摘要:
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.
