Sensor Placement
Determining Sensor Location
IMPORTANT: Clear an area 25 ft. in all directions of
metal tools, toys and automobiles, to prevent magnetic
disturbance during testing and installation.
• Determine the optimum location for the SENSOR
using the information found in “Installation
Overview.”
• Dig a hole approximately 1 ft. deep and 1 ft. long
within 2 ft. and parallel to the edge of the driveway.
• Place the SENSOR flat in the hole and parallel to
the driveway.
• Keep the SENSOR and the cable uncovered at
this time.

• Choose a location for the TRANSMITTER module that is far
enough from the driveway edge that vehicles are unlikely to
hit it.
• Run the SENSOR cable through the PVC mounting post and
plug it into the connector at the bottom of the Transmitter
module.
• Leave 2” to 3” of slack in the cable to prevent damage to the
connector when the transmitter is removed.
• Test the chosen location before permanently trenching
and setting the TRANSMITTER (see “Placing Receiver and
Testing System” section).
