Can't set alarm due to fault in bedroom. called installer, no joy.
Technician was very helpful, answered all questions and was very patient.
I was oversold when I acquired ADT services. The glass cracking devices cost me almost $1500. Their price to me was significantly higher than published ads and mailers. The glass cracking devices sound the alarm if you sneez and/or drop the soap in the shower. I may recommend them but not to my friends.
