PR25A
Conductor Tagger & Analyzer
Model PR25A Conductor Tagger and Analyzer is a multifunction test set that
enables fast, accurate tagging of working and non-working lines, while
eliminating the risk of disturbance to the customer. A patented subscriber
sentinel is used to guard against
interruptions or delays of customer calls. Talk battery and alerting features
are provided to obtain and maintain a communications link between points along a
cable.
Automatic Operation
In the automatic mode, the PR25A prevents tones from being introduced to a
working line. If the tone is already induced in a pair while tagging, and the
party on the line lifts the receiver, the PR25A stops the tone before the party
can hear it. If the tone is already induced on a pair, and the party on the line
is called, the unit reacts to the
central office ringing generator and immediately stops the tone.
Visual Monitoring
Cable pairs can be monitored at all times during the pair identification
procedure. A monitoring position is used for visual monitoring without sending
tone. A craftsman can visually check the pair status from the meter on section
throws or cutovers where pairs have been previously identified and it?s only
necessary to determine whether a
line is in use prior to cutting or swinging.
Three Tone Levels
Three tone levels (Low, Medium, High) allows the craftsman to tailor the tone
output to his specific requirement. For example, normal tagging should be
performed with the PR25A sending in the ?Med? tone level position. In short
cables, or where the tone may spread and become hard to identify, the tone
should be sent in the ?Low? position. The ?High? tone level should be used
for extremely noisy and/or long cables.

3 Tone Levels
Ohmmeter & Capacitance Check
Visual Monitoring
577.5 or 500 Hz Interrupted Tone
Automatic Non-Interfering Tone
Adjustable Interruption Rate
Adjustable Interruption Rate
The PR25A interrupted tone is 577.5 Hz (units can be ordered with 500 Hz tone).
The rate of interruption is adjustable, allowing
more than one unit to operate simultaneously in the same cable.
Ohmmeter
The built-in Ohmmeter enables balance testing, subscriber instrument
identification, and checking for rounds and shorts on vacant
pairs.
Standard Equipment
The PR25A comes standard with 577.5 Hz tone, three 9 volt batteries, a
heavy-duty leather carrying case and cords (100B Ground
Cord, 200B Line Cord and 300B Test Tone Cord). A dual purpose carrying strap
also allows the unit to be suspended at eye level
for convenience.
