TEXT: FIXED FIRE EXTINGUISHING SYSTEMS

There are fixed extinguishing systems such as automatic sprinkler, drencher and some other systems.

Automatic sprinkler systems should be used for general protection of buildings. They are installed in buildings where serious fires can develop and spread. These systems can automatically detect fires at any time. As they have a fire detection alarm system they give alarm and deliver water to the seat of the fire. Sprinkler systems summon a fire brigade automatically when the first sprinkler head begins to operate.

Drencher systems are installed outside and inside buildings. The purpose of drencher systems is to protect buildings from outside fires, for example, from forest and tank fires and fires from nuclear explosions. The drencher heads protect combustible roofs and window openings. These systems may be operated automatically or manually.

There are also other fixed extinguishing systems such as carbon dioxide, foam, water and dry powder installations. These fixed installations are used for protection of large electrical equipment and plants containing flammable liquids. Besides they are used for protection of hazardous processes in many branches of industry.
