In bathrooms, kitchens, showers, garages and so on. These are places where smoke detectors may go off unnecessarily due to condensation, normal smoke or gases. Mount a smoke detector at least 5 meters away from such places.
In areas that are normally warmer or colder than the rest of the room. Temperature differences can prevent smoke from reaching the detector.
Next to or directly above stoves.
