I am using 3 of theDM10A motion sensors all around the outside of my house, I have them linked to a SC546A chime, Lately it keeps going off every few minutes for no reason at all. I have replaced all the batteries in the sensors just in case and I sit out there and watch them to see if the red light inside comes on but nothing.
What could be causing this and what would remedy this problem?
Thanks in advance,
Denny
