SMOKE & CARBON MONOXIDE ALARM
WITH SILENCE CONTROL

READ ALL INSTRUCTIONS

The smoke alarm uses an extremely small amount of a radioactive element in the ionization
chamber. Do not tamper with radioactive sealed source or try to repair the smoke alarm
yourself. Refer to instructions for repairs.

LIMITA TIONS AND FUNCTIONS

• This combination smoke/carbon monoxide (CO) alarm requires constant 120VAC power
to operate properly.

• THERE ARE TWO BASIC SMOKE ALARM TYPES - IONIZA TION AND PHOTOELECTRIC.
Ionization smoke alarms (such as this smoke alarm) are your best overall choice for
reliability and fast response time, since they quickly sense small "invisible" smoke
particles and will also sense larger "visible" smoke particles. Photoelectric smoke
alarms may respond more quickly in certain types of fires, for example - slow smoldering
fires with large "visible" smoke particles. ALL TYPES OF SMOKE ALARMS HAVE
LIMITATIONS. NO TYPE OF SMOKE ALARM CAN SENSE EVERY KIND OF FIRE OR
SMOKE EVERY TIME.

• SMOKE ALARMS can sound an alarm only when smoke reaches their sensors. Smoke
may not reach the smoke alarm QUICKLY ENOUGH to ensure safe escape. They do not
sense heat, flame or gas (propane).

• ALL alarms have limitations. This combination smoke/CO alarm is not foolproof and is
not warranted to protect lives or property. It is not a substitute for insurance.

• WARNING - SINCE A SMOKE OR CO ALARM WILL NOT WORK WITHOUT POWER, having an
alarm(s) that works from two completely different power sources, such as an AC direct wire
with battery backup can give you an extra measure of protection in case of an AC power failure
or a dead battery.

• CO ALARMS are designed to detect carbon monoxide gas from any source of combustion
that reaches their sensor. They are NOT designed to detect any other type of gas.

• USING A SMOKE ALARM IN A SMOKY AREA LIKE A KITCHEN, OR IN A HIGH HUMIDITY
AREA NEAR A SHOWER, CAN CAUSE FALSE ALARMS. DO NOT TURN OFF THE AC
POWER TO QUIET THE ALARM. A SMOKE ALARM WILL NOT HELP PROTECT YOU IF IT
IS NOT POWERED. Properly locate your alarm to avoid nuisance alarms.

• A SMOKE ALARM MAY NOT ALWAYS WARN YOU ABOUT FIRES CAUSED BY
CARELESSNESS AND SAFETY HAZARDS LIKE SMOKING IN BED, VIOLENT
EXPLOSIONS, ESCAPING GAS, IMPROPER STORAGE OF FLAMMABLE MATERIALS,
OVERLOADED ELECTRICAL CIRCUITS, CHILDREN PLAYING WITH MATCHES,
NATURAL CAUSES SUCH AS LIGHTNING, OR ARSON. FIRE PREVENTION IS YOUR
BEST SAFEGUARD.

• SMOKE ALARMS CANNOT DETECT FIRES IF THE SMOKE DOES NOT REACH THEM.
Smoke from fires may not reach the sensing chamber and set off the alarm. One unit
should be installed inside each bedroom or sleeping area.

• SMOKE ALARMS MAY NOT DETECT FIRE ON ANOTHER FLOOR OR AREA OF THE
HOME. Recommended minimum protection is at least one unit in every sleeping area
and every bedroom on every level of your home. Interconnected units may provide earlier
warning than stand-alone units since all units alarm when one detects smoke.

• ALARMS MAY NOT BE HEARD. The alarm horn in this unit meets or exceeds current
standards, but it may not be heard if: (1) the unit is located outside a closed or partially
closed door; (2) residents recently consumed alcohol or drugs; (3) the alarm is drowned
out by noise from stereos, TV's, air conditioners or other appliances or (4) if residents
are hearing impaired or sound sleepers.

