ABSTRACT:
A sensing apparatus for use with an automatic door operator and operator control logic responsive to door control signals for controlling the opening and closing operations of a swinging door is disclosed. The disclosed apparatus includes a plurality of infrared emitters and corresponding detectors on each side of the door which are recessed in the muntin of the door and which direct radiant energy and sense reflected radiant energy in selected detection zones which are determined at various positions of the door. Control logic connected to the detectors generates appropriate door control signals. The control logic is also responsive to door position signals generated by operator control logic to automatically vary the emission and detection levels of the emitters and detectors as the door opens and closes.
