Installation:
1.
Measure the latch line (see fig. 1).
a.
Measure the distance between the face of
the door jamb and the face of the door latch.
This is the vertical latch distance.
b.
Measure the vertical latch distance on the
door jamb from the face of the door jamb. At
that point, draw a vertical line. This is the
latch line.
2.
Measure the center line (see fig. 2).
a.
Measure the distance from the floor to the
center of the door latch. Ignore the location
of the deadlatch pin when taking
measurements.
b.
Measure the same distance as above along
the inside of the door jamb. This is the
center line.
3.
Align the included mounting template to the latch
and center lines (see fig. 3)
4.
Using the template as a guide, cut into the door
jamb to a depth of
11
/
16
" (17mm).
NOTE:
If cutting into a wooden door, use a chisel
to knock out a
1
/
8
" (3mm) deep cut as shown on
the template.
5.
Using two of the included small screws (M4x12)
and black clips, affix the mounting tabs to the
inside of the door jamb (see fig. 4).
6.
Program fail-safe or fail secure (default – fail
secure, see "Programming for Fail-Safe or Fail-
Secure on page 4).
7.
Connect the two wires to the access control or
egress device, e.g. keypad, push-button switch,
push-bar, etc. using the provided electrical
connectors. Polarity is not important. Ensure that
no bare wiring is exposed.
8.
Conceal all wires in the door frame. Adjust trim
plate to cover any gaps in installation. Use two of
the included large screws (M5x12) to mount the
unit to the mounting tabs. Adjust as needed to
ensure the door closes smoothly (see fig.5).
