Parameter sets: Sensor mode 2 'smoke detector'

Building Technologies
Fire Safety & Security Products
This sensor mode is especially suited for applications where the detector should
only react thermally.

All parameter sets meet the criteria of standard EN 54-5.
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.
Thanks to a second optical sensor, however, it display an optimized response
behavior in relation to the different types of fire.
Robust (2):
This parameter set reacts to aerosols in a similar way as the neural fire detector
FDOOTC241 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.
