USFM 100 • Installation Guide
IMPORTANT SAFETY INSTRUCTIONS
Read all instructions before starting installation.
When using this accessory, basic precautions should always be followed, including the following:
WARNING: Risk of Personal Injury. Maximum setup load for the USFM 100 (projector arm) is 20 lbs (9.1 kg).
SAVE THESE INSTRUCTIONS
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.
WARNING: Risk of Personal Injury and property damage. Do not exceed specified weight limits of any

The Extron USFM 100 is a mounting kit for suspending ultra short throw projectors from a wall. The USFM 100 base
plate enclosure is capable of mounting a PoleVault® System switcher and its supplied power supply, with sufficient
room remaining for installing additional devices and cable management. It is designed to be used with the UPB 25
universal projector bracket (supplied with the Extron WallVault® system).
The USFM 100 has knockouts on all four sides that allow external raceways or conduits to be attached for cabling
runs where necessary.

enough for signal cables (see figure 2).
d. Remove the base plate and set it aside. Cut out the marked area for cable access.
For drywall with wood studs
i. Drill ¼ inch pilot holes at the marked stud locations.
ii. Align the base plate mounting holes over the pilot holes and lightly secure with 5/16 inch lag screws and
washers.
NOTE: If using toggle screws for assembly, follow the installation method (steps A-D) shown in figure 3.
B. Slide plastic washer down
into pilot hole.
D. Hand screw in pan head bolt
until 1/8 inch gap remains.
C. Cut off plastic handle close
to wall.
A. Grasp plastic handle, collapse
toggle and insert into wall.
Figure 3. Steps for Toggle Assembly Installation
iii. Verify level and position, and fully tighten down all the screws to secure the plate flush to the wall.
For drywall with steel studs
i. Drill a ½ inch (13 mm) hole through the stud at each of the locations (four recommended).
ii. Insert the supplied toggles through the studs and lightly secure the plate using the four supplied
(¼-20 x 2 inch) bolts and washers.
iii. Verify level and position, and fully tighten down all the bolts to secure the plate flush to the wall.
2. Mount the Switcher
a. Place the mounting plate flat on the switcher base with the two small raised tabs on top, and the small
securing tab over 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 using the two 4-40 x ¼ inch pan head screws.
b. Secure the mounting plate (and switcher) to the base plate by aligning the two small tabs on the back of the
mounting plate over the corresponding tabs on the base plate (see figure 4, inset). Slide the mounting plate
(and switcher) down into place. Secure it to the base plate by passing a 6-32x¼ inch screw up through the
securing tab (see figure 4). Tighten down the screw.

3. Run Cables
NOTE: All cable installation should be performed in accordance with local and national building codes, fire and
safety codes, and local and national electrical codes.
Run signal cables from the PoleVault input wallplates, control device location, and the speakers to the USFM 100
location. Cables can be routed behind the walls, through a surface raceway (such as Wiremold 700 or 2400), or
through conduit directly to the USFM 100.

If running cable behind the walls:
Run all the cables from all the locations to the USFM 100 and through the access hole (cut in step 1d).
Proceed to step 4.
If using a surface raceway or conduit:
a. Turn over the left or right cover as needed, and from the inside, cut the most suitable marked raceway or
conduit knockout for the cable to enter the USFM 100. Remove the knockout.
b. Run the raceway or conduit from all locations to the marked entrance and attach to the baseplate.
c. Run the cables through the raceway or conduit to the USFM 100.
4. Cable the Switcher
Connect the cables from the PoleVault wallplates, control device (MediaLink® Controller), speakers, and optional
accessories (VoiceLift, Page Sensor Kit) to the rear ports of the switcher. See the PVS 305SA Setup Guide for
connection details.
NOTE: If using a device other than a PVS 305SA (for example, PVS 204SA Plus), refer to the specific device guide
for details.

5. Attach the Boom Arm, Power Supply, and Projector
a. Hook the boom arm over the top rail on the base plate so that the tab on the arm (see figure 6, inset) is
against the rail. Secure the arm at the bottom with the two supplied (10-32 x 3/8 inch) pan head screws and
washers, and at the top with the single ¼-28 x ¾ inch screw.

b. Secure the power supply within the support end of the boom arm. To do this, pass the tie wraps through the
holes on one side of the arm and then around the power supply (see figure 7). Tighten the tie wraps. The
cables should then be easily and safely routed to the electrical outlet and to the switcher.

Figure 7. Secure the Power Supply inside the Boom Arm
c. Extend the boom arm to the appropriate projector throw distance and secure in the applicable slots with the
four supplied (¼-20 x ½ inch) screws and washers.
NOTE: Do not overtighten the screws.
d. Loosen the set screw (located in the lower hole on the boom arm end), and screw the threaded pipe up into
the end of the arm. A minimum of three turns is needed to safely secure the pipe in place. Lock it in place by
tightening down the set screw.
NOTE: The upper hole on the boom arm end is for attaching an optional seismic/support wire.
e. Run the VGA and composite video cables from the switcher to the projector through the boom arm so
that they exit down the projector mounting pipe.
NOTE: Provide sufficient cable slack within the boom arm to allow for future arm length adjustment.
f. Referring to the UPB 25 User Manual, screw the UPB 25 upper mounting plate onto the threaded pipe and
attach the projector to the UPB 25 projector bracket.
g. Attach the projector bracket (with projector installed) onto the UPB 25 mounting plate and secure.
h. Connect the output cables from the switcher, any MLC control cables, and the power cable to the projector.
CAUTION: Electrical Shock that may result in injury. Do not thread the projector power cable through
the boom arm or mounting pipe. Threading it through the arm or the pipe violates national
electrical regulations.
