1
Applicable with slow temperature increases <1 K/min.
2
Applicable with fast temperature increases of >10 K/min. When there is a slow temperature
increase of <10 K/min, this value rises by a few degrees.
All parameter sets meet the criteria of standard EN 54-5.
4.6 Default settings
The detector operates in the default parameter set as long as the control panel has
not assigned a valid parameter set to the detector.
The following table shows the default parameter set of the various fire detectors.
