hmm ok, that kinda sounds like what we have in all our science rooms @ school. There's at least 1 big red
button in each room that when hit turns off the
power supplies to the lab benches and cuts the gas
line to all the gas outlets at the benches. They also do some strange stuff to the flame hoods to basicly rip all the air out of them in an attempt to put out any fires inside. All kinda alarms go off too. but ya, I can see how a
system like that would be nice in a theator, obviously with a few differences. (add another thing to to the list of things my
auditorium doesnt have

)
