5.10.1 Installation of the detector heating unit
When the detector is exposed to icing or moisture condensation (e.g., in cooling
rooms, attics, loading ramps), detector heating unit FDBH291 is installed in the
detector 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.
O
ptimum function of the detector heating unit is only guaranteed with base
attachment wet BA721.
