I always assumed sprinklers worked on sensors for smoke, like fire alarms.

I guess it makes sense to make it a chemical reaction rather than electronic, there's way less chance of something disarming it without physically removing the chemicals.

I wonder if they can design systems that "override" the little bulb with a line pressure spike or something.

It's always annoyed me in movies when sprinklers are shown to be activated by smoke, like a smoke detector. I can't watch the end of the SpongeBob Movie without grumbling about it.
