Quick Set Up Guide  
We urge you to read this entire manual  
in the sequence it is presented.  
Listed below are six easy steps for setting up your Carrier CO alarm.  
Please read this entire guide for complete information.  
Setting up your alarm for first time operation:  
Step 1  
Determine the best location for your CO alarm(s). Usually  
this is in or near bedrooms. The alarm should be located where it can  
wake you if it alarms at night. Refer to page 8 for installation location  
information.  
Step 2  
Your CO alarm is equipped to be mounted as a corded unit, a direct  
plug unit or a table top unit. In the “as shipped” configuration, the unit  
can be plugged directly into a wall socket. (If your outlets are mount-  
ed horizontally, please refer to page 11, “to rotate adapter”). If the  
transformer/adapter is taken out of the unit, the alarm can be mount-  
ed on the wall at eye level, while the transformer is plugged into a  
wall socket. The unit can also be set on a table if the support at the  
bottom of the unit is pulled out (see “rear view” illustration on page  
10). Refer to pages 10-12 for further information on installing your  
alarm.  
Step 3  
A Carrier rechargeable battery pack is provided for backup in the  
event of a power outage. To install the battery pack, open the back  
door and align the connector with the slot in the battery. Insure the  
orientation of the two alignment ribs align with the slots in the battery  
case.  
Press the connector in until it is fully seated. Depending on the  
charge state of the battery pack (the battery packs can have different  
amounts of energy stored in them due to storage time), you may hear  
the alarm sound briefly to indicate the alarm is receiving power.  
Place battery pack into battery compartment and replace back door  
(refer to page 13).  
Note: Battery backup will be limited until the battery has fully  
charged. It may take up to 24 hours for the battery back up to fully  
charge.  
Step 4  
Plug the alarm into a standard, unswitched 120 volt AC electric outlet  
in one of the configurations listed in step 2.

Quick Set Up Guide  
Step 5  
If the battery pack has a full charge when first powered up, you will  
see three eights in the digital display indicating the alarm is warming  
up. After approximately 20 seconds, the first reading will be dis-  
played. The number on the display should be “0”. If the battery pack  
is partially charged,“Lb”(Low battery) will flash every second alternat-  
ing with a “0” until the battery is charged. If this occurs, see page 13  
for complete information.  
Step 6  
Make sure the red dot in the digital display is blinking. Test the unit’s  
operation by pressing and releasing the Test/ Reset button. Within  
15 seconds you will hear 4 quick “chirps” - followed by 5 seconds of  
silence - followed by 4 quick “chirps”.  
While testing the alarm, have someone else check that the alarm  
can be heard easily from the sleeping areas. For complete testing  
information, refer to page 16.  
Caution: Continuous exposure to the loud 85 decibel alarm at close  
range over an extended period of time may cause hearing loss.  
Your Carrier CO alarm is now monitoring for the presence of carbon  
monoxide.

Introduction  
This Carrier carbon monoxide (CO) alarm is an important part of your  
family’s home safety plan. As a new owner of a CO alarm, there are  
some basic facts you should know for your protection and convenience.  
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 carbon monoxide 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 pos-  
sibly hear the fire burning. You can also readily see if your smoke alarm  
is alarming in a non-emergency situation, for example someone smoked  
up the kitchen with some burnt toast. 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.  
Carbon monoxide (CO) is invisible, odorless, tasteless, nonirritating, poi-  
sonous gas that is completely undetectable to your senses. It is created  
when any fuel is burned – gasoline, propane, natural gas, oil, wood, coal,  
and even tobacco. 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 carbon monoxide alarm.  
Please take the time to completely read this guide to familiarize yourself  
with the facts about carbon monoxide, how your new unit works, and  
what to do if it alarms. Find a handy place to keep this manual so that it  
will be readily available when you have a question.  
Thank you for making Carrier a part of your complete home safety pro-  
gram. With proper installation and use, your new Carrier CO alarm will  
provide you with years of dependable service.

