Abstract
An electronic locking system is provided wherein an electronic lock's restriction of movement of a locked securing member, such as a door latch or bolt, can be selectively overridden from inside a locked enclosure by manual manipulation of a handle. The handle moves the securing member to open a locked barrier even though the electronic lock remains in a locked condition.
