4.3.3 Sensor mode 2 – Smoke detector
4.3.3.1 Description
This sensor mode should be selected if fast temperature changes that are not
caused by fire may occur (e.g. in the case of radiant heaters, hot engines). In this
sensor mode the detector only reacts optically; this is comparable with a wide-
spectrum smoke detector. Thanks to a second optical sensor, however, it reveals a
balanced response behavior in relation to the different types of fire.
Universal (1):
With 'Universal' the sensitivity and response time to aerosols are between 'Robust'
and 'Sensitive'.
Robust (2):
This parameter set responds to aerosols in a similar way as the parameter set
'Robust' in sensor mode 0, without taking the temperature into account.
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.
