Important Warning Statements  
1. Information About Carbon Monoxide  
WARNING: This product is intended for use in ordinary indoor  
locations of family living units. It is not designed to measure com-  
pliance w ith Occupational Safety and Health Administration  
(OSHA), commercial or industrial standards. It is not suitable for  
installation in hazardous locations as defined in the National  
Electric Code.  
Ge n e ra l Ca rb o n Mo n o xid e In fo rm a t io n  
Carbon monoxide is a colorless, odorless and tasteless poison gas that  
can be fatal when inhaled. CO inhibits the bloods capacity to carry oxy-  
gen.  
Periodically review this alarm manual and discuss your CO alarm emer-  
gency procedure with all the members of your family. Never ignore a CO  
alarm. A true alarm is an indication of potentially dangerous levels of  
CO. CO alarms are designed to alert you to the presence of CO before  
an emergency – before most people would experience symptoms of CO  
poisoning, giving you time to resolve the problem calmly.  
The installation of this device should not be used as a substitute  
for proper installation, use and maintenance of fuel burning  
appliances, including appropriate ventilation and exhaust sys-  
tems. It does not prevent CO from occurring, nor can it solve an  
existing CO problem.  
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. 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.  
WARNING: This device is designed to protect individuals from  
acute effects of carbon monoxide exposure. It may not fully safe-  
guard individuals w ith specific medical conditions. If in doubt,  
consult a medical practitioner.  
Individuals w ith medical problems may consider using w arning  
devices w hich provide audible and visual signals for carbon  
monoxide concentrations under 30 PPM.  
This carbon monoxide alarm requires a continuous supply of elec-  
trical pow er – it w ill not w ork w ithout pow er. Models w ithout  
battery backup w ill not operate during pow er failure.  
Sym p t o m s o f CO Po iso n in g  
The following common symptoms are related to CO poisoning and  
should be discussed with ALL members of the household.  
This alarm has not been investigated for carbon monoxide detec-  
tion below 70 PPM.  
Mild Exposure:  
Slight headache, nausea, vomiting, fatigue (often described as  
flu-like” symptoms).  
Medium Exposure:  
Severe throbbing headache, drowsiness, confusion, fast heart rate.

The following conditions can result in transient CO situations:  
Dangerous Levels:  
When someone is experiencing symptoms of CO poisoning and CO  
readings are generally above 100 PPM. Anytime someone is experiencing  
the symptoms of CO poisoning this should be treated as an emergency.  
See “What to do When the Alarm Sounds” (inside front cover).  
Excessive spillage or reverse venting of fuel-burning appliances caused  
by outdoor ambient conditions, such as, wind direction and/or veloci-  
ty, including high gusts of wind, heavy air in the vent pipes  
(cold/humid air with extended periods between cycles).  
High Levels:  
Generally above 100 PPM, with no one experiencing symptoms. This  
should be treated as an urgent situation. See “What to do When the  
Alarm Sounds” (inside front cover).  
• Negative pressure resulting from the use of exhaust fans.  
• Simultaneous operation of several fuel-burning appliances competing  
for limited internal air.  
Mid Levels:  
Generally between 50 PPM to 100 PPM. This should be cause for  
concern and should not be ignored or dismissed. See What to do  
When the Alarm Sounds” (inside front cover).  
Vent pipe connections vibrating loose from clothes dryers, furnaces, or  
water heaters.  
Low Levels:  
• Obstructions in, or unconventional, vent pipe designs which can  
amplify the above situations.  
Generally below 50 PPM. Kidde recommends you take action to  
eliminate the source of CO. See “What to do When the Alarm Sounds”  
(inside front cover).  
Extended operation of unvented fuel-burning devices (range, oven,  
fireplace, etc.).  
IMPORTANT: If the alarm sounds, it should be treated as a poten-  
tially serious condition. See “What to do When the Alarm Sounds”  
(inside front cover).  
Temperature inversions which can trap exhaust gases near the ground.  
Vehicle idling in an open or closed garage, or near a home.  
Po ssib le So u rce s o f Ca rb o n Mo n o xid e  
To be safe, know the possible sources of CO in your home. Keep fuel-  
burning appliances and their chimneys and vents in good working condi-  
tion. Learn the early symptoms of exposure, and if you suspect CO poi-  
soning, move outside to fresh air and get emergency help. Your first line  
of defense is an annual inspection and regular maintenance of your  
appliances. Contact a licensed contractor or call your local utility compa-  
ny for assistance.  
Inside your home, appliances used for heating and cooking are the most  
likely sources of CO. Vehicles running in attached garages can also  
produce dangerous levels of CO.  
CO can be produced when burning any fossil fuel, such as gasoline,  
propane, natural gas, oil and wood. It can be produced by any fuel-  
burning appliance that is malfunctioning, improperly installed, or not  
ventilated correctly, such as:

• Automobiles, furnaces, gas ranges/stoves, gas clothes dryers, water  
heaters, portable fuel burning space heaters and generators,  
fireplaces, wood-burning stoves and certain swimming pool heaters.  
CO alarms provide early warning of the presence of CO, usually before a  
healthy adult would experience symptoms. This early warning is possible,  
however, only if your CO alarm is located, installed and maintained as  
described in this guide.  
Blocked chimneys or flues, back drafts and changes in air pressure,  
corroded or disconnected vent pipes, loose or cracked furnace

to low levels may cause symptoms, as well as short-term exposures to  
high levels. This Kidde unit has a time-weighted alarm – the higher the  
level of CO present, the sooner the alarm will be triggered.  
Model KN-COPF-i  
This 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. If  
your unit has alarmed and youve 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, its crucial that the source of the CO is determined  
and that the appropriate repairs are made.

