4. Position the strike against the door frame and align it with
the mounting screw holes. Trace the outline of the strike.
5. Remove material from within the strike outline so that the
strike will be flush with the door frame.
6. For ASM, install the dust box (optional for wood door
frames, required for metal door frames), and check the
strike handing on the template. For ASM and ESM install
the strike using the screws provided. Use wood screws for
wood frames and machined screws for steel frames.
CAUTION
WARNING
IMPORTANT
When strike is installed on wood frames under one inch thick,
wood screws supplied are not adequate. use screws of effi-
cient length to engage the structural stud behind the frame.
Use only the strike and dust box supplied. Use of non-ap-
proved parts may void the warranty.
3 Installation of Standard ASM or ESM Models
(for cylindrical see Appendix B)
3.2 Install the Strike
1. Align the paper template on the door frame at the desired
handle height ( ), and along the vertical center line of
the mortise (CL), which is also the center line of the door
edge, allowing for any bumpers on the door frame.
CAUTION
WARNING
IMPORTANT
Respect applicable building codes regarding handle height.
Note that the centerline of an ESMmortise does NOT pass
through the screw holes on the strike.
(CL)
2. Mark the locations of the dust box cutout and mounting
screws for the strike.
3. Create the dust box pocket and chisel out the strike contour
in the door frame, and drill the pilot holes for the mounting
screws (dimensions and depths marked on template).

3.3 Install the Mortise (for cylindrical, see Appendix B)
CAUTION
WARNING
IMPORTANT
If using the installation jig to pre-
pare the door, refer to the instruc-
tions provided with the jig, then
proceed with step 4 below.
1. Mark the handle ( ) height
on the edge of the door, as de-
termined directly from the
strike.
For ASM, the axis of rotation of
the handle is level with the bottom
lip of the strike.
For ESM, the axis of rotation of
the handle is 1⁄" above the bot-
tom lip of the strike.
2. Align the template along the
vertical center line of the mor-
tise (CL) at the desired handle
height, and tape it to the door. Mark all holes and cutouts
for the mortise in the edge of the door and remove the
template.

3. Locate the two sets of vertical fold lines on the template
allowing you to adjust the positioning of the template de-
pending on the bevel of the door.
If the door has no bevel, fold the template along the solid
lines. Align the fold with the edge of the door and mark the
holes for the lock. Repeat on the other side of the door.
If the door has a 3º bevel, fold and align the dashed line
marked “H" on the template with the higher-beveled edge
of the door and mark the lock holes on that side of the door.
Repeat on the side with the lower-beveled edge using the
dashed line marked “L". Remove the template.
4. Prepare the cut-outs for the mortise in the edge of the
door using a mortising machine, router and chisel (for di-
mensions, refer to template).
Ensure clearance is provided for moving latch parts as indi-
cated on the template.

5. Drill the holes in the sides of the door (for dimensions, refer
to template).
Drill from both sides of the door to prevent unsightly dam-
age.
6. For ASM only, check the bevel of the mortise. If adjust-
ment is required, loosen bevel screws (R) and adjust mor-
tise front plate angle to match the bevel of the door. Re-
tighten screws.
For models 79R, 79Z, 79Y, 79Q slide the ajar switch cable of
the mortise (V) through the hole at the top of the mortise
pocket. The cable must go through the outside of the door
for connection in the next step.

CAUTION
WARNING
IMPORTANT
Read the following instructions before using any of the 3 keys
supplied
The recodable cylinder can be operated with three different
keys. The keys are numbered 1, 2 & 3, and each key is labeled
and supplied in a separate plastic bag. It is very important to
use them in order.
* Always read the label instructions on the label before using
a key.
CAUTION
WARNING
IMPORTANT
The use of key #2 automatically cancels the function of key
#1, and the use of key #3 automatically cancels both keys #1
and #2.
If key #3 is used first, it will immediately make keys #1 and
#2 unusable.
Once a key is cancelled, it can’t be reactivated unless the cyl-
inder itself is re-pinned.
