Important Notice for Maintenance
In order to ensure the reliability of the gas detector, it is vital to perform periodic air
adjustment on the gas sensor. It is highly recommended that a maintenance contract with a
local New Cosmos representative be made for the performance of scheduled adjustment
and replacement.
▪
Perform an alarm test in accordance with applicable local laws and regulations. For
example, an applicable law in Japan specifies that alarm activation must be checked by
performing a circuit check once every month.
▪
An alarm test activates the alarm relay contacts of the detector. If the alarm relay contact
outputs are used to interlock external devices, release the interlocks before the alarm
test, as necessary.
Notify those concerned before starting gas detection system inspection.
