3.5.2 Danger levels
The detector's signal processing efficiently distinguishes between fire events and
deceptive phenomena. The basis for reaching a danger level is not only given by
measured values exceeding a "response threshold"; moreover, the smoke density
progression is observed over a longer period of time and assessed by the
algorithms.
Fire detectors can transmit the following danger levels* to the control panel:
Danger level
Meaning
Comment
0
No danger
Normal condition
1
Check the situation
A different parameter set should
potentially be selected (inappropriate
application)
2
Warning
Possible danger
3
Alarm
Fire
* On a SIGMALOOP detector line, it is the sensor values, not the danger levels,
that are transmitted to the control panel.
The evaluation of the danger level and the decisions to be taken (e.g. activation
of remote transmission) are configured in the control panel.
On a collective detector line, only danger levels 0 and 3 can be transmitted to
the control panel.
