You have a loose connection on your keybus.  You also have a low battery
(judging from your comments about unplugging the AC "overnight" without
removing a battery lead.  Take a screwdriver (small jewelry size) and
make sure all the terminals are tight and that no wires have come loose.
  You'll need access to the common control cabinet.  Hopefully you're
NOT monitored, but if you are you should call your monitoring station
before you start mucking about with the control (or your servicing company).
