ABSTRACT:
An automatic door opening safety system particularly for use with garage doors is provided. The garage door includes a leading edge that moves from the open position, where the leading edge defines the top of the opening and a closed position, where the leading edge contacts the ground. A controller is provided for controlling movement of the door. An activation member provides an input to the controller to initiate movement of the door. A non-contact detector detects whether an obstruction is in the path of the door. The non-contact detector is positioned in front of the leading edge of the door, such that obstructions are detected at a predetermined distance in front of the leading edge of said door.
