ADT safewatch 3000 OC display

All of a sudden I recieved and OC display on both of my units. Nothing has changed. Checked wiring and everything is fine. What else can I do?

Losing both keypads like that, especially if both are homerun back to the main panel terminals is not a good sign. It means that the keypad is getting power, but no data is being seen from the main control.

Try taking one of the keypads to the main control location, and connecting it right at the keypad buss with known good wire. If you works there, then the only thing left is damaged cables between the main panel and the keypads.
