Sprinkler System

Sprinkler system is a automatic fire extinguishing system. They detect report and extinguish a fire that is starting, before it grows into a large and uncontrollable blaze. The sprinklers in these systems are attached to network of pipes which covers the areas to be protected in height of the ceiling containing pressurized water at all times. Individual sprinklers in the vicinity of a fire are set off by heat, allowing water to flow through them immediately. Normally each sprinkler is sealed and will only open when it reaches a certain temperature. An important component of the sealing is a glass bulb which is filled with a liquid which will expand when heat from a fire occurs. This robust glass bulb will only burst when the surrounding temperature increases approximately 30 °C above the normal maximum room temperature due to the effects of a developing fire. In this way the pressurized extinguishing water which is free to flow out of the piping network onto the sprinklers spray deflector to be distributed evenly on the fire. At the same time the flow of water created in the pipes triggers the connected alarm systems.

Sprinklers are available at a range of release temperatures and response sensitivities. The area protected by a sprinkler ranges from 9 to 21 m2. The sprinkler type - which can be recognised by the deflector - is selected according to where it is to be fitted.

Types of Sprinkler System

Wet-pipe systems
The wet pipe system is the most common type of sprinkler system. In this type of system, the sprinkler pipe network is completely filled with pressurized water. They are used wherever temperatures are high enough to prevent freezing. when Water freezes pipes expands and this causes water filled pipes to burst and become ineffective. Burst pipes decrease fire suppression capabilities and can cause significant water damage.

Dry pipe system
The dry pipe system is designed especially for areas subject to the danger of frost. The sprinkler pipe network is not filled with water in the critical areas, but rather with compressed air, past the dry alarm valve.

Pre-Action Sprinkler Systems
These systems contain an additional fire-detection device that will recognize a fire before the sprinklers are activated. The sprinklers are attached to a pipe containing air that may or may not be pressurized.

When the detection device senses a fire, it opens the main valve, allowing water to flow through the pipes before the sprinklers are set off. When the heat activates the sprinklers, water flows through immediately, as in a wet-pipe system.

Pre-action systems are usually employed in areas that are at risk for serious water damage due to damaged sprinkles and/or piping.
