Important Safety Instructions

VERY IMPORTANT:

KNOW YOUR COMMUNICATION PROTOCOL

The Valcom Wired clock is designed to support the 2-Wire Digital Communication Protocol as well as
3-wire (sync-wire) communication protocols. To run either system 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. For example: if your system includes converter boxes which are only used for the
2-wire system, then you should only follow the instructions that relate to the 2-wire digital communication
protocol wiring.

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.

Frequently Asked Questions

How do I know if the clock is receiving data?

Perform Diagnostic 2. See the section labeled “Diagnostic Test #2 - Comprehensive Test”. The result should
correspond to your system’s synchronization settings.

Example 1: The two-wire digital system should result in the clock recieving communication within the
last hour.

Example 2: Once-a-day sync systems may return a result of 11 hours or more, depending on when you
conduct the test. In this case, the test should be conducted less than nine hours after the synchronization
signal is sent.

What size utility/gang box is needed?

A standard single gang box is required for wall mounting a clock. However, if you are installing a double
mount or flag-mount clock, then a standard double gang box is required.

Do I need to power up all the clocks at the same time?

No. Clocks that are added to the system after power up will begin running and wait for correction signals
from the master clock. Sync-wire systems may take up to 24 hours to receive a correction signal.

Do I have to reset the clock if it suffers a power outage?

No. The clock will resume operation after the power outage, and will adjust to the correct time as soon as
it receives a signal from the master clock.

What happens if I power the Valcom Wired Clock before connecting the master clock?

The clock will begin to run, but the time displayed will be incorrect. As soon as signal wires from the
master clock are connected and a synchronization signal is sent, the Valcom Wired Clock will correct itself
to display the correct time.

Can I manually set the time on the clock?

No. Furthermore, attempting to open the front crystal or moving the hands manually will damage the clock
and void your warranty.

Questions about Protocols

How do I set up the Valcom Wired Clock to accept synchronization protocols from Rauland,
Dukane, and other systems?

If you are receiving the protocol directly from the master clock, your Valcom Wired Clock will automatically
detect the sync-wire protocol being used when it first powers up; no action on your part is required.

If you wish to use Valcom’s 2-wire digital protocol to carry synchronization data from a system that uses
an unsupported protocol, a Valcom Master Clock must be used as an adapter between the two wiring
systems. Consult the wiring guide in your Master Clock manual for more information.

How do I select which protocol I want my Valcom Wired Clock to use?

When you power up the clock, your Valcom Wired Clock will automatically recognize the protocol being
used as soon as it receives data.

Can I change protocols if the system is running?

Yes. There are two ways of doing this:

1) Do nothing. Within three days of being plugged into the new protocol, the Valcom Wired Clock will
automatically notice the change in protocol and correct itself.

2) Reset the clock to manufacturer’s default. Perform Diagnostic #3, then, after Diagnostic #3 is complete,
power cycle the clock.

How do I check to confirm that the Valcom Wired Clock is receiving the correct protocol?

Perform Diagnostic #1

How do I perform diagnostic tests on the clock system?

See the sections on the pages labeled “Diagnostic Test #1 - Protocol Verification”, “Diagnostic Test
#2 - Comprehensive Test”, or “Diagnostic Test #3 - Manufacturing Default”, depending on your needs.

I am adding a new clock into an existing Valcom Wired Clock System. Do I have to set my entire
system back to 12:00?

No. The new Valcom Wired clock will automatically correct itself upon receiving the data signal from the
master clock.

Troubleshooting

The clock is plugged into the power, but it is not running. What should I do?

a) Make sure that the movement’s gearbox pin is removed.

b) Make sure that the ground wire is not touching other wires.

c) Make sure that the transformer is an isolated transformer if using a 24 volt model.

d) Measure the voltage between the power (black) wire and the neutral (white) wire. The voltage between
the white and black wires should measure 105-126 volts AC in the 110 volt model or 21.5-26.5 21.5-26.5
volts DC in the 24 volt model.

*Failure to follow instructions c and d can result in a blown fuse.

The clock is not receiving a communication signal from the master clock. What should I do?

Follow these steps in order:

1) In order to check the last time the clock received communication from the master clock, perform
Diagnostic #2. See the section labeled “Diagnostic Test #2 - Comprehensive Test”

2) Compare the time that the last signal was recieved to the parameters of your protocol. If the amount of
time since the last signal was recieved is more than the amount of time since the clock last recieved time
data, then there is a fault with the system.

3) Check your master clock and confirm that it is sending time data at the correct protocol and at the
correct time. Consult your master clock manual for more information.

4) If your master clock has been properly configured, take the clock off the wall and test it at a location
close to the master clock’s signal output (or the converter box signal output, if a 2-Wire Digital System is
being used). Use the master clock to send time data to the clocks.

If the clock corrects itself, then there was a problem with the wiring to the clock’s original installation
point, and the wiring must be repaired or replaced.

If the clock still fails to correct itself, contact tech support.

I can hear data noise bleeding into the intercom line. What should I do?

Reduce the transmission rate from the master clock to once a minute. Please refer to the master clock
manual for information on how to change the transmission rate.
