4. INFORMATION ABOUT CARBON MONOXIDE
WHAT IS CARBON MONOXIDE?
Carbon monoxide (CO) is a highly toxic, invisible, odorless, tasteless gas.
HOW IS CO GENERATED IN THE HOME?
Carbon monoxide is generated through incomplete combustion of fuel in various home
appliances. Faulty ventilation of furnaces, water heaters, fireplaces, wood burning
stoves, and space heaters are the major cause of high CO levels in the home.
Automobile and small engine exhaust are another source of CO.
HOW DOES CO POISON PEOPLE?
The human body depends on oxygen for the burning of fuel (food) to provide us with the
energy that allows our cells to live and function. Oxygen makes up approximately 21%
of the atmosphere and enters our lungs when we breathe. In our lungs the oxygen
combines with the hemoglobin in the blood (oxyhemoglobin), and is carried in the blood
stream throughout the body where it releases oxygen to the cells.
Carbon monoxide is dangerous because it bonds more tightly to the hemoglobin
(carboxyhemoglobin, COHb) than oxygen does. When CO combines with hemoglobin,
the hemoglobin's ability to combine with oxygen is lost. As the COHb concentration
rises, people become nauseous, unconscious and ultimately die (see below).
WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE POISONING?
Many people often confuse carbon monoxide poisoning with the flu; the initial symptoms
being very similar. Different concentrations of CO over various lengths of time cause
different symptoms.
The following symptoms may be related to CARBON MONOXIDE POISONING and
should be discussed with ALL members of the household.
MILD EXPOSURE: Headaches, running nose, sore eyes, often described
as “flu”-like symptoms.
MEDIUM EXPOSURE: Dizziness, drowsiness, vomiting.
EXTREME EXPOSURE: Unconsciousness, brain damage, death
Many cases of CARBON
MONOXIDE POISONING
indicate that while victims
are aware they are not
well, they become so
disoriented that they are
unable to save
themselves by either
exiting the building or
calling for assistance.

5. RECOMMENDED LOCATION OF ALARMS
The Consumer Products Safety Commission (CPSC) recommends the use of "at least
one CO alarm per household located outside each sleeping area." (See diagrams "A"
and “B”).
CO poisoning can happen anywhere in the home, but because most CO poisoning
cases occur while people are sleeping, the best location for the CO alarm is near the
sleeping area in the home. If there is more than one sleeping area in the home or on a
different floor, or if bedroom doors are closed during the night, you may need more than
one CO alarm.
Carbon monoxide at room temperature [68
o
F (20°C)] is slightly lighter than air (density
of 0.96716). CO alarms should be mounted five feet off floor, or at eye level, for best
operation and to easily test alarm and view any display.
1. Locate the first alarm in the immediate area of the bedrooms. If more than one
sleeping area exists, locate additional alarms in each sleeping area.
2. Locate an alarm inside every room where someone sleeps with a door closed. The
closed door may prevent the alarm from waking the sleeper.
3. Locate an alarm on every level of the home. (See diagrams “A” and “B”)

6. LOCATIONS TO AVOID
NEAR THE COOKING AREA: Do not install the alarm within five feet of cooking
appliances. CO may be generated in the cooking process and cause nuisance alarms.
Also, cooking grease can build up on the alarm and cause alarm failure.
WITHIN FIVE FEET OF A FURNACE, WATER HEATER, OR SPACE HEATER:
These devices often spill out small amounts of CO when they first turn on.
IN GARAGES: Automobile exhaust contains CO and will activate alarm.
IN DUSTY AREAS: Dust can build up on alarm and prevent it from working properly.
IN CLEANING SUPPLY ROOMS: Chemicals used in household cleaning and painting
supplies may cause nuisance alarms.
IN UTILITY OR BATH ROOMS: Do not install the alarm inside or within three feet of a
room with a bathtub, shower, spa or washer/dryer. Excessive moisture may cause
nuisance alarms.
IN VERY HOT OR COLD AREAS: Do not install unit on any exterior wall or in areas
which are below 40
o
F (4.4°C) or above 100
o
F (37.8°C).
IN DEAD AIR SPACE: Do not install alarm within one foot of where wall meets ceiling
or floor.
IN HAZARDOUS LOCATIONS: This alarm is not suitable for installation in a
hazardous location, as defined in the National Electrical Code.
NEAR WIRELESS DEVICES: Do not install the alarm within one foot of wireless
devices. Radio Frequencies (RF) may interfere with the CO alarm’s proper operation.

