About this Smoke/Carbon Monoxide Alarm:
This combination Smoke/CO alarm is designed to detect smoke and carbon monox-
ide gas. It is NOT designed to detect fire or any other type of gas. If this Smoke/CO
alarm sounds its alarm horn, DO NOT assume that it is a false alarm. The alarm
horn requires your immediate action.
WARNING
Individuals with medical problems may consider using warning devices which provide
audible and visual signals for carbon monoxide concentrations under 30ppm.
SPECIFICATIONS AND IMPORTANT PRODUCT INFORMATION
Product Features
•Monthly Self-Test: Approximately every 30 days this alarm performs a silent
internal system test to verify sensor operation utilizing True Gas Testing. True
Gas Testing verifies that the CO sensor is nearing the end of its service life.
Traditional CO alarms test the sensor by simulating an alarm condition electrically.
This is the first CO sensor that runs a diagnostic test by generating a very small
and harmless amount of hydrogen gas. If the sensor is working properly, it WILL
NOT chirp. If the alarm chirps during the monthly self-testing, it is indicating a
problem with the unit. Refer to the charts on pages 6 and 7 for the appropriate
actions to take should this occur. You must still test the alarm weekly to verify
proper horn operation.
•Trigger Alarm Locator™ (TAL™): Most interconnect tests trigger all alarm horns
simultaneously for the duration of the test. This unique system alternates between
a 10 second ALL ON cycle and a 50 second cycle where only the initiating alarm
is sounding.
•Alarm Controlled Interconnect Test: In an interconnected system, this feature
will alarm the local unit first, then quiet the local unit while the remote units alarm.
•Smart Quiet™ Low Battery 1: Allows the homeowners to silence the low battery
chirp for up to 10 hours, giving them time to go back to sleep and/or purchase a
fresh replacement battery.
•Smart Quiet™ Low Battery 2: Indicates the battery no longer has enough volt-
age to adequately protect in the event of a power outage or a battery-only instal-
lation. The Smart Quiet™ feature will no longer silence the chirp. THE BATTERY
MUST BE REPLACED IMMEDIATELY.
Required Power Supply
• Model FADCM requires constant 120-volt, AC power AND/OR a working 9-volt battery
to operate properly. The alarms WILL NOT work if AC power is not connected or has
failed or been interrupted for any reason (AND in the case of FADCM and FADCM-B,
the battery is removed, drained or improperly connected). DO NOT use any other kind
of battery except as specified in this manual.
• Model GCM requires constant 120-volt AC power to operate properly.
• You may operate Models FADCM and FADCM-B on battery power only. Having only
one source of power is less reliable than having two different power sources. If the bat-
tery is too weak to power the alarm, or is removed from the alarm, the alarm will not
protect you from hazardous conditions within your home. Make sure a battery-only
installation complies with your local codes and regulations. Check with your local fire
department or building code enforcement department if you are unsure of rules.
NOTE: AC/DC alarms offer added protection in the event of a power failure or a
drained battery.

AGENCY ALARM PLACEMENT RECOMMENDATIONS
Invensys Controls Americas recommends complete coverage protection achieved by
installing a smoke alarm in every room of your home.
The National Fire Protection Association’s (NFPA) minimum
requirement, as stated in Standard 72, Chapter 2, reads as follows:
“2-2.1.1.1 Smoke detectors shall be installed
outside of each separate sleeping area in the
immediate vicinity of the bedrooms and on
each additional story of the family living unit
including basements and excluding crawl
spaces and unfinished attics. In new construc-
tion a smoke detector also shall be
installed in each sleeping room.”
Chapter 2 also reads as follows:
“2-2.2.1 In new construction, where more than one smoke detector is required by 2-
2.1, they shall be so arranged that operation of any smoke detector shall cause the
alarm in all smoke detectors within the dwelling to sound.”
“2.5.2.1 The required number of smoke detectors might not provide reliable early
warning protection for those areas separated by a door from the areas protected by
the required smoke detectors. For this reason it is recommended that the household-
er consider the use of additional smoke detectors for those areas for increased pro-
tection. The additional areas include the basement, bedrooms, dining room, furnace
room, utility room and hallways not protected by the required smoke detectors. The
installation of smoke detectors in kitchens, attics (finished or unfinished), or garages
is not normally recommended, as these locations occasionally experience conditions
that can result in improper operation.”
