Mike,

I don't know the answer to that. It was installed on the coach when I got it. It has switches to arm the "mikes" and "pressure mats". On my home alarm, the only time it has gone off was when we left and the girls had a helium balloon upstairs. When the AC came on, it caused it to move and the motion detector went off and the alarm company called me. I think I need a big barking dog alarm to go off inside when we are gone.
