Ralph, Security Systems as we know have come along way over the years. The "glass break" or "open" sensors are what I believe you're speaking of. We use the ADT Pulse systems because of System functionality and how it operates.  My Previous Career Experiances are in Militarty EOD ( Bomb Squad) operations to include Advaced training in access and Denial Training/ operations  of each system and sensors. So my answer is based solely on the specific question answered. 1. Bruce is Spot on about warranty checks although I would add that ADT would more than Likly come out and reinstall or update at little to no cost and there functionality to me is key and they would be the ones with the experiace and structure to validate. From an Experiance base answer I would suggest looking possibly at updating to a Pulse style system or aka Smart home system that allows Video and active security measures. The importance of the installer or service provider being the installer  is based on the " durning Need time frame". knowing your system is set right is piece of mind and could be life saving.  Active motion sensor lights | IR and Proximity sensors inside | And a HOME setting for perimeter security are good standards of practice. Gavigan Homes
