Installation, Where to Install Your Alarm for complete information.
Step 2 - Install the 9 volt backup battery. To install the battery, open the back
cover and snap the battery connector onto the battery. You will hear the alarm
sound briefly to indicate the unit is receiving power. At power up, you will see the
the green power LED flash every 15 seconds until the unit is plugged into the
mains socket after which the power light will light continuously. It may take up to
30 seconds before remaining on continuously. Approximately 20 seconds the unit
receives power it will start sampling for CO. See “Normal Operating
Characteristics” for complete information on operating characteristics.
Place the battery into the battery compartment and replace the back cover.
Step 3 - Determine how you want to mount the alarm. Your CO alarm is
equipped to be mounted as a corded, a direct plug, or a table top unit. Refer to
Installation, How to Install your Alarm for complete instructions about how to
configure your alarm for installation.
Step 4 - Install the alarm. Plug the alarm into a standard un-switched 230 volt
AC electrical outlet in one of the alarm configurations listed in step 3. Wait 2 to 3
minutes after power up and make sure the power light is on.
Step 5 - Test the unit’s operation by pressing and releasing the Test/Reset
button. The unit will beep once to acknowledge the button was pressed. After a
short pause the unit will produce a quick beeping pattern for 8 seconds
While testing the alarm, have someone else check that the alarm can be heard
easily from the sleeping areas. The unit should be located where it can wake you
if it alarms at night.
Your alarm is now monitoring for the presence of CO gas.
For complete testing information, refer to How to Test Your CO Alarm” section.
Caution: Continuous exposure to the loud 85 decibel alarm at close range over
an extended period of time may cause hearing loss. We recommend that you
cover the front of the unit while testing the alarm with the palm of your hand.
We urge you to read this entire manual in the sequence it is presented.
IMPORTANT!
A small screwdriver or similar tool may be required to remove the back cover. The back
cover should be levered up from the centre recess at the bottom of the alarm. The cover is
designed this way to discourage the removal of batteries, or tampering, by young children.

This Kidde Carbon Monoxide (CO) Alarm is an important part of your family’s
home safety plan. As a new owner of a CO alarm, here are some basic facts
you should know for your protection and convenience
Carbon Monoxide
Carbon monoxide is invisible, odourless, tasteless, nonirritating, poisonous
gas that is completely undetectable to your senses. It is created when any fuel
is burned. When oxygen is limited during combustion, more CO is produced.
Serious problems can develop when combustion by-products are not properly
vented outside the house. That’s why it’s so important to your safety that
you have a CO alarm.
Please take the time to read this guide to familiarize yourself with the facts
about CO. Know how your new unit works, and what to do if it alarms. Find a
handy place to keep the guide so it will be readily available when you have a
question.
Thank you for making Kidde a part of your complete home safety program.
With proper installation and use, your new Kidde CO Alarm should provide
you with years of dependable service.

Kidde CO Alarm Unique Features
Test/Reset Button
This button has two functions. First, this is the button you press when
you test the unit weekly (see “How to test your CO alarm” section). It’s
also used when resetting the peak level memory.
Peak Level Button
If the CO sensor has detected a CO level of 50 PPM or higher, pressing
the Peak level button will produce 8 beeps to inform you of a CO incident. The memory must be cleared after each incident, see “The Peak
Level Memory Button” section for details
Sensors
The CO sensor is a highly sensitive, electrochemical sensor that is CO
specific to help avoid false alarms.
Sounder Alarm
This is the loud 85 decibel pulsing alarm that will sound to alert you to a
potential problem.
Pullout Transformer/Adapter
This unique Kidde alarm feature enables the alarm to be used as a
direct plug unit, a wall mounted unit or a tabletop unit.
9 Volt Backup Battery
This CO alarm is not battery operated. The 9 volt battery is to supply a
short-term backup power during a power cut. In the event of a power cut,
a fully charged 9 volt battery will continue operating the alarm for at least
20 hours.
When installing a fresh battery, use either an Energizer 522, Duracell MX1604
or MN1604, or for extended battery life an Ultralife lithium power cell model
U9VL. Any of these batteries can usually be purchased where you bought the
alarm or at your local hardware store.

