Operating modes

Three different modes can be set.
'Automatic: switches between blue and blue-red based on ratio'
This mode is suitable for standard use. The sensitivity to small smoke particles is
high and dust suppression is normal. The particle size is taken into account. This
reduces the likelihood of a false alarm.
'Robust'
This mode is suitable for use in dirty rooms where there is a high dust load. The
sensitivity to small smoke particles is lower, but this results in a higher level of dust
suppression. This makes use possible in a dirty environment or in changing
ambient conditions.
'Ultra sense: always blue'
This mode is suitable for use in clean rooms where there is a low dust load. The
sensitivity to small smoke particles is very high and dust suppression is low. As a
result, the detector is very sensitive even to minor changes relating to smoke or
dust in the intake air.
Parameter sets can be used to make further settings with a view to fine-tuning the
product for the installed pipe system. When making your selection, take the
following into account:
Ambient conditions

Place of installation

Usage conditions

Alarm delay

In the FDnet/C-NET, the operating mode and parameter sets can be configured

from the fire control panel.
To determine suitable parameters, use the recommendations from the

'FXS2055 A6V10340094' software.
