We had now installed in our apartment 7 of these smoke detectors. The device is very easy and the attachment with the separately ordered Magnetolink well. I can not say anything about the function, because there with us God has not burned thanks ;-) The smoke detectors have but unfortunately still 5 times triggered false alarms, last at 1:00 clock in the night (and unfortunately we do not live in a detached house ...) At first we thought it was a failure and have (which has triggered the alarm) the smoke detector in question sent to Amazon back. Thus, the problem was solved but only for a short time. It looks like that the smoke detectors trigger a complete Low battery. Amazon has the smoke detector thankfully taken back and we get now that no radio!
