Fair enough.
Offtopic, but I used to rent a room in a huge old row house here in DC with a fancy "networked" fire alarm system. When one goes off, they all go off. You could turn it off by holding a button on the alarm... but it had to be the alarm that went off first. Makes sense from a design standpoint, but as far as I know there was no immediate way to determine which alarm that was, so there was a lot of running around with a broomstick (tall ceilings) pushing buttons.

It was so ridiculous that most people just stopped leaving when a fire alarm went off (the buildings are made of concrete and other not really flammable materials because it's Southern California) but the administration claimed they couldn't turn down the sensitivity.
