Abstract

An override mechanism is for a lock assembly including a movable latch, a retractor for displacing the latch, first and second rotatable spindles for operating the retractor, and an electronic clutch with a movable member for releasably connecting the first and second spindles. The override mechanism includes an override member movable between an inoperative position and an operative position and configured to displace the clutch member so as to connect the first and second spindles when the override member displaces from the inoperative position toward the operative position. A deadlatch is movable between a latching position and a nonlatching position and is configured to releasably retain the override member at the inoperative position when the deadlatch is disposed at the latching position. Preferably, an actuator is configured to displace the override member between the inoperative and operative positions and to alternatively retain the deadlatch at the latching position.
