The Leviton tone test set is used in low voltage wire applications such as telephone and data, HVAC systems, and security or fire alarm wiring to perform a variety of functions. As a tone generator, a
toner can be connected across a wire pair to transmit either a continuous 1000 Hz tone or an alternating 500/1000 Hz tone; with the use of the Speaker Probe (below), you can quickly and easily trace pairs and locate broken pairs/cables in walls. Multiple circuits can be traced by using two test sets, set to opposite tones.
A tone test set also tests for continuity, checks for shorts or opens, and provides talk battery for a communication line or a dry pair. Also identifies Tip and Ring polarity, and line condition for CLEAR LINE, BUSY LINE, and RINGING LINE.
This unit has several enhanced features: "O" ring seals on the case and test leads for water resistance, and a unit support leash is attached to the case to prevent
straining the test leads when hanging the unit from a 66-block or jack wile tracing the tone. A dual-color,
light-emitting diode (LED) is used for all test indications. Durable, nylon-braided tinsel wire test leads ensure long life and reliability.
Telco-standard, 6A-type alligator clips with piercing pins securely grip 66 clips, screw heads,
screw bodies, and wire wrapped or threaded terminals. A 6-position 2-conductor plug lead is also
provided for connection to modular jacks.
The streamlined Inductive Speaker Prove detects audible frequency tones quickly for accurate tracing
and identification of wires, cables, and metallic circuits. Use with the tone test set above to trace and isolate pairs in virtually any type of wire application, without damage to the insulation.
The Speaker Probe can identify single wires or individual pairs in multiple-pair cables at terminals or
closures; identify station wiring or cables to specific equipment in closets or on distribution frames and
identify drop wires or buried service wires. It can also be used to locate prewiring after wall covering is
installed, and to locate opens in wires.
Designed to get into tight spots with ease, the Speaker Probe comes with a needlepoint tip and a
duckbill tip. The duckbill tip enables insertion into larger cable bundles or cables under tension where slack cannot be obtained. Normally with the built-in speaker, a butt set is not required. In noisy environments, use a butt set as a monitor by attaching it to the probe's strudy connecting tabs. Non-locking slide switch prevents accidentally leaving the unit on and draining the battery.
