About This User’s Guide
Notice we call this booklet a “User’s Guide” and not an “Owner’s
Manual.” This is because our intention is for you to u s e this guide just
as you will be using your Kidde CO alarm. Keep the guide in a handy
location and refer to it when you have questions about your CO
a l a r m, its functions and features, or if you have questions about carbon monoxide. It will take about an hour of your time, but it’s well
worth it. Please read it in the sequence presented. Reading this guide
is the only way to learn how to use your CO alarm wisely and to
know how to react in the event of an alarm .
P a r t One
Your Kidde Carbon Monoxide Alarm , covers the unique feat u r es of your Kidde carbon monoxide alarm, how and where to install
it, as well as information on testing and maintaining your CO alarm .
P a r t Tw o
Carbon Monoxide - The Silent Killer, contains valuable inform ation about carbon monoxide (CO). From discovering the most common sources of CO in your home to recognizing the symptoms of CO
poisoning, this section provides tips and information that could help
p r otect your family from carbon monoxide poisoning.
P a rt Thre e
What You Should Know Before the Alarm Sounds, d e s c r i b e s
the effects of exposure to CO levels over time and when your Kidde
CO alarm will alarm. It also tells you how to determine who is at high
risk for CO poisoning.
P a rt Four
What to do When the Unit Alarm s , gives you step-by step information on how to respond to an alarm situation. Also covered is
whom to call for help if you think you have CO in your home.
P a r t Five
Technical Inform a t i o n , covers the technical specifications of your
Kidde CO alarm .
P a r t Six
F r equently Asked Questions, contains the most commonly asked
questions about our alarms. Part six was written by Kidde customer
service re p resentatives who handle thousands of calls per month, year
‘ r ound. This section provides you with answers and tips that will most
likely answer any questions you might have after reading this user’s
g u i d e .
I n t r o d u c t i o n
This Kidde carbon monoxide (CO) alarm is an important part of your
family’s home safety plan. So important, the U.S. Consumer Pro d u c t
Safety Commission (CPSC) recommends that every household should
have at least one carbon monoxide alarm. In fact, the CPSC chairm a n
has said that CO alarms are “as important to home safety as smoke
a l a rms.” Yet because CO alarms for the home haven’t been available
until recently, most people haven’t had much experience using them.
As a new owner of a CO alarm, there are some basic facts you
should know for your pro t e c t i o n and c o n v e n i e n c e .
Many people think that CO alarms operate like smoke alarms. And
in some basic ways, this is true. Like smoke alarms, CO alarms continuously monitor the air in your home and sound a loud alarm to
w a r n you of tro u b l e .
But, the similarities end here. The way you respond to a CO alarm
is quite diff e r ent than that of a smoke alarm. That’s because a house
f i re and a carbon monoxide problem are two distinctly diff e r ent situations. If your smoke alarm were to alarm, you would quickly be able
to judge the level of danger you were in (if any) with your five senses: you could see and smell the smoke, you could feel the heat, you
could see and even hear the fire burning. You could also readily see
if your smoke alarm were alarming in a non-emergency situation, say
if someone smoked up the kitchen with some seriously burnt toast.
Because your sense of sight, smell, hearing and touch give you so
much information, you could almost instantly judge what action to
take if you heard your smoke alarm .
But now, what about a CO alarm? Carbon monoxide (CO) is invisible, odorless, tasteless and non-irritating–completely undetectable to
your five senses. That’s why it’s so important to your safety that you
have a carbon monoxide alarm. But, how do you know what to do if
your unit alarms?
You have to l e a rn what to do, because your five senses won’t tell
you. That’s why this user’s guide is so important. Please take the
time to read this guide from cover to cover, to familiarize yourself
with the facts about carbon monoxide, how your new alarm works,
and what to do if it alarms. Then, find a handy place to keep the
guide so it will be readily available in the future when you have a
question. You might want to write down Kidde’s toll-free customer
service number and keep it with your other important phone numbers for the same re a s o n .
Thank you for making Kidde a part of your complete home safety
p rogram. With proper installation and use, your new Kidde CO
a l a rm should provide you with years of dependable service.

Step 1
D e t e r mine the best location for your CO alarm(s). Usually this is in or
near bedrooms. Refer to page 11 for complete inform a t i o n .
