“Low Battery Warning”.
The Low (or Missing) Battery Warning (CO5120PDBN):
The horn will “chirp” once a minute and the word “bat” will flash on and off on
the display.
REPLACING THE BATTERY
Choosing a replacement battery: This unit requires one standard 9V alkaline
battery. The following alkaline batteries are acceptable as replacements:
Duracell #MN1604 or MX1604; Eveready “Energizer” 522. You can also use an
Ultralife 9 volt lithium battery #U9VL for longer service life between battery
changes. These replacement batteries are commonly available at local retail
stores.
Use only the alkaline or lithium replacement batteries listed. The unit may not
operate properly with other batteries. Never use rechargeable batteries since
they may not provide a constant charge.
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 cause
permanent damage.
•
Household cleaners, aerosol chemicals and other contaminants can affect the
sensor. When using any of these materials near the CO Alarm, make sure the
room is well ventilated.
•
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.
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.
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.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).

IF YOUR CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon monoxide (CO)
which can kill you. When your CO Alarm sounds, you must not ignore it!
IF THE ALARM SOUNDS:
1.
Operate the Test/Silence button to silence the alarm.
2.
Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:
________________________________________________________________
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 re-
enter 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:
_________________________________________________________________
Alarms have various limitations. See "General Limitations of CO Alarms"
for details.
USING THE SILENCE FEATURE
NEVER disconnect the power to your CO Alarm to silence the horn—
use the silence feature. Disconnecting the CO Alarm removes your
protection! See previous page for details on responding to an alarm.
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. When CO reaches
alarm level, the unit 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
Silence cycle will last approximately 4 minutes.
To silence an interconnected series of Alarms, you must press the Test/
Silence button on the initiating alarm (the unit with the flashing red light).
If you press the Test/Silence on any other Alarm, it will only silence that unit,
not the whole interconnected series.
NOTE: After the 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.
While the CO Alarm is silenced:
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 (LED) continues flashing...
This means...CO levels are still potentially dangerous.
If the CO Alarm...remains silent....
This means...unit has returned to normal operation.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours if AC power is present. Press the Test/Silence button on the
alarm cover. Once the low battery warning “chirp” silence feature is activated,
the unit continues to flash the red light once a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the battery as soon as
possible, to maintain protection in the event of a power outage.
THE “LATCHING ALARM” INDICATOR:
The Latching Alarm Indicator is activated after a CO Alarm is exposed to
alarm levels of carbon monoxide. After CO levels drop below alarm levels, the
red LED will begin to flash once every 5 seconds. It will continue to flash or
“latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of carbon
monoxide. This can help investigators pinpoint the source of CO.
Interconnected Alarms. Latching Alarm Indicator shows which Alarm(s) in the
series were exposed to alarm levels of carbon monoxide.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you to
a CO Alarm that occurred while you were away from home, even though CO
present in the air has dropped below alarm levels.

INSTALLATION
WHERE TO INSTALL CO ALARMS
The National Fire Protection Association (NFPA) recommends that a CO Alarm
should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO
Alarms in each separate bedroom, and on every level of your home.
If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm
at BOTH ends of the hallway.
In a Single-level Home:
• Install at least one CO Alarm near or within each separate sleeping area.
• 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—(same as above plus):
• 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 CO ALARMS SHOULD NOT BE INSTALLED
DO NOT locate this CO Alarm:
•
In garages, kitchens, furnace rooms, or in any extremely dusty, dirty
or greasy areas.
•
Where combustion particles are produced. Combustion particles form
when something burns. Areas to avoid include poorly ventilated kitchens,
garages, and furnace rooms. Keep units at least 20 feet (6 meters) from
the sources of combustion particles (stove, furnace, water heater, space
heater) if possible. In areas where a 20-foot (6 meter) distance is not
possible — in modular, mobile, or smaller homes, for example — it is
recommended the CO Alarm be placed as far from these fuel-burning
sources as possible. The placement recommendations are intended to
keep these Alarms at a reasonable distance from a fuel-burning source,
and thus reduce “unwanted” alarms. Unwanted alarms can occur if a CO
Alarm is placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
•
Within 5 feet (1.5 meter) of any cooking appliance.
•
In extremely humid areas. This Alarm should be at least 10 feet (3 meter)
from a bath or shower, sauna, humidifier, vaporizer, dishwasher, laundry
room, utility room or other source of high humidity.
•
In areas where temperature is colder than 40˚ F (4˚ C) or hotter than 100˚ F
(38˚ C). These areas include non-airconditioned 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 sensors.
•
In direct sunlight.
• 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.
• 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.
• DO NOT use this CO Alarm in warehouses, industrial or commercial
buildings, special-purpose non-residential buildings, RVs, boats,
or airplanes. This CO Alarm is specifically designed for residential
use, and may not provide adequate protection in non-residential
applications.

