Wireless Driveway Alarm Instruction Manual • 03.04.12
Place the SENSOR immediately next to the driveway to
maximize the sensing range, but at least 25 feet from
roadways, neighbor’s driveways or large moving metal
objects.
The cable connecting the SENSOR and TRANSMITTER
allows for the placement of the TRANSMITTER away from
the driveway in the concealment of landscape or closer
to the RECEIVER.
The approximate transmitting range from the
TRANSMITTER to the RECEIVER is 400 ft. Range can
vary depending on environmental conditions such as RF
interference and topography. Some adjustment may be
required.
NOTE: DO NOT place the TRANSMITTER in the
direct path of a sprinkler. The TRANSMITTER is
water resistant but not waterproof.
If you don’t use the full length of signal cable from
the SENSOR to the TRANSMITTER, coil the extra
cable and bury it beside the transmitter stake.
Installation Overview
Place Driveway Sensor at least
25 ft. from roadways, neighbor’s
driveways to prevent false signals
Senses vehicles and
large moving metal objects
within a 12 ft. radius
ROADWAY
Up to 400 ft. range
from transmitter to receiver
For Optimum Performance:
• Locate the SENSOR as far as possible away from power transformers, power lines,
underground gas line, and telephone lines.
• Locate the SENSOR away from general moving traffic to prevent unwanted activation.
Remember that the SENSOR detects MAGNETIC DISTURBANCES caused by a
vehicle’s mass and velocity.
• Range distance is approximate and will vary due to outside interference, type of soil,
vehicle mass, speed, etc.
• It is recommended that you run the Signal Cable inside PVC conduit to prevent
accidental damage.
• Do not run the Signal Cable in conduit with other wires such as AC power or other
control wires.
• The SIGNAL CABLE CANNOT BE SPLICED.
