Find the Wire Break
For Systems with Twisted
Boundary Wire
• If a single wire in the twisted wire is broken,
you will hear both tones until the locator
reaches the break in the wire. Then you will
hear only a single tone.
• If both of the wires are broken in the twisted
wire, the volume from the locator will
decrease as you approach the break. The
tone will stop after you have passed the
break and the lights will disappear.
1. Begin outside where the twisted boundary
wire exits through a window, door or
wall (
5A
).
2. Place the locator directly over the buried
wire. The locator will pick up the 2
transmitted tones of the buried twisted
boundary wire. As a result you will hear both
the low frequency continuous tone and the
high frequency intermittent tone together.
3. Adjust the volume so that the tones are loud
enough to hear over normal outdoor noise.
4. Walk along the path and swing the
locator from side to side, listening for the
simultaneous tones (
4C
). The light that is
associated with the strongest signal will be lit.
Check the Boundary Wire Loop
• If there is a single break in the boundary loop, the tone will most likely change from one tone to
another (intermittent to continuous or from continuous to intermittent). The lights will also switch from
one colour to the other. Ideally, if the tone disappears, you have located the break directly below
the locator.
• If there are multiple breaks in the boundary loop, the locator tone will decrease and will go silent
at the break, and the lights will turn off.
1. If you do not locate a break in the twisted wire, then you will eventually reach the splice where
the twisted wire meets the boundary wire loop in your yard
(
5A
). You will only hear a single tone
(either intermittent or continuous) from one of the single boundary wires. You will also see only one
colour on the locator (either red or green).
2. Select a direction and walk the boundary wire loop while listening for a change in tone or colour.
Note:
It may be difficult to hear the changes between tones due to the loud volume on the locator.
When you do hear a change in tone, stop and turn the volume down on the locator until you barely
hear the tone when you are directly over the wire. Move the locator towards the area of the wire
break. When the tone disappears, you have located the exact location of the break directly below
the locator.
We recommend repairing the breaks as you go around the entire loop.
Note:
If the lawn was aerated there might be multiple breaks throughout the wire. It may be easier to
replace a long section of wire rather than making several small repairs.
To do this, go back to where
the twisted wire meets the boundary loop and check the boundary wire loop in the opposite direction
this time. Once you find the break in the wire then you can estimate how long of a section of wire you
will need to replace.
Things to Keep In Mind
• As you move further from the transmitter, the locator volume will gradually decrease. This is not to
be confused with a wire break. You may need to increase the locator volume in order to continue
hearing the signal.
• If the twisted wire is greater than 15 m and there are off-limits areas such as gardens and pools
in your boundary layout, you may need to locate the break by listening for a reduction in the
tone volume.
• If the twisted wire is greater than 30 m, the intermittent tone and the continuous tone will most likely
be combined over the entire boundary wire. If this occurs, you will hear a noticeable reduction in
the tones when the locator is over the break, and the colours may not change over the break.
