ADICOS GSME
405-2010-003 EN52
FUnCTIOn
4 Function
During operation, the ADICOS GSME monitors the signals of its gas sen
-
sors and triggers an alarm according to the set limit value combina
-
tions. If an ADICOS central unit (ADICOS M-Busmaster) is used, the detector
transmits additionally all sensor and operating data to be displayed in the ADICOS service
software via M-Bus
.
If the detector is connected to a fire alarm panel using an integrated coupling module, the
alarm display of the detector is controlled by the central fire alarm panel.
4.1 Detection
The ADICOS GSME is equipped with fou epending on actuation and evaluation.

The specified cross-sensitivities represent an exemplary selection. Cross-sensitivities must
also be expected in the case if high concentrations of other gases.
Sum signals
To reduce cross-sensitivities, the ADICOS GSME (with respective configuration) calculates
weighted sum signals for detection variables nitrogen oxides (NOx) resp. phenolic hydrocar
