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).  
(Behind the Cover) Alarm Horn: 85db

Standards: Underwriters Laboratories Inc.  
Single and Multiple Station carbon monoxide  
alarms UL2034.  
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.

CHAPTER 2: Installation  
In a Single-level Home:  
WHERE TO INSTALL  
CO ALARMS  
Install at least one CO Alarm near or  
within each separate sleeping area.  
The Consumer Product Safety Commission  
(CPSC) recommends the use of at least one CO  
Alarm per household, located near the sleeping  
area. For added protection, install additional  
CO Alarms in each separate bedroom, and on  
every level of your home.  
For added protection, install an additional  
CO Alarm at least 20 feet (6 meters) away  
from the furnace or fuel burning heat  
source.  
In a Multi-level Home:  
If your bedroom hallway is longer than 40 feet,  
install a CO Alarm at BOTH ends of the hallway.  
Install at least one CO Alarm near or  
within each separate sleeping area.  
For added protection, install at least one  
CO Alarm on each level of the home. If  
you have a basement, install that CO  
Alarm at the top of the basement stairs.  
For added protection, install an additional  
CO Alarm at least 20 feet (6 meters) away  
from the furnace or fuel burning heat  
source.

WHERE NOT TO INSTALL  
CO ALARMS  
WARN IN G!  
This CO Alarm is designed for use inside a  
single-family home or apartment. It is not  
meant to be used in common lobbies,  
hallways, or basements of multi-family  
buildings unless working CO Alarms are also  
installed in each family living unit. CO  
Alarms in common areas may not be heard  
from inside individual family living units.  
DO NOT locate this CO Alarm:  
In garages, kitchens, furnace rooms,  
or in any extremely dusty, dirty or  
greasy areas.  
Closer than 20 feet from a furnace or  
other fuel burning heat source, or fuel  
burning appliances like a water heater.  
WARN IN G!  
Within 5 feet of any cooking appliance.  
This CO Alarm alone is not a suitable  
substitute for complete detection systems in  
places which house many people, like hotels  
or dormitories, unless a CO Alarm is also  
placed in each unit.  
In extremely humid areas. This alarm  
should be at least 10 feet from a bath  
or shower, sauna, humidifier, vaporizer,  
dishwasher, laundry room, utility room  
or other source of high humidity.  
WARN IN G!  
In areas where temperature is colder than  
40˚F (4˚C) or hotter than 100˚F (38˚C).  
These areas include unconditioned crawl  
spaces, unfinished attics, uninsulated or  
poorly insulated ceilings, porches, and  
garages.

While the detector is silenced:  
Using the Silence Feature  
If the CO Alarm... is silent for only  
4 minutes, then starts sounding loudly—  
4 beeps, then a pause, 4 beeps, then a pause.  
Red light continues flashing...  
WARN IN G!  
NEVER unplug your CO alarm to silence the  
horn. Use the silence feature. Unplugging  
the CO alarm removes your protection!  
See previous page for details on responding  
to an alarm.  
This means... CO levels are still potentially  
dangerous.  
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...remains silent.  
Only the green light is on....  
This means...unit has returned to normal  
operation.  
When CO reaches the Full Alarm level, the  
Alarm will sound— repeating horn pattern:  
4 beeps, a pause, 4 beeps, etc. Press and hold  
the Test/Silence button until the horn is silent.  
The initial Silence cycle will last approximately  
4 minutes.  
N O TE:  
After initial 4-minute Silence cycle, the  
CO Alarm re-evaluates present CO levels and  
responds accordingly. If CO levels remain  
potentially dangerous—or start rising higher—  
the horn will start sounding again.

CHAPTER 4: Testing and Maintenance  
WEEKLY TESTING  
REGULAR MAINTENANCE  
To keep the CO Alarm in good  
working order:  
Push and hold the Test/Silence button on the  
cover until a loud alarm sounds— 4 beeps, a  
pause, then 4 beeps. The alarm sequence  
should last for 5-6 seconds. If the Alarm ever  
fails to test properly, replace it immediately.  
Test it every week using the  
Test/Silence button.  
Vacuum the CO Alarm cover at least  
twice a year, using the soft brush  
attachment. Test the Alarm again after  
vacuuming.  
If the CO Alarm is not working properly, refer  
to the “Limited Warranty” at the end of this  
manual.  
CAUTIO N !  
WARN IN G!  
DO NOT spray cleaning chemicals or insect  
sprays directly on or near the CO Alarm. DO  
NOT paint over the CO Alarm. Doing so may  
permanently damage the CO Alarm.  
The Test/Silence button is the only proper  
way to test the CO Alarm. NEVER use  
vehicle exhaust! Exhaust may cause  
permanent damage and voids your warranty.  
IMPO RTAN T!  
WARN IN G!  
DO NOT stand close to the alarm when the  
horn is sounding. Exposure at close range  
may be harmful to your hearing. When  
testing, step away when horn starts  
sounding.  
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.  
IMPO RTAN T!  
If your home is being fumigated, unplug the unit  
temporarily and put it where it will not be  
exposed to chemicals or fumes. When  
fumigation is complete and all traces of fumes  
clear, plug the unit back in and retest it.

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  
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.  
11  
 
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 insufcient 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  
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.

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.
