0 ppm

The default value is 0 ppm because the natural CO content in the ambient air is about 0.2 ppm. This is rounded to 0 ppm.
So the display always shows the real-time value of the amount of CO, but in a “normal” situation it is simply 0 ppm.

Alarm

If an alarm sounds, immediately move to fresh air and do not enter the premises until it is vented and the CO level returns to a safe level. Investigate the source of the CO release and repair the malfunction. Never ignore an alarm, as CO gas can be deadly in certain concentrations.

Low battery

The battery is low; the detector should be replaced. Contact us to exchange it if it is still under warranty.

Error message

Clean the detector by using a vacuum cleaner with a soft brush and vacuuming all sides and covers of the detector. If the problem persists, the detector is not working properly. Contact us to exchange it if it is under warranty.

Good to know

CO alarm at the right time

A higher concentration of carbon monoxide is regularly released briefly in a home, such as when showering, cooking or when the geyser turns on. With proper ventilation in the home and properly functioning combustion appliances, carbon monoxide levels quickly drop back to “normal” concentrations. In order not to immediately sound the alarm in case of short-term high concentrations, a CO meter contains a timer. The time-weighted value of this is laid down in a European standard, with which our combination detector complies. When the concentration is present for a longer time or when the concentration rises further, the combination detector will alarm.
