other reliable means of escape from an upper floor in case stairs are
blocke .
BEFORE YOU INSTALL THIS SMOKE ALARM
Important! Rea “Recommen e Locations for Smoke Alarms” an
“Locations to Avoi for Smoke Alarms” before beginning. This unit
monitors the air, an when smoke reaches its sensing chamber,
it alarms. It can give you more time to escape before fire sprea s.
This unit can ONLY give an early warning of eveloping fires if it is
installe , maintaine an locate where smoke can reach it, an where
all resi ents can hear it, as escribe in this manual. This unit will not
sense gas, heat, or flame. It cannot prevent or extinguish fires.
Understand The Different Type of Smoke Alarms
Battery powere or electrical? Different Smoke Alarms provi e
ifferent types of protection. See “About Smoke Alarms” for etails.
Know Where To Install Your Smoke Alarms
Fire Safety Professionals recommen at least one Smoke Alarm on
every level of your home, in every be room, an in every be room
hallway or separate sleeping area. See “Recommen e Locations
For Smoke Alarms” an “Locations To Avoi For Smoke Alarms” for
etails.
Know What Smoke Alarms Can and Can’t Do
A Smoke Alarm can help alert you to fire, giving you precious time to
escape. It can only soun an alarm once smoke reaches the sensor.
See “Limitations of Smoke Alarms” for etails.
Check Your Local Building Codes
This Smoke Alarm is esigne to be use in a typical single-family
home. It alone will not meet requirements for boar ing houses,
apartment buil ings, hotels or motels. See “Special Compliance
Consi erations” for etails.
HOW TO INSTALL THIS SMOKE ALARM
THE PARTS OF THIS SMOKE ALARM FOLLOW THESE SIMPLE STEPS:
*All First Alert®Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at etecting small particles, which ten to be pro uce
in greater amounts by flaming fires, which consume combustible
materials rapi ly an sprea quickly. Sources of these fires may inclu e
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at etecting large particles, which ten to be pro uce
in greater amounts by smol ering fires, which may smol er for
hours before bursting into flame. Sources of these fires may inclu e
cigarettes burning in couches or be ing.
For maximum protection, use both types of Smoke Alarms on each
level and in every bedroom of your home.
• This unit will not alert hearing impaired residents. It is recom-
mended that you install special units which use devices like
flashing strobe lights to alert hearing impaired residents.
• Do not connect this unit to any other Alarm or auxiliary
device. It is a single-station unit that cannot be linked to other
devices. Connecting anything else to this unit may prevent it
from working properly.
• Unit will not operate without battery power. The Smoke Alarm
cannot work until you activate the battery power pack.
• Do not install this unit over an electrical junction box.
Air currents around junction boxes can prevent smoke from
reaching the sensing chamber and prevent the unit from
alarming. Only AC powered units are intended for installation
over junction boxes.
• 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 horn
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.

RECOMMENDED LOCATIONS FOR
SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommen s one
Smoke Alarm on every floor, in every sleeping area, an in every be -
room. In new construction, the Smoke Alarms must be AC powere an
interconnecte . See “Agency Placement Recommen ations” for etails.
For a itional coverage, it is recommen e that you install a Smoke
Alarm in all rooms, halls, storage areas, finishe attics, an basements,
where temperatures normally remain between 40˚ F (4.4˚ C) an 100˚ F
(37.8˚ C). Make sure no oor or other obstruction coul keep smoke
from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
•
On every level of your home, inclu ing finishe attics an basements.
• Insi e every be room, especially if people sleep with oors close .
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is over 40 feet (12
meters) long, install an Alarm at each en .
• At the top of the first-to-secon floor stairway, an at bottom of
basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state an from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/DC
units be interconnected for added protection.

California State Fire Marshal (CSFM)
Early warning etection is best achieve by the installation of fire
etection equipment in all rooms an areas of the househol as follows:
A Smoke Alarm installe in each separate sleeping area (in the vicinity,
but outsi e be rooms), an Heat or Smoke Alarms in the living rooms,
ining rooms, be rooms, kitchens, hallways, finishe attics, furnace
rooms, closets, utility an storage rooms, basements, an attache
garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you AVOID installing
Smoke Alarms in these areas:
• Where combustion particles are pro uce . Combustion particles
form when something burns. Areas to avoi inclu e poorly ventilate
kitchens, garages, an furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6-meter) istance is not possible – in mo ular, mobile, or smaller
homes, for example – it is recommen e the Smoke Alarm be
place as far from these fuel-burning sources as possible. The
placement recommen ations are inten e to keep these Alarms at
a reasonable istance from a fuel-burning source, an thus re uce
“unwante ” alarms. Unwante alarms can occur if a Smoke Alarm
is place irectly next to a fuel-burning source. Ventilate these
areas as much as possible.
•In air streams near kitchens. Air currents can raw cooking smoke
into the sensing chamber of a Smoke Alarm near the kitchen.
•In very amp, humi or steamy areas, or irectly near bathrooms
with showers. Keep units at least 10 feet (3 meters) away from
showers, saunas, ishwashers, etc.
• Where the temperatures are regularly below 40˚ F (4.4˚ C) or above
100˚ F (37.8˚ C), inclu ing unheate buil ings, out oor rooms,
porches, or unfinishe attics or basements.
• In very usty, irty, or greasy areas. Do not install a Smoke Alarm
irectly over the stove or range. Keep laun ry room Smoke Alarms
free of ust or lint.
