Sensitivity Adjustment
Permanently Install Sensor and Transmitter
• Once the system is tested and working, remove the
batteries and permanently install the SENSOR, SIGNAL
CABLE and TRANSMITTER.
• Bury the SENSOR approximately 1 ft. deep,
flat and
parallel, next to the driveway.
• Dig a narrow trench or slit from the SENSOR to the
TRANSMITTER location using a flat spade or other
tool. The wire from the SENSOR to the TRANSMITTER
should be at least six inches deep to avoid possible
damage.
• Secure the TRANSMITTER on the supplied 3 piece
PVC pipe by burying the bottom third of the pipe in the
soil and tamping the ground around the pipe. DO NOT
cover the TRANSMITTER with a metal cover as this will
cause signal interference.
• Secure the TRANSMITTER mounting post in the
ground so that the TRANSMITTER is upright and
approximately 1 ft. above ground.
• Replace the batteries.
• The SENSING RANGE can be adjusted from approximately
a 3 to 12 foot radius from the SENSOR.
• The potentiometer varies the sensitivity range of the
SENSOR to avoid unwanted moving metal objects from
activating the alarm, such as: moving gates, metal play
equipment, garage doors, other vehicular traffic, etc.
• With the range adjusted to the maximum of 12 ft., a large
metal object moving slowly will be detected up to 12 ft.
from the SENSOR, while a small metal object moving
slowly might not be detected at the same distance.
Transmitter approximately
1 ft. above ground.
Leave 2-3 inches of wire
slack inside post so the
transmitter can be remove
without pulling plug loose
when changing batteries.
