VERY IMPORTANT:
KNOW YOUR COMMUNICATION PROTOCOL
This master clock is designed to support multiple communication protocols. To run any clock system
properly, the master clock requires the correct wiring format. It is very important that you only follow the
wiring instructions appropriate to your system’s communication protocol. For example, you should not
try to set up an RS485 system by following instructions for a Sync-Wire system. Failure to use the correct
wiring and protocols for your system may damage the hardware.
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.

Identify an appropriate location to install the master clock.
The location should be accessible to the installer, and should be easily able to access its time base. This
means that:
1) This master clock can receive NTP time from any NTP server over a Local Area Network (LAN) as a
standard feature. If NTP is being used as the master clock time source, then the master clock must be
installed in a place that allows it to connect to a network router/switch with CAT5 or CAT6 network cables.
2) The master clock may receive GPS time if it was ordered with an optional GPS receiver module. In this
case the master clock will include a built in GPS receiver module, a GPS cable, and a GPS dome antenna.
The GPS antenna must be installed on the facility’s roof. The master clock should be installed so that the
GPS cable can reach between master clock and the GPS antenna.
3) If the application requires this master clock to receive time data from a third-party master clock, then
this master clock should be installed close enough to the third-party clock that the user can run data wires
between both clocks. Research your communication protocol and provide an appropriate wire gauge and
length to connect both master clocks.
If the master clock is being used to operate a wireless clock system, then there are
additional requirements:
1) The master clock transmitter or Remote Antenna must be placed in a location where the signal is not
interfered with or blocked. Be aware of large structures made of stone, concrete, bricks, or sheet metal
as these materials will block a wireless signal. The installer should also be aware of other objects that may
cause interference to the transmission including, but not limited to, large tanks of salt water, old microwave
ovens, and large industrial machines.
2) The master clock transmitter or remote antenna must be within range of at least one wireless secondary
clock or wireless repeater. If all of the secondary clocks are positioned beyond the range of the master
clock’s transmitter, then the master clock must be connected to the local area network, and a network
repeater must be installed. The maximum transmission distance of the master clock transmitter in an
unobstructed, open space is 3300 feet (1000 meters). Obstructions will reduce this distance, particularly
obstructions made of the materials mentioned in the previous paragraph.

A mounting base and pole must be purchased in order to attach the
antenna to a roof. A dedicated base and pole may be ordered from the
master clock supplier by requesting part number M-GPS-MTG-KIT-1. If the
installer wishes to purchase their own parts, the pole should be capable of
attaching securely to the base and the antenna, which requires either a
1”-14” thread or a 3/4” pipe thread. The pole and base must also each
have a hollow space large enough to allow the GPS cable to pass through
both and attach to the antenna.
If the mounting base and pole are made of metal, then the user must also provide a grounding cable
for the pole. The grounding cable should be 8AWG (8.4mm²) or thicker.
If an optional surge protector is included with the master clock, then the user must provide a second
grounding cable. This cable must also be 8AWG or thicker. Failure to install this grounding cable will
prevent the surge protector from functioning correctly.
Master clocks with the optional GPS Receiver module installed will include a GPS antenna and GPS cable.
The standard cable provided is 75ft (22.9m). A dedicated, longer cable can be ordered through the master
clock supplier by requesting the following part numbers:
E-ANT-CBL-150F-1 150ft (45.7m)
E-ANT-CBL-300F-1 300ft (91.4m)
Please note that Valcom can also provide solutions for projects where a GPS cable longer than 300 feet
(91.4 meters) is required. For more information, please contact your dealer.Using a GPS cable other than
the one provided by your dealer might result in an unreliable time signal. For this reason, using a different
GPS cable than the one provided is strongly discouraged and will void the master clock warranty and support.

Connecting the GPS cable to the master clock is easy: screw that end of the cable into the dedicated port
on your master clock.
Continue by connecting the GPS Antenna to a roof. When installing the GPS antenna, pick a location
where the antenna has a clear line-of-sight to as much of the sky as possible, such as on top of the roof.
Avoid locations that are blocked by trees, tall buildings, metal exhaust vents, large rock formations, and
canyon walls. Do not mount the device inside, on, or immediately outside of a window, as these locations
do not promote reliable signal acquisition.
1) Thread the GPS cable through the mounting
bracket and pole.
2) Screw the end of the GPS cable to the connector
on the GPS antenna. The assembly should now
look like the picture on the right.
3) Insert one end of the pole into the mounting
bracket. While holding the base stationary,
twist the pole counter clockwise until it is firmly
screwed into the base.
4) Insert the other end of the pole into the bottom
of the antenna. While holding the pole stationary,
twist the antenna counter clockwise until it is
firmly screwed onto the pole.
5) If you are using a metal pole, attach a grounding
wire to the pole.
6) Attach the completed assembly to the roof.
7) Within 30 minutes, the antenna should acquire a
GPS signal.
Installing a Master Clock - GPS Antenna (Optional)
If your master clock is set to receive GPS time data
as its primary time input, a loss of GPS time data
will cause a red blinking circle to appear above and
to the left of the third digit on the LED time display.
The circle will blink on and off until the signal is regained, or until a different primary input is set (such as
an NTP server). After completing the installation, make sure that this LED is not blinking.

Installing a Master Clock - GPS Antenna with Surge Protector (Optional)
Customers are offered the opportunity to purchase a surge protector, which is designed to defend the
master clock from a lightening strike to the GPS antenna. The means of connecting the cable to the master
clock is identical to a normal installation, but the procedure for connecting the antenna to the cable and
mount changes:
1) Notice that the surge protector has a tag which
reads COAXIAL SURGE PROTECTOR in the middle,
and GROUND at the bottom.
2) Attach the antenna connector to the PROTECTOR
side of the surge protector.
3) Thread the GPS cable through the mounting
bracket and pole.
4) Screw the end of the GPS cable onto the connector
on the COAXIAL side of the surge protector. The
assembly should now look like the picture on the right.
5) Use a screwdriver to loosen the GROUND screw.
Wrap the exposed end of an 8AWG grounding cable
around the shaft of the screw, then tighten the screw
again. Make sure that the grounding wire runs from
the Surge Protector to the building’s grounding system.
6) Attach the pole to the mounting base. Refer to
step 3 on the previous page.
7) Insert the pole into the brass cap on the COAXIAL
side of the surge protector. While holding the cap
stationary, twist the pole clockwise until it is firmly
screwed into the cap.
8) If you are using a metal pole, attach a grounding
wire to the pole. The grounding wire should be
12AWG or thicker.
9) Attach the completed assembly to the roof. Use
a method that will allow the pole to remain upright
during severe weather conditions.
10) Attach the other end of the GPS cable to the connector on the master clock if you have not done so
already. Refer to the previous page for a diagram.
11) Within 30 minutes, the antenna should acquire a GPS signal.
