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 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 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:  
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.  
Mid Levels:  
• Simultaneous operation of several fuel-burning appliances competing  
for limited internal air.  
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:  
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).  
• Obstructions in, or unconventional, vent pipe designs which can  
amplify the above situations.  
Extended operation of unvented fuel-burning devices (range, oven,  
fireplace, etc.).  
IMPORTANT: Model KN-COB-DP-LS does not have a digital display  
and does not display carbon monoxide levels in PPM. If the alarm  
sounds, it should be treated as a potentially serious condition.

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.

Model KN-COB-DP-LS  
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.  
Sounder  
Alarm  
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.

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 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.  
• 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).  
Ta m p e r-Re sist Fe a t u re  
This is an alert to notify consumers the unit has been unplugged or has  
come loose from the outlet. This feature is not activated for two minutes  
after power is first supplied to give you time to plug the unit in after  
activating the battery. This feature is also disabled once the battery volt-  
age has reached a level to cause a low battery warning chirp. This can  
be defeated for two minutes by pressing the Test button while the unit  
is removed from the plug to allow the battery to be changed without  
the 85dB alarm sounding. The feature can also be disabled by pressing  
in the Tamper-Resist Activation switch and moving the disable slide  
towards the switch. Use the included screw to secure the battery cover  
and increase tamper resistance.  
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 on properly installing this CO alarm.  
CO alarms should not be used to detect the presence of natural gas  
(methane), propane, butane, or other combustible fuels.

If the 9V battery is missing or battery power is low, the unit will chirp  
every 15 seconds to indicate the battery must be replaced. If the battery  
is depleted beyond the point of having the capacity to operate the unit,  
it will chirp every 30 to 45 seconds and will NOT respond to the test  
button being pressed if operating on battery power. THE BATTERY  
MUST BE REPLACED IMMEDIATELY!  
CO alarms should be mounted in or  
near bedrooms and living areas. It is  
recommended that you install a Kidde  
CO alarm on each level of your home.

• When wall mounting, place out of reach of children. Under no cir-  
cumstances should children be allowed to handle the CO alarm.  
Lo ca t io n s To Avo id  
IMPORTANT: Improper location can affect the sensitive electronic com-  
ponents in this alarm. To avoid causing damage to the unit, to provide  
optimum performance, and to prevent unnecessary nuisance alarms:  
IMPORTANT: Seven (7) years after the initial pow er up, this alarm  
w ill “beep” every 30 seconds to indicate that it is time to replace  
the alarm. Replace the alarm immediately! It w ill not detect CO in  
this condition.  
• Do not install in kitchens, garages or furnace rooms that may expose  
the sensor to substances that could damage or contaminate it.  
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.  
• Do not install in areas where the temperature is colder than 40°F  
(4.4°C) or hotter than 100°F (37.8°C) such as crawl spaces, attics,  
porches and garages.  
Temperature:  
Operating Range: 40°F (4.4°C) to 100°F (37.8°C)  
• Do not install within 5 ft. of heating or cooking appliances. (Kidde  
recommends 15 ft. to prevent nuisance alarms).  
Humidity:  
Operating range: 10-95% non-condensing  
• Do not install near vents, flues, chimneys or any forced/unforced air  
ventilation openings.  
Audible Alarm:  
85+ dB at 10’ @ 3.4±0.5 KHz pulsing alarm  
• Do not install near ceiling fans, doors, windows or areas directly  
exposed to the weather.  
Sensor:  
Electrochemical  
• Do not install in dead air spaces, such as peaks of vaulted ceilings or  
gabled roofs, where CO may not reach the sensor in time to provide  
early warning.  
Pow er:  
120 volts AC, 60 Hz, 60 mA max, 9 volt battery back-up  
• Do not install this unit near deep-cell large batteries. Large batteries  
have emissions that can cause the alarm to perform at less than opti-  
mum performance.  
Alarm Response Times:  
70 PPM = 60-240 min., 150 PPM = 10-50 min., 400 PPM = 4-15 min.  
• Do not obstruct the vents located on the alarm. Do not place the  
alarm where drapes, furniture or other objects block the flow of air to  
the vents.  
• Do not install on a switched or dimmer-controlled outlet.

