Abstract
Stable systems for fire protection have a great importance in fire protection and fire extinguishing. These protection systems can be realized on different ways and with different fire extinguishers. As fire extinguishers, water, CO2, dust, foam, inergen, halon or some "new fire extinguishers"can be used. These protection systems are particularly suitable in cases of fire fighters absence or if they are too far; in cases where big fire spreading and potentials of great damages are very possible; in cases where difficulties of fire spreading with fire mobile equipment exist; in cases where quantity of fire extinguishers in beginning moments are small etc. Systems that possess fire detection in early stage are not in situation to stop the occurrence of fire and its spreading. However, if these systems possess installed extinguishing systems at the existent systems, the potentials fire detection and fire extinguishing are much bigger. This paper has written to present the stable systems for fire protection of Drencher type and FDS computer simulation of extinguishing with this kind of stable fire protection system.
Highlights
Fire protection systems have several different roles in fire protection, such as right timed reaction, early fire detection and protection of human lives and material properties. Some of these systems are systems for fire detection, which implies that they can only detect fire products such as smoke, flame or heat, but without any extinguishing action. These systems can detect fire fast, so, the time needed for the beginning of extinguishing is shorter and results are much better than systems without any kind of fire detection
The same with suitable fire extinguisher. These fire protection systems use different types of fire extinguishers, so, related to that fact, they can be divided on stabile systems that use water as fire extinguisher, stabile systems that use CO2 gas as fire extinguisher, stabile systems that use halons as fire extinguisher, stabile systems that use inergen as fire extinguisher, stabile systems that use dust as fire extinguisher, stabile systems that use foam as fire extinguisher, stabile systems that use pyrotechnic generated aerosols and other [1,2,3,4]
The drencher nozzles were set to 60 l/minute under 3 bars pressure and their reaction temperature were set to 70 ° C [8]
Summary
Fire protection systems have several different roles in fire protection, such as right timed reaction, early fire detection and protection of human lives and material properties. Some of these systems are systems for fire detection, which implies that they can only detect fire products such as smoke, flame or heat, but without any extinguishing action.

These fire protection systems use different types of fire extinguishers, so, related to that fact, they can be divided on stabile systems that use water as fire extinguisher (sprinkler and drencher types), stabile systems that use CO2 gas as fire extinguisher, stabile systems that use halons as fire extinguisher (the different derivatives of halogen elements and carbon), stabile systems that use inergen as fire extinguisher, stabile systems that use dust as fire extinguisher, stabile systems that use foam as fire extinguisher, stabile systems that use pyrotechnic generated aerosols and other [1,2,3,4]
