This CO Alarm is intended for use in a standard,
unswitched 120V AC 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 and takes a new
reading about every second. 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). When the unit is in alarm
mode, the Digital Display will show the levels of
CO, measured in parts per million, present. This
Carbon Monoxide Alarm features a permanently
installed sensor, three colored indicator lights, and
an 85 dB alarm horn. It also has a silence feature
to temporarily quiet the alarm horn.

WHAT THE DIGITAL DISPLAY CAN SHOW YOU
The Digital Display is designed to indicate estimated carbon monoxide levels in a residential
environment. It is not intended for use as an industrial or commercial grade meter. The Digital Display
shows the amount of carbon monoxide (measured in parts per million) the unit is sensing. An average,
healthy adult should not feel symptoms when the unit first alarms. However, infants, the unborn, and
people with cardiac or respiratory diseases may be more sensitive to CO exposure. See “What To Do
If Your CO Alarm Alarms” for complete details on how to respond to an alarm.

CHAPTER 5: What You Need To Know About CO
What is CO?
CAUTIO N !
Some individuals are more sensitive to CO
than others, including people with cardiac or
respiratory problems, infants, unborn
babies, pregnant mothers, or elderly people
can be more quickly and severely affected
by CO. Members of sensitive populations
should consult their doctors for advice on
taking additional precautions.
CO is an invisible, odorless, tasteless gas
produced when fossil fuels do not burn
completely, or are exposed to heat (usually fire).
Electrical appliances typically do not
produce CO.
These fuels include: Wood, coal, charcoal, oil,
natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If
they are not properly maintained, are improperly
ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are
more energy efficient. “Air-tight” homes with
added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
Finding the Source of CO
After an Alarm
Carbon monoxide is an odorless, invisible gas,
which often makes it difficult to locate the
source of CO after an alarm. These are a few of
the factors that can make it difficult to locate
sources of CO:
Symptoms of CO Poisoning
•
House well ventilated before the
investigator arrives.
Problem caused by “backdrafting.”
Transient CO problem caused by
special circumstances.
These symptoms are related to CO
POISONING and should be discussed with
ALL household members.
•
•
Mild Exposure Slight headache, nausea,
vomiting, fatigue (“flu-like” symptoms).
Medium Exposure Throbbing headache,
BRK Brands, Inc. shall not be obligated to
pay for any carbon monoxide investigation
or service call.
drowsiness, confusion, fast heart rate.
Extreme Exposure Convulsions,
unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain
damage, death.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
The following conditions can result in
transient CO situations:
Potential Sources Of CO
In The Home
1. Excessive spillage or reverse venting of fuel
appliances caused by outdoor conditions
such as:
•
Wind direction and/or velocity, including
high, gusty winds. Heavy air in the vent
pipes (cold/humid air with extended peri-
ods between cycles).
•
•
•
Negative pressure differential resulting
from the use of exhaust fans.
Several appliances running at the same
time competing for limited fresh air.
Vent pipe connections vibrating loose
from clothes dryers, furnaces, or water
heaters.
Fuel-burning appliances like: portable heater,
gas or wood burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
•
Obstructions in or unconventional vent
pipe designs which can amplify the
above situations.
Damaged or insufficient venting: corroded or
disconnected water heater vent pipe, leaking
chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney
opening.
2. Extended operation of unvented fuel
burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap
exhaust close to the ground.
Improper use of appliance/device: operating
a barbecue grill or vehicle in an enclosed area
(like a garage or screened porch).
4. Car idling in an open or closed attached
garage, or near a home.
These conditions are dangerous because they
can trap exhaust in your home. Since these
conditions can come and go, they are also hard
to recreate during a CO investigation.
Transient CO problems: “transient” or on-
again-off-again CO problems can be caused by
outdoor conditions and other special
circumstances.

present. Keep the blower door on the fur-
nace closed. Use vents or fans when they
are available on all fuel-burning appli-
ances. Make sure appliances are vented
to the outside. Do not grill or barbecue
indoors, or in garages or on screen
porches.
Check for exhaust backflow from CO
sources. Check the draft hood on an
operating furnace for a backdraft. Look
for cracks on furnace heat exchangers.
Check the house or garage on the other
side of shared wall.
Keep windows and doors open slightly. If
you suspect that CO is escaping into
your home, open a window or a door.
Opening windows and doors can signifi-
cantly decrease CO levels.
How Can I Protect My Family?
A CO Alarm is an excellent means of protection.
It monitors the air and sounds a loud alarm
before Carbon Monoxide levels become
threatening for average, healthy adults.
A CO Alarm is not a substitute for proper
maintenance of home appliances.
•
To help prevent CO problems and reduce the
risk of CO poisoning:
•
•
•
Clean chimneys and flues yearly. Keep
them free of debris, leaves, and nests for
proper air flow. Also, have a professional
check for rust and corrosion, cracks, or
separations. These conditions can pre-
vent proper air movement and cause
backdrafting. Never “cap” or cover a
chimney in any way that would block air
flow.
In addition, familiarize yourself with all
enclosed materials. Read this manual in its
entirety, and make sure you understand
what to do if your CO Alarm alarms.
•
•
Test and maintain all fuel-burning equip-
ment annually. Many local gas or oil com-
panies and HVAC companies offer
appliance inspections for a nominal fee.
Make regular visual inspections of all
fuel-burning appliances. Check appli-
ances for excessive rust and scaling.
Also check the flame on the burner and
pilot lights. The flame should be blue. A
yellow flame means fuel is not being
burned completely and CO may be

