Signal processing of the point detectors is based on ASA
technology (ASA =
Advanced Signal Analysis). ASA
technology can also be characterized as "second
generation algorithms". Signal processing with ASA
technology allows for optimum
adaptation of detector behavior to the corresponding ambient conditions.
Point detectors with ASA
technology are characterized by their unique detection
reliability and very high resistance to deceptive phenomena.

Sensory
The signals captured by the sensory are transmitted to the algorithm. The
algorithms are set by selecting the parameter set.
Algorithms
The individual parameters in the selected parameter set can be adapted with
ASA
technology. A real time interpretation of the situation leads to a dynamic
influence on the algorithm. This results in the parameter set's and therefore the
point detector's application range broadening. The detector reacts more sensitively
in the event of fire, and more robustly in the event of deceptive phenomena.
