I think the problem is that how you should handle the fire alarm is
very complex because you need to ensure that people can get out
quickly, and the fire brigade can get in, without having to security
clear every fire officer...... quite a problem. I guess what should
happen is.

1. Fire Alarm Goes Off
2. All Exits and Entrances open.
3. All Computer's auto lock down and shut down, automatically and can
not be accessed until the building is secured again. (and do it zone
by zone)
4. Text Message you fire Marshells with the head count, and phone the
fire brigade (Again automatic) and maybe even produce a list and get
it to a remote location.
5. Ideally count the people out (Quite easy just some kind of weight
strip on all the doors) and if you hit zero you can save the fire
brigade major risk because you know the building is empty sooner...

Of course its all totally floored but so is every system anyone will
ever come up with.
