We turned in a CAR a long time ago concerning this dangerous feature that
was added some where around version 4.X.  As far as I know, Foxboro has
never provided a fix to provide a standard option for turning off the
ability for the horn to silence when a graphic button is pushed.  I believe
there was a custom fix at one time so I think it would be easy enough for
Foxboro to fix the problem.

Hi Alex,

pressing a button for calling up a display silences also the horn.

Is it possible to disable that functionality?

I would be interested that only pressing the red trumpet button silences =
the horn.

use case: The described functionality avoids that problem that an =
operator could unintentional silence the horn while calling up a =
display. The operator would believe that his colleague manages the alarm =
and all is prepared for a plant shutdown.
 At this time are two different functions (silence a horn and calling up =
a display) mixed.=20


Regards,
Andreas
