An exemplary method includes operating an access control device including a bolt, an output gear having a magnet mounted thereon, a first magnetic sensor, and a second magnetic sensor. The method generally includes selectively determining a position of the output gear via one of the first magnetic sensor or the second magnetic sensor based upon a current handedness of the access control device. With the access control device in a first handing configuration, the first magnetic sensor may be used to a first handedness first home position of the output gear. With the access control device in a second handing configuration, the second magnetic sensor may be utilized to detect a second handedness first home position of the output gear.

Bolt actuation assembly

An exemplary method generally relates to operating an access control device including a motor, a locking member, and a target component operably connected with the locking member. The motor may be operated to drive the locking member in a first direction from an initial position toward a desired position. When the locking member is blocked from moving beyond a blockage position, a target location of the target component is detected. The motor may then be operated to drive the locking member in a second direction opposite the first direction. The motor may then be operated to drive the locking member in the first direction toward the blockage position while monitoring the location of the target component. As the target component reaches the target location, the motor is supplied with a boost current to drive the locking member beyond the blockage position and toward the desired position.

Sensing and control of access control devices

A lockset including a bolt mechanism, an exterior assembly, an interior assembly, a driving tailpiece, and a driven tailpiece. The bolt assembly includes a bolt having an extended position and a retracted position. The exterior assembly includes a rotatable exterior manual actuator. The interior assembly includes a clutch having a coupling state and a decoupling state. The driving tailpiece is connected between the exterior manual actuator and the clutch. The driven tailpiece is connected between the clutch and the bolt mechanism such that rotation of the driven tailpiece actuates the bolt assembly. In the coupling state, the clutch couples the driving tailpiece with the driven tailpiece such that the exterior manual actuator is operable to actuate the bolt assembly. In the decoupling state, the clutch decouples the driving tailpiece from the driven tailpiece such that the exterior manual actuator is inoperable to actuate the bolt assembly.
