FOX 2G Tx/Rx AV • Installation and Setup 2-13
Alarm
The alarm pins, labeled 1 and 2, (see figure at right)
on the rear panel of the FOX 2G Tx/Rx AV act
as a short when activated. They do not produce
any discrete on/off voltage signals but, instead,
act as an internal relay that will either connect or
disconnect an external alarm circuit.
For the FOX 2G Tx AV, the alarm state is activated
when link 2 is absent. For the FOX 2G Rx AV, the
alarm state is activated when link 1 is absent.
When power is lost, both the alarm state is
activated for both units.
N The length of the exposed wires in the
stripping process is critical. The ideal
length is 3/16” (5 mm). Any longer and
the exposed wires may touch, causing a
short circuit between them. Any shorter and the wires
can be easily pulled out even if tightly fastened by the
captive screws.
C Do not tin the wires. Tinned wire does not hold its
shape and can become loose over time.
