A lock assembly (20) including a lock bolt (28), a first hub (36), a first electrically powered hub locker assembly (64, 66, 68 etc.) and a manually driven hub locker assembly (84, 86, 90 etc.). The lock bolt (28) is movable between a latching position and an unlatching position. The first hub (36) is adapted to move the lock bolt (28) in response to movement of a first handle. The first electrically powered hub locker assembly (64, 66, 68 etc.) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the first handle and is configurable for fail safe operation. The manually driven hub locker assembly (84, 86, 90 etc.) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the first handle. |
