8.1.4: TONE: Wire Tracing, Identification, & Open Faults
The uses of the FOX Tone mode can usually be divided into
three categories . . . tracing, identification, and locating open
faults.
8.1.4.1: General Wire Tracing Information:
The FOX and HOUND 3 will not trace “live” AC or DC power
wires.
The only type of “live” circuit that the FOX and HOUND 3 will
trace is a telephone circuit.
The FOX’s tracer tone will not penetrate electrically conduc-
tive materials . . . like any kind of metal or wet earth. This
means that the HOUND 3 cannot pickup the tone if the target
wire is in a metal conduit or is underground. The HOUND 3
will pickup the tone at locations where the target wire emerges
from the conduit or the earth.
The FOX’s tracer tone will penetrate wood frame walls and
ceilings, and plaster and drywall. Under good conditions, a
HOUND 3 can pickup the tone from a foot or more away
from the target wire.
The FOX’s tracer tone will pass through any electrical cir-
cuitry connected to the target wire(s). Hence, to identify a
specific wire, it will be necessary to disconnect all loads and
circuitry from the wire. This includes switches, capacitors,
resistors, coils, transformers, lights, motors, etc.
