5-Star Intruder Alarm Monitoring Company
Intruder Alarm Monitoring
A bells-only alarm relies on someone nearby caring enough to call. At 3am on an industrial estate, nobody does. Britannia’s intruder alarm monitoring service sends every activation to a 24-hour alarm receiving centre, where trained operators verify it and get the right people moving.
Monitored alarms that get a response
Monitoring matters most to the people called when the alarm goes off: keyholders, site managers and estates teams.
- Verified before anyone’s called. Alarm signals are confirmed remotely, and linked CCTV can show operators what triggered the alarm.
- The right people contacted. Nominated keyholders, or emergency services where the alarm meets the required criteria.
- Fewer false alarms. Routine servicing helps prevent false alarms and technical issues. Alarms should be serviced at least once a year.
- Insurance benefits. A monitoring service can help with insurance premiums.
- One provider. Britannia installs, maintains and monitors intruder alarms, and can survey and take over the maintenance and monitoring of an existing system.
Police response rules for monitored alarms
Monitoring alone doesn’t guarantee police attendance. In England, Wales and Northern Ireland, the NPCC Security Systems Policy (2026) only gives police response to a system that is:
- installed, maintained and monitored by a company certified by a UKAS-accredited body (in practice NSI or SSAIB) and on the force’s compliant list
- designed to PD 6662:2017, with BS 8243 alarm confirmation
- monitored by an alarm receiving centre certified to BS EN 50518 (or the older BS 5979)
- registered with a URN, with at least two keyholders able to attend within 20 minutes
Response is Level 1 (immediate, not guaranteed) or Level 3 (withdrawn, keyholders only). Two false alarms in a rolling 12 months brings a warning letter; a third moves you to Level 3. To restore it, an unconfirmed system needs upgrading to BS 8243 confirmation, and a confirmed one needs the cause fixed and 90 days clear. If reinstatement hasn’t started within six months, the URN is deleted.
Systems without a URN get no police call from the monitoring centre: someone at the scene must report a crime in progress on 101 or 999. Police Scotland applies its own rules. And analogue lines stop working on 31 January 2027, so monitored alarms need IP or mobile signalling.

How intruder alarm monitoring works
- Survey. Your system surveyed and nominated keyholders agreed.
- Connection. The alarm is linked to a 24-hour alarm receiving centre.
- Activation. When the alarm triggers, a signal goes to the ARC.
- Verification. Trained operators assess and verify the alert before taking action.
- Response. Nominated keyholders contacted, or emergency services alerted where appropriate.
- Maintenance. Routine servicing keeps the system reliable and false alarms down.

Intruder Alarm Monitoring FAQs
How does intruder alarm monitoring work? >
When the alarm system is triggered, a signal is sent to an Alarm Receiving Centre. Trained operators review the alert and take appropriate action, such as contacting keyholders or escalating the response if needed.
What is the difference between a monitored and an unmonitored alarm? >
A monitored alarm is connected to a remote centre that manages alerts and responses. An unmonitored alarm only sounds locally and relies on someone nearby to respond.
Can intruder alarm monitoring contact emergency services? >
Yes. If an alarm is verified and meets the required criteria, the monitoring centre can contact emergency services as part of the response process.
Is monitoring suitable for all types of business premises? >
Yes. Intruder alarm monitoring is suitable for a wide range of premises, including offices, retail spaces, warehouses, and industrial sites, particularly where security is needed outside of working hours.
What happens if an alarm is triggered by a false activation? >
If an alarm is identified as a false activation, operators can stand down the alert and contact keyholders if required. Verification processes help reduce unnecessary responses.
