What if you don't have an FBM close by?

Well, now...

Look at file "/usr/fox/alarms/horn.cfg"

You can set up a horn thru a contact output.  The WP
will set the bit you specify here as an "External Horn".
You then need to find a way to clear it.  If you have an
annunciator panel, the point is cleared whenever you hit
one of the Ann Panel display keys, or the Alarm Silence
key.  I think it also clears when you hit the Alarm key
(to call up the alarm summary).

In the absence of a keyboard, and if you want a button for
the operators to hit, you could also hook a button to a
contact input and use a block to clear the horn output
whenever the button input is set.

Really easy, once you understand how the sets and clears work.
