cm) enclosure, and a base plate on which to mount the switcher (for
example the PVS 405D) and the associated power supply, with room
for cable management.
In addition, an accessory device can be mounted on the base plate.
The cover has knockouts on three sides that allow external raceways
to be used where needed for cabling.

WMK 160
Base Plate
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 160 will be installed.
This determines the installation approach and type of fasteners needed to secure the plate to the wall.
Step 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 160 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 gure2). 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 t into the slots.
v. Verify level and position and tighten all the screws to secure
the plate ush to the wall.
Proceed to step 2.
1B. To mount the WMK 160 onto a non-masonry wall:
i. At the desired site, locate and mark the wall studs.
NOTES:
• For ideal installation secure the base plate to at least
one wall stud (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).
ii. Hold and level the base plate against the wall and mark
the positions of the slotted mounting holes that are on
the stud lines (see gure 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 160 location, mark the cutout area on the wall for
the signal cable access hole (see gure 3). Remove the base
plate and set the plate aside.
iv. Drill 1¾ inch (4.4 cm) deep pilot holes at the hole marks.
v. Cut out the marked area for cable access.
vi. At the pilot holes, screw in the screws until a gap of about
3/8 inch (9 mm) remains between the wall and the screw heads.

viii. Verify level and position, and tighten down all the
screws to secure the plate ush to the wall.
Step 2. — Mount the Switcher, Power Supply, and Accessory Device
NOTE: Always use a power supply supplied or specified by Extron. Use of an unauthorized power supply voids all
regulatory compliance certification and may cause damage to the supply and the end product. Unless otherwise stated,
the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The installation must always be
in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian
Electrical Code part 1, section 16. The power supply shall not be permanently fixed to a building structure or similar
structure.
a. Invert the switcher and place it (base up) on a at surface.
Place the mounting plate at on the switcher base with the plate
tabs (raised section up) over the edge of the front panel. Align the
two mounting holes in the switcher base with the corresponding
holes on the mounting plate. Secure the plate to the switcher with
the supplied 4-40 x ¼ inch screws.
b. Secure the switcher mounting plate (with switcher
attached) to the base plate by sliding the two tabs into
the slots at the bottom edge of the base plate. Secure to
the standoffs with 4-40 x 3/16 inch screws (see gure 5).
c. Secure the power supply to the right of the electrical outlet cutout
by threading the supplied tie wraps through the loops on the
base plate. Attach it so the cables are easily and safely routed
to the electrical outlet and switcher alike.
d. An optional ¼ rack, 3 inch deep accessory device, such as the
Extron IPL TS2, can be installed on the WMK 160 base plate.
To do so, place the device towards the top of the base plate,
align the holes on the base plate and the device, and secure with
the supplied 4-40 x 3/16 inch screws.

c. Cut off handle close to wall.

Step 3. — Run Cables
Run signal cables from the proposed PVT input wallplates, control
device location, and the speakers to the WMK 160 location. Cables can
be routed behind the walls, or through a surface raceway (for example,
Wiremold® V700 or 2400 series) directly to the WMK 160.
3A. If running cable behind the walls:
3B. If using a surface raceway:
i. Run all the cables from the various locations to the WMK and through
the access cutout.
i. Slide the WMK cover over the base plate, then identify and
mark the most suitable raceway entrance to the WMK 160.
ii. Run the raceway from the signal source, speaker, and display
locations to the marked raceway entrance at the WMK.
iii. Remove the WMK cover, and remove the desired knockout.
iv. Attach the raceway to the wall. Run cables from the sources
and outputs through the raceway to the WMK.

Step 4. — Cable the Switcher
a. Connect the cables from the PVT wallplates, control device (MediaLink Controller), speakers, and optional accessories
(VoiceLift® and Page Sensor Kit) to the rear ports of the switcher (see gure 7 below).
Refer to the PVS 405D Setup Guide for additional details.
NOTE: If using a device other than a PVS 405D (such as a PVS 305SA IP), refer to the user guide for that device.
b. Run an HDMI cable from the switcher to the output display device through the wall or, where tted, the raceway.
c. Connect the power supply to the switcher and plug it in to the electrical outlet.
NOTE: If the electrical outlet is outside the WMK, pass the IEC power cable out through one of the raceway
knockouts.
