    Abstract: A door assembly may include a first sidelite configured to be operably coupled to a first door jamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and defining a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, and are disposed in a second plane parallel to the common plane in both the open and closed position, a first partial door panel disposed in a third plane opposite the second plate relative to the common plane, and a second partial door panel disposed in the third plane, the first and second partial door panel being movable from being a closed state in which the first and second partial door panels at least partially block access through the door opening and an open state in which the first partial door panel is proximate the first sidelite and the second partial door panel is proximate the second sidelite. The first and second partial door panels are each operably coupled to a biasing assembly that biases the first and second partial door panels toward the open state, and the first and second partial door panels are configured to be transitioned to the closed state by manual operation against a force of the biasing assembly.