Features  
Digital Display  
The continuous digital display shows you the level of carbon monoxide (if any) the  
unit is sensing. The unit updates the digital display every 15 seconds .  
Note: If the unit does not sense any CO, the reading is zero (0). In most homes,  
the unit reads “0” all the time. A reading of “0” is expected under normal conditions.  
The blinking dot after the number shows the unit is operating.  
Test/Reset Button  
The Test/Reset button has three functions:  
1. Press this button to test the unit weekly (see page 16 for further  
details).  
2. Press this button to silence the alarm. This will reset the unit and it  
will then start monitoring for CO. If the CO concentration is above 70  
ppm the alarm will again sound within 6 minutes.  
3. Press the Test/Reset button to reset peak level memory. (See page  
19).  
Peak Level Button  
By pressing this button, you can see the peak CO level recorded by  
the alarm since it was last cleared or unplugged. This Carrier feature  
allows you (or a heating contractor or a fireman) to see exactly how  
serious the CO problem you have so you can react accordingly.  
Sensor  
The 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. An alarm condition is 4 quick “chirps” – followed  
by 5 seconds of silence – followed by 4 quick “chirps”. This pattern  
repeats until the alarm is silenced or a high level of CO is no longer  
present.  
Caution: Continuous exposure to this sound level at close range  
over an extended period of time may cause hearing loss. We recom-  
mend you cover the sounder with your finger or thumb while testing  
the alarm.  
Keyholes  
When the alarm is mounted to the wall, the keyholes slide onto the  
screws mounted in the wall.

Features  
What Carbon Monoxide Alarms Can and Cannot Do  
CO alarms are designed to sense unacceptable levels of CO from  
malfunctioning furnaces, appliances, gas engines or other sources.  
This Carbon Monoxide alarm is not a substitute for installing and  
maintaining an operational smoke alarm.  
CO alarms provide early warning of the presence of carbon monox-  
ide, usually before a healthy adult would experience symptoms.  
This early warning is possible, however, only if your Carrier CO  
alarm is located, installed and maintained as described in this  
user’s guide.  
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.  
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. See back page for  
warranty information. This CO alarm also has an "operational end  
of life" feature which will indicate when to replace the alarm. See  
page 25 for details of this feature.  
CO alarms can only sense CO that reaches the unit’s sensor.  
Carbon monoxide may be present in other areas without reaching  
the alarm. The rate at which CO reaches the unit may be affected  
by doors or other obstructions. In addition, fresh air from a vent or  
open window or any other source may prevent CO from reaching  
the sensor. Please observe cautions on page 8 “Where to install  
your alarm.”  
CO could be present on one level of the home and not reach a CO  
alarm installed on a different level. For example, CO in the base-  
ment may not reach an alarm on the second level, near the bed-  
rooms. For this reason, we recommend you provide complete cov-  
erage by placing a CO alarm on every level of the home.  
CO alarms are not smoke alarms. CO alarms do not sense smoke or  
fire. 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.

Installation  
Where to Install Your CO Alarm  
Your Carrier CO alarm should be mounted in or near bedrooms and liv-  
ing areas. It is recommended that you install a Carrier 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  
requirements as a guide to the location of your Carrier CO alarm(s).  
WHEN CHOOSING YOUR INSTALLATION 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 BED-  
ROOMS, NOT IN THE BASEMENT OR FURNACE ROOM.  
Recommended Locations  
DINING  
KITCHEN BEDROOM BEDROOM  
LIVING ROOM  
BEDROOM  
Two labels have been provided with 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 win-  
dow.  
CAUTION: This alarm will only indicate the presence of carbon monox-  
ide at the sensor. Carbon monoxide may be present in other areas.  
IMPORTANT: Improper location can affect the sensitive electronic com-  
ponents in this alarm. Please see the next section describing where NOT  
to install this alarm.

