Installation Instructions
Step 1: Prep Door
Use the plastic template to mark the trim holes. Ensure the LHR (Left Hand Reverse) orientation is correct if applicable. Align the plastic template LOCK CENTERLINE with the mark previously made. Mark the four mounting locations and the 03 INPUT location. Drill a 1-1/4 inch diameter hole through the trim side only, and four 3/8 inch diameter holes through the trim side only.
Step 2: Install Trim
Install the backplate using the four 1/4-20 x 1 inch long screws and lockwashers provided with the exit device.
Step 3: Install Mortise Lock
Install the mortise lock and mounting hardware provided with the exit device. Fasten the hardware loosely. Use 12-24 x 1/2 inch screws for metal doors or #12 x 1 inch screws for wood doors.
Step 4: Install Mortise Cylinder
Insert the mortise cylinder and turn it clockwise (CW) to install.
Step 5: Secure Cylinder
Tighten the screws (referenced in step 3) to secure the assembly. Tighten the screw nearest the trim side of the door only. Continue the installation using the specific device instructions.
