Question 1

Gas concentration exceeds the expected threshold (Carbon Monoxide alarm)

Accepted Answer

Possible cause: Carbon monoxide concentration exceeded threshold (50 PPM within 60-90 minutes, 100 PPM within 10-40 minutes, or 300 PPM within 3 minutes). Immediately ensure abundant ventilation of the room. If possible, turn off the presumed sources of carbon monoxide (gas-powered refrigeration, stoves, combustion engines, etc.) and do not use them until after they have been checked by a specialist engineer. Reset the detector (power off and on); if the alarm is reactivated, evacuate the room. In case of symptoms such as headache, dizziness, nausea, etc., seek immediate medical care.

Question 2

Detector malfunction

Accepted Answer

Possible cause: Malfunction of the electronics or sensor. Replace the device.
