Nest Protect Battery User's Guide
• Near fresh air vents, ceiling fans, or in very
drafty areas. Drafts can blow smoke away
from a smoke alarm, preventing it from
reaching the sensor.
• In insect infested areas. Insects can
clog openings to the sensor and cause
unwanted alarms.
• Less than 12 inches (30.48 cm) away from
fluorescent lights. Electrical “noise” can
interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may
prevent smoke from reaching a smoke alarm.
WHERE NOT TO INSTALL YOUR CO ALARMS
• Keep carbon monoxide alarm at least 5 ft (1.5 m)
away from any cooking appliance including
stovetop, oven, microwave, etc.
• This alarm should not be installed in locations
where the normal ambient temperature is
below 40°F (4.4°C) or exceeds 100°F (37.8°C).
EXAMPLES OF WHEN YOUR SMOKE ALARM
MAY NOT BE EFFECTIVE
Your alarm may not be effective in protecting
against fire in certain cases:
• Smoking in bed
• Leaving children unsupervised
• Cleaning with flammable liquids, like gasoline
• When someone’s clothes have caught on fire
• Fires where the smoke is prevented from
reaching the alarm due to a closed door or
other obstruction
• Incendiary fires where the fire grows so
rapidly that an occupant can’t get out,
evenwith alarms in proper locations
WHERE NOT TO INSTALL YOUR SMOKE ALARMS
For best performance, AVOID installing a smoke
alarm in these areas:
• Where combustion particles are produced.
Burning material creates combustion particles
which could cause your smoke alarm to go off
unnecessarily. Areas to avoid include poorly
ventilated kitchens, garages, boats, recreational
vehicles, and furnace rooms. Keep a smoke
alarm at least 20 feet (6 m) from from the source
of combustion particles (stove, furnace, water
heater, space heater) if possible. In areas where
a 20-foot (6 m) distance is not possible – in
mobile, or smaller homes, for example – it is
recommended a smoke alarm to be placed as far
from these fuel-burning sources as possible. The
placement recommendations are intended to
keep a smoke detector at a reasonable distance
from a fuel-burning source, reducing “unwanted”
alarms. Unwanted alarms can occur if a smoke
alarm is placed directly next to a fuel-burning
source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents
can draw cooking smoke into the sensor of a
smoke alarm near the kitchen.
• In very damp, humid or steamy areas, or
directly near bathrooms with showers. Keep
a smoke alarm at least 10 feet (3 meters) away
from showers, saunas, dishwashers, etc.
• Where temperatures are regularly below
40˚F (4˚C) or above 100˚ F (38˚C) including
unheated buildings, outdoor rooms, porches,
or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not
install a smoke alarm directly over the stove or
range. Clean a laundry room unit frequently to
keep it free of dust or lint.
