detectors
During power-up, the anti-mask system learns its environment. Removing objects (such as a
ladder) that are close to the detector can cause an anti-mask alarm.
Resetting anti-mask alarms
If an alarm occurs, after removing the obstruction from the detector you can clear the anti-
mask condition by simply walking in front of the detector after 10 seconds with no activity.
Notice!
During the 10 seconds of quiet time before you can clear the anti-mask condition, the
detector expects no microwave activity in the field of view. If the anti-mask condition doesn't
i
clear after 10 seconds, there might have been some activity in the area which caused only
microwave activity which is not indicated by the LED. Make sure the area is free of any
moving objects, repeat the 10 second wait time, and then move in front of the detector to
clear the anti-mask condition.

Walk test
Before you begin the walk test, review the walk test LED indicator statuses. At the beginning
of the test, with no motion in the protection area, the LED should be OFF. If you observe LED
activity without movement, check for disturbances affecting the microwave or PIR
technologies.
7.6.1
Establish the PIR and microwave coverage
The motion detector PIR and microwave factory settings are optimal for most installations. If
you must adjust the PIR and microwave coverages, use the microwave potentiometer and walk
test to do so.

Remove the motion detector body from the base.
Turn the microwave potentiometer to the minimum range (to the left, counterclockwise).
Place the motion detector body onto the base.
Wait at least 2 minutes.
Begin the walk test and observe the walk test LED.
If you do not observe LED activity while walking along the farthest edge of the desired
coverage area, increase the microwave range. Remove the motion detector body from the
base and increase the range by turning the potentiometer clockwise. (Refer to Adjustable
microwave sensitivity for detailed instructions.)
Place the motion detector body onto the base.
Wait at least 2 minutes.
Repeat walk test procedures and range increase until the PIR and microwave detection
range is as desired.
If on the last walk test, you observe LED activity while walking outside the coverage area,
decrease the microwave range and repeat the walk test.
