Does the unit admit a consent beeping sound when there is a high level of carbon monoxide


Hi Maria, once this alarm detects CO level, it will sound loudly - 4 beeps, pause, 4 beeps, pause and will show LED flashes with the same pattern as the horn. This sequence repeats for as long as the unit is in alarm. - Maria
