CARBON MONOXIDE ALARM
OWNER'S MANUAL
PLEASE READ AND SAVE!
WHAT YOU SHOULD KNOW ABOUT CO
Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a cumulative
poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn
infants with no effect on the mother.
The following symptoms are related to CARBON MONOXIDE POISONING:
MILD EXPOSURE
Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).
MEDIUM EXPOSURE
Severe throbbing headache, drowsiness, confusion, fast heart rate.
EXTREME EXPOSURE
Unconsciousness, convulsions, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware they are
not well, but they become so disoriented that they are unable to save themselves by either exiting the
building or calling for assistance. Young children and household pets may be the first affected.
Your CO alarm is designed to detect the toxic CO fumes that result from incomplete combustion, such
as those emitted from appliances, furnaces, fireplaces and auto exhaust.
A CO alarm is NOT A SUBSTITUTE for other combustible gas, fire or smoke alarms. This carbon
monoxide alarm is designed to detect carbon monoxide gas from ANY source of combustion.
CAUTION: This alarm will only indicate the presence of carbon monoxide gas surrounding its sensor.
Carbon monoxide gas may be present in other areas.
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. Individuals with medical problems may consider using warning devices which
provide audible and visual warnings for carbon monoxide concentrations under 30 PPM.
WHAT YOU SHOULD DO IF THE ALARM SOUNDS
Never disconnect a CO alarm to silence an alarm. The alarm will automatically sense when the level of
CO in the air falls below the danger level. You should stay outside the residence in fresh air until the
alarm is silenced. When the alarm sounds, do not stand too close to the alarm. The sound produced by
the alarm is loud because it is designed to awaken a person in an emergency. Prolonged exposure to
the alarm at a close distance may be harmful to your hearing.
IMPORTANT CONSIDERATIONS
YOUR CARBON MONOXIDE ALARM HAS BEEN DESIGNED AND IS
WARRANTED TO OPERATE FOR FIVE YEARS.
NOTE: MANUFACTURER RECOMMENDS REPLACEMENT OF ALARM FIVE
YEARS AFTER DATE OF PURCHASE.

MOUNTING LOCATION
This CO alarm can be mounted on the wall or ceiling.
WALL LOCATION: Locate the top of the alarm not more than 6 feet from the floor.
CEILING LOCATION: Alarm should be mounted as close as possible to the center of a hallway or
room. If this is not possible, the edge of the alarm should be at least 4 inches from any wall.
FIGURE 3
LOCATIONS TO AVOID
Nuisance alarms are caused by placing alarms where they will not operate properly. To avoid nuisance
alarms, do not place alarms:
– Within 5 feet (1.5m) of any cooking appliance.
– Near an open window or door, because the fresh air entering the opening may delay CO from
reaching the alarm.
– In damp or very humid areas or next to bathrooms with showers. Install alarms at least 10 feet (3m)
away from bathrooms.
– In very cold or very hot environments or in unheated buildings or outdoor rooms where the temperature
can go below or above the operating range of the alarm. Temperature limits for proper operation
are 40o -100oF (4.4o -38oC).
– Good ventilation is recommended when household cleaning supplies or similar contaminants are
used.
– Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions,
such as:
– Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).
– Negative pressure differential resulting from the use of exhaust fans.
– Simultaneous operation of several fuel burning appliances competing for limited internal air.
– Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.
– 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 which can trap exhaust gasses near the ground.
– Car idling in an open or closed attached garage, or near a home.
What Levels of CO Cause an Alarm?
Underwriters Laboratories Inc. UL2034 defines three specific alarm points by which all residential CO
alarms must alarm. They are measured in parts per million (ppm) of CO over time (in minutes).
UL2034 Required Alarm Points:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm of CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.

DEVELOPING YOUR OWN CO SAFETY PLAN
This CO alarm can quickly alert you to the presence of CO - it cannot prevent toxic CO emissions.
Please note that there are hazards against which CO detection may not be effective, such as gas leaks
or explosions. The ultimate responsibility for protection against toxic CO fumes rests solely on you.
Installing CO alarms is just the first step in protecting your family from toxic CO poisoning. We also
suggest that you create an effective, comprehensive safety program as outlined below.
1. Install CO alarms properly following the instructions in this manual. Keep your CO alarms clean - do
not wash. Wipe with a clean towel. Test your alarms weekly and repair or replace them when they no
longer function. As with any electronic product, alarms have a limited life and alarms that do not work
cannot protect you.
2. Develop a family escape plan and practice it with your entire family, especially small children.
– Draw a floor plan of your home and find two ways to exit from each room. There should be one
way to get out of each bedroom without opening the door.
– Teach children what the CO alarm signal means and how they must be prepared to leave the
residence by themselves if necessary.
– Decide on a meeting place a safe distance from your house and make sure all children understand
where they should go and wait if there is a dangerous CO condition.
– Conduct CO safety drills at least every 6 months to make sure that everyone, even small children,
knows what to do in order to escape safely.
– Know where to go to call the Fire Department from outside your residence.
This unit is designed to detect carbon monoxide (CO) entering its sensing chamber. It does not sense
combustible gas (such as natural gas, propane or butane), heat, smoke or flames.
NOTE: This CO alarm is designed for use within a single residential living unit only. In a multi-family
building, the alarm may not provide early warning for residents if it is placed outside of the residential
units, such as on outside porches, in corridors, lobbies, basements, or in other apartments. In multi-
family buildings, each residential unit should have detectors installed as previously indicated.
When properly located, installed, and maintained, this CO alarm is designed to provide early warning of
developing poisonous CO conditions at a reasonable cost. This alarm monitors the air, and when it
senses CO, it activates its built-in alarm. It can provide precious time for you and your family to escape
from your residence before CO can seriously injure or kill. However, such an early warning is possible
only if the alarm is located, installed, and maintained as specified in the Owners Manual.
IMPORTANT: WHAT YOUR CO ALARM CAN AND CANNOT DO
If the bedroom doors are usually closed at night, alarms should be placed in each bedroom as well as
in the common hallway between them.
CO alarms also may not sense CO on a different level of a residence or building. For example, a
second floor alarm may not sense a CO leak on the first floor or in the basement. Therefore, alarms
should be placed on every level of a residence or building.
If the alarm is located outside of a bedroom, it may not wake up a sound sleeper, especially if the
bedroom door is closed or only partly open. If the alarm is located on a different level of the residence
than the bedrooms, it is even less likely to wake up people sleeping in the bedroom.
Installing CO alarms may qualify you for lower homeowner's insurance rates, but CO alarms are not a
substitute for insurance. Homeowners and renters should continue to insure their lives and property.
WARNING: The Model CD-9000 alarm is not designed for marine use.

