In this final paper, I explained the basic characteristics of the making the firefighting documentation and project as a basis for preventing the spreading of fires. All the rules and norms that have been respected during the making of the firefighting project are described. The project has been completely elaborated in the paper in such a way that first the project task itself has been explained followed by the explanation of various problematics. The parts of the system installed in it have been elaborated in detail including their technical characteristics and specifications. The technical part of the project documentation consists of calculations necessary for the making of the system, in a way that calculations of power supply autonomy and conductors have been described in detail, as well as the choice of mounting cables. The technical conditions for construction and the installation of firefighting system have been demonstrated through guidelines and directions. Maintenance instructions and program control along with quality assurance, which enable the user to handle the system easily, play an important role in the system. There is a detailed description of the system in the attached project documentation as well as the calculations of the aerosol concentration necessary for the extinction of the fire and alarm plan.