Installation  
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 :  
It is recommended that you do not 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. Within hours of starting a vehicle and  
backing it out of the garage, the levels present 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 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 Carrier CO alarm near a cooking or heating appliance, install  
AT LEAST 5 feet away from 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 alarm not to operate properly.  
Do not obstruct the vents located at the top and bottom of 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 space, such as peaks of vaulted ceilings or gabled roofs,  
where carbon monoxide may not reach the sensor in time to provide early warn-  
ing.  
Do not install in turbulent air from ceiling fans. Do not install near doors and win-  
dows 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 sensor to  
display an inaccurate reading in the presence of CO.  
Do not install this alarm in a switch- or dimmer-controlled outlet.  
Do not install in areas where the temperature is colder than 40˚F (4.4˚C) or hot-  
ter than 100˚F (37.8˚C). These areas include unconditioned crawl spaces, attics,  
porches and garages. Extreme temperatures will affect the sensitivity of the alarm.  
Do not install CO alarm near deep cell large batteries. Large batteries have emis-  
sions that can cause the alarm to perform at less than optimum performance.

Installation  
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 competing for  
limited internal air.  
4) Vent pipe connections vibrating loose from clothes dryers, furnaces or  
water heaters.  
5) Obstructions in or unconventional vent pipe designs which can amplify  
the above situations.  
Extended operation of unvented fuel burning devices (range, oven, fire-  
place, etc.).  
Temperature inversions which can trap exhaust gasses near the ground.  
Car idling in an open or closed attached garage, or near a home.  
How to InstallYour Alarm  
Your Carrier 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.  
Direct Plug Alarm  
First, refer to “Where to Install Your CO Alarm” on  
page 8 for general guidelines as to where to locate  
your CO alarm.

battery.  
Battery  
Compartment  
During the first 10-hour initial charge period or, until the battery has charged,  
"Lb" will be displayed along with the CO level (usually "0") and without an  
audible "chirp". When the initial charge is complete, the "Lb" will disappear.  
If however, after 10 hours the battery is not charging properly, "Lb" may con-  
tinue to flash AND there will be an audible "chirp" once every 15 seconds  
indicating the battery is not charging. If this occurs, make sure the connec-  
tion between the battery and the alarm is correctly oriented and fully seated.  
If not, disconnect the battery and reconnect insuring the alignment ribs  
match the slots in the battery. If it is properly connected and fully seated and  
"Lb" is still displayed along with an audible "chirp", contact customer service.

Battery Backup Operation  
Battery Backup Operation  
When the alarm is unplugged or loses AC power and the battery pack is fully  
charged, the alarm will automatically switch to battery backup operation and  
you will notice the following:  
For the first five minutes of operation on battery, the alarm  
will operate as if on AC power.  
However, after five minutes of operation, to conserve battery  
capacity, the display will flash the CO level (usually "0") once  
every 60 seconds.  
Caution: If the unit detects CO and enters an alarm state while in bat-  
tery back-up condition, the CO level will be displayed and the audible  
alarm pattern of four quick beeps will sound once every 60 seconds.  
Battery Back-up Operation in Low Battery "Lb" Condition:  
When the battery pack is not fully charged, the unit will begin displaying "Lb"  
and "chirp" once every 15 seconds. This will last approximately 7 hours to  
warn you the battery is losing capacity. Apply AC power to charge battery as  
soon as possible.  
NOTE: While in the low battery "Lb" warning mode, the unit is sensing  
for and will alarm if CO is detected.  
Battery Back-up Operation inTrouble Alarm Condition:  
When the battery pack capacity has been discharged to a state where it can  
no longer provide enough power to detect CO and operate the alarm, it will  
enter a trouble alarm condition. The display will go blank and the alarm will  
give an audible trouble "chirp" once every 60 seconds. This will continue for  
approximately 7 hours after which time the alarm will no longer "chirp" to warn  
of a trouble condition.  
WARNING:THE UNIT WILL NOT DETECT CO WHILE INTHETROU-  
BLE ALARM CONDITION, BLANK DISPLAY, AND ONE AUDIBLETROU-  
BLE "CHIRP" EVERY 60 SECONDS. APPLY AC POWERTO CHARGE  
THE BATTERY AS SOON AS POSSIBLE.  
When AC power is restored, the alarm will automatically switch back to nor-  
mal operating mode and begin charging the battery pack to full capacity. After  
continued operation on battery backup, "Lb" may flash while the battery is  
recharging and will continue until fully charged.  
Constant exposures to high or low humidity may reduce  
battery life.  
WARNING:  
Replace the battery pack only with a Carrier rechargeable bat-  
tery pack. Replacement battery packs can be purchased from  
Carrier customer service. See page 28 for additional precau-  
tions regarding the rechargeable battery pack.

