First Alert® ONELINK® Technology is the easy, cost-effective way to provide
your family with whole-home safety. All ONELINK® Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all
sound. This provides your family with an earlier warning of potential danger,
and gives you more time to react.
Do NOT locate this CO Alarm:
• In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or
greasy areas.
• Closer than 15 feet (4.6 meters) from a furnace or other fuel burning heat
source, or fuel burning appliances like a water heater.
• Within 5 feet (1.5 meters) of any cooking appliance.
• 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.
• In turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air
returns, or open windows. Blowing air may prevent CO from reaching the
• In direct sunlight.
The communication distance (range) between any two ONELINK® Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such
as the number of floors, number/size of rooms, furniture and types of building
materials used may reduce the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic appliances (refrigerators) and metal
studs. A feature of ONELINK® Alarms is that they operate as a mesh network.
All Alarms will repeat any alarm signal that is received to all other ONELINK®
Alarms. Interference from structural conditions can be overcome by adding
additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary
depending on its surroundings. It is very important that each
Alarm is tested individually before and after installation to make
sure that all Alarms respond properly.
• The ONELINK® Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly
under these conditions.
• Metal objects and metallic wallpaper may interfere with signals
from wireless Alarms. Alarms should be tested after changes to
your home such as remodeling, moving furniture, and with metal
doors opened and closed.
Your First Alert® ONELINK® CO Alarm will automatically communicate both
potential fires and carbon monoxide presence with all other First Alert®
ONELINK® Smoke/CO Alarms.
FCC NOTICE: This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference

What You See and Hear
• Test the CO Alarm once a week. If the CO Alarm ever fails to test
properly, have it replaced immediately! If the CO Alarm is not
working properly, it cannot alert you to a problem.
Refer to section “What You Will See and Hear With This Alarm”.
• 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.
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds,
you must not ignore it!
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this CO
You can test this CO Alarm by pressing and holding the Test/Silence button
on the Alarm cover (typically 3-5 seconds).
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:
During testing, you will see and hear the following sequence:
3. Immediately move to fresh air—outdoors or by an open door or window.
Do a head count to check that all persons are accounted for. Do not reenter the premises, or move away from the open door or window until the
emergency services responder has arrived, the premises have been aired
out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour
period, repeat steps 1-3 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances, and
inspect for proper operation of this equipment. If problems are identified
during this inspection have the equipment serviced immediately. Note any
combustion equipment 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 operating in an attached garage or
adjacent to the residence. Write down the number of a qualified appliance
technician here:
• The Horn will sound 4 beeps, pause, 4 beeps. The Power LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and
test again. If the unit still does not alarm, replace it immediately.
This unit has been designed to be as maintenance-free as possible, but there
are a few simple things you must do to keep it working properly.
Use only the replacement batteries listed below. The unit may not
operate properly with other batteries. Never use rechargeable batteries
since they may not provide a constant charge.
Alarms have various limitations. See "General Limitations of CO Alarms"
for details.
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
Test it at least once a week.
Clean the CO Alarm at least once a month; gently vacuum the outside
of the CO Alarm using your household vacuum’s soft brush attachment.
A can of clean compressed air (sold at computer or office supply stores)
may also be used. Follow manufacturer instructions for use. Test the CO
Alarm. Never use water, cleaners or solvents since they may damage the
If the CO Alarm becomes contaminated by excessive dirt, dust and/or
grime, and cannot be cleaned to avoid unwanted alarms, replace the unit
Relocate the unit if it sounds frequent unwanted alarms. See “Where CO
Alarms Should Not Be Installed” for details.
Choosing a replacement battery:
Your CO Alarm requires two standard AA batteries. The following batteries are
acceptable as replacements: Energizer E91. These batteries are available at
many local retail stores.
Never remove the batteries to quiet an unwanted alarm. Removing the
batteries disables the alarm and removes your protection.
