Claim:
A safety system for maintaining an electrically operated foldable wall having an electrical operation circuit with at least one control station, the system comprising: (a) a maintenance detecting means for detecting whether maintenance has been performed on the electrically operated foldable wall; (b) a time measuring means for measuring time since the electrically operated foldable wall was last serviced; (c) a first time alarm means for detecting a first preset time for a maintenance reminder; (d) a second time alarm means for detecting a second preset time for maintenance; (e) a first maintenance schedule indicator for providing a maintenance reminder that maintenance is soon required; (f) a second maintenance schedule indicator for indicating that maintenance is presently required; (g) a preventing means for preventing the electrical operation circuit of the folding operable wall from functioning after the second time alarm detects that the time measuring means has reached the second preset time for maintenance; (h) a resetting means for resetting the time measured by the time measuring means after the required maintenance has been performed; and (i) a restarting means for restarting the electrical operation circuit of the folding operable wall after the required service has been performed.