Step 2
Plug the CO alarm into a standard, unswitched 120 volt AC electric outlet. You will hear the alarm sound briefly to indicate the alarm is re c e i v ing power. Refer to page 13 for more details.
Step 3
The green Operate light will come on and stay on showing the CO
a l a r m is receiving power.
Step 4
Next, test the alarm’s operation by pressing and releasing the Te s t / R e s e t
button. The unit will beep quickly 4 times – followed by 5 seconds of
silence – followed by 4 quick beeps. This is also the alarm cycle in the
event of a CO problem. Familiarize yourself and household members
with this alarm pattern. The red Alarm light will come on when the
a l a r m sounds. For complete testing information, refer to page 15.
Step 5
While testing the CO alarm, have someone else check that the alarm
can be heard easily from the sleeping areas. The CO alarm should be
located where it can wake you if it alarms at night. See page 11 for
complete information on the best locations for your CO alarm.
Caution: Continuous exposure to the loud 85 decibel alarm at close
range over an extended period of time may cause hearing loss.
That’s it. Your Kidde CO alarm is now monitoring for the presence of
carbon monoxide.
We urge you to read this entire manual
in the sequence it is presented. But, if
you only read one part of this manual
i n i t i a l l y , read these two pages!
Listed below are five easy steps for setting up your Kidde CO alarm .

K i d d e ’ s Unique Feature s
Test/Reset Button
This button has two functions. First, this is the button you pre s s
when you test the unit weekly (see page 15 for further details).
Secondly, you press this button if the unit alarms and you want to
t u rn it off. This will re s e t the unit and it will then again start monitoring for CO. (If CO concentration is above 70 ppm, the alarm
will again sound within 6 minutes.)
Ve n t s
Air (and CO) enters into the alarm at the bottom vent and circ u l a t e s
t h r ough the sensing chamber. For proper air circulation, keep vents
f ree of dust, dirt or grease, (see “How to care for your CO alarm ”
page 17). Do not obstruct or block vents, (see “Where to install
your CO alarm” on page 11).
S e n s o r
The sensor is a highly sensitive, electrochemical sensor that is COspecific to help avoid false alarms. Tu rn to page 17 for more information on how to care for and protect the CO alarm .
Sounder Alarm
This is the loud 85 decibel pulsing alarm that will sound to alert you
to a potential problem. Alarm condition is 4 quick beeps – followed
by 5 seconds of silence – followed by 4 quick beeps, re p e a t .
C a u t i o n : Continuous exposure to this sound level at close range
over an extended period of time may cause hearing loss. We
recommend you cover the sounder with your finger while testing.
M o re on testing on page 15.
What Carbon Monoxide Alarms Can and Cannot Do
CO alarms are designed to sense unacceptable levels of CO fro m
malfunctioning furnaces, appliances, gas engines or other sources.
CO alarms provide early warning of the presence of carbon monoxide, usually before a healthy adult would experience symptoms.
This early warning is possible, however, only if your Kidde CO
a l a r m is located, installed and maintained as described in this user’s
g u i d e .
This CO alarm is designed to act as a c o n t i n u o u s m o n i t o r , it is not
designed for use as a short-term testing device to perf o rm a quick
check for the presence of CO.
CO alarms have limitations. Like any other electronic device, CO
a l a rms are not fool-pro o f .
CO alarms have a limited operational life. You must test your CO
a l a rm weekly, because it could fail to operate at any time. If your
CO alarm fails to test properly, or if its self-diagnostic test reveals a
malfunction, immediately have the alarm replaced. See page 34 for
warranty inform a t i o n .
CO alarms will not work without power. This CO alarm re q u i r es a
continuous supply of electric power.
CO alarms can only sense CO that reaches the CO alarm’s
s e n s o r . Carbon monoxide may be present in other areas without
reaching the alarm. The rate at which CO reaches the alarm may be
a ffected by doors or other obstructions. In addition, fresh air from a
vent or open window or any other source may prevent CO fro m
reaching the sensor. Please observe cautions on page
11, “Where to install your CO alarm . ”
CO could be present on one level of the home and not reach a CO
a l a rm installed on a diff e r ent level. For example, CO in
the basement may not reach a alarm on the second level, near the
b e d r ooms. For this reason, we recommend you provide complete
coverage by placing a CO alarm on every level of
the home.
