All parameter sets meet the criteria of standard EN 54-5.
4.2.4 Parameter sets: Sensor mode 2 'Smoke detector'
4.2.4.1 Description
Select sensor mode 2 when fast temperature changes may occur which are not
caused by fire (e.g. radiant heaters, hot engines). In this sensor mode the detector
only reacts optically; this is comparable with a wide-spectrum smoke detector.
However, because it has a second optical sensor, it reveals an optimized response
behavior in relation to the different types of fire.

Robust (2):
This parameter set responds to aerosols in a similar way as the neural fire detector
in sensor mode 0 with the 'Robust' parameter set, without taking into account the
temperature.
Universal (1):
With 'Universal' the sensitivity and response time to aerosols are between 'Robust'
and 'Sensitive'.
Sensitive (3):
With regard to aerosols, this parameter set reacts in a way that is comparable to
'Fast Response' in sensor mode 0 without temperature influence.
All parameter sets meet the criteria of standard EN 54-7.
