Why Use Alarm Check Valves in a Sprinkler System?

sprinkler system that is specifically used for fire suppression to have alarm check valves throughout.

Contrary to some common misconceptions, alarm check valves are not intended to be used to prevent backflow. These alarm check valves may certainly help prevent water in the sprinkler system from backflowing in the source or a reservoir, thus leading to potential contamination of the water supply, but it's primary purpose is to hold back water pressure in the sprinkler system until such time as it is needed.