What Carbon Monoxide Alarms Can and Cannot Do
This unit is designed to sense certain levels of CO from malfunctioning
furnaces, appliances, gas engines or other sources. This unit will provide early warning of the presence of carbon monoxide, usually before
a healthy adult would experience symptoms.
This early warning is possible only if your Kidde CO Alarm is located,
installed and maintained as described in this user’s guide.
This unit is designed to act as a continuous monitor; it is not designed
for use as a short-term testing device to perform a quick check for the
presence of CO.
CO alarms have a limited operational life. You must test your alarm
weekly, because it could fail to operate at any time. If it does fail to test
properly, or if its self-diagnostic test reveals a malfunction, immediately
have the unit replaced. See the back page for warranty information.
CO alarms can only sense CO that reaches the unit’s sensor. CO may
be present in other areas without reaching the alarm. Doors or other
obstructions may affect the rate at which CO reaches the unit. In addition, fresh air from a vent or open window or any other source may prevent CO from reaching the sensor. Please observe cautions in the
“Where to install your alarm” section.
CO could be present on one level of the home and not reach the alarm
installed on a different level. For example, CO in the basement may not
reach an alarm on the second level, near the bedrooms. For this reason, we recommend you provide complete coverage by placing a CO
alarm on every level of the home.
This unit is not a smoke alarm. It will not sense smoke or fire. For early
warning of fire you must install smoke alarms, even though a fire can
generate carbon monoxide.
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 company.

Mounting Configuration
LOCATION
Your Kidde CO Alarm should be mounted in or near bedrooms and living areas or wherever you suspect a CO exposure to be likely. It is recommended that you install a Kidde CO Alarm on each level of a multilevel home.
CAUTION: This alarm will only indicate the presence of CO at the sensor. Carbon monoxide may be present in other areas.
IMPORTANT: Improper location can affect the sensitive electronic components in this alarm. Please see the next section describing where
NOT to install this alarm.
Where Not to Install Your CO Alarm
To avoid causing damage to the unit, to provide optimum protection,
and to prevent unnecessary alarms, follow the directions below where
NOT to install this alarm:
It is not recommended that you install this CO alarm in garages or
kitchens. 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 CO. These levels are
higher when the engine is first started. Within hours of starting a vehicle
and backing it out of the garage, the level of remaining CO present can
activate the alarm and cause a nuisance alarm.
In the kitchen, some gas appliances can emit a short burst of CO upon
start-up. This is normal. If your CO alarm is mounted too close to these
appliances, it may alarm often and become a nuisance.
If you must install a Kidde CO Alarm near a cooking or heating appliance, install AT LEAST 1.8 metres (7 feet) away from the appliance.
Do not install the alarm in excessively dusty, dirty or greasy areas such
as boiler rooms. Dust, grease, or household chemicals can contaminate
or coat the alarm’s sensors, causing the alarm not to operate properly.
Do not install within 1.8 meters (7 feet ) of a steam/moisture source,
e.g., bathroom or kitchen sink.
Do not obstruct the vents on the alarm. Place the alarm where drapes,
furniture or other objects do not block the flow of air to the vents.
Do not install in dead air spaces, such as peaks of vaulted ceilings, a
gabled roof or within 15.2 cm (6”) of ceiling, where CO may not reach
the sensor in time to provide early warning.
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 anywhere
that is drafty. Rapid air circulation from fans or fresh air from outside
may cause the sensors to display an inaccurate reading.
2520-7201-00.qxd 2006.4.7 3:56 PM Page 7
Do not install this alarm to a switch- or dimmer-controlled outlet if possible
Do not install in areas where the temperature is colder than 4.4°C
(40°F) or hotter than 37.8°C (100°F). These areas include unconditioned crawl spaces, attics, porches and garages. Extreme temperatures will affect the sensitivity of the alarm.
Do not install this unit near deep cell large batteries. Large batteries
have emissions that can cause the alarm to perform at less than optimum performance.
Avoid the following:
• Excessive spillage or reverse venting of fuel burning appliances
caused by outdoor ambient conditions, such as:
1) Wind direction and/or velocity, including high gusts of wind.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
2) Negative pressure differential resulting from the use of exhaust
fans.
3) Simultaneous operation of several fuel burning appliances com-
peting for limited internal air.
4) Vent pipe connections vibrating loose from a clothes drier, fur-
nace or water heater.
5) Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
• Extended operation of unvented fuel burning devices (range, oven,
fireplace, etc.).
• Temperature inversions that can trap exhaust gasses near the
ground.
• Car idling in an open or closed attached garage, or near a home.
How to Install Your CO Alarm
Your Kidde CO Alarm with its removable adapter allows you to install
the alarm as a wall mounted unit, a direct plug unit, or as a table top
unit.
Refer to Where to Install Your CO Alarm for general guidelines.
Direct Plug Alarm

