Alarm Function
7-1. Gas alarm activation
When the concentration of detected gas reaches or exceeds the alarm setpoint values, a "gas alarm" is

Blinking alarm lamp and buzzer sound operation for gas alarms have different intervals depending on the
detected concentration.
7-2. Fault alarm activation
