Water-based extinguisher systems (sprinklers)

The name of this extinguisher system comes from the English verb "to sprinkle" and we mean an automatic water extinguishing equipment by that.
A sprinkler equipment is designed to detect fire in an early stage and draw it under control until the fire is completely put out.

A sprinkler systems is built up of the following main components:
-sprinkler heads,
-water pipe system under pressure,
-alarm valves, shut-off valves,
-sprinkler pump(s),
-water storage tank for the sprinkler system.

The sprinklers (sprinkler heads) open up at a predefined temperature (in case of fire) and spray water onto the area underneath. The extinguishing of the fire starts. The water runs through the alarm valves which triggers the fire alarm.
In passive state the sprinklers are closed and the pipe system is under pressure.

The advantages of the equipment:
- Minimal water damage, because only the activated heads open up above the fire, this way the fire extinguishing is targeted.
- Automatic, no need for supervision, permanent standby.
- Fast (instant) alarm.

Experience:
The sprinklers put out 98% of the fires. At 45% of the reported fire cases a single sprinkler was sufficient and only 13% percent of the cases needed ten or more sprinklers open up simultaneously.