Wall Mounted Alarm
For a wall-mount, you will need to pull out the removable adapter and
power cord. This simple process is described on the following pages
.
Installation tips for power cord models:
The power cord option provides more flexibility in mounting locations
and allows the alarm to be easily installed at eye level.
Note: If you mount the alarm high on a wall, make sure it is at least
15.2 cm (6") from the ceiling. Any higher than this, it will be in “dead air
space” and CO may not reach the sensors.
To remove the adapter and install:
1. With the bottom of the unit facing you
(adapter at top), use a small screwdriver or similar tool to pry the back
cover up to release it.
2. Remove the back cover.
3. Next, place your thumb on the adapter
thumb release and pull the adapter
thumb release out slightly. Pull the
adapter out of the alarm with your other hand.
4. With the adapter removed, pull the power cord out of the cord
recess, remove the twist tie, and extend the power cord.
5. With the power cord extended, tuck the last few inches of the power
cord into the cord recess (See the illustration on page 4). Gently
pull the cord at the bottom of the cord recess until the cord
becomes taught and lays flat in cord recess.
6. Using the back cover, mark the location for the two mounting holes
on the wall.
7. If you are mounting the alarm in plaster board or
drywall, drill a 4.8 mm (3/16") hole into the wall
and insert the plastic anchors provided. Install the
two screws provided into the wall or wall anchors
until the screw head is approximately 3 mm (1/8")
from the wall.
8. Hook the keyhole in the back cover over the
screw head before or after replacing the back cover on the unit.
9. Plug the adapter into an unswitched wall socket.
Table Top Alarm
You can also use your Kidde CO Alarm as a table top unit. Simply follow the steps for removing adapter, then instead of mounting the alarm
to a wall, replace the back cover and stand the unit on a table, bedside stand, or chest of drawers.

Normal Operating Characteristics
When you first power up the unit, the alarm will sound briefly to let you
know the unit is receiving power and that the alarm circuit is functioning.
You should see the green power light blink every 15 seconds when the
unit is on battery only power and on continuously when powered by
AC.
Within 20 seconds, your CO alarm will start monitoring for CO and will
continue to do so as long as it receives power.
When the alarm is unplugged or loses power and you have a good 9
volt battery installed, the alarm will automatically switch to its battery
backup mode and you will notice the following:
• The green power light will switch from being lit continuously to blink
every 15 seconds.
• If CO is detected while on battery backup, the alarm will produce a
pattern is continuous quick beeps for as long as the CO is present
or until the battery is depleted.
Note: When AC power is restored, the alarm will automatically switch
back to normal operating mode.
Low Battery Warning
If the 9 volt battery is missing, or if the battery’s power is low, the alarm
will beep as well as the red and yellow lights blinking once every 15
seconds. If this happens, you need to replace the battery.
When you have a low battery installed, you will notice the following:
• Red light blinks in unison with the alarm beeping every 15 seconds.
• The yellow light will blink once every 15 seconds.
When battery is depleted and the unit is not receiving AC mains power:
• Red light blinks in unison with the alarm beeping every 30-45 seconds.
• The yellow light will flash approximately every 30-45 seconds.
• The green power light will not blink.
• Pressing the test button will not elicit any response.
The alarm will not detect CO if the battery is depleted. Replace the battery and plug the unit back into the AC outlet.
Constant exposures to high or low humidity may reduce battery life.
We recommend you replace your 9 volt battery at least every six
months.

How to Test Your CO Alarm
You should test the alarm once a week, following the directions listed
below. If at any time you test the alarm and it does not perform as
described, have it replaced immediately.
Turn to “How to know if your alarm is malfunctioning” section for a
description of the characteristics of a malfunctioning alarm and what
you should do if a malfunction occurs.
Observe the alarm weekly to make sure the green power light is lit continuously indicating normal operation.
If the green light is not on or the unit does not respond to pressing the
Test button, unplug the alarm for three minutes, and then plug it in
again. This will clear the alarm for restart. If the unit still does not
respond, your alarm may be malfunctioning.
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you should notice the following:
The unit will beep and the yellow LED will flash acknowledging the button was pressed and the self test has started. After a short pause, you
should then hear 8 seconds of quick beeps. It will then return to monitoring for CO.
Familiarize yourself and household members with the alarm pattern
described above a CO event.
While on AC power, in the event of a CO incident, the alarm pattern will
continue to repeat as long as CO is present.
NOTE: Pressing the Test/Reset button tests the functions of the alarm’s
internal components, circuitry and micro-computer.
YOU DO NOT NEED TO PRESS THE TEST BUTTON TO TAKE A CO
READING.
CO readings are taken every 15 seconds automatically.
How to Know If Your Alarm is Malfunctioning
Your alarm performs an internal self-diagnosis every 15 seconds to
make sure that it is functioning properly. The 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.
– The yellow LED will light continuously, and
– The unit does not respond to pressing the Test button.
Normal Operation

