What do I know, I only operate the things too. Maybe on your railroad but CN does not have any engines where the button/handle that electrically activates the horn has 2 settings. Out of the horns I have blown from other railroads' engines I have never seen that either.
Also, in reality, any crossing that has automatic protection does not need the horn to be blown. I think more people get hit at crossings that are not quiet zones compared to ones that are - both having automatic protection. It's our society. From what I have seen on youtube, North America is really the only place that makes a lot of noise on approach to crossings.
Here in Canada if your horn fails, you don't have to slow down going through a crossing with automatic protection.
