A professionally designed intruder alarm does more than make a noise. It deters intruders, alerts keyholders and the police, and gives you the confidence that your buildings and assets are properly protected — day and night.
Security / Intruder Alarms
Intruder alarm systems are the foundation of security for most commercial premises. Designed and installed correctly, they deter opportunistic break-ins, provide fast notification when an intrusion occurs, and generate the evidence needed for insurance claims and police investigations.
We design and install intruder alarm systems to BS EN 50131 for all types of commercial premises — from simple bell-only systems to multi-zone, monitored systems across complex multi-site estates. Our work meets the standards that most insurers and police forces require.
For clients with multiple sites, we provide consistent design standards and centralised reporting — so you can see the status of your alarm systems across your entire portfolio in one place.
What's Included
Bespoke design based on a survey of your premises — covering detection zones, sensor placement, control equipment and communications.
