In some sprinkler systems, when one goes off, they all go
off. Better to be
wet than blown into the ocean.

Those are known as deluge sprinkler systems. The individual heads are
open and only covered with a light weight dust cover to keep hte heads
clear of accumulations that might interfere with the discharge
pattern. Deluge systems are used to protect occupancies like cotton
mills, explosives and pyrotechnic manufacturing, and aircraft hangers
were there is a danger of flash fire or the ignition of spilled
flammable liquids such that the fire might spread faster than
individual heads would heat up and open to the point that more heads
would open then the system was designed to supply. Deluge sprinklers
are often supplied with foam or other water additives that make them
effective against the particular hazard for which the system is
installed.
