scope:

The European Standard prEN 54-15 specifies requirements, test methods and performance criteria for pointtype multi-sensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996), incorporating in one mechanical enclosure sensors which detect more than one physical or chemical phenomenon of a real fire. The overall fire performance is determined utilising a combination of the detected phenomena. The allowed phenomena are: aerosol (i.e. smoke), heat, combustion gases and electromagnetic radiation. Multi-sensor fire detectors with special characteristics and developed for specific risks are not covered by this standard.
