We design our systems to detect any intruders at the earliest possible point, to protect the most valuable people in your life.


Built with you in mind

GCS Alarms supply and install a wide range of intruder systems from small domestic systems to large industrial systems. The alarm system is designed to be wired, wireless or a combination of both depending on the premises type or the customers’ requirements. Since each system is tailored to each customer and each budget, the system required may consist of a number of elements including motion detectors and door sensors, which are controlled via a main control panel. We use trusted suppliers and wholesalers for all the equipment that we use.

Greg and his team have done work for us at a few different sites recently. The engineering staff that carried out the installation were efficient, professional and friendly.

Thanks for sending out the engineer so quickly. Overall thanks for all the work that was done, the support was great. I would recommend.
I have been involved with GCS Alarms on a large number of projects and I would highly recommend them for their first class service and attention to detail.

Intruder alarm servicing

Most intruder alarms should be serviced during their life time. Minor faults, battery faults or other faults need to be serviced before it becomes problematic. Your intruder alarm protects your home and your family.
