What is intruder alarm monitoring?

Intruder alarm monitoring links your on-site alarm to an accredited alarm receiving centre. When an alarm activates, a secure signal is sent instantly to trained operators who follow a pre-agreed response plan, contacting key holders, dispatching security, or escalating to police where appropriate. The result is rapid response, reduced risk, and peace of mind, even when your premises are unoccupied.

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for intruder alarm monitoring systems.

Accredited ARC connection and resilient signalling

We connect your system to an accredited alarm receiving centre using secure, dual-path signalling. If one communication route fails, the second takes over, maintaining continuous protection.

Tailored response protocols

We agree clear procedures for alarm activations, including key holder contact, security attendance, and police escalation. Protocols can be updated as your operations change.

24/7 monitoring and faster escalation

Round-the-clock monitoring ensures immediate action at any time. Where eligible, we support enhanced escalation pathways to help speed up police response.

False alarm filtering and clear reporting

Operators verify and filter unwanted activations, reducing disruption and cost. You receive concise incident reports for every activation to support audits and insurer requirements.

Integration with site systems

Monitoring can be linked with CCTV and access control for visual verification and smarter incident handling. This improves decision-making and supports coordinated responses.

Planned testing and maintenance

We provide routine checks of signalling integrity and system health. Regular servicing keeps performance reliable and supports compliance with insurer and industry standards.

Your questions answered.

  • Monitored alarms send activations to a live centre for immediate action. Non-monitored alarms rely on local sounders, which may go unheard out of hours.

  • It uses two independent communication routes. If one fails due to a fault or tampering, the other path still delivers the alarm signal.

  • Yes. Operators verify events and follow your protocol only when required, which lowers unnecessary call-outs and disruption.

  • Insurers often require monitored systems in commercial settings. Monitoring, clear records, and routine tests can support policy conditions and may reduce premiums.

  • Your panel sends a secure signal to the ARC. Operators follow your agreed plan, notifying key holders and, where applicable, requesting police attendance.

  • In many cases, yes. We can survey your current installation, upgrade signalling if needed, and migrate to our monitoring service with minimal downtime.