• Remove the mounting plate from the back of the alarm by holding the mounting plate and twisting the
alarm in the direction indicated by the "OFF" arrow on the alarm cover.
• To ensure aesthetic alignment of the alarm with the hallway or wall, the "A" line on the mounting plate
must be parallel with the hallway walls when ceiling mounting or horizontal when wall mounting (See
Steps A and B).
• After selecting the proper carbon monoxide alarm location as described in Figure 1, attach the
mounting plate on the wall. Be sure the "UP FOR WALL MOUNTING" text and arrow are facing up.
Use the screws and anchors provided to secure the mounting plate.
• Install the battery in the correct orientation as noted on the inside of the battery door. The alarm will
beep once, indicating proper battery installation.
CAUTION! IF NO BATTERY IS INSTALLED, THE BATTERY DOOR WILL NOT CLOSE AND THE
UNIT WILL NOT ATTACH TO THE MOUNTING BRACKET.
Alignment marks are provided on the edge of the trim plate and the alarm. After installing the mounting
plate, place the alarm on the mounting plate with the alignment marks lined up. Twist the alarm in the
direction indicated by the "ON" arrow on the alarm cover (See Step D) until it locks in place.
FIGURE 4
USING TAMPER RESISTANT LOCKING PIN: To make your carbon monoxide alarm somewhat tamper
resistant, a locking pin has been provided in the bag with the screws and anchors. Using this pin will
deter children and others from removing the alarm from the mounting plate. To use the pin, insert it into
the hole in the side of the alarm after the alarm has been installed on the mounting plate (See Figure 5).
Note the tamper resistant pin will have to be removed in order to change the battery. This can be done
easily with long nose pliers. Using the long nose pliers, pull the pin out of the hole. It is now possible to
remove the alarm from the mounting plate.
FIGURE 5
Test alarm immediately following installation and weekly for proper operation by pushing the test
button approximately three seconds until a short beep is heard. Release the button. The alarm will then
test itself for proper operation and the red LED indicator will flash 4 times and the alarm will sound two
4 pulse patterns. The alarm then resumes normal operation.

NORMAL OPERATION
In normal operation, the alarm will flash the red LED indicator once every 30 seconds.
ALARM CONDITION
If the alarm senses unsafe levels of CO, the red LED indicator will light up and the alarm will sound. The
alarm condition will be signified by a repetitive alarm sounding pattern of 4 short beeps followed by 5
seconds of silence. Immediate evacuation is required. Pushing the test button will silence the alarm for
approximately 4 minutes. After approximately 4 minutes, the alarm will again sound until the unsafe CO
concentration is removed.
TROUBLE CONDITION
Periodically, the alarm's measurement circuit is tested. If an error is detected, the alarm will sound and
the red LED indicator will flash twice every 30 seconds. This is an indication of circuit malfunction and
that the alarm requires immediate servicing.
MAINTENANCE
BATTERY REPLACEMENT
IF THE TAMPER RESISTANT PIN HAS BEEN USED, REFER TO "TAMPER RESISTANT LOCKING
PIN" FOR REMOVAL INSTRUCTIONS (See Figure 5).
To replace the battery, remove the alarm from the mounting plate by rotating the alarm in the direction
of the "OFF" arrow on the cover (See Figure 4, Step D).
The CO alarm is powered by a 9V Alkaline battery. A fresh battery should last for one year under
normal operating conditions. This alarm has a low battery monitor circuit which will cause the alarm to
"chirp" and the red LED indicator to flash approximately every 30-40 seconds for a minimum of 7 days
when the battery gets low. Replace the battery when this condition occurs. USE ONLY THE FOLLOWING
9 VOLT BATTERIES FOR CO ALARM REPLACEMENT
Alkaline type:
Lithium type:
EVEREADY 522; DURACELL MN1604; GOLD PEAK 1604A
ULTRALIFE U9VL
NOTE: REGULAR TESTING IS RECOMMENDED.
WARNING! USE ONLY THE BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY HAVE
A DETRIMENTAL EFFECT ON THE CO ALARM. THE CONSTANT EXPOSURES TO HIGH OR
LOW TEMPERATURES OR HIGH HUMIDITY MAY REDUCE BATTERY LIFE.
CLEANING YOUR ALARM
To clean your alarm, remove it from the mounting plate as outlined in the beginning of this section.
You can clean the interior of your alarm by using your vacuum cleaner hose and vacuuming through the
openings around the perimeter of the alarm.
WARNING: The outside can be wiped with a damp cloth. Do not use any household cleaning agents,
ammonia based cleaners, paints, varnishes or any other chemical on or near your alarm. AFTER
CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM BY USING THE TEST BUTTON.
