It is recommended to bump test detector(s) prior to resetting the service reminder message!

End of Operational Life (EOL)

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!
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 are displayed.
You must contact your supplier immediately for replacement.
