What to do When the Alarm Sounds!  
Welcome  
Note: Many times throughout this User’s Guide, we will refer to  
Carbon Monoxide as “CO”.  
Carbon Monoxide Alarm Procedure  
This Kidde carbon monoxide (CO) alarm is an important part of your  
family’s home safety plan. This alarm has been designed and tested to  
detect CO buildup in a residential environment. Your alarm is for use  
specifically in the home. As an owner of a CO alarm, there are some  
basic facts you should know about for your protection.  
WARNING: Activation of the CO  
Alarm indicates the presence of Carbon  
Monoxide (CO) which can kill you.  
1) Operate the Test/Reset button;  
2) Call your emergency services (Fire Department or 911);  
PHONE NUMBER:  
Many people think that CO alarms operate like smoke alarms. Like  
smoke alarms, CO alarms monitor the air in your home and sound a  
loud alarm to warn you of trouble. The way you respond to a CO alarm  
is quite different than a smoke alarm. That’s because a house fire and a  
CO problem are two distinctly different situations. If your smoke alarm  
were to alarm, you would quickly be able to judge the level of danger  
you were in with your senses. You can see and smell the smoke, feel the  
heat, see, and possibly hear the fire burning. You can also readily see  
if your smoke alarm is alarming in a non-emergency situation. Because  
your sense of sight, smell, hearing and touch give you information, you  
can almost instantly judge what action to take if you hear your smoke  
alarm.  
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 the alarm reactivates within a 24  
hour period, repeat steps 1-3 and call a qualified appliance  
technician to investigate sources of CO from fuel burning  
equipment and appliances, and to inspect for proper operation  
of equipment.  
CO is an invisible, odorless, tasteless and non-irritating gas – completely  
undetectable to your senses. That’s why it is important to your safety  
that you have a CO alarm.

Important Warning Statements  
IMPORTANT: This carbon monoxide alarm is designed to detect  
carbon monoxide from ANY source of combustion. It is NOT  
designed to detect smoke, fire, or any other gas.  
If problems are identified during this inspection, have the equip-  
ment serviced immediately. Note any combustion equipment not  
inspected by the technician and consult the manufacturer’s instruc-  
tions, or contact the manufacturer’s directly for more information  
about CO safety and the equipment. Make sure that motor vehicles  
are not, or have not been, operating in a garage attached or adja-  
cent to the residence.  
WARNING: Carbon monoxide alarms are not smoke alarms. This  
carbon monoxide alarm is not a substitute for installing and  
maintaining an appropriate number of smoke alarms in your  
home.  
Never restart the source of a CO problem until it has been  
corrected. Never ignore the sound of the alarm!  
This carbon monoxide alarm will not sense smoke, fire, or any  
poisonous gas other than carbon monoxide even though carbon  
monoxide can be generated by fire. For this reason you must  
install smoke alarms to provide early warning of fire and to pro-  
tect you and your family from fire and its related hazards.  
If the alarm is sounding, pressing the test/reset button will  
terminate the alarm. If the CO condition that caused the alert  
in the first place continues, the alarm will reactivate. If the  
unit alarms again within six minutes, it is sensing high levels  
of CO which can quickly become a dangerous situation.  
CAUTION: This alarm will only indicate the presence of carbon  
monoxide at the sensor. Carbon monoxide may be present in  
other areas.

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  
compliance with 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.  
General Carbon Monoxide Information  
Carbon monoxide is a colorless, odorless and tasteless poison gas that  
can be fatal when inhaled. CO inhibits the blood’s capacity to carry  
oxygen.  
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 and  
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 with specific medical conditions. If in doubt,  
consult a medical practitioner.  
Individuals with medical problems may consider using warning  
devices which provide audible and visual signals for carbon mon-  
oxide concentrations under 30 PPM.  
This carbon monoxide alarm requires a continuous supply of elec-  
trical power – it will not work without power. Models without  
battery backup will not operate during power failure.  
Symptoms of CO Poisoning  
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).  
Contents of This User’s Guide  
Medium Exposure:  
Severe throbbing headache, drowsiness, confusion, fast heart rate.

