Early warning fire detection is best achieved by the installation of fire detection equipment in
all rooms and areas of the household as follows: A smoke alarm installed in each separate
sleeping area (in the vicinity of, but outside of, the bedrooms); and, as appropriate, heat or
smoke alarms in living rooms, dining rooms, kitchens, hallways, attics, furnace rooms, closets,
utility storage rooms, basements and attached garages. Test the alarms weekly to assure
proper operation.
• in extremely dusty, dirty or insect-infested areas. Loose particles interfere with smoke alarm operation.
• in areas where temperature may fall below 40 0 F (4.4 0 C) or rise above 100 0 F (37.8 0 C).
• closer than 1 foot (0.3m) from fluorescent lights, electrical "noise" and flickering may affect the
alarm's operation.
• closer than 3 feet (0.9m) horizontal path from the tip of the blade of a ceiling suspended (paddle) fan.
• on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall).
