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:
A different parameter set should
potentially be selected (inappropriate
application)
* 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.
