All our detectors are tested in special simulation chambers before they leave the factory, so they have already been extensively tested in conditions that do not damage the sensors.

You yourself can test the smoke detector by pressing the test button.The entire front of the smoke detector is the (test) button.

Press the test button briefly and the alarm will go off. Now you know for sure that your smoke detector is working! To turn off the alarm, press the test button again.

Does the alarm not go off? Dust the smoke detector with a vacuum cleaner brush and try again. If the alarm stays off, contact us.

Note: You should only test a smoke detector in a specially designed simulation chamber or with a test spray, to avoid causing any damage to the device or your environment.

Never test your detector with an open flame! This can damage the sensor. Also e.g. cigarette smoke is unsuitable for testing smoke detectors, since the smoke detector does not go off at a light plume of smoke (to prevent false alarms caused by cigarettes, etc.), but at prolonged (several seconds) interruption of the light signal.

Test and clean the smoke detector once a month.
Do not paint the smoke detector, as paint closes the vents and interferes with the sensor’s ability to detect smoke.
Do not disassemble the smoke detector to clean e.g. the inside, as this will damage the smoke detector.

Clean the smoke 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 smoke detector.

To activate the smoke detector, press the entire front of the smoke detector (= test button) until the red LED lights up and a beep tone sounds; this takes at least 10 seconds.
After you release the test button, a green LED light on the front of the smoke detector flashes every minute. The smoke detector is now activated.

The first time the smoke detector is paired, the app may incorrectly display a low battery notification. Please disconnect the smoke detector and then pair it again. If the notification is given again for the app, contact us including screenshot of the notification in the app.

Yes, all smoke detectors we sell comply with the European standard EN 14604. All detectors are also CE approved according to European requirements.
You can find all relevant certificates on the product pages of the respective smoke detector.

Check if there is any danger from smoke and/or fire nearby. Once danger is ruled out, press the test button to set silent mode.

To prevent future false alarms, clean and maintain the smoke detector as directed. Also consider hanging the smoke detector in another location, should it give a false alarm due to e.g. water vapors.

Briefly press the test button on the front of the carbon monoxide detector and the alarm will go off. Now you know for sure that your detector is working! To turn off the alarm, press the test button again.

Does the alarm not go off? Clean the carbon monoxide detector of dust and try again. If the alarm stays off, contact us.

Test and clean the CO detector once a month.
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 clean e.g. the inside, as this will damage the CO detector.

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 of the CO detector.

Using the stick provided, turn the switch on the back of the CO detector to “ON”. 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 first time the smart CO detector is paired, the app may incorrectly display a low battery notification. Disconnect the CO detector and then pair it again. If the notification is given again for the app, contact us including screenshot of the notification in the app.

Yes, all carbon monoxide detectors (CO detectors) we sell comply with European standard EN 50291-2. All detectors are also CE approved according to European requirements.
You can find all relevant certificates on the product pages of the respective CO detectors.

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 the “normal” concentration. 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.

50 ppm

Alarm between 60 to 90 minutes

100 ppm

Alarm between 10 and 40 minutes

300 ppm

Alarm within 3 minutes

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.

Do not paint the combination detector, as paint closes the vents and interferes with the sensor’s ability to detect smoke and CO.
Do not disassemble the combination detector to clean e.g. the inside, as this will damage the combination detector.

Clean the combination detector at least once a month to remove dust, dirt or debris. Use a vacuum cleaner with a soft brush and vacuum all sides of the combination detector.

Rotate the back (mounting bracket) of the combination detector until the lines on the side align, as shown. You can now remove the mounting bracket.
To activate the combination detector, turn the switch on the back of the detector to “ON” and it will beep. The combination detector is now activated.

Check if there are any nearby hazards from smoke and/or fire. If not, open windows and doors to air the room – after all, you can’t see or smell carbon monoxide. Once danger is ruled out, press the test button to set silent mode.

To prevent future false alarms, clean and maintain the combination detector as directed. Also consider hanging the combination detector in another location should it trigger a false alarm due to water vapor, for example.