CHAPTER 6: Underwriters Laboratories Inc. UL2034
What Levels of CO Cause an Alarm?
IMPO RTAN T!
Underwriters Laboratories Inc. UL2034 defines
3 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).
This CO Alarm measures exposure to CO over
time. It alarms if CO levels are extremely high in
a short period of time, or if CO levels reach a
certain minimum over a long period of time. The
CO Alarm generally sounds an alarm before the
onset of symptoms in average, healthy adults.
UL2034 Required Alarm Points:
Why is this important? Because you need to be
warned of a potential CO problem while you
can still react in time. In many reported cases of
CO exposure, victims may be aware that they
are not feeling well, but become disoriented
and can no longer react well enough to exit the
building or get help. Also, young children and
pets may be the first affected. The average
healthy adult might not feel any symptoms
when the CO Alarm alarms. However, people
with cardiac or respiratory problems, infants,
unborn babies, pregnant mothers, or elderly
people can be more quickly and severely
affected by CO. If you experience even mild
symptoms of CO poisoning, consult your
doctor immediately!
•
•
•
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.
IMPO RTAN T!
CO Alarms are designed to alarm before there
is an immediate life threat. Since you cannot

CHAPTER 8: General Limitations Of CO Alarms
This CO Alarm is intended for residential use. It is not intended for use in industrial applications
where Occupational Safety and Health Administration (OSHA) requirements for carbon monoxide
detectors must be met.
CO Alarms will not work without power.This CO
Alarm requires a continuous supply of AC power.
Plug into an unswitched 120V AC outlet only.
appliances may also prevent alert persons from
hearing the alarm horn. This CO Alarm is not
intended for people who are hearing impaired.
This CO Alarm will not sense carbon monoxide
that does not reach the sensor. This CO Alarm
will only sense CO at the sensor. CO may be
present in other areas. Doors or other obstructions
may affect the rate at which CO reaches the CO
Alarm. For this reason, if bedroom doors are
usually closed at night, we recommend you install
a CO Alarm in each bedroom and in the hallway
between them.
CO Alarms may not sense CO on another level
of the home. For example, a CO Alarm on the
second level, near the bedrooms, may not sense
CO in the basement. For this reason, one CO
Alarm may not give adequate warning. Complete
coverage is recommended. Place CO Alarms on
each level of the home.
CO Alarms may not be heard. The alarm horn
loudness meets or exceeds current UL standards
of 85 dB at 10 feet. However, if the CO Alarm is
installed outside the bedroom, it may not wake up
a sound sleeper or one who has recently used
drugs or has been drinking alcoholic beverages.
This is especially true if the door is closed or only
partly open. Even persons who are awake may not
hear the alarm horn if the sound is blocked by
distance or closed doors. Noise from traffic,
stereo, radio, television, air conditioner, or other
CO Alarms are not a substitute for a smoke
alarm. Although fire is a source of carbon
monoxide, this CO Alarm does not sense smoke
or fire. This CO Alarm senses CO that may be
escaping unnoticed from malfunctioning furnaces,
appliances, or other sources. Early warning of fire
requires the installation of smoke alarms.
CO Alarms are not a substitute for life
insurance. Though these CO Alarms warn against
increasing CO levels, BRK Brands, Inc. does not
warrant or imply in any way that they will protect
lives from CO poisoning. Homeowners and renters
must still insure their lives.
CO Alarms have a limited life.Although the CO
Alarm and all of its parts have passed many
stringent tests and are designed to be as reliable
as possible, any of these parts could fail at any
time. Therefore, you must test your CO Alarm
weekly.
CO Alarms are not foolproof. Like all other
electronic devices, CO Alarms have limitations.
They can only detect CO that reaches their
sensors. They may not give early warning to rising
CO levels if the CO is coming from a remote part
of the home, away from the CO Alarm.
