Important Safety Information
• This product is for smoke detection use only.
• This product is NOT designed to connect with
other manufacturers' products unless otherwise
specified.
• This product is not suitable for locations where the
wind speed exceeds 300 meters per minute (985
FPM).
• The unit will not alert hearing-impaired residents.
It is recommended that you install special units
with visual and vibration alarms to alert hearing-
impaired residents.
• It is not recommended for operation in areas where
the temperature may fall below 40
℉
(4.4
℃
) or rise
above 100
℉
(37.8
℃
) or where humidity is higher
than 95%, as this may reduce battery life.
• Do not stand too close to the unit when the alarm
is sounding. It is loud to wake you in an emergency.
Exposure to the noise at close range may harm your
hearing.
• Do not paint over the unit. Paint may clog the
openings to the sensing chamber and prevent the
unit from operating properly.
• Never ignore any alarm. If the unit alarms and you
are not testing it, it is warning you of a potentially
dangerous situation that requires immediate
attention.
• Never remove the battery from the smoke alarm to
stop nuisance alarms.
• Make sure no door or other obstruction could
prevent smoke from reaching the unit. The units
cannot provide an alarm if the smoke does not
reach them.
• Never use an open flame of any kind to test the
smoke alarm. You might accidentally damage or
set fire to the device or to your home.
• You should always replace a smoke alarm aer 10
years from date of purchase.
• Smoke alarms are not to be used with smoke alarm
guards unless the combination has been evaluated
and found suitable for that purpose.

Recommended Locations
This device should be installed in accordance
with the National Fire Protection Association’s
Standard 72 (National Fire Protection
Association, Batterymarch Park, Quincy, MA
02269).
The National Fire Protection Association (NFPA)
recommends installing a smoke alarm in the following
areas:
a. In all sleeping rooms and guest rooms.
b. Outside of each separate dwelling unit sleeping
area, within 21 feet (6.4m) of any door to the sleeping
room, the distance measured along a path of
travel.
c. On every level of a dwelling unit, including
basements.
d. On every level of a residential board and care
occupancy (small facility), including basements
and excluding crawlspaces & unfinished attics.
e. In the living area(s) of a guest suite.
f. In the living area of a residential board & care

Locations to Avoid
For best peormance, please avoid installing a smoke
alarm in these areas:
• In dusty or dirty areas. Dirt and dust can build up
and impair peormance.
• In areas where the normal ambient temperature is
below 40°F (4.4°C) or exceeds 100°F (37.8°C), such as
garages and unfinished attics.
• In highly humid areas. Moisture or steam may
cause nuisance alarms.
• Near fresh air vents, ceiling fans, or in very dray
areas. Dras can blow smoke away from the unit,
preventing it from reaching the sensing chamber.
• In kitchens, garages, and furnace rooms. Burning
material creates combustion particles which could
cause your smoke alarm to go o unnecessarily.
• Less than 4 inches (10 centimeters) from the peak of
an A-frame ceiling. The dead air space may prevent
smoke from reaching the smoke alarm.
• Near fluorescent lights, amateur radios, or other
devices that may transmit an RF signal, as electrical
noise can inteere with the sensor.
