Alarm Reset
To reset after an alarm - press the touch sensor once.
If the device enters an alarm state at any time, the gas level indicator will remain red to alert the user that a
high/dangerous level of gas has been detected, until the device is reset.
Remote Shut Off Indication
A message will display if the device is integrated with remote shut off devices such as smoke or fire alarms etc. When
activated, the device will isolate the gas supply if configured to do so. The mini merlin would need to be reset once
any issues have been investigated and rectified.
Manual Circuit Simulation Test
The manual circuit test does not check the gas sensor itself!
Press and hold the touch sensor during normal operation.
This option gives the user the opportunity to test each relay/output in response to gas.
When the touch button is pressed and held during normal operation the mini merlin will simulate an open circuit to
ensure all configured systems, outputs, alarms, indications, and other external devices operate as intended in
response to gas.
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’
indication on 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.
