I have an Ademco keypad from an ADT installed security system. I longago dumped ADT. Anyway, it says "13 Check" on the display. The keypadis wired, but the rest of the system is wireless.I have only 3 door sensors and 2 motion sensors. All 3 doors beep whenI open them. The 2 motion detectors red light goes on when Iapproach. I am not sure what could be causing the "13 - Check". Thealarm seems to function just fine otherwise. Any ideas?Although I added 2 wireless keyfobs to the system myself, but I amotherwise fairly ignorant as to what system I have an details of thesetup.
