• Avoid the fresh air stream from ventilators or air conditioners. The flow
of air will blow any smoke away from the detector.
Do not place the detector in areas where there may be cause for a false alarm. Avoid:
• Spaces where there is smoke, or similar, as part of everyday life: for
example kitchens or garages.
• Central heating boilers, fireplaces, stoves, cookers, ash trays, toasters.
• Rooms with lots of water vapour/steam, for example bathrooms or
washing areas, especially where this may cause condensation on or
within the detector.
• Spaces where there may be many small insects, for example loft
spaces or greenhouses.
• Spaces where there is a lot of dust. Dust in the air may trigger the smoke detector.
• Air contaminated by solvents, for example thinners, petrol or white spirit.
• Outside areas. Smoke and contaminants can arrive from any distance if
the detector is outside of a building.
Examples
The diagrams on the next three pages summarize some of the good and bad positions for
a smoke detector. The first diagram shows a single floor apartment. The second and third-
diagrams show a small three bedroom- two story house.
