- 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.
- In very high or difficult-to-reach places. Otherwise, testing or cleaning the detector will be very difficult.
- In very dusty and dirty areas. Dust piling up will prevent the smoke from reaching the smoke chamber of the detector and will cause false alarms over time.
- Within 1 meter of dimmers and wiring. Some dimmers may cause the detector to malfunction.
- Within 1.5 meters of fluorescent lamps. Electrical pulses may negatively affect the detector.
- Outside, in rooms with a lot of insects. Small insects in the detector's smoke chamber may cause it to malfunction or give off false alarms.
- In the vicinity/next to decorative objects, doors, electricity boxes, lamps, wall fans etc, that obstruct smoke reaching the smoke detector.
- In places where temperatures can rise above 40 degrees and below 0 degrees. For example, in the attic or just above a fireplace.
