Finding the Wire Break
Begin where the twisted pair of wire exits your home (through a window, door, or wall) using
the Receiver.
The two transmitted signals mix over the twisted pair going from the Transmitter to the
boundary loop. As a result you will hear both the low frequency continuous tone and the
higher frequency intermittent tone together.
If both wires are damaged in the twisted pair, the signal from the Receiver will decrease as you
near the break and quit after you have passed the break.
If only a single wire is broken you will hear both tones as you follow the twisted wire away from
the transmitter. At the point where the single wire is broken, only a single tone will be heard.
If you have not located a break(s) in the twisted pair of wires, you will eventually get to the
Boundary Wire connection point.
When you get to the end of the twisted pair at the boundary loop, the signals will separate
again and you will hear one signal as you follow the boundary wire in one direction, and you
will hear the other signal as you follow the boundary wire in the other direction.
Note: If the twisted pair is greater than 100 feet, an intermittent and steady tone will most
likely be combined over the entire Boundary Wire. If this occurs, you will hear a noticeable
reduction in sound volume over the break.
Choose a boundary direction and continue walking along the Boundary Wire. When you come
to a break in the Boundary Wire, there will be either no signal or the signal will cross over from
intermittent to continuous or continuous to intermittent. Once you’ve identified the general
location of the wire break, move the Receiver 2-3 feet from the break. Turn the volume down
on the Receiver until you only hear the sound when you are directly over the wire. Move the
Receiver towards the wire break. When the sound disappears, you have located the break. The
break should be directly below the Receiver.
As you move further from the Transmitter, the Receiver volume will gradually decrease. This is
not to be confused with a wire break.
If the twisted pair is greater than 50 feet and there are keep-out areas such as gardens and
pools in your Boundary layout, you may need to locate the break by listening for a reduction in
the sound volume.
If there are multiple breaks, keep repairing as you go around. If the lawn was aerated,
replacing a larger section of wire may be easier than making small section repairs. Go back to
the twisted pair and walk the Boundary Wire in the other direction until the signal disappears
for that break. Replace the wire between the two ends of the Boundary Wire breaks.
