Abstract: A closure system including a door mounted to open and close an entrance, a first object detector including a transmitter of radiant energy and a detector thereof, and a second object detector including a ribbon switch mounted on the edge of the door which leads upon closure thereof. A source of electrical potential energizes a translating device via the ribbon switch, until the ribbon is actuated, which deenergizes the translating device. The first object detector controls the operation of the door when an object interrupts radiant energy from the transmitter, and the translating device of the second detector controls the operation of the door when it is deenergized.