This equipment should be installed in accordance with the National Fire Protection
Association’s Standard 72, NFPA, Batterymarch Park, Quincy, MA 02269.
THIS STANDARD MEANS YOU SHOULD INSTALL AND USE A SMOKE ALARM IN
EVERY ROOM AND AREA OF YOUR HOUSEHOLD OR
BUILDING FOR BEST PROTECTION.
The NFPA, 1993 Edition, Appendix A further states:
“The required number of smoke detectors may not provide reliable early warning
protection for those areas separated by a door from the areas protected by the
required smoke detectors. For this reason, it is recommended that the house holder
consider the use of additional smoke detectors for those areas for increased protec-
tion. The additional areas include: basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the required smoke detectors.”
Also, as required by the California State Fire Marshal:
“Early warning fire detection is best achieved by the installation of fire detection
equipment in all rooms and areas of the household as follows: a smoke detector
installed in each separate sleeping area (in the vicinity, but outside the bedrooms),
and heat or smoke detectors in the living rooms, dining rooms, bedrooms, kitchens,
hallways, attics, furnace rooms, closets, utility and storage rooms, basements and
attached garages.
Important Smoke Alarm Placement
and Exception Information
• Install a smoke alarm as close to the center of the
ceiling as possible. If this is not practical, mount no
closer than 4 inches from a wall or corner. Also, if
local codes allow, install smoke alarms on walls,
between 4 and 12 inches from ceiling/wall
intersections.
• Install a minimum of two smoke alarms in every
home, no matter how small the home. New con-
struction codes require a minimum of two intercon-
nected smoke alarms in newly built homes.
• Install a smoke alarm in each room that is divided by a partial wall (either coming
down from the ceiling at least 24 inches, or coming up from the floor).
• Install smoke alarms on peaked, cathedral, or gabled ceilings 3 feet from the
highest point (measured horizontally).
• Install a smoke alarm in lived-in attics or attics which house electrical equipment
like furnaces, air conditioners, or heaters.

For best protection, install a smoke alarm in EVERY room. In addition, we recom-
mend that all smoke alarms be interconnected.
Different Types of Smoke Alarms
Ionization alarms are generally more effective at detecting fast, flaming fires that
consume combustible materials rapidly and spread quickly. Sources of these fires
may include flammable liquids or paper burning in a waste container.
Photoelectric alarms are generally more effective at detecting slow, smoldering
fires that smolder for hours before bursting into flame. Sources of these fires may
include cigaretts burning in couches or bedding. However, both types of
alarms provide adequate detection of both types of fires.
If you desire the earliest detction of both smoldering fires and fast flaming fires,
you should install smoke alarms that combine both photoelectric and ionization
sensing technologies in one unit.

For Optimal Performance, Avoid Installing Smoke Alarms
in the Following Locations:
• Near appliances or areas where normal combustion regularly occurs (kitchens, near
furnaces, hot water heaters). Use specialized smoke alarms with Quick Quiet™
False Alarm Control™ alarm control for these areas.
• In areas with high humidity, (bathrooms or areas near dishwashers or washing
machines) install at least 10 feet (3 meters) away from these areas, if possible.
• Near air returns or within 3 feet (1 meter) of heating and cooling supply vents.
The air could blow smoke away from the detector, interrupting its alarm.
• In rooms where temperatures may fall below 40°F (4°C) or rise above 100°F (38°C).
• In extremely dusty, dirty, or insect-infested areas. Loose particles interfere with
smoke alarm operation.
• Within 3 feet (1 meter) of fluorescent lighting. Electrical noise may cause nuisance
alarms.
WARNING
DO NOT install Smoke/CO alarms:
• Near bathrooms or in shower areas. Steam and aerosol sprays can disable
the alarm.
• In closets, crawlspaces, unused attics, or unheated areas where surrounding air
temperatures man go below 40ºF (4.4ºC) or above 100ºF (37.8ºC).
• Within five feet of any fuel-burning appliance (stove, kerosene heater, furnace,
fireplace, etc.).
• Within one foot of any wall, corner, or other dead air space.
• In rooms where chemicals or cleaning supplies are frequently used (paint,
hair spray, thinner, etc.). Allow plenty of ventilation in rooms where chemicals
are used.
