Abstract
A door lock system includes a shaft and a cam. The cam is supported on the shaft for rotation with the shaft, and for movement along the shaft throughout a range of door lock release locations. A selector engages the cam to move the cam along the shaft upon rotation of the selector. An actuator lock has a closed condition blocking rotation of the shaft, and has an open condition permitting rotation of the shaft. The actuator lock prevents rotation of the cam at any of the door lock release locations when the actuator lock is in the closed condition.