Within 20 seconds, your CO alarm will start monitoring for CO. The num-  
ber indicates a measurement of carbon monoxide in parts per million  
(ppm). Note: The number will probably be zero (0). This is a normal con-  
dition for most households and shows that no measurable amount of CO  
has been detected.  
The alarm has begun monitoring the air for carbon monoxide and will con-  
tinue to do so as long as it receives power.

Operation  
Testing the Electronics  
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 below, have it replaced immediately. See “How to know if your  
alarm is malfunctioning” on page 17 for a description of the characteris-  
tics of a malfunctioning alarm and what you should do if a malfunction  
occurs.  
Observe the alarm weekly to make sure the red dot is blink-  
ing, indicating normal operation.  
If the dot is not blinking, unplug the alarm, then plug it in  
again. This will clear the alarm for restart. If the dot does  
not resume blinking, your alarm may be malfunctioning.  
Blinking Dot  
To test the alarm, press the Test/Reset button. If the unit is operating  
properly, you should notice the following:  
The display shows three eights  
, and then shows a num-  
ber (usually around 200). You will then hear 4 quick beeps  
– followed by 5 seconds of silence – followed by 4 quick beeps.  
The unit will then show the three eights for several seconds. It  
will then return to monitoring for carbon monoxide.  
Familiarize yourself and household members with the alarm pattern  
described above. In the event of a CO incident, this 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 read-  
ings are automatically shown on the alarm’s digital display. If the alarm  
shows zero (0), then no measurable amount of CO has been sensed by  
the alarm within the past 15 seconds.

Operation  
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 20 seconds., and  
– An “Err” message will appear on the digital display  
OR,  
Malfunction Signal Group 2 - Microprocessor Failure  
– The alarm will sound continuously, and  
– The digital display will be blank, and  
– The alarm cannot be shut off by pushing the “Test/Reset” button  
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, and do not confuse these sig-  
nals with an alarm. After reading the information above, if you are still unsure whether  
your alarm is operating properly, call the Kidde toll-free consumer hotline at 1-800-880-  
6788 to do a quick diagnostic check of the alarm over the phone. The customer serv-  
ice representative will be able to assist you and answer your questions.  
Never ignore a CO alarm.Atrue alarm is an indication of potentially dangerous lev-  
els of carbon monoxide. CO alarms are designed to alert you to the presence of  
carbon monoxide before an emergency, before most people would experience  
symptoms of carbon monoxide poisoning, allowing time to resolve the problem  
calmly.

Operation  
How to Care for Your Alarm  
To keep your alarm in good working order, you must follow these simple  
steps:  
WHAT YOU SHOULD DO:  
Test the alarm once a week by pressing the Test/Reset button (see  
page 5).  
Vacuum the alarm cover once a month to remove accumulated dust.  
Use the soft brush attachment of your vacuum cleaner, and unplug the  
alarm from the electrical outlet before vacuuming.  
Instruct children never to touch, unplug or otherwise interfere with the  
alarm. Warn children of the dangers of CO poisoning.  
WHAT YOU SHOULD NOT DO:  
Never use detergents or solvents to clean the alarm. Chemicals can per-  
manently damage or temporarily contaminate the sensor.  
Avoid spraying air fresheners, 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 diaper pail, as high  
amounts of methane gas can cause temporary readings on the digital display.  
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 it in a plastic bag during the project.  
The following is a list of substances that at high levels can affect the sen-  
sor and cause temporary readings on the digital display that are not carbon  
monoxide readings:  
Methane, propane, iso-butane, ethylene, ethanol, alcohol, iso-propanol,  
benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, and sulfur  
dioxides.  
Also most aerosol spray, alcohol based products, paint, thinner, solvent,  
adhesives, hair spray, aftershave, perfume, auto exhaust (cold start) and  
some cleaning agents.

