Step 3:
(Illustration 3). Thread the bell wire through
completed hole from inside the garage. Fasten wire to
the Key Switch terminal screws before attaching
mounting plate to jamb. In most cases, 4 screw nails will
hold the plate firmly in place. Drive a nail into jamb and
wind some wire around it before running wire to the
opener terminals.
NOTE: Instructions for attaching bell wire to opener
terminals are on Page 2.
CAUTION: Bell wire should be pulled taut to prevent
access to wiring from outside the garage.
Step 2:
(Illustration 2). If your garage has a built-up jamb,
drill the hole to a depth of 2" (5 cm). Then on the inside
jamb, drill a second hole into the first hole to complete
access.

Position key Switch in the upper half of garage door jamb.
Mark the location on horizontal center of jamb or to a
depth of 2" (5 cm) (see Step 2).

illustration on page 2). If anchor and nut are used,
remove the Key Switch terminal screws.
Insert key Switch in drilled hole. Install anchor and nut.
Return screws to switch terminals. Fasten bell wire to