CO alarms are not smoke alarms. CO alarms do not sense smoke or
f i re. For early warning of fire you must install smoke alarms, even
though carbon monoxide can be generated by a fire.
CO alarms should not be used to detect the presence of natural gas
(methane), propane, butane, or other combustible fuels.
CO alarms are not a substitute for property, disability, life or other
insurance of any kind. Appropriate insurance coverage is your
responsibility. Consult your insurance agent.

W h e r e to Install Your CO Alarm
Your Kidde CO alarm should be mounted in or near bedrooms and living areas. It is recommended that you install a Kidde CO alarm on each
level of a multi-level home. You may use the number and location of
smoke alarms installed in your home according to current building code
re q u i r ements as a guide to the location of your Kidde CO alarm ( s ) .
WHEN CHOOSING YOUR INSTA L L A TION LOCATIONS, MAKE
SURE YOU CAN HEAR THE ALARM FROM ALL SLEEPING
AREAS. IF YOU INSTALL ONLY ONE CARBON MONOXIDE
ALARM IN YOUR HOME, INSTALL THE ALARM NEAR BEDROOMS, NOT IN THE BASEMENT OR FURNACE ROOM.
Seven (7) years after initial power up, this unit will "chirp" every 30
seconds to indicate that it is time to replace the alarm. After seven
years the device may no longer detect carbon monoxide accurately
and should be replaced immediately. To help identify the date to
replace the unit, a label has been affixed to the side of the alarm .
Write the "Replace by" date (7 years from power up) in perm a n e n t
marker on the label.
CAUTION: This CO alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in other are a s .
I M P O R TA N T: I m p roper location can affect the sensitive electro n i c
components in this CO alarm. Please see the next section describing
w h e r e NOT to install this CO alarm .
If you must install a Kidde CO alarm near a cooking or heating applia n c e , install at least 15 feet away from the appliance.
Do not install in excessively dusty, dirty or greasy areas such as
kitchens, garages and furnace rooms. Dust, grease or household
chemicals can contaminate or coat the alarm’s sensor, causing the unit
not to operate pro p e r l y .
Do not obstruct the vents of the CO alarm. Place the CO alarm where
drapes, furn i t u re or other objects do not block the flow of air to the
v e n t s .
Do not install in dead air space, such as peaks of vaulted ceilings or
gabled roofs, where carbon monoxide may not reach the sensor in
time to provide early warn i n g .
Do not install in turbulent air from ceiling fans. Do not install near
doors and windows that open to the outside, near fresh air vents, or
a n y w h e re that is drafty. Rapid air circulation from fans or fresh air
f rom outside may affect the unit’s alarm response time.
Do not install this CO alarm in a switch- or dimmer- c o n t r olled outlet.
Do not install in areas where the temperature is colder than 40˚F
(4.4˚C) or hotter than 100˚F (37.8˚C). These areas include unconditioned crawl spaces, attics, porches and garages. Extreme temperature s
will affect the sensitivity of the CO alarm .
Do not install CO alarm near deep cell large batteries. Large batteries
have emissions that can cause the CO alarm to perf o r m at less than
optimal perf o rm a n c e .
The following conditions can result in transient CO situations:
Excessive spillage or reverse venting of fuel-burning appliances caused by:
• outdoor ambient conditions, such as wind direction and/or velocity,
including high gusts of wind, and insufficient draft in the vent pipes;
• negative pressure differential resulting from the use of exhaust fans;
• simultaneous operation of several fuel-burning appliances competing
for limited internal air;
• loose vent pipe connections from fuel-fired appliances;
• obstructions, or unconventional vent pipe designs that can amplify
the above situations;
• poorly designed or maintained chimneys and/or vents;
Extended operation of unvented fuel-burning devices (range, oven,
fireplace, etc.);
Temperature inversions that can trap exhaust gasses near the ground;
and a
Car idling in an open or closed attached garage, or near a home.
W h e r e N o t to Install Your CO Alarm
To avoid causing damage to the CO alarm, to provide optimum
p r otection, and to prevent unnecessary alarms, follow the dire c tions below where NOT to install this CO alarm :
It is not recommended that you install this CO alarm in garages,
kitchens or furnace rooms. Installation in these areas could lead to
nuisance alarms, may expose the sensor to substances that could
damage or contaminate it, or the alarm may not be heard by persons
in other areas of the home, especially if they are sleeping.
In the garage, vehicle exhaust can contain some carbon monoxide.
