5. LED Operation
The detector uses 3 colored LEDs to indicate the
various alarm and supervision trouble conditions that
that exist. See Table 2.

During walk testing, the LEDs light for the first
technology (microwave or PIR) and then light red to
indicate a detector alarm. The LEDs will not indicate
activation of the second technology with color.
If the detector experiences a Microwave or PIR self-test
failure, it is in need of replacement.