OR,
Malfunction Signal Group 2 - Microprocessor Failure
– The alarm will sound continuously,
– The yellow LED will light continuously
– The alarm cannot be shut off by pushing “Test/Reset” button, and,
– The unit is receiving sufficient power from the 230 volt outlet or
fresh battery.
Unplug the alarm immediately and return for warranty exchange (see
“Warranty” on back page).
What to do if you’re not sure...
PLEASE familiarize yourself with the malfunction alert, Do not confuse
these signals with an alarm. After reading the information above, if you
are still unsure whether your alarm is operating properly, call the Kidde
Freephone Customer Hotline at 0800 917 0722 to do a quick diagnostic
check of the alarm over the phone. The customer service representative will be able to assist you and answer your questions.
If your alarm sounder is beeping, and you are not sure if it is a CO
alarm or a malfunction alert, reset the alarm, open windows for ventilation and evacuate the premises immediately. Then call the Kidde
Freephone Customer Hotline at 0800 917 0722 for assistance.
Never ignore an alarm.
A true alarm is an indication of potentially dan-
gerous levels of CO.
How to Care for Your Alarm
To keep your alarm in good working order, you must follow these simple
steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
Unplug the alarm from the electrical outlet and use the soft brush
attachment of your vacuum cleaner.
• Instruct children never to touch, unplug, or otherwise interfere with the
alarm.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
• Avoid spraying air freshener, hair spray, paint or other aerosols near
the alarm.
• Do not paint the alarm. Paint will seal the vents and interfere with
proper sensor operation.
• Do not mount the alarm directly above or near a nappy pail.
2520-7201-00.qxd 2006.4.7 3:56 PM Page 12
Note: If you will be staining or stripping wood floors or furniture, painting, wall-papering, or using aerosols or adhesives for a do-it-yourself
project or hobby, before you begin:
Remove the alarm to a remote location to prevent possible damage to
or contamination of the sensor. You may wish to unplug the alarm and
store in a plastic bag during the project.
The following is a list of substances that at high levels can affect the
sensor and cause an alarm.
Methane, propane, iso-butane, ethylene, ethanol, alcohol, carbon
monoxide, iso-propanol, benzene, toluene, ethyl acetate, hydrogen,
hydrogen sulfide, sulfur dioxides.
Most aerosol sprays, alcohol based products, fresh paint, thinner, solvent, adhesive, hair spray, aftershave, perfume, auto exhaust (cold
start) and some cleaning agents.
The Peak Level Memory Button
This feature alerts you to possible CO events in your absence. If the
CO sensor has detected a CO level of 50 PPM or higher since it was
last reset, it will be recorded by the Peak Level Memory function. To
access the Peak Level Memory press the Peak button. If a reading of
50 PPM or higher has been recorded, the unit will beep 8 times. If
you’ve been away from home this feature allows you to check if there
was a CO incident during your absence. Push and hold the Peak button while pressing the Test button to reset the memory. It is also reset
when the power is removed.
Once the source is located, correcting the problem may be as easy as
opening a window, venting an appliance, backing a car out of the
garage a safe distance from living quarters, closing the garage door,
and letting the car warm up outside. It could be possible that a weather
condition caused the reading and the condition may or may not happen
again. DO NOT ignore an alarm. Refer to “Part 4- What to Do When
the Alarm Sounds for Carbon Monoxide” for more details.
To Reset the Peak Level Memory…
Step 1. Press and hold the peak level button.
Step 2. With the peak level button still pressed, press the test/reset but-
ton for two seconds and release.
The memory has now been cleared and the alarm will return to moni-
toring for CO within a few minutes.

