摘要

An automated door latch actuator (10) that can interface with a standard door latch bolt assembly of a door, actuating both a spring latch bolt and dead latch bolt assemblies to retain the door in a fastened state. The automated door latch actuator (10) comprises a housing (16), a spring latch plunger (52), a dead latch plunger (54), a rotary drive including a motor (86), worm gear drive (84) and a crank (82). The spring latch plunger (52) and dead latch plunger (54) include slots (108, 110) for engaging the crank (82) to move the plungers (52, 54) into different positions. The method for an automated door latch actuator (10) consisting of sensing the secure or released state of the door latch assembly for automated monitoring and control.
