Twenty three years ago I built a new home. The builder had a contract with ADT to install an alarm system. ADT installed the wiring and a control unit but then closed their offices here and left town. I called Global Alarm and told them I was in a bind. They said, no problem, we will be out tomorrow. They have handled everything that has ever happened for all this time. They are the best and fun to work with as well. I highly recommend them to take care of your security needs!