These levels are higher when the engine is first started. CO levels in a
garage may not be sufficient to activate the alarm immediately. Wi t h i n
hours of starting a vehicle and backing it out of the garage, the levels
p r esent over time can activate the alarm and become a nuisance.
In the kitchen and furnace room, some gas appliances can emit a
short burst of carbon monoxide upon startup. This is normal. If your
CO alarm is mounted too close to these appliances, it may alarm
often and become a nuisance.

N o r mal Operating Characteristics
When you first power up the alarm , the red alarm light will
come on and the alarm will sound briefly, then the green operate
light will come on. All this is to let you know the CO alarm is re c e i v ing power and that the alarm circuit is functioning.
Within a few minutes, your carbon monoxide alarm will start monitoring for CO and will continue to do so as long as it receives power.
Your Kidde CO alarm will now sample the air every fifteen seconds
and alert you if it senses dangerous CO levels.
For more information about the effects of CO exposure at
d i ff e r ent levels over time, refer to the chart on 23 as well as the information on pages 24-26.
When the CO alarm is unplugged or loses power, a fading
a l a rm will sound briefly to alert you that it has been disconnected
f rom its power source. For example, this fading alarm will sound in
the event of a power outage. A brief alarm will also sound to alert
you when the power is re s t o re d .

How to Know If Your Alarm is Malfunctioning
Your CO alarm perf o rms an internal self-diagnosis every fifteen seconds to make sure that it is functioning properly. The CO alarm is
designed to alert you in the unusual event of a malfunction.
If the alarm malfunctions.
In the rare event that your alarm malfunctions, it will alert you with
one of these signal groups (depending upon the type of malfunction
that occurs):
Malfunction Signal Group 1 - Component Failure
– An intermittent “chirping” alarm will sound every 30 seconds.
O R ,
Malfunction Signal Group 2 - Micro p r ocessor Failure
– The alarm will sound continuously, and
– The alarm cannot be shut off by pushing the “Test/Reset” button
Unplug the CO alarm immediately and re t u rn for warranty exchange
(see “Warranty” on page 34).
What to do if you’re not sure . . .
PLEASE familiarize yourself with the malfunction alert, and do not confuse these signals with an alarm. After reading the information above, if
you are still unsure whether your CO alarm is operating properly, call
the Kidde toll-free consumer hotline at 1 800-581-6742 to do a quick
diagnostic check of the alarm over the phone. The customer service
re p r esentative will be able to assist you and answer your
q u e s t i o n s .
If your CO alarm sounder is beeping, and you are not sure if it is a CO
a l a r m or a malfunction alert, reset the alarm, open windows for ventilation, turn off fuel-burning appliances (like kerosene or oil heaters, furnaces, gas ranges, wood-burning stoves, water heaters, or other fossilfuel burning appliances). For furnaces, you can simply turn down the
t h e rmostat to its lowest setting. Open windows and doors for ventilation. Then call the Kidde toll-free consumer hotline at 1 800-581-6742
for assistance.
B e f o r e you call a qualified technician (such as a licensed heating cont r a c t o r , utility service technician, chimney sweep or fuel provider) to
check your residence for CO, remember that you will probably be
c h a r ged for a service call. Kidde customer service operators are available to answer your questions and assist you in non-emergency situations at no charge.
Never ignore a CO unit’s alarm. A true alarm is an indication of potentially dangerous levels of carbon monoxide. CO alarms are designed to
alert you to the presence of carbon monoxide before an emerg e n c y ,
b e f o re most people would experience symptoms of carbon monoxide
poisoning, giving you time to resolve the problem calmly.
P a r t One – Your Kidde CO Alarm
Testing the Electro n i c s
You should test the alarm once a week, following the dire c t i o n s
listed below. If at any time you test the alarm and it does not perf o rm as described below, have it replaced immediately. Tu rn to page
16 “How to know if your alarm is malfunctioning” for a description
of the characteristics of a malfunctioning alarm and what you should
do if a malfunction occurs.
Observe the CO alarm regularly to make sure the green operate light
is on, indicating normal operation.
If the green operate light is not on, unplug the CO alarm for thre e
minutes, then plug in again. This will clear the alarm for restart.
If the green operate light does not come back on, your CO alarm
may be malfunctioning.
