FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations: 1) Use smoking
m
aterials properly. Never smoke in bed. 2) Keep matches or lighters
away fr
om childr
e
n; 3) Store
flammable materials in pro
per containers;
4) Keep electrical appliances in good condition and don’
t overload elec-
t
rical circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys
grease- and debris-free; 6) Never leave anything cooking on the stove
unattended; 7) Keep portable heaters and open flames, like candles,
away from flammable materials; 8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen. Have fire escape ladders or
other reliable means of escape from an upper floor in case stairs are
blocked.
BASIC SAFETY INFORMATION
•
Dangers, Warnings, and Cautions alert you to impor
tant
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
•
This Smoke/CO Alarm is approved for use in single-family
residences. It is NOT designed for marine or RV use.
•
This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that r
eaches the sensor
. The Smoke Alarm
is not designed to sense gas, heat or flames.

S
moke Alarms conform to regulatory
r
e
quire
ments, including UL217 and are
designed to detect part
icles
of combustion. Smoke particles of varying number and size are
p
roduced in all fires.
Ionization technology is generally mor
e
sensitive than photo-
electric technology at detecting small particles, which tend to be
p
ro
duced in greater amounts by flaming fires, which consume
combustible materials rapidly and spread quickly. Sources of these
fir
e
s may include paper burning in a wastebasket, or a grease fire in
t
he kitchen.
P
hotoelectric technology is generally more sensitive than ionization
t
echnology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
h
ours before bursting into flame. Sources of these fires may include
c
igarettes burning in couches or bedding.
For maximum pr
otection, use both types of Smoke Alar
ms on
e
ach level and in every bedroom of your home.
•
This unit will not aler
t hearing impair
ed r
esidents. It is
r
ecommended that you install special units which use devices
like flashing str
obe lights to aler
t hearing impair
ed r
esidents.
•
This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• The battery compartment resists closing unless a battery is
installed. This war
ns you the unit will not operate without a
battery.
• 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 chambers and prevent the unit from operating properly.

I
NSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
N
ational Fire Protection Association (NFPA), is one Smoke Alarm on
e
very floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
e
ach separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
I
n general, install combination Smoke and Carbon Monoxide
A
larms:
• On every level of your home, including finished attics and basements.
•
Inside every bedroom, especially if people sleep with the door partly
o
r completely closed.
• In the hall near every sleeping area. If your home has multiple
s
leeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
•
At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
•
For additional coverage, install Alarms in all rooms, halls, and storage
areas, where temperatures normally remain between 40˚ F and
100˚ F (4˚ C and 38˚ C).
R
ecommended Placement
•
When installing on the wall, the top edge of Smoke Alarms should
b
e placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the
c
enter as possible.
•
In either case, install at least 4 inches (102 mm) from where the
w
all and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
N
OTE:
F
or any location, make sure no door or other obstruction could
k
eep carbon monoxide or smoke from reaching the Alarm.
I
nstalling Smoke/CO Alarms in Mobile Homes
F
or minimum security install one Smoke/CO Alarm as close to each
s
leeping area as possible. For more security, put one unit in each room.
Many older mobile homes (especially those built befor
e
1978) have little
o
r no insulation. If your mobile home is not well insulated, or if you are
u
nsure
of the amount of insulation, it is important to install units on
inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
D
o NOT locate this Smoke/CO Alarm:
•
In garages, kitchens, furnace rooms, crawl spaces and unfinished
attics. Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
f
orm when something burns. Areas to avoid include poorly ventilated
k
itchens, garages, and furn
ace ro
oms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
w
ater heater, space heater) if possible. In areas where a 20-foot
(
6 meter) distance is not possible – in modular,
mobile, or smaller
homes, for example – it is r
ecommended the Smoke/CO Alarm be
p
laced as far from these fuel-burning sources as possible. The
p
lacement re
commendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“
unwanted” alarms. Unwanted alarms can occur if a Smoke/CO
A
larm is placed dire
ctly next to a fuel-burn
ing sourc
e. Ventilate
these areas as much as possible.
•
Within 5 feet (1.5 meters) of any cooking appliance. In air str
e
ams
near kitchens. Air currents can draw cooking smoke into the smoke
s
ensor and cause unwanted alarms.
•
In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry r
oom, utility r
oom, or other sour
ce of high humidity
.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
m
ay prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4˚ C) or hotter than
100˚ F (38˚C). These areas include non-airconditioned crawl spaces,
unfinished attics, uninsulated or poorly insulated ceilings, porches,
and garages.
•
In insect infested areas. Insects can clog the openings to the
sensing chamber.
•
Less than 12 inches (305 mm) away from fluor
escent lights.
Electrical “noise” can interfere with the sensor.
•
In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke fr
om r
eaching the Smoke/CO
Alarm. T
o avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or cor
ner
.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line.
On a peaked, gabled, or cathedral ceiling, install the first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measur
ed
horizontally
. Additional Smoke/CO Alarms may be r
equir
ed depending
on the length, angle, etc. of the ceiling's slope. Refer to NFPA 72 for
details on r
equirements for sloped or peaked ceilings.

