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.
(1) Check the reading of the alarm system.
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.
(2) Based on your management rules of gas alarm, no one can be allowed to access the monitored
zone to ensure safety.
(3) 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.
(4) 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.
(5) Check that the point is free from dangers, and take actions to fix the gas leak.
6-2. Fault alarm activation
Fault alarm: Triggered when an abnormality is detected in the alarm system.
<Auto-reset> applies to the cases other than the system error "E-00".
When a fault alarm is triggered, the FAULT lamp lights up in orange, an error code appears on
the LCD, and the buzzer sounds. The buzzer sound can be stopped by pressing the
BZ_STOP key.
After the alarm system is successfully returned from the fault, it restarts with the process
normally performed right after it is turned on (initial clear).
When a fault occurred simultaneously with another, the errors are displayed alternately.
If the alarm system has problems and is repeatedly malfunctioning, contact RIKEN KEIKI
immediately.
