the FOX 2 to the LAN cable. Connect 7 of the LAN wires
together, leaving the open faulted wire as the 8th wire. Con-
nect the 7 wires to one clip of the FOX 2, and connect this
clip to earth ground. Connect the open faulted wire to the
other clip of the FOX 2. Trace along the path of the cable
(which has already been located) with a HOUND or HOUND
2, listening for a sudden drop in the tone level. When this
drop is found, note its position. Continue tracing along the
path of the cable. If the tone level stays low, the point at
which the level dropped is probably the location of the open
fault. If the level comes back up, there was probably an un-
seen obstruction that caused the level to drop. Continue trac-
ing along the cable until the “true” open is found.
Alarm / Security Wires:
Alarm and security wires can be traced like other wires.
The FOX 2’s TrueTrace feature and a Hound, Hound 2, or a
cordless telephone makes testing enclosed magnetic
switches easy. Simply connect the FOX 2’s clips to the tar-
get wire pair at the alarm control panel, and set the FOX 2 to
TRACER TONE. Then, simply open and close the protected
opening, or use a test magnet, to actuate the sensor. With
the Hound, Hound 2, or cordless telephone, listen for the
cadence to change. If it changes, you’ve identified the proper
wire, and verified that the sensor is working.
If there is an EOL resistor on the line, it may be necessary to
remove it for TrueTrace to work. To find out if the EOL needs
to be removed, turn on the FOX 2, set it to TRACER TONE,
and connect it’s clips to the wires. While listening to the