2520-7201-00.qxd 2006.4.7 3:56 PM Page 13
The Effects of CO Exposure
When you breathe carbon monoxide, it enters your bloodstream
through your lungs and attaches to red blood cells. These red blood
cells, called haemoglobin, carry oxygen throughout your body. CO 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 CO
accumulates in your bloodstream, your body becomes starved for oxygen. The amount of CO in a person’s body can be measured by a simple blood test, called a “carboxyhaemoglobin level” test .
The early symptoms of CO poisoning are often mistaken for the flu –
headache, dizziness, weakness, nausea, vomiting, sleepiness, and
confusion. Breathing very high concentrations of CO can be lethal in
minutes.
Your Family at Risk for CO Poisoning
Carbon monoxide is the number one cause of poisoning deaths. While
anyone is susceptible, experts agree that unborn babies, small children, senior citizens and people with heart or respiratory problems are
especially vulnerable to CO and are at the greatest risk for death or
serious injury.
Where CO Comes From
Inside your home, fuel burning appliances used for heating and cooking
are the most likely sources of CO. Vehicles running in attached
garages can also produce dangerous levels of carbon monoxide.
A by-product of combustion, CO can be a potential problem from a
number of common sources such as – a running automobile, a furnace
or water heater leak or misuse of a fireplace, wood stove, charcoal grill,
a gas range and space heater leak or misuse, and running portable
generators where exhaust can enter the home.
When appliances are in good working condition and with proper ventilation, lethal CO gas is vented outdoors where it quickly disperses. Even
the slightest malfunction or misuse of any of the above sources can
lead to a build-up of CO in your home that can become deadly before
you even know it’s there.
You don’t have to have ancient appliances to have a CO problem.
14
What You Should Know Before the Alarm Sounds
2520-7201-00.qxd 2006.4.7 3:56 PM Page 14
Today’s more energy-efficient, airtight home designs can trap CO polluted air inside where it can quickly build to lethal levels.
What You Can do to Protect Your Family
To be safe, know the possible sources of CO in your home. Keep fuelburning appliances, their chimneys, and vents in good working condition. Learn the early symptoms of CO exposure. If you suspect CO
poisoning, move outside to fresh air and get emergency help. A blood
test can confirm that CO has caused the symptoms of CO poisoning.
Your first line of defence is an annual inspection and regular maintenance of your appliances. Contact a qualified Corgi installer or
Transco (British Gas) for assistance.
Remember, problems can begin after an inspection has been completed. CO can come from sources such as a crack in a furnace heat
exchanger, or a leak in a water heater vent or a bird’s nest blocking a
flue. Other sources of CO are nearly impossible to detect; even a
change in the air pressure outside can turn a normally safe situation
deadly. That’s why you need the 24-hour protection provided by a CO
alarm.
Home Safety Tips
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.
• 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 proper
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 fuel-burning 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 heater.
• Notice problems that could indicate improper appliance operation:
– Decreasing hot water supply
– Furnace unable to heat house or runs constantly
– Sooting, especially on appliances

members suffer from flu-like symptoms that don’t disappear but
improve when they leave home for extended periods of time.
Be Aware of the Warning Signs of Carbon Monoxide:
Indicators of Possible CO Leaks
• Streaks of carbon or soot around the service door of your fuelburning appliances.
• A yellow or orange flame may indicate a problem with natural gas
appliances.
• Excessive rusting on flue pipes or appliance jackets.
• Loose or missing furnace panel.
• Moisture collecting on the windows and walls of furnace rooms.
• Loose or disconnected vent/chimney, fireplace or appliance.
• Small amounts of water leaking from the base of the chimney,
vent or flue pipe.
• Rust on the portion of the vent pipe visible from outside your
home.
• The absence of a draft in your chimney (indicating blockage).
• Fallen soot from the fireplace chimney.
• Loose, damaged or discoloured bricks on your chimney.
Hidden Causes of CO Emission
• Internal appliance damage or malfunctioning components
• Improper burner adjustment
• Hidden blockage or damage in chimneys
Determine if anyone in the household is at high-risk for CO poisoning:
Many cases of reported CO 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 assistance.
You should take extra precautions to protect high-risk persons from
CO exposure because they may experience ill effects from CO at
levels that would not ordinarily affect a healthy adult. Be sure to
check infants or small children in the home for signs of possible CO
poisoning because they might have trouble explaining their symptoms. Infants and children are more susceptible to CO poisoning
than a healthy adult.

Pregnant women should be aware that their unborn fetus could be
harmed by exposure to CO, even when the mother suffers no ill effect.
Any pregnant woman who suspects she may have been exposed to
CO should immediately contact her physician.
What You Should Not Do...
• Never burn charcoal inside a home, garage, cabin, mobile home or
caravan.
• Never install, service, or convert fuel-burning appliances from one
type to another without proper knowledge, skills and tools.
• Never use a gas range, oven, or clothes dryer for heating.
• Never operate unvented gas-burning appliances, such as kerosene
or natural gas space heaters, in a closed room.
• Never operate gasoline-powered engines (like vehicles, motorcycles, lawn mowers, yard equipment, or power tools) in confined
areas such as garages or basements, even if an outside door or a
window is open.
• Never ignore a safety device when it shuts off an appliance.
• Never ignore a CO alarm.

