alarm sounds again. If the concentration sinks to a safe range, then the device
stops the alarm.
8.4 Unlock alarm
To unlock the alarm again, press the "test / hush" button. The carbon monoxide
detector subsequently will work normally again, indicated by the green LED blin-
king every 50 seconds and the display showing the current PPM value.
