What are the basic categories of fire sprinkler systems?

Answer 1

WET, where pipes are full of water, and automatic sprinklers open one at a time if they sense heat

DRY, where pipes are full of air under pressure. when a sprinkler operates air comes out, causing a valve to open and let in water. Used if freezing environments.

PREACTION, where pipes are dry or full of air, and a separate detection system causes the pipes to fill with water. After this it acts like a wet pipe system. Used where accidental water damage might be costly.

DELUGE, where pipes are dry and sprinklers are all open. A separate detection system causes water to flow from all sprinklers at once. Used wher fires are expected to grow quickly and fiercely.

WATER SPRAY SYSTEMS, Like a deluge system, but designed to protect special equipment, like propane storage tanks and cooling towers.

Answer 2

The two catagories for SPRINKLER systems are either wet, which means they already have water in the pipes and are usually automatic, or a dry system, which means the pipes are dry and water needs to be supplied to them manually by an outside source.
