8. Locations to Avoid
•
In the garage. Products of combustion are present when you start your automobile.
•
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 install within 1.8 m (6 ft) of heating or cooking appliances.
•
Less than 10 cm (4”) from the peak of an “A” frame type ceiling.
•
In an area where the temperature may fall below 4.4°C (40°F) or rise above 37.8°C (100°F), such as
garages and unfinished attics.
•
In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
•
In very humid areas (above 95% RH, non-condensing). Moisture or steam can cause nuisance alarms.
•
In insect-infested areas.
•
Smoke alarms should not be installed within 0.9m (3 ft) of the door to a bathroom containing 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.
•
Near lights. Electronic “noise” generated by the electronics may cause nuisance alarms.
•
Do not install near vents, flues, chimneys or any forced/unforced air ventilation openings.
•
Do not install near fans, doors, windows or areas directly exposed to the weather.
•
Smoke alarms are not to be used with detector guards unless the combination (alarm and detector
guard) have been evaluated and found suitable for that purpose.