• Directly above a sink, bathtub or basin.
• Directly above or below air exchange or heating vents.
• Behind drapes, furniture, or appliances that could block air flow to the alarm.
WARNING
This unit cannot be used in recreational vehicle applications.
Limitations of This Smoke/CO Alarm
• Smoke and CO alarms may not alert every household member every time. The alarm
horn is loud in order to alert individuals to a potential danger. However, there may be
limiting circumstances where a household member may not hear the alarm (e.g. out-
door or indoor noise, sound sleepers, drug or alcohol usage, the hard of hearing,
etc.). If you suspect that this alarm may not alert a household member, install and
maintain specialty smoke alarms. Household members must hear the alarm’s warning
sound and quickly respond to it to reduce the risk of damage, injury, or death that
may result from fire. If a household member is hard of hearing, install special alarms
with lights or vibrating devices to alert occupants.
• Smoke alarms can only sound their alarms when they detect smoke. Smoke alarms
detect combustion particles in the air. They do not sense heat, flame, or gas. This
alarm is designed to give audible warning of a developing fire. However, many fires
are fast-burning, explosive, or intentional. Others are caused by carelessness or safe-
ty hazards. Smoke may not reach the smoke alarm QUICKLY ENOUGH to ensure
safe escape.
• Smoke alarms must not be used with detector guards unless the combination of
alarm and guard has been evaluated and found suitable for that purpose.
• CO alarms can only sound their alarms when they detect CO gas. They do not sense
heat, flame, or any gas other than carbon monoxide (CO). This alarm is designed to
give audible warning that a dangerously high level of CO is present. You must
respond immediately to the CO alarm horn.
• Smoke and CO alarms have limitations. This alarm is not foolproof and is not war-
ranted to protect lives or property from fire. Smoke and CO alarms are not a substi-
tute for insurance. Homeowners and renters should insure their lives and property. In
addition, it is possible for the alarm to fail at any time. For this reason, you must test
the alarm weekly and replace every 5 years.
Under Normal Operation
• DO NOT remove or disconnect the battery or turn off AC power to quiet unwanted
alarms. This will remove your protection. This alarm features a Quick Quiet™
False Alarm Control™ button which, when activated, will quiet unwanted smoke
or CO alarms for up to 6 minutes.
Installation/Interconnect
•It is important to note that this smoke/CO combination alarm IS NOT com-
patible with models FADCQ and COQ8. If more than one model FADCQ, or
more than one model COQ8, is in your home, all must be replaced in order to
achieve a fully operational interconnected system. If models FADCQ and
COQ8 are interconnected with this combination alarm, they will operate as if
they were single station stand-alone alarms, thus eliminating the benefits
and additional protection of an interconnected system.
Models FADCQ and COQ8 are still compatible with all existing Firex AC and
AC/DC smoke alarms.
• This Smoke/CO alarm should be installed only by a licensed qualified electrician.
Observe and follow all local and national electrical and building codes for
installation.
• Unique power connector prevents interconnection with incompatible smoke and
combination alarms or security systems.
• This combination alarm may be interconnected with as many as 11 other Firex
model COE, COEA, FADCM, FADCM-B, GCM, FADC, TPCI, AD, ADC, PAD,
FPAD, G, GC, or PG40 smoke alarms, and as many as 6 Firex model ADH heat
alarms and/or CO alarms for a total of not more than 18 interconnected devices.
About Locating CO Alarms
Carbon monoxide gas can be anywhere and everywhere. CO gas is equal to or
slightly lighter than air, and disperses evenly with the air in a room. Therefore,
install this CO alarm where air circulation is best. Since most CO fatalities occur
while families are sleeping, we recommend that you install at least one CO alarm
in the hallway outside each separate sleeping area and one inside each bedroom
or sleeping area.
We also recommend that you install a CO alarm on every separate living level of
the home where household members frequently spend time, as well as in the
basement.
This CO alarm can share the interconnect wire of smoke and heat alarms,
BUT this alarm will remain silent if smoke or high heat is detected by the
interconnected smoke and heat alarms. Therefore it is necessary to install
both a CO alarm and smoke alarm or a smoke/CO combination alarm in
those areas to be fully protected.
CAUTION
This alarm will indicate only the presence of carbon monoxide gas at the
sensor. Carbon monoxide gas may be present in other areas.