Operation  
Peak Level Memory  
The peak level feature is helpful in identifying CO occurrences below 30 PPM.  
Although the unit will not automatically display levels below 30 PPM, it will  
detect and store these readings in memory. By pressing the peak level but-  
ton, concentration levels as low as 11 and up to 999 PPM will be displayed.  
Concentrations of CO between 0 and 30 PPM can often occur in normal,  
everyday conditions. Concentrations of CO below 30 PPM may be an indi-  
cation of a transient condition that may appear today and never reappear.  
Just a few examples of conditions and/or sources that may cause readings  
are heavy automobile traffic, a starting a vehicle in an attached garage, an  
appliance that emits CO when starting up, a fire in a fireplace or charcoal in  
a nearby barbecue. A temperature inversion can trap CO generated by traf-  
fic and other fuel burning appliances causing readings of CO.  
Normally, the digital display will read “0” and under certain conditions you may  
notice levels of 30 or more for short periods of time, by using the Peak level  
memory feature on the Carrier CO alarm you can view concentrations of CO  
between 11 and 30 PPM. Use the concentrations shown in memory as a tool  
in identifying the source of the CO. It may be helpful to purchase additional  
Carrier COAlarms to place in different locations throughout your house to iso-  
late the CO source. Monitor the CO concentrations shown in the peak level  
memory to see if readings occur in certain areas at certain times of the day,  
or near a particular appliance.  
Once the source is located, correcting the problem may be as easy as open-  
ing a window, venting an appliance, backing a running car out of the garage  
a safe distance from living quarters and closing the garage door. It could be  
possible that a weather condition caused the reading and the condition may  
or may not happen again.  
Some CO conditions may start out as low level leaks but could develop into  
CO concentrations that could become harmful. If this happens, the CO alarm  
will detect the dangerous level and alarm, notifying you and others of the con-  
ditions. DO NOT ignore high concentration readings above 30 PPM or a CO  
alarming device that is in alarm.  
CO concentrations displayed below 30 PPM in "Peak Level" memory are for  
reference only and the accuracy of the concentration shown may not be as  
accurate as noted on page 24.  
To Reset the Peak Level Memory…  
Step 1. Press 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 number on the display will turn to “0”. The memory has now been  
cleared and the alarm will begin monitoring for CO within a few minutes.

What To Do When the Alarm Sounds  
Determine if anyone in the household is experiencing symptoms of CO poison-  
ing. 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 them-  
selves 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:  
Become familiar with these common symptoms from CO poisoning  
.
Common Mild Exposure Symptoms:  
Headaches, running nose, sore eyes, often described as  
“flu” like symptoms.  
Common Medium Exposure Symptoms:  
Dizziness, drowsiness, vomiting  
Common Extreme Exposure Symptoms:  
Unconsciousness, brain damage, death.  
If you experience even mild symptoms of CO  
soning, consult your doctor immediately!

When the CO alarm senses a dangerous level of CO, the unit will emit a loud  
alarm pattern. The alarm pattern is 4 short “chirps” – followed by 5 seconds of  
silence – followed by 4 short “chirps”. (Note: When the unit is disconnected  
from the 120V power supply and is on battery backup, the alarm pattern will  
continue for the first 5 minutes after detecting CO and then the cycle will repeat  
every one minute). Know how to respond to a CO emergency. Periodically  
review this user’s guide and discuss with all members of your family.

