A smoke detector (3 pieces) had now been to 3. x a false alarm (within 4 months), of which 2 were false alarms in the middle of the night. Since I had the smoke detectors mounted with magnetic disks, this could be easily removed. Then the question arose, how do I turn the smoke detector, because there is no switch, and the battery can not be removed. To avoid another night disturbance, the cover was something forcibly removed and interrupted the battery cable. I can only hope that the rest of the smoke detectors work well and safely, but it remains a bad feeling.
