Abstract
An exemplary trim lock device is configured for use with a trim comprising a lift finger, and generally includes a housing, a blocking member, and a lock actuator. The blocking member includes a projection, and is rotatably mounted to the housing for rotation between a blocking position in which the projection blocks actuating movement of the lift finger and an unblocking position in which the blocking member does not block actuating movement of the lift finger. The lock actuator is operable to rotate the blocking member between the blocking position and the unblocking position.