•Near fresh air vents, ceiling fans, or in very rafty areas. Drafts can
blow smoke away from the unit, preventing it from reaching the
sensing chamber.
•In insect infeste areas. Insects can clog openings to the sensing
chamber an cause unwante alarms.
• Less than 12 inches (305mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
•In “ ea air” spaces. “Dea air” spaces may prevent smoke from
reaching the Smoke Alarm.
Avoiding Dead Air Spaces
“Dea air” spaces may prevent smoke from reaching the Smoke Alarm.
To avoi ea air spaces, follow the installation recommen ations
below.
On ceilings, install Smoke Alarms as close to the center of the ceiling
as possible. If this is not possible, install the Smoke Alarm at least 4
inches (102 mm) from the wall or corner.
For wall mounting (if allowe by buil ing co es), the top e ge of
Smoke Alarms shoul be place between 4 an 12 inches (102 an
305 mm) from the wall/ceiling line, below typical “ ea air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measure
horizontally. A itional Smoke Alarms may be require epen ing on
the length, angle, etc. of the ceiling's slope. Refer to NFPA 72 for
etails on requirements for slope or peake ceilings.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, con ominiums,
townhouses, hospitals, ay care facilities, health care facilities, boar ing
houses, group homes an ormitories provi e a primary fire etection
system alrea y exists to meet fire etection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provi e sufficient warning to all resi ents or
meet local fire protection or inances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
etection systems in places housing many people—like apartment
buil ings, con ominiums, hotels, motels, ormitories, hospitals, health
care facilities, nursing homes, ay care facilities, or group homes of any
kin . It is not a suitable substitute for complete fire etection systems
in warehouses, in ustrial facilities, commercial buil ings, an special-
purpose non-resi ential buil ings which require special fire etection
an alarm systems. Depen ing on the buil ing co es in your area, this
Smoke Alarm may be use to provi e a itional protection in these
facilities.
In new construction, most buil ing co es require the use of AC or
AC/DC powere Smoke Alarms only. In existing construction, AC,
AC/DC, or DC powere Smoke Alarms can be use as specifie by
local buil ing co es. Refer to NFPA 72 (National Fire Alarm an
Signaling Co e) an NFPA 101 (Life Safety Co e), local buil ing co es,
or consult your Fire Department for etaile fire protection requirements
in buil ings not efine as “househol s”.
LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have playe a key role in re ucing eaths resulting from
home fires worl wi e. However, like any warning evice, Smoke Alarms
can only work if they are properly locate , installe , an maintaine ,
an if smoke reaches them. They are not foolproof.
Smoke alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involve – from
ki s to gran parents. Allow chil ren to master fire escape planning an
practice before hol ing a fire rill at night when they are sleeping.
If chil ren or others o not rea ily waken to the soun of the Smoke
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigne to assist them in fire rill an in
the event of an emergency. It is recommen e that you hol a fire rill
while family members are sleeping in or er to etermine their response
to the soun of the Smoke Alarm while sleeping an to etermine
whether they may nee assistance in the event of an emergency.
Smoke Alarms cannot work without power. Battery operate units
cannot work if the batteries are missing, isconnecte or ea , if the
wrong type of batteries are use , or if the batteries are not installe
correctly. AC units cannot work if the AC power is cut off for any reason
(open fuse or circuit breaker, failure along a power line or at a power
station, electrical fire that burns the electrical wires, etc.). If you are
concerne about the limitations of battery or AC power, install both
types of units.
Smoke Alarms cannot detect fires if the smoke does not reach
them. Smoke from fires in chimneys or walls, on roofs, or on the other
si e of close oors may not reach the sensing chamber an set off the
alarm. That is why one unit shoul be installe insi e each be room or
sleeping area—especially if be room or sleeping area oors are close
at night—an in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the
home. For example, a stan -alone unit on the secon floor may not
etect smoke from a basement fire until the fire sprea s. This may not
give you enough time to escape safely. That is why recommen e
minimum protection is at least one unit in every sleeping area, an every
be room on every level of your home. Even with a unit on every floor,
stan -alone units may not provi e as much protection as interconnecte
units, especially if the fire starts in a remote area. Some safety experts
recommen installing interconnecte AC powere units with battery
back-up (see “About Smoke Alarms”) or professional fire etection
systems, so if one unit senses smoke, all units alarm. Interconnecte
units may provi e earlier warning than stan -alone units since all units
alarm when one etects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit
meets or excee s current stan ar s, it may not be hear if: 1) the unit
is locate outsi e a close or partially close oor, 2) resi ents recently
consume alcohol or rugs, 3) the alarm is rowne out by noise from
stereo, TV, traffic, air con itioner or other appliances, 4) resi ents are
hearing impaire or soun sleepers. Special purpose units, like those
with visual an au ible alarms, shoul be installe for hearing impaire
resi ents.
Smoke Alarms may not have time to alarm before the fire itself
causes damage, injury, or death, since smoke from some fires may
not reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
Smoke Alarms are not foolproof. Like any electronic evice, Smoke
Alarms are ma e of components that can wear out or fail at any time.
You must test the unit weekly to ensure your continue protection.
Smoke Alarms cannot prevent or extinguish fires. They are not a
substitute for property or life insurance.
Smoke Alarms have a limited life. The unit shoul be replace
imme iately if it is not operating properly. You shoul always replace a
Smoke Alarm after 10 years from ate of purchase. Write the purchase
ate on the space provi e on back of unit.
