3.3.2 Danger levels and warning levels
3.3.2.1 Danger levels for fire detection
The detector's signal processing efficiently distinguishes between fire events and
deceptive phenomena. If the following points apply, a danger level has been
reached:
Measured values above a response threshold
Progression of smoke density, temperature, and CO concentration over a long
period of time
The stated parameters are evaluated using algorithms (CO only with the parameter
sets 'Suppression CO' and 'Balanced CO').
Neural fire detector FDOOTC241 can convey the following danger levels to the
control panel:
Danger level
Meaning
Comment
0
No danger
Normal condition
1
Check situation
A different parameter set for fire
should possibly be selected
(inappropriate application)
2
Warning
Possible danger
3
Alarm
Fire
The evaluation of the danger level and the decisions to be taken (e.g. activation of
remote transmission) are configured in the control panel.
