Re: AU2 Door Ajar
open the door, and using a phillips screwdriver, close the latch on the offending door to imitate it being closed.
See if the system works correctly.
If it does, reopen it and then close the door...does it close flush?
If not, then this is your problem....the striker plate in the door jamb is out of alignment...2 causes, either loose or some PERSON slammed the doors....something E series on Doors do not require if properly adjusted..unlike a crappodore
