HARMONIC LOCATOR PROBE: LINE TRACING AND TAP DETECTION
76
When doing a counter surveillance investigation, it is important to analyze all of the wiring in
the environment to ensure that building wiring is not being utilized to transport audio or video
information. This wiring may include but is not limited to telephone wiring, LAN wiring, security
system or access control wiring, intercom speaker wiring, heating and cooling wiring, etc… The
HLP is an ideal tool to work with the TALAN to track miscellaneous wiring and/or identify the
location of a semiconductor device on the wire.
WARNING: Care should be taken when tracing wires to ensure that the Locator Probe
never comes in contact with high voltage wiring.

Figure 1: Front Panel Indicators
Please refer to Figure 1 for the following function descriptions. NOTE: The indicators
are shown as they would be seen in a normal operating condition.
1. The Green LEDs are used to show the relative Received Signal Strength Indication (RSSI) of
the 225kHz injected onto the wire to be traced.
2. The Red LEDs are used to show the relative RSSI of 450kHz. This frequency indicates the
presence of a semiconductor. The injected 225kHz from the TALAN is sent into the wire and
the generated harmonic is being re-radiated.
3. The LOW BATTERY indicator is lit when the 9V battery gets down to 5.8V.
