Intruders Alarms

Intruder alarms offer 24/7 protection, offering peace of mind to both occupiers and building managers during periods of vacancy.

From basic intruder systems to fully bespoke or integrated technology, A Plus Security specialise in design, installation, maintenance, and post-project support.

Intruder systems can be remotely monitored and integrated with third party systems (such as CCTV and access control) to maximise protection for high security premises.

Our extensive marketplace expertise will determine which grade of system is fit for purpose, depending on individual building requirements and risk assessment outcome.


Will the alarm alert the police?

Yes. In the instance of activation, a police-assigned Unique Reference Number (URN) will raise an alarm to the police.

Can the alarm be externally monitored?

Yes, it is common practice for intruder alarm systems to be monitored remotely by an Alarm Receiving Centre (ARC). This is usually set up at the start of installation. The designated keyholder will be alerted during any confirmed alarm activation.

A ‘bells only’ alarm can also be activated, which emits a local noise to deter current intrusion taking place.

Will the alarm need to be maintained?

A maintenance agreement is highly recommended, to ensure the system is performing optimally, all year round. As faulty systems can raise false alarms, it’s important to maintain strong police response times by ensuring that the alarm is only activated during genuine events.

Do you offer intruder alarm maintenance

Yes. We offer a 6-monthly visit to test and log the performance of all devices, batteries, and critical functions to provide peace of mind that the system is functioning highly 27/4.

If you happen to be locked into a maintenance contract with another supplier with which you are not satisfied with, then we’ll make it easy for you to switch to us.

What other
clients have to
say about us

A Plus provides an excellent return on investment, not just through the solution installed, but the general experience they offer from pre-install to post-install and right through to the maintenance of the system. We knew we had made the right decision with A Plus as they offered a comprehensive and detailed proposal and project plan. The skill level of their engineers was a pleasant surprise with their knowledge of IT and networks, as well as electronic security, which made dealing with our internal IT team very smooth. Apart from that, the fact we never had to chase them for anything was a very nice surprise!

We needed to roll out the new system throughout Scotland, London and Europe which was very challenging. A Plus and their advice and flexibility made this process much easier for the whole project team. The one to one dialogue and personal service has been excellent. We can speak to a familiar voice at any time, morning and night which has exceeded our expectations. Since the project roll out was completed, we have been able to centrally control the physical security of the Government’s Estates seamlessly. The process Is now simpler which has led to better productivity.
