Automatic Sprinkler System

The Automatic Sprinkler System has two methods:

A wet pipe sprinkler system uses automatic sprinklers attached to a piping containing water and connected to a water supply so water discharges immediately from sprinklers opened by heat from fire.

Dry pipe sprinklers systems are installed in areas with freezing temperatures, having their piping filled with air or sometimes nitrogen under pressure which keeps the valve closed. Reduction in pressure above the dry pipe valve, caused by an activated individual sprinkler head, allows the water to push open and flow out of the open sprinklers.
