ADICOS GSME
405-2010-003 EN52
Vibration
Strong vibrations can damage the electronics of the ADICOS GSME detector. If strong vibra
-
tion sources can be found in the surroundings of the planned installation location, the detector
must be positioned such that it is protected from vibrations.
Sensor toxins
Silicone-containing hydrocarbons (siloxanes) can oxidize and thus damage the surface of the
semiconductor gas sensors of the ADICOS GSME detector. No outgassing adhesives, sealants
and lubricants (e.g., silicone) may be used in the surroundings of the detector.
Electromagnetic radiation
Electromagnetic radiation can impact the electronics of the ADICOS GSME detector. Do not
mount the detector in the immediate surroundings of power current equipment. Use shielded
cables only.
5.1.2
Detection aspects
The following aspects must be considered when selecting the installation location to ensure
reliable and sensitive operation of the ADICOS GSME detector.
Building geometry and air flow
The way fire gases propagate depends on numerous factors and is far less intuitive as gener
-
ally assumed. It is thus a particular challenge to ensure that the gas emissions of a smoldering
fire reach the sensors of the detector in sufficient concentration within industrial systems
with complex building geometry, possibly with ventilation systems and machines generating
waste heat.
Thus, all influencing factors of the air flow within the building must be considered when defin
-
ing the installation locations for ADICOS GSME detectors. It may be necessary to perform a fire
test at the location of the expected fire source to identify these factors.
False variables
Different false variables can negatively impact the detector function and lead to false alarms
and sensor aging. No exhaust gases e.g. from conveyor vehicles or fermentation gases from
biological or thermal decomposition must be present at the planned installation location.
