Installation

NOTE: Refer to local building standards and codes to verify that the installation will meet the regulatory

requirements. Observe all local and national building and safety codes, UL requirements, and ADA
accessibility guidelines.

Before installation identify the type of wall (masonry or non-masonry) and the location where the WMK 150 will be
installed. This determines the installation approach and type of fasteners needed to secure the plate to the wall.

1. Mount the Base Plate

Follow the steps within 1A or 1B, as applicable.

NOTE: The base plate can be installed over an existing

electrical outlet (see figure 2).

1A. To mount the WMK 150 onto masonry walls:

i. Hold the base against the wall, level it, and mark the

positions of four slotted mounting holes (indicated by
+ marks in figure 2). Set the plate aside.

ii. Using a masonry drill bit, drill 1¾ inch (4.4 cm) deep

pilot holes at the marked locations.

iii. Screw in ¼ x 1¾ inch masonry screws (not supplied)

until a gap of about 3/8 inch (9 mm) remains between
the wall and the screw heads.

iv. Align the slotted mounting holes of the base plate

over the installed screws, then slide the plate
down so the screws fit into the slots.

v. Verify level and position and tighten all the screws to

secure the plate flush to the wall.

Proceed to step 2.

PRELIMINARY

1B. To mount the WMK 150 onto a non-masonry wall:

i. At the desired site locate and mark the wall studs.

NOTE: For ideal installation secure the base plate to at

least one wall stud with two screws (see figure 3).
Drywall KapToggles can be used for holes not
aligned with studs.

Always use the widest spacing of screws and

KapToggles.
The base plate can be installed over an existing
electrical outlet (see figure 2).

the stud lines (see figure 3, indicated by + marks). Where
applicable, mark the mounting holes on the wall for
drywall toggles.

iii. If the cables are to be run behind the wall to the

WMK 150 location, mark the cutout area on the wall for
the signal cable access hole (see figure 3). Remove the base
plate and set the plate aside.

iv. Drill 1¾ inch (4.4 cm) deep pilot holes at the hole marks.
