[BC] TFT EAS 911D

[Kyle Magrill, CircuitWerkes Support]

You can't sum inputs to an EAS because the audio from one 
source will mask the EAS message from the other.  To work, 
the EAS decoder has to scan each input looking for the header, 
then lock to the source when the header is detected.   TFT makes 
input expander cards for the regular EAS911.  Not sure about the "D".

"In going through the rules, I see nothing that
would prohibit summing two radios to one input,
and then using the second input of the 911D for
the CAP service with a converter, which may be
available...."
