After only two months, there was the first false alarm. Ironically, when I was at work. The whole house panicked. Particularly annoying this is incomprehensible and unnecessarily loud alarm sound. What do you choose? Then there is no switch. So you have (if you anyway in panic) climb up the ladder and take off all smoke detectors and remove the batteries. And all the while you will be terrorized by this bloodcurdling noise and has afterwards even after an hour of tinnitus.
The manual is also such a joke. There is not even reset the detector, thus making the coupling undo the opportunity. I would prefer - and perfectly adequate - if everyone simply by itself works without radio communication. The noise wakes eh a 10 apartment building with armored doors on when a start. Since you do not need even the crosslinking. You know not what actually triggered the false alarm. Is it because of the batteries? One does not know. I have all the batteries (9V are very expensive) exchanged for nothing.
With this electronic waste I do not want to employ longer, since even a driving test signal in the acoustic madness. So a smoke detector must be as little can. Report only smoke. And that seems to be well demanded for Flamingo too much.
I've now bought something clever of Ei Electronics, with no radio connection, me. Thanks Amazon!
