Assembly & Programming
PIR MOTION SENSOR INSTALLATION
Mount PIR Motion Sensor
horizontally on solid surface
a few feet off the ground and
within 1/2 mile of Base Station
(rotate sensor to access screw
holes). Unit should be able to
swivel as needed.
Attach sun/rain shield.
NOTE:
Keep PIR Motion
Sensor antenna away from
metal objects. Do not mount
PIR Motion Sensor in direct
sunlight, near moving tree
branches, or in the path of a
sprinkler system.
3' - 5'
10' - 20'
Vehicle Alert Installation:
For cars, the best mounting position
is about 4 feet high, between 10-20 feet back, and angled to see
the back of car after passing the sensor.

Troubleshooting
The PIR Motion Sensor lights up, but the Base Station does
not respond.
The PIR Motion Sensor must be programmed to Base Station
(See Step 3). Ensure Base Station is on and the volume is
turned up.
PIR Motion Sensor is detecting motion only part of the time.
Ensure the PIR Motion Sensor is set to the High Sensitivity
setting (See Step 2). To detect cars, it is best to mount PIR
Motion Sensor at height of car’s motor and have it between ten
and twenty feet from the road. Swivel sensor as needed.
The Alert is giving false alarms.
Check for moving tree branches or insects in sensor window.
PIR Motion Sensor can also be triggered by light shining
directly in sensor window, such as refl ected sunlight, or motion
in front of a light source.
It is possible that condensation has built up on the sensor. Wipe
condensation from PIR Motion Sensor with cotton swab. Let it
sit inside for a few hours, open to the air, without the batteries
and it should correct itself.
Check Sensor Switches on PIR Motion Sensor. See Switch
Settings.
Base Station beeps every 30 minutes.
The batteries in the Base Station or the PIR Motion Sensor(s)
are low. Replace the 4 AA batteries. Check the PIR Motion
Sensor(s), if the LED illuminates on all of the PIR Motion
Sensors, change the batteries in the Base Station.
The Alert is not getting expected transmission range.
Keep both antennas vertical and keep PIR Motion Sensor
antenna away from trees and metal objects. Ensure Base Station
is in clearest possible sight of the PIR Motion Sensor. The less
objects between the devices, the longer the range.
