I have an ADT installed (years ago) alarm system with an Ademco control box (I don't have the details in front of me). It has been flashing 13 for a while and won't let me arm the system. I figured out that that corresponds to a wireless infrared sensor by my front door. I changed the batteries in it and that didn't help. Also, when I opened the case, it didn't beep on the control panel like it normally wuld. I am guessing the sensor has gone bad. My questions are:
1) Is there any way to confirm this without getting anew sensor? 2) Is there anyway to just disable that sensor so I can arm the system?My knowledge of this system is pretty limited....
