Carlos,
   I am not an expert but I don't see that you have received a reply
to your request, so let me offer a suggestion. I am using F121S's and
F221S's in a repeater application. I believe you have the RX EXO set
correctly. I believe that the "horn" output will either be ground or
floating. You will need to use a pull up resister or voltage divider
resisters to obtain a COS logic state. 
   Hopefully one of the experts will come onboard and offer a more
authoritive answer to your question. If not, let me know. I can
suggest someone who will help.
   Best good luck to you.
