Parameter sets
The detection behavior of the detectors is influenced by the parameter sets, so that
it can be specifically adjusted to the fire phenomena and environmental conditions
to be expected in the environment to be monitored.
The parameter sets for smoke and heat detection are programmed in the
detectors. During commissioning, the optimum parameter set must be selected for
the conditions at the place of installation. This is carried out using the control panel.
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
0
No danger
1
Check the situation.
2
Warning
3
Alarm
The evaluation of the danger level and the decisions to be taken (e.g. activation of
remote transmission) are configured in the control panel.