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.  
When the Model KN-COB-DP-LS CO alarm loses power: If you have a good  
9V battery installed, the alarm will automatically switch to the battery back-  
up mode and the green LED will flash approximately every 10 seconds. The  
unit will continue to operate normally and detect CO for at least 20 hours.  
To install:  
1. Choose a standard 120V unswitched outlet to  
plug the alarm into.  
When the Model KN-COB-DP-LS CO alarm loses pow er: If you have a  
good 9V battery installed, the alarm will automatically switch to the battery  
backup mode and the green LED will flash approximately every 10 seconds.  
The unit will continue to operate normally and detect CO for at least 20  
hours.  
2. If outlet is mounted sideways (horizontally), rotate  
the plug and plug the alarm in.

If the battery is low or missing, or if the unit malfunctions, it will alarm dif-  
ferently to alert you of specific conditions. Please familiarize yourself, and  
other family members, of the difference between a CO alarm and an indica-  
tion signifying a problem with the unit.  
Im p o rt a n t La b e ls Pro vid e d  
Two labels have been provided that have important information on what  
to do in case of an alarm. Add the phone number of your emergency  
service provider in the space provided. Place one label next to the alarm  
after it is mounted, and one label near a fresh air source such as a door  
or window.  
When AC power is restored, the alarm will automatically switch back to nor-  
mal operating mode and the green LED will come on continuously. Observe  
the CO alarm regularly to make sure the green Operate LED is on, indicating  
normal operation. If the green Operate LED is not on, unplug the CO alarm,  
then plug it in again. This will clear the alarm for restart. If the green oper-  
ate LED does not light, your CO alarm may be malfunctioning.

The following table describes the audible alarm patterns and the recom-  
mended actions to take.  
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. This cycle repeats as long as a dangerous CO condi-  
tions exist. The red Alarm LED will flash the same pattern (and the PPM  
will be displayed on alarms with digital displays).

Whenever the alarm is operating, the digital display will display 0” to indi-  
cate the unit is monitoring for CO. If the alarm senses dangerous levels of  
CO, the digital display will indicate the CO concentration in parts per million  
(PPM), and the alarm will emit an audible alarm pattern.

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. 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 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.  
This alarm will display a 0” if CO concentrations between 0 and 30 PPM  
have been detected within the last 15 seconds.  
When the unit is first powered up, the digital display will show three  
“eights” – indicating the alarm is in the start-up mode. The three “eights”  
will remain for approximately 20 seconds. After 20 seconds, the alarm  
should display 0” and begin monitoring the air for CO and will continue to  
do so as long as it receives power.  
Concentrations of CO between 1 and 30 PPM can often occur in nor-  
mal, 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.

• Staining or stripping floors or furniture, painting or wall-papering  
• Using aerosols or adhesives  
GP1604A  
These batteries can be purchased where you bought the alarm or at a  
local hardware store. Use of a different battery may have a detrimental  
effect on the alarm operation.  
WARNING: Reinstall the CO Alarm as soon as possible to assure contin-  
uous 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:  
The 9 volt battery is not rechargeable. If the 9 volt battery is missing,  
disconnected, or if the batterys power is low, a red LED flash will occur  
once every 15 seconds, accompanied by an audible beep. If this  
happens, the battery must be replaced. (For model KN-COP-DP-LS  
w ith digital display: Lb” will be displayed alternately with the current  
CO reading once every second).  
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl  
acetate, hydrogen, hydrogen sulfide and sulfur dioxide.  
• Also most aerosol sprays, alcohol based products, paint, thinner, sol-  
vent, adhesive, hair spray, after shave, perfume, auto exhaust (cold  
start) and some cleaning agents.  
To replace battery:  
Remove the screw, if it has been used, that is holding the battery door  
located on the back of the unit. Slide the battery door toward the back  
oF the alarm to release it. Remove the battery and replace it with one of  
the approved replacement batteries. Reinstall the back door and replace  
the screw, if it has been used  
IMPORTANT: Constant exposures to high or low humidity may reduce  
battery life. A good safety measure is to replace the battery at least once  
a year, or at the same time as you change your clocks for daylight saving  
time.  
After installing or changing the battery, reinstall your alarm. Test your  
alarm by using the Test/Reset button and check that the green LED is on.  
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.
