Callout — Description
1 — For improved catch performance or EN Grade 2 installations, select the high PIR sensitive
setting.
2 — For better false alarm immunity, select the low PIR sensitivity setting.
Adjustable microwave sensitivity
The motion detector has a microwave sensitivity adjustment potentiometer. Use this feature to
adjust the microwave detection range, if necessary.
Notice!
The product ships with the potentiometer pre-set to meet the rated range. In most cases, you
do not need to adjust the potentiometer during the installation. You might adjust the
potentiometer, as instructed, to reduce the potential for false alarms or for very large rooms.
The following figure shows how to adjust the setting using the potentiometer. Turn
counterclockwise to reduce sensitivity.

Self test
The motion detector performs a routine self test every 7 hours, testing both the PIR and
microwave circuit. If either technology fails the self test, the motion detector indicates a
trouble condition by activating the trouble output and the LED 4 flash pattern.
Notice!
A self test fail condition indicates that the detector cannot perform as expected. Replace the
motion detector.
