An electrically operated folding operable wall controlled by at least one control panel, an extend limit switch, a stack limit switch, control relays and a motor, in which the invention being a safety system comprises:
- a) a maintenance detecting means electrically connected to the control panel of the electrical operation circuit for detecting that required maintenance has been performed;
- b) a time measuring means for measuring time since the electrically operated folding operable wall was last serviced, wherein the time measuring means is electrically connected between the control panel of the electrical operation circuit and the maintenance detecting means;
- c) a first time alarm means for detecting that the time measured by the time measuring means has reached a first preset time for a maintenance reminder, wherein the first time alarm means is electrically connected between the control panel of the electrical operation circuit and the time measuring means;
- d) a second time alarm means for detecting that the time measured by the time measuring means has reached a second preset time for maintenance, wherein the second time alarm means is electrically connected between the control panel of the electrical operation circuit and the time measuring means;
- e) a first maintenance schedule indicator electrically connected between the control panel of the electrical operation circuit and the first time alarm means for generating and displaying a warning indicating that maintenance is soon required on a display means when the first time alarm means detects that the time the electrically operated folding operable wall was last serviced has reached the preset time for a maintenance reminder;
- f) a second maintenance schedule indicator electrically connected between the control panel of the electrical operation circuit and the second time alarm means for generating and displaying an instruction indicating that maintenance is required on the display means when the second time alarm means detects that the time the electrically operated folding operable wall was last serviced has reached the preset time for maintenance;
- 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 preset time for maintenance, wherein the preventing means includes at least one control unit electrically connected between each control panel of the electrical operation circuit and the second time alarm means, which will prevent the control unit from functioning if the second time alarm detects that the time measuring means has reached the preset time for maintenance;
- h) a resetting means electrically connected between the control panel of the electrical operation circuit and the maintenance detecting means for resetting the time measured by the time measuring means, when the maintenance detecting means detects that the required maintenance has been performed;
- and
- i) a restarting means for restarting the electrical operation circuit of the folding operable wall after the maintenance detecting means detects that required service has been performed, wherein the restarting means includes a reset control key switch in the at least one control unit, which when turned on will reactivate the electrical operation circuit.
