A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in a closed orientation and an open orientation. The latching assembly includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked and an unlocked position. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions. The actuatable lock assembly includes a catch member that is configured to pivot about a pivot axle, wherein the latch controls the pivoting of the catch member, selectively precluding and allowing the same.

A sliding door latch system and method is disclosed herein. The sliding door latch system is used to prevent movement of a sliding door between a closed position and an open position relative to a fixed door frame. The device may be installed as a secondary safety latch on a sliding door having a primary latch that is located at an elevation within the reach of the child. The device may be installed at an elevation above the reach of the child, but readily within the reach of an adult user. The sliding door latch includes a latch arm located outside the sliding door to simplify installation. The latch arm is user-locatable in a latched position, a momentarily released position, and a held-in-release position.

A method for operating a lockset generally includes transmitting an unlock command to an electronic actuator in response to receiving an unlock signal. In response to receiving the unlock command, the electronic actuator performs a first operation, including moving a holdback from a release position to a hold position. In response to actuation of a manual actuator, a latchbolt is moved from an extended position to a retracted position. The holdback in the hold position retains the latchbolt in the retracted position.

A latch dogging assembly comprises an electromagnet and an actuator mounted on a bracket. A guide slide is pivotally mounted on the bracket with a lead block coupled to the guide slide. A guide pin rides along an inner surface of the bracket causing the guide slide to pivot. A pawl is slidably engaged with the guide slide. A guide link includes a post. An armature is mounted to the panic bar and the post engages the pawl. When the actuator is energized to move the lead block, the pawl engages the post to pivot the armature and thereby cause the panic bar to move from the extended position to the depressed position. When the electromagnet is energized the armature is magnetically held preventing reverse pivoting of the guide link. A method for fully retracting a door latch is also provided.
