Thanks, you're exactly correct. Of course, those aren't
often used in residences.

"Deluge systems are connected to a water supply through a
deluge valve that
is opened by the operation of a smoke or heat detection
system. The
detection system is installed in the same area as the
sprinklers. When the
detection system is activated water discharges through all
of the sprinkler
heads in the system. Deluge systems are used in places that
are considered
high hazard areas such as power plants, aircraft hangars and
chemical
storage or processing facilities. Deluge systems are needed
where high
velocity suppression is necessary to prevent fire spread."
