Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.

Ordinary water is used in most fire sprinkler systems. Most fire sprinkler systems are connected directly to the same water you get from the fire hydrant, which is also often the source for drinking water as well.
Over 40 million fire sprinkler heads are fitted each year. A fire sprinkler is a component of a fire sprinkler system that discharges water onto fires in the area once the effects of a fire have been detected, such as excessive increase in temperature.
