In almost all cases CTB alarms can repair a broken or faulty Visonic Alarm System. Our Visonic Alarm Repair Engineers are highly trained in fault finding and diagnostics for all Visonic products. We carry Visonic spare parts for most common faults and often a repair can be completed in the same visit. Our alarm repair skills are not just limited to Visonic Alarms, we can diagnose faults for any type of alarm from a wide variety of alarm manufacturers. Your alarm does not need to have been originally installed by CTB Alarms for us to service or repair it. We can help with an alarm fault even if it has been installed by another company or by you.
