Intruder Alarms

Intruder alarms to deter burglars, alert police and satisfy insurers

From providing a visual deterrent through to activating an urgent police response, our intruder alarm systems give your organisation the right level of protection against break-ins.

After a free security assessment of your premises, we will recommend an appropriate grade of intruder alarm for your needs, including the requirements of your insurance policies and the standards required for automatic police or garda response. We carry out hard-wired and wireless alarm installations – whichever makes sense in your premises.


We have direct relationships with all of the major intruder alarm manufacturers, but we are not tied to any of them. We will install the right alarm for your premises, always to BS8243, PD6662, EN5013-1, BSEN ISO 9001:2000 standards and in accordance with the National Security Inspectorate (NSI) NACOSS Codes of Practice.


Intruder alarm monitoring on your terms

We offer a wide range of intruder alarm monitoring services, so you can plan the best response if your alarm goes off. Self-monitor your alarm via a phone app or let our alarm receiving centre (ARC) take care of it for you, with immediate alerts to keyholders or police.

We monitor intruder alarms for large commercial security operations, as well as more than 500 home intruder alarm systems in Northern Ireland.


Reliable intruder alarm servicing and support

Since we install all major intruder alarm brands, our experienced engineers can also service and support them. From planned maintenance to 24-hour, 365 days-a-year emergency support covering all of Ireland, our trained engineers will be there when you need them.