To test the CO alarm , p r ess and release the Test/Reset button,
within 15 seconds if the CO alarm is operating properly, you will
hear 4 quick beeps – followed by 5 seconds of silence – followed by
4 quick beeps. Notice the Red Alarm Light flashes when the unit
a l a r ms.
When you test the CO alarm, we advise you to place your finger
over the sounder opening in the front of the CO alarm.
Within a minute, the alarm will then re t u rn to monitoring for carbon
m o n o x i d e .
NOTE: P r essing the Test/Reset button tests the functions of the
CO alarm’s internal components, circuitry and micro - c o m p u t e r.
YOU DO NOT NEED TO PRESS THE TEST BUTTON TO TAKE
A CO READING.

What is Carbon Monoxide?
Carbon monoxide (CO) is an odorless, colorless, poisonous gas cre a ted when any fuel is burned – gasoline, propane, natural gas, oil,
wood, coal, and even tobacco. When combustion air is limited, more
CO is produced. Serious problems can develop when combustion byp r oducts are not properly vented outside the house.
You’ve probably heard about carbon monoxide poisoning in the
news recently. It’s a problem receiving more attention because gro u p s
like the American Lung Association and the Consumer Product Safety
Commission have made it a priority to warn the public about the
dangers of this deadly household poison.
What are the Effects of CO Exposure ?
When you breathe carbon monoxide, it enters your bloodstre a m
t h r ough your lungs and attaches to red blood cells. These red blood
cells, called hemoglobin, carry oxygen throughout your body. Carbon
monoxide molecules attach to the red blood cells 200 times faster
than oxygen, preventing the flow of oxygen to your heart, brain and
vital organs. As carbon monoxide accumulates in your bloodstre a m ,
your body becomes starved for oxygen. The amount of carbon
monoxide in a person’s body can be measured by a simple blood
test, called a “carboxyhemoglobin level” test .
The early symptoms of carbon monoxide poisoning are often mistaken for the flu – headache, dizziness, weakness, nausea, vomiting,
sleepiness, and confusion.
B r eathing very high concentrations of carbon monoxide can be lethal
in minutes. Breathing low concentrations over time is dangerous, too.
Long term exposure to low levels could cause permanent heart and
brain damage.
Could Your Family be at Risk for CO Poisoning?
Carbon monoxide is the number one cause of poisoning deaths in
the United States. According to the Mayo Clinic, at least 10,000
Americans are affected by CO poisoning each year.
While anyone is susceptible, experts agree that unborn babies, small
c h i l d ren, senior citizens and people with heart or respiratory pro blems are especially vulnerable to CO and are at the greatest risk for
death or serious injury.

How to Care for Your CO Alarm
To keep your CO alarm in good working ord e r, you must follow
these simple steps:
• T est the CO alarm once a week by pressing the Test/Reset button
•Vacuum the alarm cover once a month to remove accumulated
dust. Use the soft brush attachment of your vacuum cleaner, and
unplug the CO alarm from the electrical outlet before vacuuming.
•Instruct children never to touch, unplug or otherwise interf e r e
with the unit. Wa rn children of the dangers of CO poisoning.
•Never use detergents or solvents to clean the CO alarm. Chemicals
can permanently damage or temporarily contaminate the sensor.
•Avoid spraying air fresheners, hair spray, paint or other aerosols
near the CO alarm .
•Do not paint the CO alarm. Paint will seal the vents and interf e r e
with proper sensor operation.
•Do not mount the CO alarm directly above or near a diaper pail,
as high amounts of methane gas can cause temporary re a d i n g s
on the digital display.
Note: If you will be staining or stripping wood floors or furn i t u re ,
painting, wall-papering, or using aerosols or adhesives for a do-it-yourself project or hobby, b e f o re you begin: Remove the CO alarm to a
remote location to prevent possible damage to or contamination
of the sensor. You may wish to unplug the CO alarm and store it in a
plastic bag during the pro j e c t .
The following is a list of substances which, at high levels, can affect the
sensor and may cause a nuisance alarm that is not a carbon monoxide
a l a r m .
Methane, propane, iso-butane, ethylene, ethanol, alcohol,
i s o - p ropanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, sulfur dioxides.
Also most aerosol sprays, alcohol based products, paints, thinners, solvents, adhesives, hair sprays, after shaves, perf u m e s ,
auto exhaust (cold start) and some cleaning agents.