• Because it is possible for the alarm to fail at any time, you must test the alarm weekly
and replace it every 5 years.

• SMOKE ALARMS ARE NOT TO BE USED WITH DETECTOR GUARDS UNLESS THE
COMBINATION HAS BEEN EVALUATED AND FOUND SUITABLE FOR THAT PURPOSE.

• CURRENT STUDIES HAVE SHOWN SMOKE ALARMS MA Y NOT A WAKEN ALL SLEEPING
INDIVIDUALS AND THAT IT IS THE RESPONSIBILITY OF INDIVIDUALS IN THE
HOUSEHOLD WHO ARE CAPABLE OF ASSISTING OTHERS TO PROVIDE ASSISTANCE
TO THOSE WHO MAY NOT BE AWAKENED BY THE ALARM SOUND OR TO THOSE
WHO MAY BE INCAPABLE OF SAFELY EVACUA TING THE AREA UNASSISTED.

IMPORTANT SAFETY INFORMATION

About this Alarm

This combination alarm has separate sensors to detect smoke and carbon monoxide (CO).
The smoke alarm has priority over the CO alarm.

The combination smoke/CO alarm is designed to be used in ordinary indoor locations of
single-family households only.

The sensitivity of both the smoke and CO sensors and the horn patterns for both warnings,
comply with UL standards.

This combination smoke/CO alarm can be used as a replacement for all UNIVERSAL
Smoke and CO Alarms without additional wiring. This allows the user to easily upgrade
from individual smoke or CO alarms to a combination unit.

WHAT YOU SHOULD KNOW ABOUT CARBON MONOXIDE (CO)

Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is
a cumulative poison. Even low levels of CO have been shown to cause brain and other vital
organ damage in unborn infants with no effect on the mother.

The following symptoms are related to CARBON MONOXIDE POISONING and should be
discussed with ALL members of the household:

MILD EXPOSURE

Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).

MEDIUM EXPOSURE

Severe throbbing headache, drowsiness, confusion, fast heart rate.

EXTREME EXPOSURE

Unconsciousness, convulsions, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware

they are not well, but they become so disoriented that they are unable to save themselves
by either exiting the building or calling for assistance. Young children and household pets
may be the first affected.

Your combination smoke/CO alarm is designed to detect the toxic CO fumes that result
from incomplete combustion, such as those emitted from appliances, furnaces, fireplaces
and auto exhaust.

This alarm will only indicate the presence of carbon monoxide gas surrounding its sensor.
Carbon monoxide gas may be present in other areas.

This product is intended for use in ordinary indoor locations of family living units. It is not
designed to measure compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards. Individuals with medical problems may consider
using warning devices which provide audible and visual warnings for carbon monoxide
concentrations under 30 PPM.

WHAT YOU SHOULD DO IF THE CO ALARM SOUNDS

Never disconnect a combination Smoke/CO alarm to silence an alarm. The alarm will
automatically sense when the level of CO in the air falls below the danger level. You should
stay outside the residence in fresh air until the alarm is silenced. When the alarm sounds,
do not stand too close to the alarm. The sound produced by the alarm is loud because it is
designed to awaken a person in an emergency. Prolonged exposure to the alarm at a close
distance may be harmful to your hearing.

Two self-adhesive labels have been provided with instructions indicating what to do if the
CO alarm sounds. Add the phone numbers of your emergency services provider and a
qualified technician to each label. Place one of the labels in a visible area next to the alarm
and place the other label near a source of fresh air which will be used as a gathering place
if the alarm sounds.

