So I just armed the 2gig for the first time this weekend. I set it on away and we left. I opened the door upon returning and the motion sensor caught me and immediately started sounding the alarm with no delay. I set it again and got the same results.

I currently do not have any door sensors. They were defective and I had to return them. Did the alarm go off becuase the motion sensor was triggered without a door sensor being triggered first?
