NOTICE
• Do not install the clock outdoors.
Damage to the clock if placed outdoors
voids the warranty.
• Do not hang objects from the clock or clock
mounting parts. The clocks are not designed
to support the weight of other objects.
• The clock face and housing may be cleaned
with a damp cloth or disinfectant. Test
other cleaning products on a small part of
the clock housing before attempting to use
on the rest of the clock. Avoid bleach and
chemicals known to dissolve plastics.
VERY IMPORTANT:
KNOW YOUR COMMUNICATION PROTOCOL
The Valcom V-D110XXB Digital clocks are designed to support various 3-wire (sync-wire) communication
protocols. To run each protocol properly, the clock requires the correct wiring format. It is very important
that you only follow the wiring instructions appropriate to your clock’s communication protocol. Using the
wrong wiring format may damage the clock.
WARNING
FIRE HAZARD
• Always follow your national and regional
electrical codes or ordinances.
• The AC power circuit for the clock must
be attached to a circuit breaker that can
be reset by the user.
PHYSICAL INJURY HAZARD
• If you are standing on an object while
installing your clock, make sure that the
object can support your weight, and will not
sway or move as you stand on it.
• Take precautions to avoid injury by potential
safety hazards near the point of installation
including (but not limited to) heavy
machinery, sharp objects, hot surfaces, or
exposed cables carrying an electric current.
• Follow all mounting instructions exactly as
stated in this manual. Failure to do so may
result in the device falling off the point of
installation.
• Packaging materials and mounting items
include plastic bags and small pieces, which
pose a suffocation hazard to young children.
DANGER
SHOCK HAZARD
• Keep the electricity to this device turned
OFF until the clock installation
is complete.
• Do not expose the clock movement to
water, or install the clock in a location
where it may be exposed to water.

PLEASE NOTE: A user will also have to provide a Phillips-head screwdriver, a small flat-blade screwdriver, a single gang box, any equipment needed to install
the gang box, and any additional wiring needed to extend the signal, power, or ground cables. You may also need a 1/4 inch drill, 4 #8x1.5 self-tapping
screws, and 4 wall anchors for those screws if you decide not to attach the clock directly to the gang box.
If any of the items listed in the wiring kit are missing, you may contact Valcom and order a
replacement kit.

3) Attach the communication and power wires from
your kit to the communication and power wires
in the gang box. See the sections of this manual
labeled “Communication Wiring Information”for
additional details, depending on your system.
Wall Mount Installation
1) If you are installing a new gang box in the wall,
leave at least 4 inches between the top of the gang
box and ceiling. Confirm that the bottom of the
gang box is level with the floor.
If you are using an existing gang box, the top of the
gang box must be a minimum of three inches away
from the ceiling.
4) If you do not wish to attach the housing to the
gang box, proceed to step 5A. Otherwise, go to
step 6.
Ceiling
4” Minimum
2) Run power and communication wiring to the
gang box. See the sections of this manual labeled
“Inputs - System Side” for additional details,
depending on your system.
CHECK YOUR WIRING
The voltage between the white and black wires
should measure 105-126 volts AC in the 110
volt model, or Yellow & orange wires for 21.5-
26.5 volts DC in the 24 volt model.
If you are using the 24 volt model, make sure
that the wiring leading to the clock is from a
Valcom power supply or V-VCU.

5D) Use the keyholes in the back of the housing to
hang the clock onto the screws.
5A) If you do not wish to attach the housing to a
gang box, place the mounting piece on the wall.
Leave at least 4 inches between the top rear edge
of the housing and ceiling. Confirm that the bottom
of the mounting piece is level with the floor.
5B) Identify the keyholes towards the top of the
back of the clock housing. Use a pencil to trace the
top of each keyhole onto the wall, then use the
1/4 inch drill bit to drill holes at the locations of the
two marks.
5C) Insert the wall anchors into the two holes, then
place a #8 self-tapping screw into each wall anchor,
leaving at least a 1/8” gap between the top of the
screw and the wall.

1) Install the double gang box in the wall or ceiling.
If you are installing the gang box in the wall, leave
at least eleven inches between the top of the
gang box and the ceiling. If you are installing the
gang box in the ceiling, leave at least eleven inches
between the gang box and the wall. The box should
be installed level and plumb with the wall
and ceiling.

pole by unscrewing the two screws. Set the screws
and pole aside for later.
4) Attach the mounting plate to the gang box using
only two of the four long, silver #6-32x1 screws.
With the mounting plate as a guide, use the pencil
to trace the locations of the four larger holes at the
outer corners.

7) Remove the mounting plate and drill the four
holes that were just traced. Insert the four wall
anchors into the holes.
9) Thread any wiring through the mounting plate,
and attach a grounding wire to the mounting plate
using one of the larger centered holes and the
#10-32x3/8 screw.
8) Reattach the mounting plate, this time using all
four long, silver #6-32x1 screws, then insert the
four #8 screws through the mounting plate and into
the anchors.
10) Use a screwdriver to remove one of the end caps.
The selected end cap should match the position of
the orientation of the clock on the mounting pole;
for example, if you wish to attach the clock to the
pole in a ceiling-mount configuration, then the top
end cap should be removed. The end cap and screw
that was used to secure it will not be needed again
during this installation.
