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 our
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!

International Group of Schools

We chose A-Plus Security to carry out the upgrade of our electronic security systems for our 9 colleges and they have far exceeded our expectations in their approach to the projects. We are a UK wide organisation where the planning and mobilising of these major project around term times is time critical and A Plus Security have been nothing short of fantastic in the communication, there design proposals, openness to last minute changes, pre and post-sales support and their management of 3rd party companies and IT services. We would highly recommend A Plus Security to any organisation who are looking to install or upgrade their systems.

Nationwide Groups of Colleges

A Plus Security exceeded all expectations, following a late award of the contract due to a different contractor pulling out. All fire and security works were completed when requested and signed off on finish, with no issues noted. We have continued working with A Plus on following projects and would fully recommend them.
