The positioning of the sensor is an important factor for the correct function of the gas detection
control unit.
In order to obtain the best results and minimize the probabilities of false alarms, we recommend
following this diagram and to keep in mind the following general rules.
The probe should be placed at a height of about 1.60 cm from the ground, if the height of the room
is higher than 2.8m it is recommended to install it at an average height between ceiling and floor.
The sensor should not be fitted where it is likely to be affected by smoke, vapour, etc. as they could
distort indicated measurements.
The sensor must be placed away from sources of heat, suction fans, ventilation fans.
The general test should be performed by issuing gas from a pre-calibrated bottle within the
percentages marked on the bottle information label. Important: This test must be carried out
at least once a year or more frequently if required based on a risk assesment of the setting.
