If your alarm goes off, will anyone come?
Most homeowners assume that someone’s watching their monitored alarm and that the police will respond, but this isn’t always the case.
Here's what DOES happen:
1. Your monitored alarm will connect to an Alarm Receiving Centre (ARC). This is a 24/7 staffed facility, watching for signals from your system.
2. What happens next depends on whether your system has a police URN (Unique Reference Number).
✅ If it does have a URN, the ARC can call your local police force directly, treating your alert as a verified, priority incident. This means an average 8-minute response.
❌ If it doesn’t have a URN, the ARC can only call 999, like any other member of the public. This means no guaranteed response time, and worryingly, officers may not be dispatched at all.
This means that although two “monitored” alarms may look similar, they could perform completely differently in an emergency because of who fitted them. 😱
Want to know how to get a URN? Simple - your system must meet the required standard AND your installer must be NSI or SSAIB-accredited, just like Absolute Fire & Security.
