6-1-4 Alarm response
If an alarm is triggered, respond promptly in accordance with the user’s management rules.
The typical procedures are as follows:
Step 1 Check the reading on the product.
CAUTION

In the case of momentary gas leaks, the reading may have already dropped by the time the reading is
checked. The reading may also drop while in a temporary alarm state due to factors other than gas
alarms, such as noise or incidental conditions.
Step 2 Keep all individuals out of the monitored zone to ensure safety in accordance with your alarm
control concentrations.
Step 3 If the concentration display continues, close the main valve for the gas involved and confirm
that the gas concentration reading has fallen.
Step 4 Approach the gas leak location and use a portable gas detector to check for the presence of any
remaining gas.
CAUTION

To avoid hazards while carrying out this work, assume that the gas is still present and wear the
appropriate gear.
Step 5 Once you have determined that no hazard remains, take action to fix the gas leak.
6-2 Fault alarm activation
A fault alarm is triggered if an abnormality is detected in the product.
If a fault alarm occurs, the fault lamp (FAULT) illuminates in yellow, and an error code is displayed as follows:
<In case of sensor abnormality>
FAULT lit (yellow)
NOTE
 After the product has successfully recovered from the fault, it will initialize and restart.
 For more information on fault details (error codes) and appropriate corrective action, refer to
