Abstract:
1. A method of autohanding an electromechanical door lock including a locking mechanism, the method comprising: installing the electromechanical lock in either a left hand configuration or a right hand configuration, the configuration being unknown to the door lock; sensing a first position of the locking mechanism; evaluating whether the configuration of the lock can be determined based upon the first position; setting the configuration of the lock if it can be determined based upon the first position; electronically actuating the locking mechanism in a first direction and monitoring for at least one predetermined position of the locking mechanism and for a motor stall indication if the configuration of the lock cannot be determined based upon the sensing; if the at least one predetermined position is detected setting the configuration of the lock based upon the at least one predetermined position; upon detection of the motor stall indication setting an error state or electronically actuating the locking mechanism in a second direction; if actuating the locking mechanism in the second direction monitoring for the at least one predetermined position of the locking mechanism and for the motor stall indication; and if the at least one predetermined position is sensed setting the configuration of the lock according to the at least one predetermined position.
