Installation & Operation Manual
Access to the interior of the detector, when carrying out any work, must be conducted by a competent person!
Before carrying out any work ensure local regulations and site procedures are followed!
Always give at least five (5) minutes between testing the same unit or when gas has fully dispersed!
Do not conduct calibration of sensors in conditions outside of any recommended ranges!
To recalibrate a detector, the following procedure and gases must be used!
Calibrated gases must be mixed in accordance with recognised standards such as EN 6142.
If a gas sensor is exposed to a concentration significantly above the measuring range, it should be
recalibrated as soon as possible afterwards!
Contact S&S Northern for more information.
End of Operational Life (EOL)
The typical life of a gas detector depends on its application and intended target gas, in addition, the operational life
can be prolonged if the system and equipment is installed and maintained in accordance the instructions stated within
this manual.
At the end of its predicted operational life – the detector will display an 'End of Life' screen. This
message indicates that the detector has reached its expected operational lifecycle and no gas
levels will be displayed. You must contact your supplier immediately for replacement.
The EOL is approximate from the first five (5) hours of continuous power!
The EOL will depend on the type of gas your detector is targeting and may vary depending on its application
and environmental conditions such as the frequency of exposure to the target gas, poisons or inhibitors!
