1.2. A key variable is whether the HotWire is connected using the Single Wire or Double Wire Method These methods exhibit very different operating characteristics and performance varies greatly In general the Single Wire Method works best to trace a hidden wire through a wall or ceiling and the Double Wire Method works best to identify a wire at the end opposite the HotWire Fox transmitter However this is not a rule to be followed and it often benefits the user to try both methods if possible to find out which works better in the given situation When the Single Wire Method is used so much crosstalk can occur that tracing the wire is difficult because it seems to be everywhere The settings of the Output Level Control on the HotWire Fox and the Sensitivity control on the HotWire Hound can have significant effect on the ability to trace the wire When the Double Wire Method is used the type of wire being traced has a significant effect on the length of wire that can be traced In general small diameter wires are harder to trace than large diameter wires Wires in which the conductors are twisted around each other are harder to trace than wires with parallel conductors For example Romex electrical wire a large wire with parallel conductors is easier to trace than LAN cable a small wire with twisted conductors Page 9 The HotWire Hound senses RF current flowing in a conductor or the Electromagnetic waves in free space In our

6. peak in the signal The most accurate method for locating a wire is by making it null the RF field and then finding this null with the HotWire Hound The HotWire Hound can also sense a peak This is a useful tracing method but not as accurate as the null method Given a choice it is generally best to try to use the null method Page 20 The Null Method The concept of the null is illustrated in the following drawing STRONG ia SIGNAL gt Dl a KK NULL where Hound crosses wire with tracer When the HotWire Hound is passed perpendicularly over the wire with the HotWire Foxs tracer signal a strong signal will be picked up on either side of the target wire and a null dead spot will appear right over the wire The null locates the wire within a few inches While it is possible to take special steps to promote the formation of a null it is generally easiest to just connect the HotWire Fox to the target circuit and see if it nulls by itself For example connect the HotWire Fox to a wall outlet the polarity is not important trace the wire through the wall by finding the null and locate the target circuit breaker by finding the null over the breaker The sound from the HotWire Hound s speaker the brightness of it s LED indicator will show the location of the null The following photos ill

18. e certain characteristics that can be perplexing to an inexperienced user While the RF signal provides the HotWire with the ability to trace AC power wires that are live a disadvantage to using the RF signal is its increased tendency to produce crosstalk in adjacent wires and conductors Crosstalk is the bleeding of the tracer signal from the target wire onto adjacent wires and electrical conductors Because the signal is a radio signal its wants to radiate out of the target wire into the space around it in the same way that a radio signal radiates off of an antenna Consequently it s easy for the RF signal to crosstalk from the target wire to adjacent wires and conductors The HotWire works best when the target wire is in the clear that is not bundled with other wires or run adjacent to metal pipes or other metal structures If the RF signal is applied to a wire that goes through a conduit with numerous other wires the signal can crosstalk onto the other wires making identification of the target wire difficult because all of the wires will have some RF signal on them If the target wire is in a metal conduit the RF signal can crosstalk onto the conduit itself If this occurs the HotWire Hound will trace the path of the conduit not the wire inside This is OK if the wire and the conduit go to the same place But in some instances the target wire make take a different path if the conduit has junction boxes

32. tes Audio Frequency AF signals which can be sensed with the Triplett Hound Hound 2 Hound 3 or Hound Jr In some cases tracing a wire using the AF signal is advantageous The HotWire Fox also includes a very useful feature called TrueTrace In situations where it can be used it provides positive identification of the wire being traced This is especially useful in instances where crosstalk makes identifying the wire being traced called the target wire difficult The 5 RF signal can be sensed through most building materials wood plaster drywall concrete brick etc and can often be sensed through metal conduit because the conduit is often poorly grounded as far as RF is concerned The HotWire can even trace shallowly buried underground wires like those commonly used for Invisible Fences cable television telephone or low voltage landscape light ing The HotWire also includes many other useful features that make it a valuable test tool for many wire tracing applications Page 3 3 Warnings and Cautions The HotWire is designed for use on 120VAC and 220VAC circuits It is intended to be used on fused circuits that are not considered High Energy This generally means that the circuits are appropriately fused to prevent explosive follow on currents that can develop in response to an accidental arc This usually means that the circuit is fused at 40A or less Never connect the HotWir

34. ustrate the process Page 21 HotWire Fox connected to wall outlet Tracing wire in wall Identifying breaker by locating the null Page 22 Helpful Hints It is usually best to start with the RF Level control all the way up on the HotWire Fox adjusting the Sen sitivity on the HotWire Hound so the tracer signal produces a comfortable loudness If it is found that the Sensitivity of the HotWire Hound is turned almost all the way down it may be hard to detect the peak or null of the target wire In this case reduce the RF Level setting on the HotWire Fox and increase the Sen sitivity setting on the HotWire Hound Doing so can improve the ability to find a null over the target wire The HotWire Hound may null over several breakers in the panel Experimentally turn the breaker off If the null effect disappears and tracer signal drops dramatically in level its likely that the correct breaker has been found For positive indication remove the battery from the HotWire Fox before connecting it to the target wires The voltage on the wires will power the HotWire Fox unit If the breaker is experimentally turned off the HotWire Fox looses its power and tracer signal is completely gone For more accurate breaker identification use a Triplett Breaker Sniff It While tracing along the length of the target wire it may be found that at some places the signal nulls and at other places it peaks This normal behavior and is affected
