This sets the minimum current that must be
drawn by a VAA from its battery on LINE 1
in order for the VAA to confirm that it has
sounded the pre-start alarm. This can be set
to such a level as to indicate that one of the
VAA’s two speakers has failed. See the Pre-
Start Alarm chapter for more information

or
[None]
This is the number of VAA’s that are
connected to the LINE 2. This is the number
of VAAs that the VCA should be able to
communicate with. If no VAAs are
connected, then this is set to None.
Line 2 Service
