Walk Test; Establish The Pir And Microwave Coverage - Bosch ISC-CDL1-WA15G Reference Manual

26 en | Configuration and walk test
Notice!
The anti-mask system can detect objects approximately 30 cm (1 ft) below the motion
detector. Do not mount the motion detector in locations where an object might appear too
close to the unit (for example, above doorways).
Enable or disable the anti-mask feature using the switch labeled 3.

Callout - Description
1 – Anti-mask ON (enabled)
2 – Anti-mask OFF (disabled)
During power-up, the anti-mask system learns its environment. Removing objects (such as a
ladder) that are close to the motion detector can cause an anti-mask alarm.
If an alarm occurs, after removing the obstruction from the motion detector you can clear the
anti-mask condition by simply walking in front of the motion detector after 10 seconds with no
activity.
Notice!
During the 10 seconds of quiet time before you can clear the anti-mask condition, the motion
detector expects no microwave activity in the field of view. If the motion detector does not
clear the anti-mask condition 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 motion detector to clear the anti-mask condition.

Walk test

Before you begin the walk test, review the walk test LED indicator statuses. Refer to Walk test
LED, page 24.
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.
7.4.1

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.
Notice! �
PIR only models �
The microwave information in this section does not apply to ISC-PPR1-W16x models. These
models have a blue LED that indicates PIR alarms. These models do not have a microwave
potentiometer.
