It means that the keypad cannot talk to the control. One or more of the wires either at the back of the keypad, or at the panel terminals is not connected. The worst case is the wire being damaged somewhere inbetween. Has any work been done on the system or the house? I've seen this happen from someone stepping through an attic and snagging the cable with their shoe (and then there's _squirrels_....)

Also make sure it is addressed correctly for your panel. 31 for most panels. If it is a p series(2op,15p) etc it depends on how many keypads you have and you have to enable individually in system programming then address at each keypad
