1-20. (canceled)
A mortise lock assembly, comprising:
- an in-door mortise casing assembly including a deadbolt assembly and a latch assembly;
- a handle assembly, including an interior handle to be operably coupled to a latch of the latch assembly to selectively retract the latch and an exterior handle operative to be operably coupled to the latch to selective retract the latch, and when the handles are operably coupled to the latch and a deadbolt of the deadbolt assembly is in an extended position at least one of the interior and exterior handles is locked;
- a thumb turn assembly including a manual thumb turn to be provided on an interior side of the door and operatively coupled to the deadbolt to selectively move the deadbolt between the extended position and a retracted position;
- a motor operatively coupled to the deadbolt to selectively move the deadbolt between the extended position and a retracted position;
- and
- a communications system communicatively coupled to the motor to receive an instruction from a user and direct an operation of the motor in response to the instruction from the user.
The mortise lock assembly of claim 34, wherein one of the first and second positions is a retracted position and the other of the first and second position is an extended position in which a distal end of lock position indicator is moved farther from a main body of the interior housing than in the one of the first and second positions.
The mortise lock assembly of claim 39, further comprising a communication cable operable to extend through the door to communicatively couple the exterior housing with an interior housing mounted to the interior side of the door and containing the motor.
A method of installing the mortise lock assembly of claim 40, including mounting the interior housing to the interior side of the door, mounting the exterior housing to the exterior side of the door, and passing the communications cable through the door to couple the interior and exterior housings, wherein the communications cable coupling the interior and exterior housings bypasses the in-door mortise casing assembly.
