CARBON MONOXIDE ALARM
MODEL CD-9690
(WITH DISPLAY)
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 and should be
discussed with ALL members of the household:
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.
This alarm will only indicate the presence of carbon monoxide gas surrounding its sensor.
Carbon monoxide gas may be present in other areas.
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.
Two self-adhesive labels have been provided with instructions indicating what to do if the
alarm sounds. Add the phone numbers of your emergency services provider and a qualified
technician to each label. Place one of the labels in a visible area next to the alarm and
place the other label near a source of fresh air which will be used as a gathering place if the
alarm sounds.
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.

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 1 foot (.3m) from fluorescent lights. Electronic noise may cause false alarms.
– Within 5 feet (1.5m) of any cooking appliance.
– Closer than 20 feet (6m) away from a furnace or other fuel burning heat source or
fuel burning appliances such as a water heater.
– Near an open window or door, because the fresh air entering the opening may
delay CO from reaching the alarm.
– In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or
shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other
source of high humidity.
– 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 to 100oF (4.4o to 37.8oC).
– In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air
returns or open windows. Blowing air may prevent CO from reaching the sensors.
– 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.

INSTALLATION AND OPERATION
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
Leave your CO alarm plugged in year-round. CO problems can occur any time
during the year and this alarm can only alert you if it is plugged in and receiving
power.
This CO alarm is intended for use in a standard, unswitched 120VAC wall outlet. It is
not intended for use in extension cords, power strips or outlets controlled by a switch
or dimmer. These may not provide continuous power to the unit. When fully powered,
it samples the air continuously. A microchip inside the unit stores each reading and
remembers the levels of CO it has been exposed to over time. The unit goes into
alarm mode when it has been exposed to a "critical" level of CO (measured in parts
per million or "ppm") within a specified time (measured in minutes).
PLUG THE ALARM INTO AN OUTLET
120 VAC, 60 Hz, 100 mA
This unit should receive continuous electrical power. (The battery is meant for
emergency backup only.) Choose an outlet where it can't be accidentally
unplugged or switched off by children. Keep small children away from the unit.
Teach them not to play with it or unplug it. Explain what the alarms mean.
Do not plug this alarm into an outlet controlled by a dimmer or switch or ground
fault circuit interrupter.
1. Plug the unit into a standard UNSWITCHED 120VAC outlet. The unit should be
located where it can wake you if it alarms at night.
2. Make sure the green power "ON" LED is on continuously when you plug it in. The
horn will "chirp" during power up or when power is restored after an outage.
Test alarm immediately following installation and weekly for proper operation by
pushing the test button. The alarm will then test itself for proper operation and the red
LED indicator will flash on two 4-pulse patterns and the alarm will simultaneously
sound two 4-pulse patterns. The alarm then resumes normal operation. The Display
will show the highest reading in memory and then three dashes (Model CD-9690).
OPERATION, TESTING & MAINTENANCE
OPERATION: The alarm is operating once the power is connected. When CO gas is
sensed at a high level or at a low level for a lengthy period of time, the unit sounds a
loud alarm which continues until the air is cleared, or the alarm is reset.
If the local alarm is self-cleared, i.e. the carbon monoxide level returns to normal, the
green LED flashes off and on until manually reset.
TESTING YOUR ALARM: Test alarm monthly for proper operation by pushing the
test button. Release the button. The green LED will go off and the yellow LED will
come on. The alarm will then test itself for proper operation and the red LED will flash
on two 4-pulse patterns and the alarm will simultaneously sound two 4-pulse patterns.
The alarm then resumes normal operation. The Display will show the highest reading
in memory and then three dashes (Model CD-9690).
STANDBY CONDITION: The green LED is on and blinks off approximately every 20
seconds whenever AC power is turned on. The Display will only indicate CO readings
higher than 30ppm (Model CD-9690).
ALARM CONDITION: The red LED flashes on and the unit emits a loud, pulsating
alarm (4 short beeps, pause/4 short beeps, pause, until reset). The Display will show
the current CO reading (Model CD-9690).

NORMAL OPERATION
In normal operation, the alarm will blink the green LED off once approximately every
20 seconds. The display will indicate the current CO readings (if higher than 30ppm)
or three dashes (Model CD-9690).
SERVICE/TROUBLE CONDITION
Periodically, the alarm's measurement circuit is tested. If an error is detected, the
alarm will sound a double "beep" and the yellow LED will flash on twice approximately
every 40 seconds. This is an indication of circuit malfunction and that the alarm required
immediate servicing.
When AC power is lost, the green LED is off.
IF THE ALARM SOUNDS:
1. Operate the Test/Reset button to silence the alarm.
(Phone No.
)
2. Call your emergency services, fire department or 911;
3. Immediately move to fresh air - outdoors or by an open door or window. Do a head
count to check that all persons are accounted for. Do not re-enter the premises or
move away from the open door or window until the emergency services responder
has arrived, the premises have been aired out and your CO alarm remains in its
normal condition.
4. After following steps 1-3, if your CO alarm reactivates within a 24-hour period,
repeat steps 1-3 and call a qualified appliance technician to investigate for sources
of CO from fuel-burning equipment and appliances and inspect for proper operation
of this equipment.
If the Display Shows
30 (or higher)
It Means
Developing CO problem. The display will only show levels or
carbon monoxide 30 ppm or higher.
70 (or higher)
150 (or higher)
The unit is calibrated to sound an alarm before 240 minutes
have passed when exposed to this level.
The unit is calibrated to sound an alarm before 50 minutes
have passed when exposed to this level. At this level, an
average healthy adult may feel headache within 90 minutes.
400 (or higher)
The unit is calibrated to sound an alarm before 15 minutes
have passed when exposed to this level. This level may be
life threatening to a normal healthy adult within three hours.
A number higher
than 450
Over 450 ppm of CO has been detected. Evacuate
immediately!
CLEANING YOUR ALARM
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.
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.

MAINTENANCE
BATTERY REPLACEMENT
The CO alarm is powered (backup) by a 9V 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 sound a short "beep" approximately every 40 seconds,
for a minimum of 7 days, when the battery gets low. Replace the battery when this
condition occurs, by using the QUICK DRAWTM pull-out battery drawer for easy
replacement.
Slide the QUICK DRAWTM pull-out battery drawer out. While observing polarity, push
the replacement battery into the battery drawer until it is held securely in place. Carefully
close and latch the QUICK DRAWTM pull-out battery drawer.
USE ONLY THE FOLLOWING 9 VOLT BATTERIES FOR CO ALARM
REPLACEMENT
Alkaline type:
Lithium type:
EVEREADY 522; DURACELL MN1604
ULTRALIFE U9VL-J
NOTE: REGULAR TESTING IS RECOMMENDED.
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.
IMPORTANT!
The battery backup is designed to provide short-term emergency power to the CO
alarm. Actual backup time depends on the strength (freshness) of the battery. The
battery backup will not work unless a good battery is properly installed.
