Carbon monoxide detector with display

The Alecto COA3920 carbon monoxide detector alerts you immediately in case of carbon monoxide (CO) detection. The detector has a lifespan of up to 10 years. The detector features a stuccoed granular wall texture, making it inconspicuous and blends nicely into almost any interior. Important features - Quick and clear insight via display messages - The 10-year sensor ensures that you are assured of a safe detector for a long time. - The CO detector comes with 3 pieces of AA batteries so you can get started right away. - The carbon monoxide detector alarms at excessive concentrations of carbon monoxide, but also alerts at low concentrations. - The carbon monoxide detector clearly indicates what is going on via display and via sound and the lights. For example, when the batteries are low or the sensor's service life is coming to an end after 10 years. - Supplied complete with base plate, screws and plugs for easy and quick installation. Housing with wall structure The housing of the carbon monoxide detector, also known as CO detector, is strikingly inconspicuous. This is because the detector features a stuccoed granular wall structure. This makes it blend in nicely with almost any wall. The CO detector is compact (78 x 110 x 37 mm) and is suitable for hanging as well as putting down. Also warns of lower concentrations of carbon monoxide Carbon monoxide detectors display the concentration of carbon monoxide in ppm. Ppm stands for parts per million. By law, CO detectors are required to sound an alarm at a detected concentration of carbon monoxide from 50 ppm for 60 minutes. Even when sleeping, an alarm of >85dB will not go unnoticed. However, even a prolonged presence of a lower concentration of CO is harmful to health. The Alecto COA3920 carbon monoxide detector already gives an alert when a concentration of 30 ppm is detected for 60 minutes. Extra insight via the display The display of the COA3920 offers additional insight. For example, the display shows the concentration of carbon monoxide, normally 000ppm. Furthermore, the display offers insight into the battery status and shows notifications in case of too high concentration of CO, test mode and any error messages. Highest quality Like all carbon monoxide detectors from Alecto, these are of the highest quality and comply with the European Standard (EN50291-1:2018). The Alecto COA3920 has a test button with which you can easily test periodically whether the carbon monoxide detector is still working properly. So no more worries about carbon monoxide with this handy CO detector! The Alecto COA3920 is also available in a version without display, model COA1910.
