I currently rent a home that has ADT installed in it but that is not turned on. I contacted ADT and to get it turned on I have to sign up for a 3 year contract. This is something I do not want to do as my wife and I plan on buying a home in the next 2 years. I know that this contract can be carried over but I'm not sure if I will have money for this after I move. So this is not a commitment I want to make right now. Here is my question. My parents house also use to be monitored by ADT. Several years ago they stopped the service and not longer have ADT monitor their house. However the alarm in their house still seems to function for all practical purposes. Yes, I understand that no one is monitoring it but other then that it still works just the same as it did before. They can still set the alarm, the timer still works, and if they don't get to it in time then the siren gos off inside the house. They treat the alarm just like any hardwired system that you install yourself. Why does the ADT alarm in the house I am renting not function in the same manner? Is there anyway to turn it on just as a home alarm?