What You Can Do...
•Buy only appliances approved by a nationally recognized
testing laboratory.
•Choose fuel-burning appliances that can be vented to the
outdoors, whenever possible.
•Make sure appliances are installed according to manufacturer’s
instructions and local building codes. Most appliances should
be installed by professionals and should be inspected by the
p r oper authority after installation.
•Have the heating system, vents, chimney and flue inspected
and cleaned by a qualified technician every year.
•Follow manufacturer’s directions for safe operation of all
f u e l - b u r ning appliances.
•Examine vents and chimneys regularly for improper connections,
visible rust or stains.
•Open a window when a fireplace or wood-burning stove is in
use, and provide adequate outdoor air for furnace and water
h e a t e r .
•Notice problems that could indicate improper appliance operation:
– Decreasing hot water supply
– Furnace unable to heat house or runs constantly
– Sooting, especially on appliances
– Unfamiliar or burning odor
– Yellow or orange flame
•Be aware of the symptoms of carbon monoxide poisoning:
– headaches, dizziness, weakness, sleepiness, nausea, vomiting,
confusion and disorientation.
•Recognize that CO poisoning may be the cause when family
members suffer from flu-like symptoms that don’t disappear but
i m p r ove when they leave home for extended periods of time.
W h e r e Does CO Come Fro m ?
Inside your home, appliances used for heating and cooking are the
most likely sources of carbon monoxide. Vehicles running in
attached garages can also produce dangerous levels of carbon
m o n o x i d e .
A by-product of combustion, carbon monoxide can be a potential
p r oblem from a number of common sources – automobiles,
f u rnaces, water heaters, fireplaces, wood stoves, charcoal grills, gas
ranges, space heaters and portable generators.
When these appliances are in good working condition with pro p e r
ventilation, lethal carbon monoxide gas is vented outdoors where it
quickly disperses. But even the slightest malfunction or misuse of
any of these sources can lead to a build-up of carbon monoxide in
your home that can become deadly before you’d even know it’s
t h e r e .
And you don’t have to have ancient appliances to have a pro b l e m .
Today’s more energ y - e fficient, airtight home designs can trap CO-polluted air inside where it can quickly build to lethal levels.
What Can You do to Protect Your Family?
To be safe, know the possible sources of CO in your home. Keep
f u e l - b u r ning appliances and their chimneys and vents in good working condition. Learn the early symptoms of exposure, and if you
suspect carbon monoxide poisoning, move outside to fresh air and
get emergency help. A blood test can confirm that CO caused the
p r o b l e m .
Your first line of defense is an annual inspection and regular maintenance of your appliances. Contact a licensed contractor or call your
local utility company for assistance.
But re m e m b e r , problems can begin after an inspection is over, like a
crack in a furnace heat exchanger, or a leak in a water heater vent or
a bird’s nest blocking a flue. That’s why you need the 24-hour protection provided by a CO alarm.

P a r t Three – What You Should Know
B e f o r e the Alarms Sounds
D e t e rmi ne if anyone in the household is at high risk
for CO poisoning:
Many cases of reported carbon monoxide poisoning indicate that while
victims are aware they are not well, they become so disoriented they are
unable to save themselves by either exiting the building or calling for
a s s i s t a n c e .
You should take extra precautions to protect high risk persons f ro m
CO exposure because they may experience ill effects from carbon monoxide at levels that would not ordinarily affect a healthy adult.
A re there any infants or small children in the home? Be sure to check
them for signs of possible CO poisoning because they might have tro u ble explaining their symptoms. Infants and children are more susceptible
to CO poisoning than a healthy adult.
P r egnant women should be aware that their unborn fetus could be
h a rmed by exposure to carbon monoxide, even when the mother suff e r s
no ill effect herself. Any pregnant woman who suspects she may have
been exposed to carbon monoxide should immediately contact her
p h y s i c i a n .
Is there anyone in the household who is elderly, or who has anemia,
heart disease or respiratory problems, emphysema or chronic bro n c h i t i s ?
These individuals are at higher risk for CO poisoning and for health
p roblems from exposure to low levels of carbon monoxide.
If anyone in the household is at high risk for CO poisoning, we urge you
to take extra precautions to prevent possible poisoning. If the unit
a l a rms , remove the at-risk person from the premises, if possible. Ve n t i l a t e
the area. The high-risk person(s) should not re-enter the residence until
the source of the CO problem has been identified and corre c t e d .

