An automatic fire-sprinkler system consists of sprinkler heads located throughout the residence and connected to a piping system, which is connected to the municipal or other water supply. When heat produced from a fire reaches a predetermined fixed temperature, it will trip the sprinkler head and discharge water from the piping system to extinguish the fire.
Types of sprinkler systems
The two most prevalent types of automatic sprinkler systems are wet pipe and dry pipe. Wet pipe systems, the most common type, are filled with water at all times. Water will discharge only through sprinkler heads that have been activated.
Dry pipe sprinkler systems are typically used where there is potential for the water in the piping system to freeze, such as in unheated warehouse spaces or large commercial freezer rooms. Water flows into the system only when it is called for.
