Electrically operated folding operable walls controlled by an electrical operation circuit of the type having a key switch, a control panel, an extend limit, a stack limit, control relays and a motor. The invention consists of a mechanism designed to provide safety during the operation of said folding walls by sensing a person or object with a lead edge sensor, floor mat sensors, and a wireless transmitter and receiver assembly that, when wired to the folding wall control panel, will shut down the operation of the folding wall. Another mechanism provides for the restarting of the folding wall by resetting the relay inside the control panel.
