Important Safety Instructions
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.
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.
H
|
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.
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.

Manual Controls (V-D110XXB Only)
The numbers shown on the left are examples. Going down the list and entering every one
of the examples exactly as shown will cause the clock to malfunction or use incorrect data.
Program your clock setting based off of the instructions in the description on the right.
The settings below only apply to Valcom analog clocks using wired communication protocols such as
2-Wire Digital. The digital clock cannot send these commands to Wireless, IP or Wi-Fi clocks.
Setting 40 - Command Analog Clock to Perform Diagnostic
40-- d
Allows the user to send a command to all analog clocks receiving data from
this digital clock. The available commands are the diagnostic tests listed in the
table below:
01 - Diagnostic 1 -
Protocol Verification
02 - Diagnostic 2 Comprehensive Test
Details on the function of each diagnostic test can be found in the analog
clock manual.
Setting 41 - Diagnostic Results Display Duration
41 - 60
Pressing the top button after Setting 41 will cause the clock to return to the normal time display.
This setting determines how long the results of a diagnostic test will remain
on the face of an analog clock. Due to the nature of the tests, this time period
only applies if values 01 or 02 were selected for Setting 40.
Press the bottom button to scroll from 00 to 99. For example, a value of 98 will
set a display duration of 1 minute and 38 seconds.

Reading the Display
The digital clock is designed to display time in either a 12-hour or 24-hour format. When the display is set
to the 12-hour format, a circular light will appear in the top left corner of the display to indicate PM, or
disappear to indicate AM. When the display is set to the 24 hour format, the full 24-hour time will appear
on the display; no other lights should appear.
Some examples:
5:30 AM (12-hour format)
5:30 PM (12-hour format)
5:30 AM (24-hour format)
5:30 PM (24-hour format)
The factory default setting for all digital clocks is the 12-hour format. If you wish to set the clock to display
time in a 24-hour format, see the section labeled “Jumper Settings”, included earlier in this manual.

Frequently Asked Questions
Can this digital clock be used as a standalone clock?
The Valcom Digital V-D110XXB can be used as a standalone clock, but it will not keep synchronized time
in this configuration. Instead, it will rely on an internal quartz oscillator for keeping the time. The clock will
drift by a few seconds each year while in this mode, and will need to be readjusted manually.
How can I use this digital clock with Rauland, Dukane and other systems?
V-D110XXB clocks can be added directly to several sync wire systems. Refer to the Inputs section of this
manual for instructions on how to connect the clock to each system type.
V-D24XXB-6 clocks can obtain time from these systems through a master clock working as a translator.
Data from the other system would be sent to the master clock, and then the master clock would send the
data to the digital clocks through 2-wire or wireless communication protocols.
What happens to the digital clock if a power failure occurs?
If a power failure occurs, the display will shut off but the clock will continue to keep time with its internal
quartz oscillator. This oscillator will continue to run on a tiny battery backup for about ten years. In this
mode, it may drift from synchronized time by a few seconds for each year that the clock is without power.
Once power is restored to the clock, the display will turn on and display the time on the quartz oscillator. It
will correct this to accurate, synchronized time once a signal from a master clock is received.
What happens to the digital clock if contact with the time data source is lost?
The digital clock will rely on an internal quartz oscillator for keeping the time until time data is received.
The clock will drift by a few seconds each year while in this mode, and will need to be readjusted manually.
The V-D110XXB digital clock is able to act as a master clock. If the communication input is lost to the
V-D110XXB, and the V-D110XXB is acting as a master, then the clock will send synchronization data to any
clocks down the line that are connected. This data will be based off of the V-D110XXB’s quartz oscillator,
so while the clocks will be synchronized to each other, they may not be showing accurate time.
How can I display “BELL” and “FirE” on the clock?
“FirE” and “BELL” are signals sent by the appropriate master clock. Refer to the master clock manual
for instructions.
For 24V clocks, what happens if voltage on the power line drops from 24V to lower voltage?
The clock will still function, and will maintain the same level of brightness. However, the current
consumption will increase proportionally to the decrease in voltage.

Troubleshooting
The clock is not running. What do I do?
1. Measure the input voltage to the clock. The voltage should measure 85-135 volts in the
120VAC model or 240VAC model or 10-28 volts in the 2.5”/24VDC model and 16-28 volt in
the 4.0”/24VDC model.
2. Make sure the ground wire is not touching other wires.
NOTE: If you fail to follow instruction 2 the fuses can be blown.
The clock is not receiving an input signal. What do I do?
1. For V-D110XXB, Make sure that JP6 is in the proper position. Refer to “Adjustable Jumper
Settings“ for
details and diagrams.
2. For V-D24XXB-6, Make sure that the polarity of the communication wire is correct when using
the clock in 2-wire digital communication mode.
3. For V-D110XXB, make sure that the input voltage is zero when not applying a correction
signal. When taking this measurement, you must be sure that the clock is disconnected from
the master clock. Also, measure both AC & DC voltage. (The current consumption needed
is very low, about 3mA, and a leakage current from the master clock can be interpreted as
a continuous reset signal. If you are experiencing such a problem, please install a bypass
mechanical relay).
