In case of responding to a leaked gas
When a gas alarm is triggered, take actions in accordance with your management rules of gas alarm.
Normally, take the following actions.
• Check the reading of the detector.
NOTE
If a gas leak is momentary, the reading may already have dropped when you check it. In addition, when the
alarm is triggered by noise or other incidental conditions other than a gas, the reading may have already
dropped.
• Based on your management rules of gas alarm, no one can be allowed to access the monitored zone to
ensure safety.
• If the Gas Concentration Display continues to be shown, close the main valve of the gas, and then verify
that the gas concentration reading dropped.
• Equipped with a protective gear to avoid dangers caused by possibly remaining gases, before accessing
the gas leak point, and then check whether gases remain by using a portable gas detector.
• If you can determine that the point is free from dangers, take actions to fix the gas leak.
4-2. Fault alarm activation
A fault alarm is triggered when the detector detects abnormalities.
After a fault alarm is triggered, the FAULT lamp (yellow) lights up
and an error message is displayed on the LCD. Determine the
causes and take appropriate actions.
After the detector is successfully returned from the fault, it
restarts with the process normally performed right after it is
turned on (initial clear).
If the detector has problems and is repeatedly malfunctioning,
please contact us immediately.
