A rain cover (sold separately) protects the sensor from snow and rain when installed outside.
Blue
Insert the sensor
connector correctly until it
clicks.
Supply the correct voltage
to the sensor.

Remove the moving object
from the detection area.
Reduce the radar sensitivity

Set the presence timer
setting to 30 or 60 seconds.
Remove the highly reflective object
from the detection area or lower the
IR sensitivity volume.

Defective wiring
There is a moving object
in the detection area
The radar sensitivity volume has
been set too high relative to the
installation environment.

After completing installation, walk into the detection area of the sensor. If you feel that the detection
area is incorrect, then adjust it as per section 8. The infrared spot finder SF100 is recommended to
accurately set the infrared detection area.The IR sensitivity volume can also be increased/
decreased if detection problems persist.
If the device detects when there is nothing in the infrared detection area,
turn the sensitivity volume counter-clockwise.
