An Automatic Sprinkler System can be 1 of 4 different types of systems.
Wet System
Dry System
Deluge and Water Spay System
Pre-action System
Wet Systems are the most common systems and the most simplistic, Wet Systems function with water under pressure within the systems piping. This water is released through a sprinkler head when heat from a fire is detected by the Sprinkler Head.
Dry Systems operate with air present within the piping systems below the water pressure. When a sprinkler head is activated the pressurised air is then released from the piping system resulting in a pressure differential which allows the water to enter the Sprinkler System.
Deluge and Water Spray Systems is a water mist system using open Sprinkler heads attached to a piping system that is connected to a water supply through a valve that is opened by activation of a detection system installed in the same area as the sprinkler heads.
Pre-action Sprinkler System is similar to a Dry System. In a Pre-action system, the water is held back by a Pre-action valve. The valve is opened when heat, smoke, or flame is detected. Two things must happen before a Pre-action system releases water. The first is that the detection system must detect a fire and the valve must open, releasing water into the piping. The second event is that individual sprinkler heads need to open to allow water to discharge.
