3.1.1 Features of fire detection functionality
As an S-LINE detector, the FDOOTC241 has the following features with regard to
its fire detection functionality:
 Dynamic influence on the parameter sets
 Pattern recognition
 Real time interpretation of the situation
 Process- and time-controlled switchover of the parameter sets
Signal processing is based on ASAtechnology (ASA = Advanced Signal Analysis).
ASAtechnology can also be characterized as second generation algorithms. Signal
processing with ASAtechnology allows for optimum adaptation of detector behavior
to the corresponding ambient conditions.
The S-LINE detectors are characterized by their unique detection reliability and
high immunity to deceptive phenomena.

The signals captured by the sensory are transmitted to the algorithm. The
algorithms are set by selecting the parameter set.