Actual battery service life depends on the CO Alarm and the environment in
which it is installed. All the batteries specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested
battery life, you MUST replace the battery immediately once the unit starts
“chirping” (the “low battery warning”).
The Silence Feature is intended to temporarily silence the horn while you
identify and correct the problem. Do not use the Silence Feature in emergency
situations. It will not correct a CO problem.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Alarm by pressing the Test/Silence button on
the alarm cover for at least 3-5 seconds.
To replace the batteries (without removing Alarm from the ceiling or wall):
After the Test/Silence button is released, the Red LED blinks during the silence
2. Press tabs A and B as shown in the
diagram and remove each battery.
When the CO Alarm is Silenced the CO Alarm will remain silent for up to
4 minutes. After 4 minutes, if CO levels remain potentially dangerous the horn
will start sounding again.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals on
the ends of the batteries with the
terminals on the unit.
1. Open the battery compartment.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
This silence feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours. You can silence the low battery warning “chirp” by pressing the
Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8 hours, the
low battery “chirp” will resume. Replace the batteries as soon as possible;
this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will
go into Test Mode and the low battery warning will resume (LED flashes and
unit sounds “chirp” once a minute).
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.
Alarm Latch is activated after an Alarm is exposed to alarm levels of carbon
monoxide. After CO levels drop below alarm levels, the “CO” Red LED will
begin to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit initiated
the alarm.
Low Battery Latch is activated when the Alarm is in the "low battery condition".
When this occurs, the Power LED flashes Green On for 2 seconds/Off for 2
seconds for about 15 minutes. This feature is designed to help you identify
which Alarm needs to have the battery replaced. Although, the Alarm will
sound the low battery chirp approximately once every minute, sometimes
during the initial stages of "low battery", the Alarm will chirp in greater intervals
than one minute, sometimes up to several hours, until the battery reaches a
steady low battery level. This innovative feature eliminates the frustration of
waiting for and/or identifying which unit is chirping.
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.
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 prevent proper
air movement and cause backdrafting. Never “cap” or cover a chimney
in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas
or oil companies and HVAC companies offer appliance inspections for
a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check
appliances 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 present. Keep the
blower door on the furnace closed. Use vents or fans when they are
available on all fuel-burning appliances. 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
• 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 significantly decrease CO levels.
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 sounds.
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain damage, death.
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.
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:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be
difficult to locate the source of CO. BRK Brands, Inc. shall not be obligated
to pay for any carbon monoxide investigation or service call.
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO over
time (in minutes).
UL2034 Required Alarm Points*:
• 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.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of
30 ppm for 30 days.
Fuel-burning appliances like: portable heater, gas or wood burning fireplace,
gas kitchen range or cooktop, gas clothes dryer.
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.
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.
Improper use of appliance/ device: operating a barbecue grill or vehicle in
an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
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.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by outdoor
conditions such as:
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 sounds. 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
• 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.
• Obstructions in or unconventional vent pipe designs which can amplify
the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
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 at
the Alarm, 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.
3. Temperature inversions, which can trap exhaust close to the ground.
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.
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.
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
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
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 may not be heard. The alarm horn loudness meets or exceeds
current UL standards of 85 dB at 10 feet (3 meters). 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 prevent alert persons from hearing the alarm horn.
This CO Alarm is not intended for people who are hearing impaired.
CO alarms may not waken all individuals. If children or others do not readily
waken to the sound of the CO alarm, or if there are infants or family members
with mobility limitations, make sure that someone is assigned to assist them in
the event of an emergency.
CO Alarms will not work without power. This alarm requires a two (2) AA
batteries to operate.
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 for Solar or Wind Energy users and battery backup power
systems: AC powered CO Alarms should only be operated with true or pure
sine wave inverters. Operating this Alarm with most battery-powered UPS
(uninterruptible power supply) products or square wave or “quasi sine wave”
inverters will damage the Alarm. If you are not sure about your inverter or
UPS type, please consult with the manufacturer to verify.
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.
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 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.
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
