Use only the provided Class II AC Adapter with output 24VDC, 1A.

!
For installations with more than one MCU, use an outlet strip with a built
in power switch. This allows the MCUs to be turned on and off together.
2. Plug the AC adapter into a 110VAC outlet or switch on the outlet strip to apply
power to the MCU.
Set Switch Interface Type
The following steps explain how to assign a switch interface type to the MCU. This
procedure
must be done in on each MCU
.
1. Power on the MCU with the Mode Switch in the
NORMAL
position.
Because the MCU does not have a switch type assigned, it will alarm (the Error
LED will flash along with Status LEDs 1,2,3,4 and 5). This should take less than
2 minutes.
2. Power off the MCU.
3. Move the Mode Switch to
ADMIN
and power on the MCU. Within 15 seconds,
Status LEDs 2 and 4 will light.
4. Press the
STEP
button three times.
Status LEDs 1, 2 and 4 must be lit. Line LEDs 1 through 8 (indicating an
unconfigured MCU) should also be lit.
If any other combination of Line LEDs is lit, then a switch type has already been
selected. Go to step 5 to pick the desired switch type.
5. Press the
DEL/ENTER
button to select the correct switch interface type. With
each press of the
DEL/ENTER
button, a different series of Line LEDs will be lit.
Continue to press
DEL/ENTER
until the correct Line LEDs are lit. Use the
following list to select the desired switch interface.