8. FUNCTIONS AND OPERATION
OPERATION: The CO alarm is operational once the activation switch is slid to ON
position. The green LED will flash once every 30 seconds. The model CA6050 LCD
will also continuously display to indicate that the CO alarm’s power is active.
LOW BATTERY CONDITION: When the battery voltage drops below an acceptable
level, the alarm will chirp once per minute and the green LED will blink 5 seconds every
minute. The model CA6050 LCD will also display symbol. See Section 14 for
information regarding service.
SERVICE CONDITION: An internal microcontroller continuously monitors the sensor
function and other critical components. If an internal failure of any of these components
should occur, the alarm will chirp twice ( BEEP - BEEP ) per minute and the SERVICE red
LED will blink for 5 seconds every minute. The model CA6050 LCD will also
continuously display . This malfunction condition indicates a problem with the unit.
See Section 14 for information regarding service.
END-OF-LIFE CONDITION: The electrochemical sensor has a minimum five year life
expectancy. Once the battery is activated, a microcontroller monitors the total time that
the alarm is under power. After five years of service, the “End-of-Life” signal will be
activated; the alarm will chirp once per minute and the SERVICE red LED will glow for 3
seconds at the same time. The model CA6050 LCD will also continuously display
to indicate that the sensor life has expired and the alarm should be replaced. See
Section 14 for handling an End-of-Life alarm.
ALARM CONDITION: When the batteries are active, and CO gas is detected at a level
and duration specified in Section 3 CO RESPONSE TIMES, the horn will sound and the
ALARM red LED will light. The alarm signal will sound 4 short beeps every 6 seconds.
The ALARM red LED will flash in sync with the beeping sound. The model CA6050 LCD
will also display the current CO Level detected. After having alarmed for more than 5
minutes, the alarm signal will change to 4 short beeps every 60 seconds. The alarm
signal is either manually or automatically reset. See Section 10 WHAT TO DO WHEN
THE ALARM SOUNDS.
TEST/RESET/MUTE BUTTON: The TEST/RESET/MUTE button is used to check the
alarm for proper operation, and to temporarily mute horn for 5 minutes when alarm is
activated, for 24 hrs. during the first week of a “Low Battery Voltage” signal ( )
activation, or for 60 hrs. during the first month of an “End-of-Life” signal ( )
activation. The model CA6050 LCD will display the current CO level detected when
alarm is being tested, or when an alarm signal is muted. See Section 9 for Testing
procedure.
LCD DISPLAY FUNCTION (FOR MODEL CA6050): When alarm is operating
normally, the LCD will continuously display . If room temperature exceeds 120°F
(48°C), the LCD will display for 5 seconds every minute. If a CO level of 30 ppm or
more is detected, or alarm is activated, the LCD will automatically display the current
CO level detected. The LCD will display the symbol if the battery has low voltage.

30 days, the alarm will return to its normal “End-of-Life” condition; 1 chirp per minute,
SERVICE red LED glows for 5 seconds at the same time, and model CA6050
continuously displays “End”.
To test your alarm during an “End-of-Life” condition, press and hold TEST/RESET/MUTE
button for minimum 2 seconds when audible signal is not sounding.
The audible signal cannot be muted when alarm is in SERVICE condition; chirps twice
( BEEP - BEEP ) per minute, SERVICE red LED blinks for 5 seconds, and model CA6050
continuously displays . See Section 14 for information regarding service.
10.WHAT TO DO WHEN THE ALARM SOUNDS
If alarm signal sounds:
1) Operate test/reset/mute button;
2) Call your emergency services (tel. no. _______________________________)
[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/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 your alarm reactivates within a 24 hour period,
repeat steps 1-3 and call a qualified appliance technician (tel. no.
________________________________) to investigate for sources of CO from
fuel burning equipment and appliances, and inspect for proper operation of
this equipment. If problems are identified during this inspection, have the
equipment serviced immediately. Note any combustion equipment not
inspected by the technician and consult the manufacturers' instructions, or
contact the manufacturers directly, for more information about CO safety
and this equipment. Make sure that motor vehicles are not, and have not
been, operating in an attached garage or adjacent to the residence.
MANUAL RESET: You can temporarily silence an audible alarm signal by pressing the
TEST/RESET/MUTE button. The ALARM red LED will flash 4 times, and the model
CA6050 will display for 5 seconds and then continue to display the current CO
level detected from 30 to 999 ppm. If 70 ppm or more continues to be detected, the
audible and visual alarm signals will be automatically reactivated within 5 minutes. Do
not wait to see if the alarm is reactivated; follow above instructions immediately.
AUTOMATIC RESET: If a CO alarm activation is not manually reset, the horn will
sound for at least 5 minutes. After 5 minutes, the alarm will automatically reset itself
and return to normal operation if the CO which caused the alarm activation has cleared.

