• Install Smoke Alarms on tray-shaped ceilings (coffered ceilings) on
the highest portion of the ceiling or on the sloped portion of the
ceiling within 12” (305mm) vertically down from the highest point
(Image 2D).
Locations to Avoid
• Do not install within 0.9 m (3') of the following: The door to a
kitchen, or a bathroom that contains a tub or shower, forced
air supply ducts used for heating or cooling, ceiling or whole
house ventilating fans, or other high air-flow areas.
• Do not place the alarm where drapes or other objects will
block the sensor. Smoke must be able to reach the sensor to
accurately detect conditions.
• Do not install in peaks of vaulted ceilings, “A” frame ceilings
or gabled roofs. (Less than 10 cm (4") from the peak of an “A”
frame type ceiling.)
• Install at least 30.5 cm (12") away from fluorescent lights as
electronic noise may cause nuisance alarms.
• Keep out of insect infested areas. Avoid excessively dusty, dirty
or greasy areas. Dust particles may cause nuisance alarms or
failure to alarm.
• Extreme temperatures may effect the sensitivity of the alarm.
Do not install in areas where the temperature is colder than
4.4°C (40°F) or hotter than 37.8°C (100°F), such as garages
and unfinished attics.
• Do not install in areas where the relative humidity (RH) is
greater than 85%. Very humid areas, with moisture or steam,
can cause nuisance alarms.
• Avoid placing ionization smoke alarms in kitchen areas.
Normal cooking may cause nuisance alarms. If a kitchen alarm
is desired, it should have an alarm silence feature or be a
photoelectric type.
• Do not place in the garage. Particles of combustion are
present when you start your automobile.
• Smoke alarms are not to be used with detector guards unless
the combination (alarm and guard) has been evaluated and
found suitable for that purpose.
