4 Programming
Programming occurs via a PC or laptop connected to the fire panel
– With FSP-5000-RPS (Remote Programming System) for panels with LSN improved
version line technology
– With WinPara for panels with conventional LSN line technology (not DO-Melder).
420 series detectors are programmed by entering the area of operation. The selection of the
area of operation determines the optimum characteristic field for fire and disturbance
variable evaluation.
When optical sensor sensitivity in the FAP-OTC 420 and FAP-DOTC420 is low, the detector
only triggers if both smoke and an increase in CO concentration or temperature is detected.
The operating mode can be changed for the FAP-OTC 420 and FAP-OT 420 detector models,
as well as the FAP-DOTC420 and FAP-DOT420 models, i.e. individual sensors can be switched
off:
– Switch to optical (O sensor sensitivity = low, T sensor = switched off)
– Switch to thermal differential (T sensor sensitivity = A2R, O sensor = switched off)
– Switch to thermal maximum (T sensor sensitivity = A2S, O sensor = switched off).
In the case of the purely optical FAP-O 420 and FAP-DO420 detectors, the sensitivity of the
optical sensor can be set to three levels. Depending on the operating location, the optical
sensor in the detector is thus adjusted to the environmental conditions.
The FAH-T 420 Heat Detector is programmed by taking into account the ambient temperature,
the installation height and the sensitivity class selection.
Programming of the optical, thermal, and chemical sensors and the linking of all sensors via
algorithms significantly increases the detection ability and security against false alarms.
NOTICE!
For fire detection, the purely optical detector also evaluates the time behavior of the fire
characteristics, which differs significantly from the time behavior of disturbance variables and
that occurring during a detector test
As a result, there are also different trigger times when testing with a test aerosol outside of
Walk test operation (10 s to max 60 s), depending on the selected sensitivity adjustment.