• You may use the multiple station interconnected features of your combination
alarm even if powered only by a battery. We recommend that you check with your
local code enforcement bureau before mixing interconnected alarm devices that
may be normally operating both with and without AC power.
• This alarm can share the interconnect wire of smoke and heat alarms. The alarm
will automatically sound a smoke alarm signal if smoke is detected by this unit or
any other interconnected smoke alarm, even if the unit is already detecting carbon
monoxide and sounding the carbon monoxide alarm signal.
WARNING
• DO NOT connect this Smoke/CO alarm to any other type of smoke, CO, heat,
or combination alarm or auxiliary device except those listed in this manual.
• WHILE AC AND AC/DC SMOKE, CO AND HEAT ALARMS CAN BE INTERCON-
NECTED, ONLY WHEN AC POWER IS ACTIVE WILL ALL UNITS ALARM WHEN
ONE UNIT SENSES A HAZARDOUS CONDITION. WHEN AC POWER IS DIS-
CONNECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, ONLY
AC/DC UNITS WILL CONTINUE TO SEND AND RECEIVE SIGNALS AND SOUND
AN ALARM IN RESPONSE TO THE PRESENCE OF SMOKE. WHEN POWER IS
DISCONNECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, AC
POWERED SMOKE, CO, OR HEAT ALARMS WILL NOT OPERATE!
Compliance and Proper Applications
• This Smoke/CO alarm is designed to be used inside a single-family household. In
multi-family buildings, each individual living unit should have its own alarms. It is
not a substitute for a complete commercial alarm system. It should be used only
as supplemental protection in hotels, motels, dormitories, hospitals, nursing
homes, or group homes.
• 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.
NOTE: Enclosed with this Smoke/CO alarm are two labels detailing actions to
take in the event of an alarm. One should be placed next to the Smoke/CO
alarm; the other should be placed near a source of fresh air. Please provide the
telephone number of the emergency provider and a qualified technician on each
label.
HOW TO INSTALL THIS SMOKE/CO ALARM

• You may use the multiple station interconnected features of your FADCM even if
powered only by a battery. We recommend that you check with your local code
enforcement bureau before mixing interconnected alarm devices that may be
normally operating both with and without AC power.
• This alarm can share the interconnect wire of smoke and heat alarms. The alarm
will automatically sound a smoke alarm signal if smoke is detected by this unit or
any other interconnected smoke alarm, even if the unit is already detecting carbon
monoxide and sounding the carbon monoxide alarm signal..
WARNING
WHILE AC AND AC/DC SMOKE, CO AND HEAT ALARMS CAN BE INTERCON-
NECTED, ONLY WHEN AC POWER IS ACTIVE WILL ALL UNITS ALARM WHEN
ONE UNIT SENSES A HAZARDOUS CONDITION. WHEN AC POWER IS DISCON-
NECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, ONLY AC/DC
UNITS WILL CONTINUE TO SEND AND RECEIVE SIGNALS AND SOUND AN
ALARM IN RESPONSE TO THE PRESENCE OF SMOKE, CO, OR HEAT, AS
DETERMINED BY THE MODEL OF ALARM THAT IS PRESENT. WHEN POWER IS
DISCONNECTED, INTERRUPTED OR NOT PRESENT FOR ANY REASON, AC
POWERED SMOKE, CO, OR HEAT ALARMS WILL NOT OPERATE.
THIS ALARM SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL
FIRE PROTECTION ASSOCIATION’S STANDARD 72 (National Fire Protection
Association, One Batterymarch Park, Quincy, MA 02269).
• Connect CO and smoke alarms to a single dedicated AC branch circuit. If local
codes do not permit such a wiring configuration or connection, be sure the neutral
wire is common to both circuits or phases.
Installing AC/DC Smoke/CO Alarms as Replacements
with Interconnected Legacy Firex Alarms
Model FADCM and GCM combination alarms are designed to be used as replace-
ment units for most Firex AC and AC/DC smoke alarms with a low voltage intercon-
nect line. These models include G, GC, H, AD, ADC, and FADC. All models listed use
a 3-wire interconnect system. To interconnect with other Firex models, please call our
free technical support line at [phone].
