Note:
Be sure all wiring is de-energized before routing.

Firmly mount the base. Depending on local regulations, the
base may be directly surface mounted using anchors, mollies,
or wing-nuts. It may also be mounted to standard 3.5 in.

directly to short lengths (short enough to avoid movement of the
detector) of ½ in. (1.27 cm) EMT.

6.0 LED Operation
The detector uses a tri-color LED to indicate the various alarm and
supervision trouble conditions that may exist. See chart below.

Note:
During walk testing, the LED will light for the first
technology (microwave or PIR) and then light red to
indicate a detector alarm. The LED will not indicate
activation of the second technology by lighting its color.
