• The LED is turned on every 3.75 seconds (every 20 seconds in normal state).
• When the following conditions are satisfied, the buzzer issues an alarm.
The carbon monoxide concentration is 50 ppm or more for 15 seconds (60 minutes in the normal state).
The carbon monoxide concentration is 100 ppm or more for 7.5 seconds (10 minutes in the normal state).
The carbon monoxide concentration is 300 ppm or more for 3.75 seconds (3 minutes in the normal state).
