If it's like the Federal system I took care of, I would doubt that it's 
daisy chained. Although I did like testing it using the Westminster 
Chimes tone. Of course the first thought through my mind was that while 
it was close, if you used the theme from Close encounters of the third 
kind, everyone would know it was a Alien event even before you got to an 
announcement.
