Explanation:
Preaction combines both the dry and wet pipe systems and allows manual

The preaction system combines both the dry and wet pipe systems, by first releasing the water into the pipes when heat is detected (dry pipe), then releasing the water flow when the link in the nozzle melts (wet pipe). This allows manual intervention before a full discharge of water on the equipment occurs. This is currently the most recommended water system for a computer room
