Abstract:
Controlling movable barrier movement with respect to selectively overriding a safety system includes determining whether a safety system is in an operation failure or misalignment state, the safety system being configured to detect obstruction in a path of movement of a movable barrier, receiving a state change request for the movable barrier while the safety system is in the operation failure or misalignment state, determining whether a safety override condition exists, and overriding the safety system and actuating the movable barrier if the safety system is in the operation failure or misalignment state and the safety override condition exists.
