This set of guidelines also became known as BS EN50131, after it was adopted by the British Standards Institution. Through their PD6662 scheme, the BSI introduced these European guidelines to boost intruder alarm standards across the UK.

EN50131 was originally adopted back in 2005 but, after various revisions, it remains a crucial reference point for British businesses in 2020 and beyond.
