Here are some examples of wire coverage:
The above figures assume a rectangular layout and actual
footage may vary.
2. Placing the Wire
For the system to work properly, the wire must make one con-
tinuous loop. The signal is transmitted from one terminal of
the transmitter, through the wire, and back to the other termi-
nal. When placing the wire, keep in mind that you will want at
least a 8- to 12-foot containment field (8 to 12 feet on each
side of the wire). Avoid making passageways too narrow or
your dog may be hesitant to use them (i.e. along the sides of
a house).
3. Using Twisted Wire
Prepare and place twisted wire from the transmitter to the
exterior loop wire. The twisted wire cancels the signal and
allows your dog to cross this area. It can also be used to con-
nect the containment system to internal areas that should be
protected, like gardens, pools, and special landscaping.
To twist the wire, cut two equal lengths and hold them side by
side. Put one end of both wires in a power drill. With a helper
holding the other ends of the wires, turn the drill on and spin
the wires until the twists are 2 to 3 inches apart. The tighter
the twisting of the wire, the better the signal cancellation. The
wire can also be twisted manually.
4. Rounding Corners
Use gradual turns at the corners with a minimum of 2.5-foot
radius. This will produce a more consistent containment field
and avoid confusing your dog in these areas.
5. Crossing Driveways, Sidewalks, and Water Features
When crossing an asphalt driveway, make a 1/2-inch deep
cut across the driveway using a circular saw and masonry
blade. Place the wire in the crack and seal with asphalt
sealant. On driveways and sidewalks, if an expansion joint is
available, simply place the wire in the joint and seal with an
outdoor caulk. When crossing gravel, bury the wire at least 3
inches deep. Use a piece of garden hose or plastic PVC pip-
ing to protect the wire. In water, anchor the wire with large
rocks. Protect the wire with a piece of garden hose or plastic
PVC piping. The wire does not have to be buried, but to min-
imize the potential for wire damage, it is advisable to bury it at
least one inch underground.
E. Placing the Boundary Wire
1. Listed below are important tips about placement and burial
of the boundary wire:
• Do NOT bury the loop within 10 feet parallel to electrical,
telephone, cable TV, or other buried wire in the yard.
• Do NOT bury one section of wire within 10 feet of another
section or the signal may cancel.
• Do NOT bury your wire within 10 feet of a neighboring con-
tainment system's boundary wire.
2. Position the Wire in the Yard
The above recommendations may cause you to modify your
layout, but it will be time well spent. When your layout is final-
ized, place the wire around your property according to your
diagram. The wire loop should begin and end at a perimeter
location closest to the location of the transmitter. This will
minimize the amount of twisted wire needed to connect the
boundary loop wire to the transmitter.
DO NOT BURY THE WIRE UNTIL YOU HAVE TESTED THE
SYSTEM AND ARE SURE IT IS WORKING PROPERLY.
TAKE CARE NOT TO NICK OR SCRAPE THE WIRE INSU-
LATION DURING INSTALLATION. AN INTERMITTENT
SIGNAL OR NO SIGNAL MAY OCCUR.
Note that some systems, including the SD-2100, feature inter-
nal lightning protection only. If you have one of these sys-
tems, proceed to Section F below.
Other systems, including the SD-2200, feature deluxe exter-
nal lightning protection. If you have one of these systems,
proceed to Section G, Making the Final Connections–SD-
2200 Model Only, below.
F. Final Connections–SD-2100 ONLY
After the transmitter has been installed on the wall and the
boundary wire is in place, the final connections must be
made.
1. Bringing the Outside Wire to the Wall Transmitter -
From the outside, push the twisted pair of wires through the
hole in the exterior wall. A small piece of electrical tape
wrapped around the end of the wire will keep it from untwist-
ing in the wall. Push a sufficient length of wire through the
wall to reach the wall transmitter. Strip about 1/4 inch of insu-
lation from each wire and insert them into the loop wire termi-
nals on the wall transmitter by pushing the orange release
levers on the connector away from the wire terminal holes and
inserting one wire in each terminal. Position the wire along
the wall as desired and push excess wire back out through
the hole in the wall.
2. Splicing to the Boundary Wire - Pull the twisted pair wire