Specifications  
How the Unit Determines When to Alarm  
Your Carrier CO alarm uses advanced technology to monitor  
the environment in your home and warn you of unacceptable lev-  
els of carbon monoxide. An internal microcomputer works  
together with the sensor inside the alarm to determine the lev-  
els of carbon monoxide in the air and to calculate the rate that  
CO would be absorbed into the human body. The microcom-  
puter is calibrated to trigger the unit’s alarm before most people  
would experience any symptoms of carbon monoxide poison-  
ing. Because carbon monoxide is a cumulative poison, long-  
term exposures to low levels can cause symptoms, as well as  
short-term exposures to high levels. Your unit has a time  
weighted alarm, so the higher the level of carbon monoxide  
present, the sooner the alarm will be triggered.  
WARNING: This device is designed to protect individuals from  
acute effects of carbon monoxide exposure. It will not fully  
safeguard 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 monoxide concentrations  
under 30 ppm.  
Replacement of Alarm  
Eight 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 provided that has “Replace by” printed on it. Write  
the replace by date on the label and affix it to the front of the  
alarm so that it is visible after mounting. The date written on  
the label should be after eight (8) years of cumulative power.  
REPLACE IMMEDIATELY! UNIT WILL NOT DETECT CO IN THIS CONDITION.

Display Readings  
Your new Carrier carbon monoxide alarm is a sophisticated electronic  
device – yet very simple to understand. Basically, the unit will display  
a “0” if it senses 30 PPM of CO or less and if you have a good backup  
battery pack installed.  
If it senses carbon monoxide, it will display a reading so you can see  
if you have a non-threatening or emergency situation.  
However, if the backup battery pack is low or missing, or if the unit  
malfunctions, it will display other readings (and alarm differently) to  
alert you that something is wrong with the alarm.  
Please familiarize yourself and other family members to the difference  
between a CO reading and a reading signifying a problem with the  
alarm itself.

Li-Ion Battery Handling Precautions  
Handling  
• Do not use the battery for a purpose other than for the alarm it is  
specified.  
• Do not recharge the battery using any charging circuit other than the  
one provided in the alarm. A recharging operation under non-  
conforming recharging conditions can cause electrolyte leakage,  
overheating, smoke emission, bulging/bursting and/or ignition.  
• Do not discard the battery into fire or heat it under any circumstances.  
Otherwise, it may cause the battery to explode. Do not connect  
the battery to an electrical outlet.  
• Do not connect the positive and negative terminals of the bat-  
tery with any conductor such as metal wires. Do not store the  
battery or transport it together with any metal objects.  
28

Li-Ion Battery Handling Precautions  
• Do not disassemble or modify the battery pack under any  
circumstances. Disassembling the battery can cause internal  
shorts, resulting in bulging/bursting due to excess gas genera-  
tion, overheat, ignition, explosion or other problems.  
• Do not pierce the battery with sharp objects or subject to any  
other mechanical forces. Do not use an apparently dam-  
aged or deformed battery.  
• Do not use or leave the battery near a heat source such as  
a fire or heater. Do not place the battery in microwave oven or  
on induction heaters.  
• Do not use or subject the battery to intense sunlight or hot  
temperatures. Otherwise, electrolyte leakage, overheating and/or  
smoke emission can occur. Also, its guaranteed perform-  
ance will be lost and/or its service life will be shortened.  
• Do not subject the battery to static electricity. Otherwise, the  
built-in safety/protection circuits can be damaged by static volt-  
ages, possibly leading to leakage, overheating, smoke emis-  
sion, bursting and/or ignition.  
• Do not immerse the battery in liquids such as fresh or salt  
water, beverages (fruit juices and coffee, etc.).  
• If the battery leaks, and the electrolyte gets into the eyes, the  
skin or other part of the body, rinse the body part with clean  
running water and immediately seek medical attention.  
• Li-Ion batteries may be disposed of in normal household  
waste. Contact local landfill for disposal or recycling practices  
in your area.  
Battery Storage (When Detached From the Alarm)  
• Store the battery in a location where children cannot reach it.  
Store the battery in a cool and dry storage area. Storing the bat-  
tery in temperatures above 40°C will lead to permanent bat-  
tery damage. If a refrigerator is used for storage, the battery  
should be placed in a plastic bag for protection against con-  
densation.  
• The proper operating/recharging temperature range is from 0 to  
40°C. An operating/recharging condition outside this range  
can lead to battery damage, overheating or other problems.
