Andy assessed our home and guided us 25 years ago with our original installation. The service then was professional and the product has been totally reliable throughout. I decided an upgrade was called for, even though the original product was still in good working order. Enjoyed a similar professional experience again this time. Andy was most helpful as were Richard and Steve who installed the upgraded system. Recommended AAI to my children in their new homes. They have also received the same level of care and attention. Can totally recommend AAI for a professional and practical alarm solution. Thanks you AAI
