1.
Prepare the door using the Q90 reader installation template or drill fixture. The door edge prep is a standard,
full-mortise prep for a 1-1/4” x 8” front plate (1” x 8” and 1” x 7-3/4” custom front plates are optional). The door
surface holes and mortise are customized for the Q90 trim.
Important:
Some holes are only on the inside surface of the door. See the door prep template.
• For new construction installations, the door manufacturer may prepare the door using the
installation template.
• For retrofit installations, remove the existing hardware and confirm that the existing door
edge prep is appropriate for the Q90 mortise lock.
Drill fixture: If you are using a Q90 drill fixture, position and clamp the fixture on the door. The fixture has two
positioning posts that rest inside the mortise, establishing the proper backset for the trim. When the fixture is
clamped, its surfaces should be parallel with the door surfaces and door edges. Not all holes go through the
door (refer to the template). Notch the material on the inside surface for easier routing of the motor wire. After
machining, remove any debris from the mortise and cutouts.
2.
Prepare the door frame using the template and install the strike plate using the screws provided
(12 x 1-1/2 screws for wood frames, 12-24 x 3/8 screws for metal frames).
