Abstract
A door lock (10) includes a strike case (18) adapted to receive a dead bolt (14). A rotatable keeper (20) is rotatable between an open and closed position for opening and closing the strike case (18). An abutment member (30) is connected to the rotatable keeper (20) and is selectively rotatable with the rotatable keeper (20). A sensing arm (34) is connected to the strike case (18) for sensing the presence of the dead bolt (14) in the strike case (18). The sensing arm (34) selectively disengages the abutment member (30) for allowing the abutment member (30) to rotate with the rotatable keeper (20) if the dead bolt (14) is detected within the strike case (18).
