Abstract
A deadbolt locking actuator includes a housing mounting a reversible motor. A worm is fitted on an output shaft of the motor and meshed with a worm gear. A rotary arm is provided outside of the housing and coupled to the worm gear. A pin on the rotary arm is received in an elongated slot of a link connected to a manual locking lever of a door latch. A control circuit operates the drive unit and link between deadbolt and non-deadbolt positions.
