DESCRIPTION:

The 

FOX

  (PN 3380) is a small, multi-function,

hand-held instrument for testing telephone lines.
In addition, when used in conjunction with an In-
ductive Amplifier, like the 

Triplett HOUND

  or

HOUND 2

, the 

FOX

 can be used for identifying, lo-

cating, or tracing wires inside of or behind sur-
faces that are electrically non-conductive (like dry-
wall).

When used for tracing wires, the 

FOX

 can be used

with non-energized electrical power wiring, alarm
wiring, speaker wiring, coax, cable harnesses, and
numerous other wires and cables. For more com-
plete information, see the 

HOUND

  or 

HOUND 2

Instruction Manuals.

To facilitate testing, the 

FOX

 uses two alligator clips

and a modular plug. These allow the 

FOX

  to be

quickly connected to stripped wires, terminal pan-
els, or a standard RJ-11 modular jack (single line).
Two selector switches set the test function of the

FOX

, while an LED acts as a visual indicator. By

setting the selector switches appropriately, the 

FOX

generates three distinct tracer tones, which, as
previously mentioned, can be used for locating
wires or cables with an inductive amplifier such
as the 

Triplett HOUND

 or 

HOUND 2.

     Current via the LED

4)

  Supplies “Talk Power” to allow communicating

     between handsets (aka: talksets or “buttsets”).

5)

  Provides recharge current for a Nicad battery

OPERATING INSTRUCTIONS:

Checking Line Polarity:

The 

FOX 

indicates proper line polarity by lighting

its LED.  To perform this test, set the 

FOX’s

 Func-

tion Switch to OFF/LINE POLARITY.  Attach either
the alligator clips or the modular plug to the con-
nection to be tested.  The 

FOX’s

 LED will light when

the Red alligator clip is connected to the Ring wire
(negative) and the Green alligator clip is connected
to the Tip wire (positive), or, when the modular
plug is inserted into a properly polarized single line
modular jack.  Although the LED will light on a
BUSY (off-hook) line when performing the test, the
LED will light much more brightly if the line is
CLEAR (on-hook).  The 

FOX

  also indicates line

polarity, when the line is CLEAR, in the TONE Mode.
However, the line polarity LED may or may not light
in the TONE Mode, on a BUSY line.

NOTE:

  LINE POLARITY can only be measured on

lines powered by the Central Office (CO) battery.

Wire Tracing / TONE Generation

The 

FOX 

can generate one of three distinct tones;

LO, HI, or WARBLE.  This feature allows 3 

FOXes

to be used on the same installation site to trace 3
cables at the same time, without creating confu-
sion.  To “send” a tone, set the 

FOX’s

  Function

Switch to TONE, and select LO, HI, or WARBLE

with the other switch. Connect the pair of wires to
be traced to the 

FOX’s

 alligator clips or modular

plug.  The 

FOX

 can be connected to powered (CO

battery) or unpowered phone lines.  The far end of
the cable being traced can be located by using a
handset, when metallic connections are possible,
or with an inductive amplifier such as the 

Triplett

HOUND

  or 

HOUND 2. 

For alternate wire tracing

methods, refer to the 

HOUND

 or 

HOUND 2

 Instruc-

tion Manuals.

Line Powering:

In the TONE Mode, the 

FOX 

can be powered from

CO current.  The 

FOX’s

 internal 9 volt battery is

not needed.  To use this feature, simply connect
the 

FOX’s

 Tip and Ring wires (either clips or modu-

lar), in either polarity, to the powered line on which
the tone is to be sent.  The 

FOX

 will not “seize” or

“capture” the line of most phone systems.

NOTE:

  Although the 

FOX

 does not require a bat-

tery when generating a tone with line power, if a
battery is in the 

FOX

, it will be used as part of the

FOX’s

  power source.  Due to the 

FOX’s

  internal

circuitry, less battery power is used if the 

FOX

 is

connected to the line in Reverse Polarity, i.e. Tip
to Negative, Ring to Positive.  Therefore, for great-
est battery life, connect to a powered line in Re-
verse Polarity.

***WARNING***

The

 FOX

 is designed to work on non-energized (ex-

cept telephone lines) wires or cables.  Attempting
to test energized wires may damage the 

FOX

, cause

user injury, or both.
