Abstract
An access device for a materials depository includes a panel member having opposing front and rear faces with a return aperture disposed therethrough, a door having size dimensions capable of fully blocking the return aperture, and a door actuator coupled to the door for causing the door, in response to a command signal, to selectively slide between a blocking position where the return aperture is blocked by the door, and an unblocking position where the return aperture is not blocked by the door. The access device also includes a materials sensor for providing a materials alarm signal that is indicative of a presence of materials intended to be passed through the return aperture. The access device further includes a control system that is responsive to the materials alarm signal, for providing the command signal.
