What is intruder alarm monitoring?

Intruder alarm monitoring links your alarm system to a dedicated, accredited Alarm Receiving Centre (ARC).

Turn detection into decisive action

Mitie Fire & Security delivers accredited intruder alarm monitoring services designed for resilience, compliance and real-world risk.

Secure signalling and dual-path resilience

Alarm signals must reach the ARC without interruption. We support graded signalling solutions including:

Dual-path systems use two independent transmission routes. If one fails, the second maintains connectivity — reducing vulnerability and supporting higher insurance grades.

Designed for system grading and compliance

Monitoring must align with intruder alarm grading requirements under PD 6662 and BS EN 50131.

We support:

Correct grading ensures compliance with insurer expectations and police response criteria.

FAQ: Intruder Alarm Monitoring

What standards apply to intruder alarm monitoring?

Monitoring centres should comply with BS 5979 or BS EN 50518 and be NSI approved. Alarm systems must align with PD 6662 and BS EN 50131 for grading and police response eligibility.

Dual-path signalling uses two independent communication routes (such as IP and GSM) to transmit alarm signals. If one path fails, the second maintains connectivity.

A Unique Reference Number (URN) is issued by police to qualifying monitored intruder alarm systems. It enables eligible police response when confirmed activations occur.

Yes. Confirmed alarm technologies such as sequential detection and visual verification reduce false activations and support accurate response.
