8.4 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.
Configuring
RPS
Walk test is enabled using remote programming software.
Notice!
You should perform a walk test of the full field of view of the detector at least once per year
in order to make sure the detector is performing properly.
8.4.1 Establish the PIR and microwave doppler radar coverage
The 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.
Preparing for the PIR and microwave walk test
1. Remove the detector body from the base.
2. Turn the microwave potentiometer to the minimum range (to the left, counterclockwise).
3. Place the detector body onto the base.
4. Wait at least 2 minutes.
Before you start the test, you can adjust the range for the PIR between short and long range.
Refer to Short/long range.
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 dopper radar or PIR
technologies. During a walk test, the tri-color LED might flash various colors:
–
Red indicates PIR activity only, which is not considered an alarm
– Yellow indicates microwave Doppler radar activity only, which is not considered an alarm
– Blue indicates an alarm condition caused by both PIR and microwave Doppler radar
activity
Performing the walk test and making adjustments
1. Begin the walk test and observe the red LED.
2. If you observe red LED activity while walking along the farthest edge of the desired
coverage area, increase the microwave Doppler radar range. If you observe continuous
activation of the yellow LED activity while walking outside the coverage area, decrease
the microwave Doppler radar range. Remove the detector body from the base and
increase the range by turning the potentiometer clockwise. (Refer to Adjustable
microwave sensitivity for detailed instructions.)
3. Place the detector body onto the base.
4. Wait at least 2 minutes.
5. Repeat walk test procedures and range increase until the PIR and microwave Doppler
radar detection range is as desired.
