DLFB is the ideal detector for covering large areas like entrance halls and long distances like corridors. It is also suitable for high buildings, where fire smoke will not be reached by a point detector fixed on the ceiling. It can also substitute point detectors for aesthetic reasons, or simply to limit the number of detectors in an area. Small and streamlined size of the DLFB is really suitable for public buildings like museums, hospitals, and schools. The use of DLFB is the solution for most of the industry’s needs, warehouses, factories, technical galleries or tunnels. Its exceptional coverage from 3m to 100m puts it among the highest performance of the world-wide present market.