CO alarms have limitations. Like any other electronic device, CO alarms  
are not fool-proof. CO alarms have a limited operational life. You must  
test your CO alarm 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 unit replaced. This alarm will not  
monitor CO levels while in an error condition.  
CO alarms can only sense CO that reaches the units sensor. Its possible  
that CO may be present in other areas without reaching the alarm. The  
rate and ability by which CO reaches the alarm may be affected by:

Sounder  
• Doors or other obstructions.  
Fresh air from a vent, an open window or other source.  
IMPORTANT: Seven (7) years after the initial pow er up, this alarm  
w ill “beep” every 30 seconds and display "End" to indicate that it  
is time to replace the alarm. Replace the alarm immediately! It  
w ill not detect CO in this condition. See Maintenance Section for  
more information regarding End of Life Notification.  
• CO being present on one level of the home and not reaching a CO  
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 these reasons, we recommend you provide complete coverage by  
placing a CO alarm on every level of the home. Please carefully read all  
information in sections 2 and 3 on properly installing this CO alarm.  
To help identify the date to replace the alarm, a label has been affixed to  
the inside of the cover. Write the “replace bydate (seven years from  
power up) in a permanent marker on this label.  
CO alarms cannot be used to detect the presence of natural gas  
(methane), propane, butane, or other combustible fuels.  
Instruct children never to touch, unplug or otherwise interfere with the  
alarm. Warn children of the dangers of CO poisoning.

When an interconnected Kidde smoke alarm detects smoke, the Kidde  
CO alarm will sound a smoke/fire alarm pattern of three (3) long beeps,  
followed by one (1) second of silence. This cycle repeats as long as  
smoke signal persists to alert you of the condition. The word “Fire” will  
scroll across the digital display. If this happens, leave the premises imme-  
diately by your escape plan and call your local fire department.  
WARNING: This unit is not a smoke alarm and will not detect smoke or  
fire. It will only alarm for smoke/fire if it receives a signal from an inter-  
connected Kidde smoke alarm.

DO NOT USE THE ALARM IF THE LABEL HAS BEEN PUNCTURED!  
Maintenance Tips  
If interconnected to Kidde smoke alarms, pressing the Test/Reset button  
on the CO alarm will have no effect on the smoke alarms. The smoke  
alarms will not be tested and will not alarm. However, when pressing  
the Test button on an interconnected smoke alarm, the CO alarm will  
emit a Smoke/Fire audible and visual alarm pattern of 3 long beeps, 1  
second of silence, repeated. NOTE: You do not need to press the Test  
button to take a CO reading.  
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.  
• Never use detergents or solvents to clean the alarm. Chemicals can  
permanently damage or temporarily contaminate the sensor.

with a rechargeable battery to supply short term back-up during a  
power outage.  
• Avoid spraying air fresheners, hair spray, paint or other aerosols near  
the alarm.  
• Do not paint the unit. Paint will seal the vents and interfere with  
proper sensor operation.  
IMPORTANT: Constant exposures to high or low humidity may  
reduce the life of your battery and alarm.  
Move the CO alarm to a remote location, to prevent possible damage or  
contamination of the sensor, prior to performing any of the following:  
End of Life Notification  
Seven (7) years after unit is first powered, this alarm will beep” every  
30 seconds and display "End" to indicate that it is time to replace the  
alarm (see Alarm Removal section for instructions). By pressing the  
Test/Reset button the audible notification will be silenced for up to two  
days giving you time to replace the unit at a more convenient time. The  
display will alternate between the the CO ppm reading and "End" to  
remind you to replace the unit right away. This silence feature can only  
be used for a few days before it will no longer function and the beep  
cannot be silenced. The alarm will still monitor and alarm for CO during  
this period but all other functionality will be lost.  
• Staining or stripping floors or furniture, painting or wall-papering  
• Using aerosols or adhesives  
WARNING: Reinstall the CO alarm as soon as possible to assure continu-  
ous protection.  
The following is a list of substances that at high levels can damage the  
sensor or cause temporary readings that are not CO readings:  
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl  
acetate, hydrogen, hydrogen sulfide and sulfur dioxide.  
Once AC power has been removed from unit after reaching its end of  
service life, the battery will discharge itself to render the unit safe for  
disposal.  
• Also most aerosol sprays, alcohol based products, paint, thinner, sol-  
vent, adhesive, hair spray, aftershave, perfume, auto exhaust (cold  
start) and some cleaning agents.
