Mounting the Control Box


The control box (or transmitter box) is the main control unit for the dog fence.  It creates the signal that goes through the dog fence boundary wire and creates the boundary. From the control box, you can set the boundary width (how far out from the wire the warning and correction start). In some systems like the Innotek IUC-4100 you also set the correction strength at the control box. The control box also includes an indicator that tells you if the fence is operating correctly and will usually sound an alarm if there is a break in the dog fence wire.

Locating the Control Box

The control box needs to be:

  • Near a Power Outlet – preferably, the control box is near an electrical receptacle so you can easily plug it in. If the control box is far from a power outlet, you will need to run an extension cord. When installing a lightning protection module, the power outlet must be grounded (i.e. three prongs instead of two)
  • Near an Exterior Wall – so you can easily run the boundary wire outside.
  • Protected from the Elements – the control box must be sheltered from the elements, particularly moisture. Control boxes (aka transmitters) are not particularly sensitive to cold. Many system manufacturers state that the control box needs to be kept above freezing point, our experience has been that this is not particularly important.


We usually put the control box in some out-of-the-way location like the garage, garden shed, or in a closet/cabinet on the inside of an exterior wall. After completing the initial installation, you will rarely use the control box, so ease of access is not particularly important.

Weatherproof Box

You can also put the control box outside in a weatherproof box. Weatherproof enclosures can be found at any hardware store, and are found in the electrical section. The weatherproof box provides extra protection if you are placing a control box outside under an eave or on a deck.

Mounting the Control Box

Screw the transmitter box to the wall using the supplied mounting screws. If you are mounting onto drywall or masonry, you will need to use the appropriate anchors to get a secure mount. Control boxes are light (around 1 lb), so there is no need to mount them directly into a stud.

Installing the Lightning Protection (optional)

In geographic regions that experience frequent lightning strikes, or for large installations (over 5 acres), it is worth installing the lightning protection module. The module is included in the Innotek IUC-5100 and the PetSafe Little Dog Fence systems. In all other systems, it is available for an additional $40.

The lightning protection module plugs directly into any grounded power outlet. Instead of the boundary wire connecting directly to the control box, the two boundary wires connect directly to the lightning protection module. Two wires are then used to connect the lightning protection to the control box. This configuration protects the control box from surges originating from the boundary wire or surges originating from your home’s electrical system.

Getting the Wire Outside

If the control box is mounted indoors, you need to run the wire outside. If there is some convenient venting or wiring already running outside, then use this opening to run the dog fence wiring. You can also run the wire through a window, or under a garage door. Do not run the wire through dryer ducting. Dryer vents get very hot when the dryer is in use and the insulation on the boundary wire will melt when exposed to this heat.

For most installations, the easiest way to get the wire outside is to drill a hole through the wall, pull the wire through the hole, then caulk the hole to ensure a good seal. Exterior silicone caulk works great for this application.