IMPORTANT! READ BEFORE INSTALLING THIS SMOKE/CO ALARM WITH
EXISTING INTERCONNECTED FIREX ALARMS
In residential homes, there are two ways smoke and Smoke/CO alarms are hardwire
installed and interconnected. One uses 4 wires, the other uses 3 wires.
The model
FADCM and GCM alarms can be used with both 4 and 3 wire systems.
1. Identify whether the installed system uses 3 or 4 wires to interconnect.
2. If a 4-wire system is installed, change the system to a 3-wire by connecting the
independent interconnect wires (yellow and blue) at any point in the system.
3. Smoke alarms generally don’t require any changes (other than replacement every
ten years).
4. Replace older Smoke/CO alarms on the new 3-wire system with FADCM and GCM
Smoke/CO alarms. These alarms can discriminate between signals coming from a
smoke alarm and signals coming from a CO alarm. Older model Smoke/CO alarms
converted to 3-wire cannot. So when any alarm is triggered, all the older CO
alarms will sound, creating confusion about which danger is actually present.
To Install a Combination Unit as a Replacement:
1. Turn off AC power at circuit breaker or main fuse box.
2. Remove old alarm from mounting bracket.
3. Disconnect wire connector from back of unit.
4. Remove wire nuts and connect new wire connector to household wiring. Be cer-
tain not to cross the wiring.
5. Connect wire connector to back of alarm.
6. If mounting bracket is the same, reattach alarm to mounting bracket. Feed wiring
back through hole in mounting surface.
7. Turn on power at main fuse box or circuit breaker.
8. Test Smoke/CO alarm. See “TESTING THE SMOKE/CO ALARM.”
9. Model FADCM AC/DC model only: Activate the battery. Remove arrow tab and
close battery yellow light will flash as door is closed.
CAUTION
Do not use super glue or silicon caulk on or near the alarm! Fumes from
these products can coat and permanently damage the sensor.

IF THE ALARM SOUNDS
If Your Smoke Alarm Sounds (and you are not testing it)
WARNING
IF BOTH RED LIGHTS ARE FLASHING AND THE HORN SOUNDS 3 ALARMS
APPROXIMATELY EVERY FOUR SECONDS, IT INDICATES THE PRESENCE OF
SMOKE WHICH CAN INDICATE THE PRESENCE OF FIRE.
YOU MUST QUICKLY DO THE FOLLOWING:
1. Don’t panic; stay calm.
2. Leave the building as quickly as possible. Touch doors with the back of your hand
to feel if they are hot before opening them. IF DOOR IS HOT USE AN ALTERNATE
EXIT. Crawl along the floor, and DO NOT stop to collect anything.
3. Meet at a pre-arranged meeting place outside the building.
4. Call the fire department from OUTSIDE the building.
5. DO NOT GO BACK INSIDE A BURNING BUILDING.
If Your CO Alarm Sounds (and you are not testing it)
Carbon Monoxide has no taste, feel or smell – but it can be FATAL.
WARNING
IF 1 RED LIGHT IS FLASHING AND THE HORN SOUNDS 4 ALARMS APPROXI-
MATELY EVERY FIVE SECONDS, IT INDICATES THE PRESENCE OF CO WHICH
CAN BE FATAL. YOU MUST QUICKLY DO THE FOLLOWING:
1. Operate Test/Reset button;
2. Call your emergency services [fire department or 911]
3. Immediately move to fresh air — outdoors or by an open door/window. Make cer-
tain that all persons are accounted for. Do not reenter 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 (__________________) to inves-
tigate sources of CO from fuel burning equipment and appliances, and to inspect
for proper operation of this equipment. If problems are identified during this
inspection, have the equipment serviced immediately. Note any combustion equip-
ment 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, operat-
ing in an attached garage or adjacent to the residence.
If the CO alarm sounds its alarm horn again, it has sensed CO. This is not a
false alarm.
TO TEMPORARILY SILENCE AN ALARM
NOTE: These features temporarily quiet alarms, but do not disable the sensor.
When you push the Smart Button during an alarm,
one of three things will happen:
1. All interconnected alarms are
silenced. This means you pushed
the button on the unit that actually
triggered alarm. (Quick Quiet“ False
Alarm Control“)
2. One unit still sounding an alarm;
the rest are silenced. The unit that
triggered alarm continues to sound
so you can identify the remote source
of the alarm. (Smart Quiet“ Trigger
Alarm Locator)
3. The unit whose Smart Button you
pressed is still sounding an alarm;
the rest are silenced. This indicates
an immediate danger. Smoke or CO is
intense enough to override the silence
option.