Treatment for CO Poisoning
Any person who is suspected to have carbon monoxide poisoning
should leave the potentially dangerous environment, get fresh air
immediately and seek care from a physician. CO poisoning can be
d e t e rmined by a simple blood test, called a “carboxyhemoglobin”
test. This test measures the amount of carbon monoxide in the
b l o o d s t ream. For this test to be accurate, it must be done immediately after CO exposure. Acute CO poisoning is usually treated by
b reathing in oxygen. When CO poisoning is severe, (for example,
when there is an altered state of consciousness), high pre s s u r e oxygen
therapy in a special “hyperbaric chamber” may be used. A physician
will make this determination and administer treatment if necessary.
Calling a Qualified Technician to Find and Repair
the Pro b l e m
If you call a qualified service technician (such as a licensed heating
c o n t r a c t o r, utility service technician, chimney sweep or fuel pro v i d e r )
to inspect your home for possible sources of CO, you will want to
tell them which appliances (if any) were operating before the alarm
sounded. Do not restart these appliances until the problem is corrected. Request service for as soon as possible, like TO D AY.
Please be aware that some service technicians may charge a fee to
inspect your home, even if the source of CO is not found. You may
wish to find out if you will be charged for the service and the
amount of the fee before you request service. Some public utilities
do not charge for inspection. Some service technicians do not
c h a r ge if you purchased your appliance from them. To know for
s u re, you need to ask before the technician comes to your home.
Repair work or replacement of appliances may be necessary to fix
the problem that is creating the CO in your home. Remember, a CO
a l a r m can only warn you of the presence of CO, it does not pre v e n t
CO from occurring, nor can it solve an existing CO pro b l e m .
Because you’ve provided ventilation by leaving your windows and
doors open, the CO buildup may have dissipated by the time help
responds. Although your problem may appear to be temporarily
solved, it’s crucial that the source of the CO is determined and
a p p r opriate repairs are made.

P a r t Four – What to do When the
A l a r m Sounds
Sometimes it’s Difficult to Find the Source of
CO in a Home
It can be difficult for responders to locate the source(s) of CO if:
•The house was ventilated before they arrived and the fresh air
caused the CO to dissipate.
•The CO problem was caused by a source that fluctuates on
and off, sometimes creating CO and sometimes not. Such a
situation makes it nearly impossible to pinpoint the source of
CO in a short period of time.
•The cause of CO problem was backdrafting – when air in
a chimney or flue is sucked into the home instead of venting
outside. The exact situation that created a negative air pre s s u r e
inside the home (the cause of backdrafting) is difficult to re c reate
during an investigation for CO. Sometimes the CO problem
disappears when a door or window is opened. Backdrafting may
or may not happen again.

P a r t Six – Frequently Asked Questions
Q. How many alarms do I need in my house? How much
s q u a r e footage will one CO alarm cover?
A. We recommend you place alarms near the sleeping area(s). If
you have a multi-level home, you should place a CO alarm on each
level of the home. A good rule of thumb for the number and placement of CO alarms for your particular home is to place CO alarm s
near smoke alarms that have been installed to meet current building
code re q u i r e m e n t s .
Generally, one CO alarm can be adequate for 1,200 to 1,500 square
feet of living space. The most important determination for the number of alarms needed is whether an alarm can be heard in all sleeping are a s .
Q. What is the lowest level at which the CO alarm will sound?
A. The lowest level of carbon monoxide at which the alarm will
sound is 45 ppm. The CO alarm must be exposed continuously to
this level for at least three hours.
Q. Can you explain what “time-weighted alarm” means?
A. Because carbon monoxide is a cumulative poison, two factors
d e t e rmine how the body is affected by CO: the level of exposure
and the length of exposure. For example, being continuously
exposed to low levels of carbon monoxide for many hours can be
as dangerous as being exposed to higher levels of CO for a short
period of time.
The microchip inside your Kidde CO alarm monitors the air for the
p resence of carbon monoxide and computes the levels and length
of exposure, alarming when you should be concerned about CO
e x p o s u re .
For more information about the alarm, see page 29.
Q. Do I have to press the test button to get a CO alarm ?
A. No. If it detects a dangerous level of CO it will alarm automatically. To test the internal components and circuitry of your CO alarm ,
p ress the Test/Reset button.
