<Response to Gas Alarm>
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 gas detector.
NOTE
If a gas leak is momentary, the reading may already have dropped when checking 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 check
that the gas concentration reading is dropped.

Assuming that gases remain, wear protective equipment to avoid dangers and go to the gas leak point,
and then check if gases remain using a portable gas detector etc.

If you can determine that the point is free from dangers, take actions to fix the gas leak.
6-2. Fault alarm activation
A fault alarm is triggered when the gas 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 gas detector is successfully returned from the fault, it restarts with the process normally performed
right after it is turned on (initial clear).
If the gas detector has problems and is repeatedly malfunctioning, contact RIKEN KEIKI immediately.
