ALECTO Carbon monoxide detector (COA3910).

With the Alecto COA3910 carbon monoxide detector in white housing, your home is protected against excessive carbon monoxide levels at all times. Through the handy display you can see the exact concentration of carbon monoxide and the status of the battery. It notifies you via a sound signal and on the display when the carbon monoxide level is too high or when the battery needs to be replaced. However, a low concentration of CO also harms your health; therefore, the device already issues an alert when the carbon monoxide level reaches 30ppm for more than an hour. It is easy to install thanks to the included base plate, screws and plugs. It fits discreetly into your interior thanks to its grainy housing that resembles a plastered wall. It is also very durable, with the sensor lasting for 10 years.
