I'm not a professional with trains sounds, but if you not reset the SIFA you get normally a 'Beep 'or a voice that says 'Zwangsbremsung'. When i didn't reset the SIFA (because i'm stupid to not acknowledge it) i heard the word 'Zwangsbremsung' from the DB BR 182. I don't think that the 204 has the same sound as the 182 in real life. See here the the file of what i'm talking about: https://drive.google.com/file/d/1LyLR43-GLc9y7k5CpxbMiQspiXCJE9J3/view?usp=sharing
