Commercial Alarm Services

We support commercial intruder alarm systems at every stage, helping keep your premises protected.

A new intruder alarm system provides detection across key areas of your premises.

We carry out a site survey to assess risks, entry points, and system requirements. Equipment is selected to suit commercial use and installed with minimal disruption.

Once complete, the system is fully tested and handed over, so it is ready for day-to-day use.

Contact Us

If your intruder alarm is currently maintained by another provider, we can take over the system and provide ongoing support.

We carry out an initial inspection to assess the condition, performance, and compliance of the system. Any faults, limitations, or areas of concern are identified, with clear recommendations provided where required.

This allows the system to remain in place while moving to a new provider, with minimal disruption and improved reliability where needed.

Contact Us

If your current system is outdated or no longer reliable, upgrades can improve performance and compliance.

We assess the existing setup and recommend practical improvements. This may include updated control equipment, additional detection, or improved signalling.

Upgrades help reduce false alarms and keep the system in line with requirements.

Faults can affect system performance and leave areas unprotected.

We carry out fault finding to identify the cause, including detector issues, battery faults, wiring problems, or signalling errors. Repairs are completed to restore full operation.

This helps ensure the system continues to perform as expected.

Monitoring provides added protection when your premises are unattended.

The system can be connected to an Alarm Receiving Centre (ARC), where signals are monitored at all times. If activation occurs, agreed contacts are notified and action is taken in line with the response plan.

Regular maintenance helps keep the system operating correctly and in line with current standards.

During a service visit, we test detection devices, check standby batteries, review signalling, and confirm system performance. Records are updated after each visit to support compliance.

This helps reduce the risk of faults and unexpected issues.