IF YOUR SMOKE/CO ALARM SOUNDS
WHA
T TO DO IF CARBON MONOXIDE IS DETECTED
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alar
m sounds, you must not ignore it!
WHAT TO DO IF SMOKE IS DETECTED
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
i
mmediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the battery to quiet an unwanted alarm.
Removing the battery disables the Alarm so it cannot sense
s
moke. This will remove your protection. Instead, open a
window or fan the smoke away from the unit. The Alarm will
reset automatically.
• If the unit alarms get everyone out of the house immediately.
If the unit alarms and you are certain that the source of smoke is not a
f
ire—cooking smoke or an extremely dusty furnace, for example—open a
nearby window or
door and fan the smoke away from the unit. Use the
Silence Feature to silence the Alarm. This will silence the alarm, and
o
nce the smoke clears the unit will reset itself automatically.
WHAT TO DO IN CASE OF FIRE
•
Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
d
ressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly
.
Don’t open a hot door. Keep doors
a
nd windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
•
Meet at your planned meeting place outside your home,
a
nd do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
G
ive your address, then your name.
•
Never go back inside a burning building for any reason.
•
Contact your Fire Department for ideas on making your home safer.
A
larms have various limitations. See "General Limitations of
Smoke/CO Alarms" for details.
IF THE CO ALARM SOUNDS:
1. Operate the Test/Silence button.
2. Call your emer
gency services, fire department or 911. Write down
the number of your local emergency service here:
_____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window
. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your Smoke/CO Alarm remains
in its normal condition.
4. After following steps 1-3, if your Smoke/CO Alarm reactivates within
a 24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of
this equipment. If problems are identified during this inspection
have the equipment serviced immediately
. Note any combustion
equipment not inspected by the technician, and consult the
manufacturers’ instructions, or contact the manufacturers directly,
for more information about CO safety and this equipment. Make
sure that motor vehicles are not, and have not, been operating in
an attached garage or adjacent to the residence. Write down the
number of a qualified appliance technician her

LA
TCHING FEA
TURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the
“Smoke/Power” or “CO” Red LED will begin to flash On 2
seconds/Of
f 2 seconds. It will continue to flash or “latch” until you clear
it by testing the alarm.
This feature helps emergency responders, investigators, or service
technicians identify which unit(s) in your home were exposed to alarm
levels of smoke or carbon monoxide. This can help investigators
pinpoint the sour
ce of smoke or CO.
The Latching Alarm Indicator stays ON until you clear it, so it can alert
you to an alarm that occurred while you were away from home, even
though smoke or CO present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the "low battery
condition". When this occurs, the

for 2 seconds/Off for 2 seconds. This feature is designed to help you
identify which Alarm needs to have the battery replaced. Although, the

in greater intervals than one minute, sometimes up to several hours, until
the battery reaches a steady low battery level. This innovative feature
