Abstract:
A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member.
