Subdividing elements and different structures on the ceiling like beams or similar, significantly affect the location of the smoke detector, because they change the flow of combustion products. From point of view of fire detection system designers it is very interesting how to arrange and distribute smoke detectors in applications when beams are formed structure like a “honeycomb”. The main goal of this paper is to show the differences between rules and instructions in five standards: EN 54-14, VDE 0833-2, BS 5839-1, НПБ 88, NFPA 72, and to find the best solution for various situations in practice.