Quick Quiet™CO Reset
Smart Quiet™Trigger Alarm Locator
These features help you identify the trigger alarm(s) and areas of immediate
danger to avoid under alarm conditions. After one minute if a dangerous condition per-
sists all units will go back into alarm: all alarms will sound for 10 seconds, then just the
initiating alarm will sound for 50 seconds. This 10-second/50-second alarm pattern
will keep repeating until the air is cleared and the immediate danger has

IMPORTANT SAFETY INFORMATION
Fire Safety Tips
These guidelines will assist you in the event of a fire. However, to reduce the chance
that fires will start, practice fire safety rules and prevent hazardous situations.
• Develop family escape plans, discuss them with ALL household members, and
practice them regularly. The plans should include TWO exits from each room, an
escape route to the outside from each exit, and a safe meeting place for everyone
outside the building.
• Familiarize everyone with the sound of a smoke alarm and explain what it means.
• Teach all household members NOT TO OPEN ANY DOOR IF THE DOOR IS HOT,
and to crawl along the floor to stay below dangerous smoke, fumes, and gases.
CO Home Safety Tips
CO poisoning is often caused by equipment failures due to poor maintenance,
product defects, and damaged parts. The following tips can help prevent CO
within your home:
1. Have all fuel-burning appliances inspected and cleaned yearly by a qualified serv-
ice technician. The furnace, water heater, and stove are some of the
leading sources of CO.
2. Clean fireplace vents and chimney regularly. A blocked chimney could cause
a backdraft of CO into the home. Do not seal chimney. This will cause a
backdraft of CO into the home.
3. Do not seal a draft hood or exhaust vent to any appliance. This will trap
dangerous CO inside the house.
4. Do not close off or confine your fuel-burning appliances in a closed area.
They need plenty of ventilation to operate properly.
5. Do not use liquid propane (LP) or charcoal grills or operate any gasoline
powered equipment indoors.
6. Allow for plenty of ventilation when using a kerosene heater. Do not use in
small areas.
Preventive maintenance, common sense, and a CO detection device are some of the
best methods of preventing CO poisoning. However, a dangerous situation can hap-
pen to anyone at any time.
The following list illustrates some danger signs of CO presence.
1. Soot and dirt build-up seeping out of chimney or other exhaust vents.
2. A mostly yellow (rather than clear blue) burner flame or pilot flame in gas
appliances.
3. A draft of air coming from an appliance, chimney, or vents.
4. Car idling in an open or closed attached garage, or near a home.
If you have flu-like symptoms or suspect CO poisoning, seek medical
assistance immediately!
Symptoms of Carbon Monoxide Poisoning
CO poisoning has many symptoms. Some are very similar to the flu, the effects
of intoxication, or drug usage. In many CO cases, people feel ill and stay home to rest.
This only compounds the CO poisoning because they stay in the home where CO is
present.
As CO levels rise, the symptoms become more extreme. At low levels people will
suffer headaches and mild nausea. At higher levels unconsciousness, heart failure,
and even death can occur. The following symptoms are related to CARBON MONOX-
IDE 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, cardio-respiratory failure, death.
Many cases of reported carbon monoxide 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,
the elderly, and household pets may be the first affected by CO poisoning.
The important factor with any CO poisoning, however, is time. At high levels, CO can
cause death in just minutes. At lower levels, it could take from hours to days of con-
stant CO exposure to have the same life-threatening effect.
The chart below illustrates the symptoms of CO poisoning by concentration of CO and
its effect over time.
Conditions That Can Cause CO Levels to Change.
The following conditions can result in transient CO situations in the home.
1. Excessive spillage or reverse venting of fuel burning appliances caused by
outdoor ambient conditions, such as:
a. Wind direction and/or velocity, including high gusts of wind. Heavy air in the
vent pipes (cold/humid air with extended periods between cycles).
b. Negative pressure differential resulting from the use of exhaust fans.
c. Simultaneous operation of several fuel burning appliances competing for limited
internal air.
d. Vent pipe connections vibrating loose from clothes dryers, furnaces, or water
heaters.
e. Obstruction in the vent pipe or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.).
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage, or near a home.
