Sažetak
Fire detectors have a great role in fire protection and present base elements of all systems in real time designed for the measuring of material and energetic occurrences. Fire detectors can be classified according to various factors and different criteria. Fires of some materials produce flames quite quickly. That flame is followed with a very small quantity of smoke, sometimes even none. Because of that, the only practical and effective solution for the detection of such types of fires are flame detectors. Flame detectors can also be used in open spaces and in objects with high ceilings. The main reason for that is the impossibility of smoke detection in given examples (the biggest problems are smoke dilution and convective flow cooling). Such types of fires spread rapidly, so it is important that flame detectors react quickly. For flame detection, infrared and ultraviolet parts of electromagnetic spectrum can be used. This paper was written to present the role of flame detectors in fire protection, and to present the principle of realisation of flame detectors and the rules of the installation of flame detectors arrangement according to valid standards.
