BASIC SAFETY INFORMATION  
WARN IN G!  
This CO Alarm can not operate without  
continuous electricity. It does not operate  
during a power failure.  
IMPO RTAN T!  
Dangers, Warnings, and Cautions alert you to  
important operating instructions or to  
potentially hazardous situations. Pay special  
attention to these items.  
WARN IN G!  
NEVER ignore your Carbon Monoxide Alarm  
if it alarms. Refer to What To Do If Your CO  
Alarm Alarms” for more information. Failure  
to do so can result in injury or death.  
IMPO RTAN T!  
THIS IS NOT A SMOKE ALARM! This CO Alarm  
is designed to detect carbon monoxide from  
ANY source of combustion. It is NOT designed  
to detect smoke, fire, or any other gas.  
WARN IN G!  
Test the CO Alarm once a week. If the CO  
Alarm ever fails to test correctly, have it  
replaced immediately! If the CO Alarm is not  
working properly, it cannot alert you to a  
problem.  
IMPO RTAN T!  
This CO Alarm is approved for use in single-  
family residences. It is NOT designed for marine  
use.  
WARN IN G!  
This product is intended for use in ordinary  
indoor locations of family living units. It is  
not designed to measure CO levels in  
compliance with Occupational Safety and  
Health Administration (OSHA) commercial  
or industrial standards. Individuals with  
medical conditions may consider using  
warning devices which provide audible and  
visual signals for carbon monoxide  
CAUTIO N !  
This CO Alarm will only indicate the  
presence of carbon monoxide gas at the  
sensor. Carbon monoxide gas may be  
present in other areas.  
WARN IN G!  
The Silence Feature is for your convenience  
only and will not correct a CO problem.

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 re).  
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 efcient. Air-tighthomes with  
added insulation, sealed windows, and other  
weatherproong can trapCO inside.  
Finding the Source of CO  
After an Alarm  
Carbon monoxide is an odorless, invisible gas,  
which often makes it difcult to locate the  
source of CO after an alarm. These are a few of  
the factors that can make it difcult 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 (u-likesymptoms).  
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 replace, 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 ue, or cracked heat  
exchanger, blocked or clogged chimney  
opening.  
2. Extended operation of unvented fuel  
burning devices (range, oven, replace).  
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: transientor 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 backow 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 signi-  
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 ues yearly. Keep  
them free of debris, leaves, and nests for  
proper air ow. Also, have a professional  
check for rust and corrosion, cracks, or  
separations. These conditions can pre-  
vent proper air movement and cause  
backdrafting. Never capor cover a

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 ame on the burner and  
pilot lights. The ame should be blue. A  
yellow ame 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 denes  
3 specic 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 rst 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 its 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 trafc,  
stereo, radio, television, air conditioner, or other  
CO Alarms are not a substitute for a smoke  
alarm. Although re is a source of carbon  
monoxide, this CO Alarm does not sense smoke  
or re. This CO Alarm senses CO that may be  
escaping unnoticed from malfunctioning furnaces,  
appliances, or other sources. Early warning of re  
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.
