Working principle
Preheating :
The detector requires a warm-up time. The “power” lamp lights up in green and
“W-up” lights up in yellow. 4 to 5 minutes after, the yellow light turns off and the
device is fully operational.
Sleep mode and alarm: If no gas is detected, only the green light will remain lit up.
If an abnormal presence of gas is detected, the “Alarm” light switches on and the
alarm rings.
