Lock system and lock having two electronic control systems

摘要

A lock (1) is mounted to a door (2) of a safe. The lock (1) comprises a housing (4) slidably mounted to the door (1) and movable in the directions indicated by an arrow (3) between locked and unlocked positions upon actuation of the lock. A lock override system (15) is coupled with the lock (1) and is responsive to an override control signal to cause the housing (4) to move relatively to the door and thereby to cause the lock member (8) to move between its locked and unlocked positions.
