An electrically operated folding operable wall is controlled by an electrical operation circuit of the type having at least one control station, an extend control switch, a stack control switch, control relays and a motor. The electrically operated folding operable wall includes a safety system which includes (a) at least one touch sensor selectively responsive to an electrical characteristic of a human body and actuated by operative contact of the human body therewith; and, (b) means for preventing the electrical operation circuit of the folding operable wall from functioning if the touch sensor is not actuated. The preventing means includes at least one control unit electrically connected between each control station of the electrical operation circuit and each touch sensor, which will prevent the control station from functioning if the touch sensor is not actuated by contact with a human body. |
