I installed the instrument yesterday and having following issues:
1. I set the system to "away" with 1 door with the sensor open. The base gives me a warning that 1 door is open but it still finally says system armed. What? When the door is open still system is armed.
2. Secondly if I try to do this with my iphone mobile app - the app does even worse no message and says system armed.
Are there any settings that I am missing. My ADT will never arm if one of the door with sensor is open.
