The
DESCRIPTION:
The
HOUND 2
(PN 3236) is a small, hand-held In-
ductive Amplifier (also called a “Probe”) that, when
used in conjunction with the
Triplett
FOX
or
LAN
FOX
, aids in locating, tracing, and identifying wires,
cables, and other conductors. Often, wires can be
identified without piercing their insulation, and their
location can be determined behind intervening non-
conductive surfaces, such as plastic, wood, or dry-
wall. The
HOUND 2
, with its convenient Volume
Control and LED signal indicator, is useful for wire
tracing in numerous applications, and has been
used in the telephone, electrical, security, sound
reinforcement, automotive, and boating industries,
to name a few.

1)
Contains a hi-gain, hi-impedance amplifier
2)
Has a rugged, moisture resistant, mylar
cone speaker
3)
Volume / Sensitivity control
4)
LED signal indicator
5)
Powered by a standard 9V battery
SPECIFICATIONS:
Battery:
9 volt alkaline, NEDA 1604A, such
as Eveready 522
Size:
Diameter: 1.5" (body), 1.9" (at speaker)
Length: 8.25" (including probe tip)

Less than 8 ounces with battery
BATTERY REPLACEMENT:
Unscrew speaker grill cap. Remove speaker, be-
ing careful not to damage wire connecting to
speaker. Remove foam pad. Replace the battery.
Reassemble.
OPERATING INSTRUCTIONS:
Two different basic tracing methods are commonly
used.
Figure 1
illustrates the “LINE/GROUND” con-
nection, and
Figure 2
illustrates the “LINE/LINE”
connection.
FOX LINE/GROUND Connection:
The LINE/GROUND connection produces the stron-
gest tracing signal, but also creates “crosstalk” of
the signal into other wires in the cable. If the user
is trying to identify a cable, and not an individual
conductor in the cable, the LINE/GROUND method
usually produces the best results. This method has
been used to trace electrical wires (like Romex),
speaker wires, intercom wires, thermostat wires,
alarm wires, cable television wires, etc. through
drywall, wood flooring, and carpeting.
A “good” earth ground is usually not required. In
fact, a large metal object like an office desk, a file
cabinet, or a metal plate on the floor, can be used.
On vehicles, the metal chassis of the vehicle can
be used as the ground. A metal hulled boat can
use the hull as a ground, and a wood or fiberglass
hulled boat can use the surrounding water as a
ground (make connection to a metal fitting in con-
tact with the water or drop a wire into the water).
The ground connection is only required at the
FOX
end of the cable or wire, however, a ground con-
nection at the far end is handy for positive identi-
fication of the target wire (read following text on
tracing).
To setup the LINE/GROUND connection, clip one
alligator clip (either color) of the
Triplett
FOX
to
the “ground”, and the other alligator clip to the
wire being traced (see Figure 1).
FOX LINE/LINE Connection:
The LINE/LINE connection is useful for identifying
a pair of wires in a multi-wire cable, or for identi-
fying a pair of wires in a bundle of wires. When
wires are “paired” in a cable, they are often twisted
together in a manner that reduces crosstalk of any
signal on the wires into adjacent wire pairs. Tele-
phone cables are constructed in this manner, so a
LINE/LINE connection is often used to trace tele-
phone cables (see Figure 2). The
FOX
’s modular
plug applies a LINE/LINE connection when plugged
into its mating modular jack (connected to a tele-
phone line).
Initial Setup and Testing:
Whether the LINE/GROUND or LINE/LINE connec-
tion is used at the
FOX
, the use of the
HOUND 2
for tracing the signal is the same. In general, the
HOUND 2
is used by bringing it into proximity with
the wire/cable that is being traced, listening for the
TONE signal from the
FOX
, and moving the
HOUND
2
in such a manner as to increase the loudness of
the TONE signal from the
HOUND 2
’s speaker.......
i.e. searching for the loudest TONE signal. The
HOUND 2
’s Volume Control is adjusted to a com-
fortable level. Usually, it is set to maximum when
the tracing wires through walls and ceilings, and
is set to a lower setting when in close proximity to
the signal carrying wires. The
HOUND 2
’s LED
glows brighter when the sounder from the speaker
is louder. In situations where there is a lot of acous-
tic noise, observing the brightness of the LED may
prove more useful than attempting to hear the sig-
nal from the speaker.
To begin using the
HOUND 2
, turn the volume all
the way up by rotating the VOLUME thumbwheel
towards the speaker. Depress the Power Button
on the
HOUND 2
. It is normal to hear a humming
or buzzing noise coming from the
HOUND 2
’s
speaker when it is in an area with fluorescent lights,
neon signs, transformers, etc. In fact, an easy test
to verify the
HOUND 2
is working is to move it
toward an operating fluorescent light and note that
the buzzing sound gets louder, and the brightness
of the LED increases. When used out-of-doors,
away from power wires, the
HOUND 2
may make
only a slight hissing noise.
Before attempting to trace a wire/cable, set the
FOX
to the TONE mode, and depressing the
HOUND 2
’s
Power Button, bring the
HOUND 2
’s probe near
the
FOX
’s alligator clips. The TONE should be heard
from the
HOUND 2
’s speaker. If the TONE is not
heard, check the batteries of both the
FOX
and the
HOUND 2
.
After verifying that the
FOX
is generating a TONE,
connect the
FOX
to the target wire/cable in the
desired fashion. Once again, test the
FOX
’s output
signal by depressing the
HOUND 2
’s Power But-
ton and bringing it’s probe near the
FOX
’s alligator
clips (this is called “probing” the wire/cable). The
TONE should be heard from the
HOUND 2
’s
speaker. If the TONE is not heard, the wire/cable
may be shorted. The
HOUND 2
cannot trace a
shorted wire.
If the LINE/GROUND connection is being used, the
alligator clip connected to the ground should have
very little signal on it when probed by the
HOUND
2
. The other clip attached to the wire/cable should
have a strong signal on it.
