Building Technologies
Fire Safety
When the detector is exposed to icing or moisture condensation (e.g. in cooling
rooms, attics, loading ramps) the detector heating unit FDBH291 is installed in the
base. The detector heating unit increases the detector temperature by
approximately 2 °C over the ambient temperature and thus avoids moisture
condensation on the detector.
Optimum function of the detector heating unit can only be assured with base
attachment wet FDB295.
