I don't have it installed on anything.  I do have a story about it though:

Several years ago we installed it in all of our SUN desktops (over 100 
systems) throughout the building we were in.

The fire marshal on our floor received a red plastic fireman's hat as a 
gag gift.  That hat had the most annoying siren on it that any of us had 
ever heard.  So, of course, we recorded a bit of it, looped it, and 
played it throughout the building using nasd.

The help desk lit up like a Christmas tree.  It was the best office gag 
we ever saw.  The sound echoed down the halls on every floor.

We had regular fire drills in that facility, so no one was concerned 
about an alarm type situation.

Management was present and informed prior to procedure.  It was a good 
laugh for all.
