HOW YOUR CO ALARM WORKS
General Information
A CO Alarm measures the CO levels in the air. It
will alarm if CO levels rise quickly (if the heat
exchanger on your furnace breaks, for
example), or if CO is consistently present (a
slow CO leak on a fuel-burning appliance).
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.

CO ALARM SPECIFICATIONS
Standards: Underwriters Laboratories Inc.
Single and Multiple Station carbon monoxide
alarms UL2034.
Gas Detection at Typical Temperature and
Humidity Ranges: The CO Alarm is not
formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to
Methane (500 ppm), Butane (300 ppm),
Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon
Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
According to Underwriters Laboratories Inc.
UL2034, Section 1-1.2: “Carbon monoxide
alarms covered by these requirements are
intended to respond to the presence of carbon
monoxide from sources such as, but not limited
to, exhaust from internal-combustion engines,
abnormal operation of fuel-fired appliances,
and fireplaces. CO alarms are intended to alarm
at carbon monoxide levels below those that
could cause a loss of ability to react to the
dangers of Carbon Monoxide exposure.” This
CO Alarm monitors the air, and is designed to
alarm before CO levels become life threatening.
This allows you precious time to leave the
house and correct the problem. This is only
possible if alarms are located, installed, and
maintained as described in this manual.
Required Alarm Levels: Before 10% COHb
exposure at levels of 30% to 70% Relative
Humidity (RH):
•
•
•
400 ppm CO between 4 and 15 minutes
150 ppm CO between 10 and 50 minutes
70 ppm CO between 60 and 240 minutes
The unit is designed not to alarm when
exposed to a constant level of 30 ppm
for 30 days.
Audible Alarm: 85dB minimum at 10 feet
Power: Powered by 9V battery. Green light
flashes about twice a minute when device is
receiving battery power.
During Alarm: CO Alarm horn sounds while the
red light flashes rapidly.
This CO alarm is designed to sound for up to
12 hours in alarm conditions, provided the
battery is fresh and installed correctly.

Silence button...
WARNING!
NEVER remove the batteries from your
CO Alarm to silence the horn. Use the
silence feature. Removing the batteries
removes your protection! See previous page
for details on responding to an alarm.
This means...
CO levels are dropping.
The silence feature is intended to temporarily
silence your CO Alarm’s alarm horn while you
correct the problem—it will not correct a CO
problem. While the alarm is silenced, it will
continue to monitor the air for CO.
If the CO Alarm...

sprays directly on or near the CO Alarm. DO
NOT paint over the CO Alarm. Doing so may
permanently damage the CO Alarm.
•
Replace the battery when the CO Alarm
“chirps” and the yellow light blinks twice
a minute (the low battery warning).
IMPORTANT!
NOTE:
Household cleaners, aerosol chemicals, and
other contaminants can affect the sensor. When
using any of these materials near the alarm,
make sure the room is well ventilated.
The low battery warning should last for 30
days, but you should replace the battery
immediately to continue your protection.
Choosing a replacement battery:
This unit requires one standard 9V alkaline
battery. The following alkaline batteries are
acceptable as replacements: Duracell

CHAPTER 5: What You Need To Know About CO
What is CO?
CAUTION!
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
These symptoms are related to CO
POISONING and should be discussed with
ALL household members.
•
House well ventilated before the
investigator arrives.
Problem caused by “backdrafting.”
Transient CO problem caused by
special circumstances.
•
•
Mild Exposure Slight headache, nausea,
vomiting, fatigue (“flu-like” symptoms).
Medium Exposure Throbbing headache,
drowsiness, confusion, fast heart rate.
Extreme Exposure Convulsions,
unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain
damage, death.
BRK Brands, Inc. shall not be obligated to
pay for any carbon monoxide investigation
or service call.
13

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
periods 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?
IMPORTANT!
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).
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.
IMPORTANT!
CO Alarms are designed to alarm before there
is an immediate life threat. Since you cannot
see or smell CO, never assume it’s not present.
•
An exposure to 100 ppm of CO for 20
minutes may not affect average, healthy
adults, but after 4 hours the same level
may cause headaches.
•
An exposure to 400 ppm of CO may
cause headaches in average, healthy
adults after 35 minutes, but can cause
death after 2 hours.

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.
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, we recommend if bedroom
doors are usually closed at night, 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.
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 appliances may also
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.