P a r t Five – Technical Inform a t i o n
How the CO alarm determines when to alarm
Your Kidde CO alarm uses advanced technology to monitor the
e n v i r onment in your home and warn you of unacceptable levels of
carbon monoxide. An internal microcomputer works together with
the carbon monoxide sensor inside the alarm to determine the levels of carbon monoxide in the air and to calculate the rate that CO
would be absorbed into the human body.
The microcomputer is calibrated to trigger the alarm before most
people would experience any symptoms of carbon monoxide poisoning. Because carbon monoxide is a cumulative poison, longt e r m exposures to low levels can cause symptoms, as well as
s h o r t - t e rm exposures to high levels. Your Kidde CO alarm has a
time weighted alarm, so the higher the level of carbon monoxide
p r esent, the sooner the alarm will be triggered.
This CO alarm meets response time re q u i r ements as follows:
At 70 ppm, the unit must alarm within 60-240 minutes.
At 150 ppm, the unit must alarm within 10-50 minutes.
At 400 ppm, the unit must alarm within 4-15 minutes.
WARNING: This product is intended for use in ordinary indoor
residentual areas. It is not designed to measure compliance with
c o m m e r cial and industrial standards. This device is designed to

conditions. If in doubt, consult a medical practitioner.
Individuals with medical problems may consider using warn i n g
devices, which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm.

P a r t Six – Frequently Asked Questions
Q. I use the CO alarm in a vacation home that isn’t always
occupied and can have temperature extremes when no one is
t h e r e (no heat or no air conditioning). Will that hurt the CO
a l a rm? Should I leave it plugged in all the time?
A. We recommend that your CO alarm not be installed in are a s
w h e re temperatures fall below 40˚F (4.4˚C) or rise above 100˚F
( 3 7 . 8 ˚ C ) . Your CO alarm was designed to be constantly plugged in
for maximum perf o r m a n c e .
Q. I plugged in the CO alarm at my house (my parents’, my
neighbors’, etc.) and the alarm hasn’t sounded. Does that
mean everything is OK? (I’m thinking I can re t u rn the CO
a l a rm since everything checks out OK.)
A. This CO alarm is designed to act as a c o n t i n u o u s m o n i t o r , it is not
designed for use as a short-term testing device to perf o rm a quick
check for the presence of CO.
R e m e m b e r , a carbon monoxide problem can occur at any time, even
after a professional inspection has determined that everything is in
p r oper working ord e r. Examples of problems that can develop are a
crack in a furnace heat exchanger, a leak in a water heater vent, or a
b i rd’s nest blocking a flue.
That’s why you need the 24-hour protection provided by a CO
a l a rm.
P a r t Six – Frequently Asked Questions
Q. What happens if the power goes out?
A. If the power goes out, your alarm will sound a fading alarm to alert
you that power has been disconnected. When the power is re s t o re d ,
the CO alarm will automatically reset and will sound a brief alarm to
indicate it is receiving power.
In the event of a power outage, it is important to remember never to
use alternative sources of heat indoors such as charcoal, a gas oven or
unvented space heaters. These heat sources can cause extremely dang e r ous amounts of carbon monoxide.
Q. My unit has never alarmed. Is it really working?
A. If the green operate light is always on and the alarm operates as
described on page 15 when you test it, your CO alarm is constantly
monitoring for the presence of CO.
Q. You warranty the alarm for five years. How will I know
when it doesn’t work anymore and I need to buy a new one?
A. In any event of malfunction, your alarm should alert you with malfunction signals. These signals are described in detail on page 16.
Q. I called in someone to inspect my home for CO after my unit
a l a r med, and he couldn’t find anything wrong. Why? Does that mean
this alarm “false alarm e d ” ?
A. No. Please read the information explaining why a CO problem can
be difficult to diagnose on page 27. Also, please read the inform a t i o n
on page 16 to make sure you experienced an alarm and not a malfunction alert.
Q. How much electricity does it take to run the CO alarm ?
A. The CO alarm uses less than one watt of electricity. A typical night
light uses four watts.
Q. Will the CO alarm last longer if I unplug it during the summer months and only use it during the winter?
A. No. Some components of the CO alarm can deteriorate over time if
not used regularly. We recommend the CO alarm be plugged in continuously for maximum alarm life.