Anyone in the household who is elderly, has anemia, heart disease,
respiratory problems, emphysema, or chronic bronchitis, is at a higher
risk of CO poisoning and health problems from exposure to CO. If anyone in the household is at high risk for CO poisoning, we urge you to
take extra precaution to prevent possible poisoning. You should consider a more sensitive alarm for your home safety. If the unit alarms or if
CO readings are shown on the digital display, remove the at-risk person
from the premises. Ventilate the area.
The high-risk person(s) should not re-enter the residence until the
source of the CO problem has been identified and corrected.

What to Do When the Alarm Sounds for Carbon Monoxide
Determine if anyone in the household is experiencing symptoms of CO poisoning. Many cases of reported CO 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 assistance. Also young
children and household pets may be the first affected. The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the
household.
When the CO alarm senses a dangerous level of CO, the unit
will emit a loud alarm pattern of short beeps. This pattern is
repeated until the CO concentration has dropped to normal
level.
Know how to respond to a CO emergency. Periodically review
this user’s guide and discuss it with all members of your family.
If the Alarm Sounds:
1) Operate test/reset button;
2) Call Transco (British Gas);
3) Immediately move to fresh air. Do a head count to check
that all persons are accounted for. Do not re-enter the
premises until British Gas responders have arrived, the
premises have been aired out, and your CO 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 Corgi
installer to examine and/or turn off your gas/oil fired appliances such as space heater, boiler, water heater, cooker
oven, clothes dryer or other source of combustion, such as
paraffin burning stove or heater or gas log fireplace. If your
car is idling in an attached garage, turn off the engine.
5) 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 manufacturer’s instructions, or contact
the manufacturer 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.
Treatment for CO Poisoning
Any person who is suspected to have CO poisoning should
leave the potentially dangerous environment, get fresh air
immediately and seek care from a physician. CO poisoning
can be determined by a simple blood test, called a “carboxyhaemoglobin” test. This test measures the amount of CO in
the bloodstream. For this test to be accurate, it must be done
immediately after CO exposure. Acute CO poisoning is usually treated by breathing in oxygen. When CO poisoning is
severe, (for example, when there is an altered state of consciousness), high-pressure oxygen therapy in a special
“hyperbaric chamber” may be used. A physician will make
this determination and administer treatment if necessary.
Call a Qualified Technician to Find and Repair the
Problem
Call a qualified service technician (such as a licensed heating contractor, utility service technician or fuel provider) to
inspect your home for possible sources of CO. Do not restart
these appliances until the problem is corrected. Request the
inspection and service for as soon as possible if not immediately.
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 charge if you purchased your
appliance from them. To know for sure, 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
alarm can only warn you of the presence of CO, it does not
prevent CO from occurring, nor can it solve an existing CO
problem.

Because you’ve provided ventilation by leaving your windows
and doors open, the CO 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 problem is determined
and appropriate repairs are made.
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 peak level function on
your Kidde CO Alarm helps the responders know how
severe the problem was before they arrived.
–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 back drafting – when air in a
chimney or flue is sucked into the home instead of venting
outside. The exact situation that created a negative air pressure inside the home (the cause of back drafting) is difficult
to recreate during an investigation for CO. Sometimes the
CO problem disappears when a door or window is opened.
Back drafting may or may not happen again.

How the Unit Determines When to Alarm
Your Kidde alarm uses advanced technology to monitor the environment in your home and warn you of certain levels of CO. An internal
microcomputer works together with the sensors inside the alarm to
determine the levels of CO in the air. The microcomputer is calibrated
to trigger the unit’s alarm before most people would experience any
symptoms of CO poisoning.
Replacement of the Alarm
This CO alarm has an "operational end of life" feature which will indicate when to replace the alarm.
Seven years after initial power-up, this unit will “chirp” every 30 seconds to indicate that it is time to replace the alarm. A label has been
affixed to the side of the alarm that has “Replace by” date printed on
it to aid in identifying the date of replacement.
REPLACE THE ALARM IMMEDIATELY! IT WILL NOT DETECT CO IN
THIS CONDITION.
