Which Alarm Grade Do You Need?
Under BS EN 50131, intruder alarm systems are graded from 1 (basic domestic) to 4 (maximum security). The right grade depends on your risk profile, assets and insurer requirements.
Alarm grade requirements are determined by your insurer, a site risk assessment, police guidelines and BS EN 50131 / PD 6662:2017. The result above is a guide based on the most common indicators. Always confirm the required grade with your insurer and a certificated engineer before installation. All Prism installations include a formal grade assessment as part of the free site survey.
