Wireless System Setup
1. Identify an appropriate location to install the master clock or remote antenna. See the pictures on the
next page for examples.
• The master clock transmitter or Remote Antenna must be placed in a location where the signal will not be
blocked or inhibited. Be aware of large structures made of stone, concrete, bricks, or sheet metal (including
metal network cabinets) 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.
• 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.
2. Install the master clock and confirm that it is properly configured and powered on
. DO NOT
INSTALL SECONDARY CLOCKS UNTIL THE MASTER CLOCK IS CONFIGURED AND POWERED.
3. Confirm that the antenna has been correctly installed. For surface-mount master clocks, the antenna
should be installed in the socket on top of the master clock. For rack-mount master clocks, the remote
antenna should be plugged into the socket on the back of the master clock. Refer to the Remote Antenna
installation instructions, step 7, for details and a diagram.
4. Power all secondary battery-powered clocks within the same room as the master clock.
Wait until the
clock recieves time data from the master clock before taking it to its point of installation
. Refer
to the secondary clock manual for detailed steps.
Please be aware:
A master clock equipped with a wireless transmitter will automatically begin to transmit time data every
minute, beginning at the top of the minute.
If a repeater is being directly powered by the facility’s electrical systems, then the repeater will receive time
data and correct within the first 60 seconds, or immediately upon being powered on.
If a wireless secondary clock is being directly powered by the facility’s electrical systems, then the
secondary clock will receive time data and correct within the first 60 seconds, or immediately upon being
powered on.
If a wireless secondary clock is being powered by batteries, then the clock will receive time data and
correct within the first 2 hours (in normal mode) or 4 hours (in economy mode), or immediately upon
being powered on.
If a wireless secondary clock or repeater is not receiving power from the facility’s electrical systems or
batteries, then the clock or repeater will not function at all. Wireless clocks and repeaters ARE NOT
POWERED WIRELESSLY, they only receive time data wirelessly.
If a wireless secondary clock or repeater is powered, but the master clock is not powered, then the wireless
secondary clock or repeater will not receive time data.
