Step-by-step instructions to install and assemble the CO detector.
Simplified visual instructions for installing the CO detector.
Answers to the most common problems.
More on maintenance, cleaning and test and silence mode.
Set the switch on the back of the CO detector to “ON” using the stick provided. The CO detector will beep and the LCD screen will light up blue, then the value will increase from 000 to 999. When the screen is at 0 ppm, the CO detector is activated.
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.
Activate the transmit mode of 1 Aroha Link detector by pressing the test button 4 times within 1 second. For the Aroha Link combination detector, the test button is the entire front of the detector. If this is done correctly, the green LED light will flash in rapid succession for 1 minute. Within this minute you can interconnect this “master” with other linkable Aroha Link smoke, heat, carbon monoxide and combination detectors.
Test mode has been activated, possibly because you have not been able to press 4 times within 1 second.
After the alarm stops, try pressing the test button one more time as quickly as possible within 1 second 4 times.
Press the test button of the other Aroha Link smoke, heat, carbon monoxide and/or combination detector(s) twice within 1 second. This detector will go into receive mode and the green LED will flash slowly to confirm this. If pairing is successful, the green LED on the receiving detector(s) will stop flashing.
If the pairing was not successful, the green LED will continue to flash for 1 minute, followed by a red LED for 2 seconds to indicate that the pairing was not successful. In this case, start the pairing process again.
The Aroha Link detectors have a transmission range of 100 meters without obstructions such as walls, ceilings, doors and windows. You can test if all detectors are interconnected after installation by pressing the test button on one of the Aroha Link detectors; then all test alarms from all interconnected detectors will also sound.
Within 1 second, press the test button on the detector 2 times and the green LED will flash slowly for 60 seconds (receive mode). After this period, the flashing stops and the Aroha Link detector is disconnected.
Test the CO detector by pressing the test button. Then the CO alarm sounds with four short alarms and flashing of the red LED light, followed by a short pause and normally four short alarms and red LED light. Now you know for sure that your CO detector is working properly.
We strongly advise against testing your carbon monoxide detector by making carbon monoxide yourself or exposing it to a carbon monoxide source. Not only is this dangerous to your health, but it can also cause the detector to malfunction. In addition, all Aroha CO detectors are already thoroughly tested in a controlled room at the factory before being released to the market. As a result, you can be confident that your detector will work properly when installed correctly.
Carbon monoxide (CO) and carbon dioxide (CO₂) are two different gases with different properties and risks. Carbon monoxide is a colorless, odorless and highly toxic gas produced by incomplete combustion of fuels such as gas, wood, oil or coal. Even small amounts of carbon monoxide can cause serious health problems and in some cases be life-threatening.
Carbon dioxide, on the other hand, is a colorless and odorless gas that occurs naturally in the air and is produced during complete combustion of fuels and by human respiration. Although a high concentration of CO₂ in enclosed spaces can cause health problems, it is much less dangerous than carbon monoxide and does not cause acute poisoning in normal household situations.
Our carbon monoxide detectors are specifically designed to detect only carbon monoxide (CO). This is because this very gas poses an immediate and serious risk to your safety. It is important to understand that a carbon monoxide detector will not respond to CO₂ because it does not pose a threat in situations where our detectors are used.
Hang the CO detector centrally in the room, at least 30 centimeters from surrounding walls and not next to any present air inlets or air outlets or other objects on the ceiling.
In a room with a combustion appliance (possible CO source), hang the CO detector from the ceiling and at a horizontal distance between 1 and 3 meters from the CO source.
In a room without a combustion appliance, hang the CO detector at breathing height.
Aroha Link detectors have a transmission range of up to 100 meters without obstacles, such as walls, doors and ceilings. Make sure the Aroha Link detectors are within range of each other so they can alarm in sync.
Mount the CO detector with the screw kit by placing the bracket in the desired location and mark the 2 screw holes. Drill these 2 holes with a 5 mm drill head, install the supplied plugs and screw down the mounting bracket. Finally, attach the CO detector to the mounting bracket.
First, clean the area where you want to mount the CO detector by gently wiping it down. Do not use household cleaners such as wipes or sprays as they leave a slippery residue.
Mount the CO detector with the sticky pads by adhering them to the bracket. Then push it onto the desired (smooth) location for 30 seconds. Finally, attach the CO detector to the mounting bracket.

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.
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.
The battery is low; the detector should be replaced. Contact us to exchange it if it is still under warranty.
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.
Test the CO detector once a month.
Clean the CO detector at least once a month to remove dust, dirt or debris. Use a vacuum cleaner with a soft brush and vacuum all sides and covers of the detector.
Do not paint the CO detector, as paint seals the vents and interferes with the sensor’s ability to detect CO.
Do not disassemble the CO detector to e.g. clean the inside or replace the battery, as this will damage the CO detector.
Test the CO detector by pressing the button (= the test button). Then the CO alarm sounds with four short alarms and flashing of the red LED light, followed by a short pause and normally four short alarms and red LED light.
Note: Test the CO detector once a month. Some materials, vapors or gases, can affect the reliability of alarms in the short or long term. Ethylene, ethanol, alcohol, isopropanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide and sulfur dioxide are substances that at high concentrations can damage the sensor or cause temporary readings that are not CO readings. Also most aerosols, alcohol-based products, paint, thinner, solvent, glue, hairspray, aftershave, perfume, car exhaust (cold start) and some cleaning agents.
The battery cannot be replaced. Both the battery and the sensor have the same lifespan. Thus, we recommend replacing the CO detector as soon as the battery runs out.
Do not attempt to replace the battery as this will render the CO detector inoperable and may cause a fire due to the high capacity lithium battery.
Contact us to exchange it if it is still under warranty.
Silent mode should only be used if the source of the alarm is known and safe. Press the test button to set silent mode. During this silence mode, the red LED flashes once every 8 seconds. The CO detector automatically resets after 10 minutes.
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.
