WHERE NOT TO INSTALL YOUR SMOKE AND HEAT
DETECTORS
False alarms occur when smoke and heat detectors are installed where they will not work
properly. To avoid false alarms,
do not
install smoke and heat detectors as follows:
In the path of fresh air intake. The in-and-out flow of fresh air can drive smoke away
from the smoke and heat detector; thus reducing its efficiency. Figure 6 indicates the
correct and incorrect locations concerning this problem.
Near paint thinner fumes.
In close proximity to an automobile exhaust pipe, as this will damage the detector.
In very cold or very hot areas,
including unheated buildings or
outdoor rooms. If the temperature
goes above or below the detection
range of the smoke and heat
detector, it will not work properly. This
detection range is 40°F to 100°F (4°C
to 38°C).
Near fresh air vents or very drafty
areas like air conditioners, heaters or
fans. Fresh air vents and drafts can
drive smoke away from smoke and
heat detectors.
Dead-air spaces, which are often at
the top of a peaked roof, or in the
corners between ceilings and walls.
Dead air may prevent smoke from
reaching a detector. See Figures 8
and 9 for recommended mounting
locations

detector locations
In insect-infested areas. If insects enter a detector's sensing chamber, they may
cause a false alarm. Where bugs are a problem, get rid of them before putting up a
detector.
Near fluorescent lights, as electrical "noise" from fluorescent lights may cause false
alarms. Install smoke and heat detectors at least 5 feet (1.5 meters) from such lights.
