The next step is to select the “Relay Outputs”

The B40 board should be highlighted in
Green (or other Relay Output board installed

Select the signal that corresponds to the
output wires on the relay board (Y01 for
example).
After selecting the signal, you will need to
assign it to an alarm signal to send. Select

signal to be relayed is wired into the rough-in
box.
There are four choices for the relay output
signal.
