Voice tagger wire tracing system

19 May 2004 Test & Measurement

The Tempo Voice Tagger is a wire tracing system that can be used to identify eight to 16 wires at a time. This is especially useful when working with groups of wires that fan out to various locations. An example is cable TV drops in an apartment building. The Voice Tagger uses human voice numbering to 'tag' the traced wires, making it easy to distinguish them using any standard pair tracing probe.

In the example (pictured) the Voice Tagger is used to identify the drops to six different apartments from a group of coax cables in the entrance room. The cables were not marked when they were pulled through the walls. Voice Tagger leads 1 through 6 are connected to the centre conductors of cables labelled 1 through 6, and the green ground lead is connected to a nearby ground. When touching the cable end in each apartment with a standard tone probe (like the Tempo 200EP or 200FP) the cable number will be heard. In the case shown, Apartment E corresponds to cable 5, and the words '... five, five, five ...' can be heard from the probe speaker. Though it is possible to trace by putting the signal on unterminated shields, the best results are obtained by using the centre conductors.

The Voice Tagger also provides a standard warble tone trace signal 460/920 Hz. The signals are compatible with voice twisted pair, Category 5 or 6 data cable, coaxial cable and non-energised electrical wiring. Powered by one 9 V battery, the 140 mm long device is 70 mm wide and 32 mm high.