WHAT YOU SHOULD DO IF THE SMOKE ALARM SOUNDS

YOU MUST QUICKLY DO THE FOLLOWING:
If the smoke alarm sounds and you have not pushed the test button, it is a warning of a
dangerous situation.
Your immediate response is necessary . T o prep are for such occurrences, develop family
escape plans, discuss them with ALL household members and practice them regularly .
BASICS OF ESCAPE PLAN

o Make a floor plan indicating all doors and windows and at least two escape routes from each

room. Second story windows may need a rope or chain ladder.

o Have a family meeting and discuss your escape plan, showing everyone what to do in case of

fire.
o Determine a place outside your home where all of you can meet if a fire occurs.
o Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they

hear the sound.
o Identify children's bedrooms with red stickers placed in the upper left corner of the windows. They

are available from your local fire department.
o Practice a fire drill at least every six months. Practice allows you to test your plan before an

emergency. You may not be able to reach your children. It is import ant they know what to do!

WHA T TO DO WHEN THE SMOKE ALARM SOUNDS

o Leave immediately by your plan of escape. Every second counts, so don't waste time getting

dressed or picking up valuables.
o In leaving, don't open any inside door without first feeling its surface. If hot, or if you see smoke

seeping through cracks, don't open that door! Instead, use your alternate exit. If inside door is

cool, place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke

rush in.
o Stay close to the floor if air is smoky . Breathe shallowly through a cloth, wet if possible.
o Once outside, go to your selected meeting place and make sure everyone is there.
o Call the fire department from your neighbor's home – not from yours!
o Don't return to your home until fire officials say that it is all right to do so.

IMPORTANT CONSIDERATIONS

YOUR COMBINATION SMOKE/CO ALARM IS WARRANTED TO OPERATE
FOR FIVE YEARS.

NOTE: MANUFACTURER RECOMMENDS REPLACEMENT OF ALARM FIVE
YEARS AFTER DATE OF PURCHASE.

Activation of this device indicates the presence of carbon monoxide
(CO) which can kill you. If the CO alarm sounds:

1. Operate test/reset button;

2. Call your emergency services, fire department or 911;

3. Immediately move to fresh air - outdoors or by an open door/window. Do a head count

to check that all persons are accounted for. Do not reenter the premises nor move
away from the open door/window until the emergency services responders have arrived,
the premises have been aired out, and your alarm remains in its normal condition.

4. After following steps 1-3, if your 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 eq u ip m e nt 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
manufacturer(s) 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.

INSTALLING THE COMBINATION SMOKE/CO ALARM

FOR RESIDENTIAL USE

LOCATION

Before installing your combination smoke/CO alarm, it is important to choose the best
locations in your home. Placement can affect how well the alarm performs and how well
residents hear the alarm if it sounds. Statistics of the National Fire Protection Association
(NFPA) show that most of the fatal CO occurrences happen at night while people are
sleeping.

Early warning of CO is best achieved by the installation of CO alarms on all floors and
areas of the household.

RECOMMENDATIONS

– Put a CO alarm inside each bedroom where the occupant closes the door while sleeping.

Particulate smoke can be blocked by a closed door, but CO fumes are likely to get

through.
– A CO alarm should be installed between 5 and 20 feet from potential sources of CO in

any family living unit containing a fuel-burning appliance or fireplace or having an attached

garage.
– A combination smoke/CO alarm should be centrally located outside of each separate

sleeping area in the immediate vicinity of the bedrooms. Where bedrooms are separated

and audibility of the alarm to occupants within the bedroom area could be seriously

impaired, more than one unit could be needed.
– If a bedroom area hallway is more than 30 feet long, install a smoke alarm at each end.
– Alarms can alert you to a problem only after smoke or CO reach their sensors. Choose

locations free of obstructions, where the alarm will stay clean and protected from adverse

environmental conditions.
– Install a smoke or combination alarm on the basement ceiling at the bottom of the stairwell.
– Make sure the alarms can be easily heard from multiple locations throughout the home.
– This combination smoke/CO alarm makes it easy to provide both types of protection

throughout the home.
– This combination smoke/CO alarm is designed to be used in single-family homes. It

alone may not meet requirements for multiple-resident dwellings (apartment buildings,

boarding houses, hotels or motels).
– Some codes may require that smoke alarms be interconnected in new construction.
