Technical Specifications
Operating specifications of the gas sensors
The installation of the GS920 detector, its ordinary and extraordinary maintenance, and its out of
service removal at the end of the functional life guaranteed by the manufacturer, must be carried out
by authorized and/or specialized personnel.
The CATALYTIC technology sensor duration is guaranteed for 6 years (in clean air). The detector’s
functioning temperature ranges from -10°C to + 40°C.
WARNING!
The CATALYTIC probe does not tolerate a gas detection exceeding 100% of L.E.L., with consequent
natural death of the sensor.
Each immediate puff of gas that exceeds 100% of L.E.L. takes away months of life from the sensor.
The detector must be tested by simulating the presence of gas by issuing it from a pre-calibrated
testing aerosol.
A common cigarette lighter near the sensor does not guarantee excellent functioning.
Precautions
CHECK the integrity of the probe after having removed it from the box.
Check that the data written on the box correspond to the type of gas used.
When doing the electrical connections, follow the drawing closely.
Any use of the detector for purposes other than the intended one is considered improper, and as a
result of which BEINAT S.r.l. therefore disclaims any responsibility for possible damages caused to
people, animals or objects.
INSTALLATION
When performing the installation, please remind that if you pierce the GS920 container, it will lose
its properties and its conformity to REGULATIONS.
TERMS and EXPECTATIONS: The installation of the GS920 detector, its ordinary and extraordinary
maintenance, and its out of service removal at the end of the functional life guaranteed by the
manufacturer, must be carried out by authorized and/or specialized personnel.
Do not allow it to become wet.
The detector can be seriously damaged when immersed in water. Remember that the probe has an
IP30 protection degree.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoid abrupt temperature fluctuations.
Sudden temperature variations can cause condensation and the probe could work poorly.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.
Absolutely avoid using any cloth dipped in thinners, alcohol and chemical detergents.