- 13 -
IF YOU HAVE BEEN AWAY FROM HOME and you return to find your alarm(s)
sounding, DO NOT ENTER YOUR HOME. Call the Fire Department from a
neighbor's home. DO NOT RE-ENTER YOUR HOME FOR ANY REASON UNTIL
YOU HAVE BEEN ASSURED THAT IT IS SAFE TO DO SO.
Conditions which can result in transient CO situations:
1) Excessive spillage or reverse venting of fuel burning appliances caused by
outdoor ambient conditions, such as:
i) Wind direction and/or velocity, including high gusts of wind. Heavy air in
the vent pipes (cold/humid air with extended periods between cycles).
ii) Negative pressure differential resulting from the use of exhaust fans.
iii) Simultaneous operation of several fuel burning appliances competing for
limited internal air.
iv) Vent pipe connections vibrating loose from clothes dryers, furnaces, or
water heaters.
v) Obstructions in or unconventional vent pipe designs which can amplify
the above situations.
vi) Poorly designed or maintained chimneys and/or vents.
2) Extended operation of unvented fuel burning devices (range, oven, etc.).
3) Temperature inversions which can trap exhaust gases near the ground.
4) Car idling in an open or closed attached garage, or near a home.
If SERVICE or low battery signals are activated, see Section 14 for service and
return instructions.
11.LIMITATIONS OF CARBON MONOXIDE ALARMS
Carbon monoxide alarms respond to the presence of CO. They do not detect smoke. If
the alarm does activate, follow instructions in Section 10 WHAT TO DO WHEN THE
ALARM SOUNDS.
Carbon monoxide alarms are devices that can provide an early warning of the presence
of CO gas at a reasonable cost. However, alarms have sensing limitations and may not
always sound a warning in the presence of CO. The alarm will not operate if the battery
power is low or dead. CO alarms must be tested regularly to ensure that they are
receiving power and operating properly. Carbon monoxide alarms cannot sense CO
that does not reach the alarm, and therefore CO alarms may not detect CO which is in
another area of the home. Furthermore, if the alarm is located on a different level of the
home, or on the other side of a closed door, it may not waken a sound sleeper. The use
of drugs and alcohol may impair ones ability to hear the alarm. If you have a multi-level
home, install CO alarms on each level of the home. If the alarm is installed in a hallway
and the bedroom doors are kept closed at night, install a CO alarm within each
bedroom.
Although CO alarms can help save lives by providing an early warning to the presence
of carbon monoxide, they are not a substitute for an insurance policy. Homeowners and
renters should have adequate insurance to protect their health, lives and property.

- 14 -
12.GOOD SAFETY HABITS
DEVELOP AND PRACTICE A PLAN OF ESCAPE:
Make a floor plan indicating all doors and windows and at least two escape routes from
each room. Second story windows may need a rope or chain ladder.
Have a family meeting to discuss your escape plan, and show everyone what to do in
case an alarm sounds.
Determine a place outside your home where you can all meet if an alarm sounds.
Familiarize everyone with the sound of the alarm and train them to leave the home
when they hear it.
Practice a CO fire drill at least once every six months. Practice allows you to test your
plan before an emergency. You may not be able to reach your children. It is important
that they know what to do.
Discuss the symptoms related to CARBON MONOXIDE POISONING with all members
of the household. (See Section 4 WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE
POISONING?)
