Power Considerations
In standard configuration, each locker room clock display requires a standard (NEMA 5-
15R) AC power receptacle providing 120 VAC at 60 Hz. We recommend providing a
disconnect switch to kill power to this receptacle when the clock is not in use. Here we
will assume that the receptacle is available, or that power is being supplied directly via a
concealed wiring configuration. A Model LX7406 locker room clock draws a maximum of
0.3 amps.
Junction Boxes and Data Cable
In the unusual situation that your locker room clock includes a ScoreLink wireless
communication system, your work is done here. Skip to the next section.
A standard locker room clock usually acquires data as it is daisy-chained from the main
scoreboard display. However, some situations may require one or more junction boxes,
which you should permanently mount to
provide a stable point of termination for the
data cables. The idea is to connect the clock
to a junction box via a patch cable. So the
junction box will need to be mounted near the
clock (usually no more than 10 feet apart). In
many gyms, junction boxes are concealed
inside a larger floor box. They can be flush
mounted on a wall, externally mounted on
bleachers, or positioned anywhere else that
is convenient. Choose a location that is
protected so that the junction boxes and
cables are not likely to be stepped on, tripped
over, or have liquid (or anything else) spilled on them.
It is also important to label your junction boxes. The connectors used for scoreboard
data look very much like the type used in some audio systems. Plugging audio devices
into a scoreboard data line can damage the scoreboard system.
Each junction box ships with a length of cable
soldered to the stereo socket and tucked
inside the box. There should be no need to
solder cable to this socket during the
installation. Instead, splice the wires from the
data cable to the pigtail inside the junction
box, matching colors. The wires in the pigtail
are 22 AWG, and the cable should use the
same size conductors. The installer must
