We had our 1st alarm system in 1993 and over the years had it serviced by Young Alarms . Wright Security and then the very expensive Initial. We then went without service for years until the system went wrong and we were without a maintainer we had not used the thing for years but after a power cut we could not switch it off. We contacted 1st Alarms and they repaired the system and got it back into full working order , we changed the external sounder and battery but that was all that was needed. Great service and we are very thankful, this is a firm you can trust
