BTC-1 Backup Tone Card Module
Mount on an OCC-1
to provide
a default tone in degrade mode
when communication to the
MXL fails and there is a local
alarm detected.
This is useful
only if the OCC-1 is providing
input to the amplifier.
Note: Mount on an ACM-1
to provide
a backup for the two primary
tones.