Carbon Monoxide PPM Levels  
(model KN-COPP-B-LPM with digital display only)  
roded or disconnected vent pipes, loose or cracked furnace  
exchangers.  
Model KN-COPP-B-LPM is equipped with a digital display that shows  
levels of CO (displayed in PPM – parts per million). Learn the difference  
between dangerous, high, mid and low levels.  
• Vehicles and other combustion engines running in an open or  
closed garage, attached or near a home.  
• Burning charcoal or fuel in grills and hibachis in an enclosed area.  
Conditions That Can Produce Carbon Monoxide  
The following conditions can result in transient CO situations:  
Dangerous Levels:  
When someone is experiencing symptoms of CO poisoning and CO read-  
ings 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 veloc-  
ity, 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: Model KN-COB-B-LPM does not have a digital dis-  
play and does not display carbon monoxide levels in PPM. If the  
alarm sounds, it should be treated as a potentially serious condi-  
tion. 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.  
Possible Sources of Carbon Monoxide  
To be safe, know the possible sources of CO in your home. Keep fuel-  
burning appliances and their chimneys and vents in good working  
condition. Learn the early symptoms of exposure, and if you suspect CO  
poisoning, 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 com-  
pany 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, pro-  
pane, 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:  
Information About Carbon Monoxide Alarms –  
What They Can and Cannot Do:  
• 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, cor-

2. Product Features and Specifications  
Because carbon monoxide is a cumulative poison, long-term exposures 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.  
Test / Reset  
Button  
Green,  
Power LED  
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 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 temporar-  
ily solved, it’s crucial that the source of the CO is determined and that  
the appropriate repairs are made.  
Red,  
Alarm LED  
This CO alarm is designed to act as a monitor; it is not designed for use  
as a short-term testing device to perform a quick check for the presence  
of CO.  
Model KN-COB-B-LPM  
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.

CO alarms can only sense CO that reaches the unit’s sensor. It’s possible  
that CO may be present in other areas without reaching the alarm. The  
rate and ability that which CO reaches the alarm may be affected by:  
• Doors or other obstructions.  
• Fresh air from a vent, an open window or other source.  
Peak Level Button  
• CO being present on one level of the home and not reach 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).  
Digital Display  
Model KN-COPP-B-LPM  
with digital display  
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.  
WARNING: After seven (7) years from initial power up, this alarm  
will “beep” two times every 30 seconds to indicate that it is time  
to replace the alarm. Replace the alarm immediately! It will not  
detect CO in this condition.  
CO alarms should not 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.  
To help identify the date to replace the alarm, a label has been affixed  
to the side of the alarm. Write the “replace by” date (seven years from  
power up) in a permanent marker on this label.

Operating Characteristics  
Carbon Monoxide Alarm Indicator  
Peak Level Memory (model KN-COPP-B-LPM only)  
When the alarm senses a dangerous level of CO, the unit will emit a  
loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5  
seconds of silence, repeating for as long as dangerous conditions exist.  
The red Alarm LED will flash the same pattern and the digital display  
(where equipped) will indicate CO concentrations in parts per million  
(PPM).  
When the Peak Level button is pressed and held, the display shows  
the highest CO reading taken by the CO alarm since  
its last reset or power up. In this example 120 PPM  
was the maximum amount of CO recorded since the  
unit was last reset.  
Sample Peak

The Peak Level display feature will display levels  
between 11-999 PPM. Although the Peak Level  
feature will display levels below 30 PPM, these levels  
will not result in an alarm no matter how long the

NOTE: This unit is sealed. The cover is not removable.  
device is exposed to these levels. The Peak Level feature is helpful in  
identifying if you have had a CO reading since resetting the alarm.  
Due to the loudness of the alarm, we suggest that you place your  
fingers over the sounder opening while testing your alarm.  
Concentrations of CO between 1 and 30 PPM can often occur in  
normal, everyday conditions. Concentrations of CO below 30 PPM may  
be an indication of a transient condition that may appear today and  
never reappear. Some CO conditions may start out as low level leaks  
but could develop into CO concentrations that may become harmful.  
Caution: Continuous exposure to the high sound level of this  
alarm over an extended period of time may cause hearing loss.  
Testing  
To test the alarm, press the Test/Reset button. If the unit is operating  
properly, you will hear 4 quick beeps – followed by 5 seconds of silence  
– followed by 4 quick beeps. (For model KN-COPP-B-LPM with digital  
display: The display will show three “eights” and then show a number  
– and then show a number between 150 and 300). The red LED will  
flash along with the beeps. Within several seconds the unit will return  
to monitor for CO. Note: You do not need to press the Test button  
to take a CO reading.  
If this happens, the CO alarm will detect the dangerous level and  
alarm, notifying you and others of the conditions. DO NOT ignore  
high concentration readings above 30 PPM or a CO alarming  
device that is in alarm.  
Peak Level Memory Reset  
Press the Peak Level button; with the button still pressed, press the Test/  
Reset button for two seconds and release. The number on the display  
will turn to “0”, the memory will be cleared and the alarm will begin  
monitoring for CO. The Peak Level memory is also reset when the unit  
loses power.  
Maintenance Tips  
To keep your alarm in good working order, you must follow these 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.  
• 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.