REQUIRED TO MEET NFPA RECOMMENDATIONS
BEFORE YOU BEGIN INSTALLATION
This unit is designed to be mounted on any standard wiring junction box up
to a 4-inch (10 cm) size, on either the ceiling or wall. Read “Where to Install CO
Alarms” and “Where Not To Install CO Alarms” before you begin installation.
If a junction box is not already in place, install one using standard #12 or #14
gauge copper wire.
• This Alarm must have AC or battery power to operate. If the AC
power fails, the battery back-up will power the Alarm for a short
time if the 9V battery is fresh and correctly installed. If AC power
fails, and the battery is dead or missing, the Alarm cannot operate.
• Make sure the alarm is not receiving excessive noisy power.
Examples of noisy power could be major appliances on the same
circuit, power from a generator or solar power, light dimmer on the
same circuit or mounted near fluorescent lighting. Excessive noisy
power may cause damage to your Alarm.
Find the pair of self-adhesive labels included with this CO Alarm.
• On each label write in the phone number of your emergency responder
(like 911) and a qualified appliance technician.
• Place one label near the CO Alarm, and the other label in the “fresh air”
location you plan to go if the alarm sounds.
NOTE: A qualified appliance technician is defined as “a person, firm, corporation,
or company that either in person or through a representative, is engaged in and
responsible for the installation, testing, servicing, or replacement of heating,
ventilation, air conditioning (HVAC) equipment, combustion appliances and
equipment, and/or gas fireplaces or other decorative combustion equipment.”

STAND ALONE ALARM ONLY:
• Connect the white wire on the power connector to the neutral wire
in the junction box.
• Connect the black wire on the power connector to the hot wire in
the junction box.
•
Tuck the orange wire inside the junction box. It is used for
interconnect only.
INTERCONNECTED ALARMS ONLY:
Strip off about 1/2” of the plastic coating on the orange interconnect
wire on the power connector.
•
Connect the white wire on the power connector to the neutral wire
(usually white) in the junction box.
•
Connect the black wire on the power connector to the hot wire (usually
black) in the junction box.
•
Connect the orange wire on the power connector to the interconnect
wire in the junction box. Repeat for each unit you are interconnecting.
Never connect the hot or neutral wires in the junction box to the
orange interconnect wire.
SPECIAL REQUIREMENTS FOR INTERCONNECTED CO ALARMS
• Failure to meet any of the above requirements could damage the
units and cause them to malfunction, removing your protection.
• AC and AC/DC CO Alarms can be interconnected. Under AC power,
all units will alarm when one senses CO. When power is interrupted,
only the AC/DC units in the series will continue to send and receive
signals. AC powered CO Alarms will not operate.
Interconnected units can provide earlier warning of a CO problem than stand-
alone units, especially if the problem starts in a remote area of the dwelling. If
any unit in the series senses CO, all units will alarm. To determine which CO
Alarm initiated an alarm, refer to the table.
On Initiating CO Alarm

HOW TO INSTALL YOUR CO ALARM
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:
• 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.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like:
portable heater, gas or wood
burning fireplace, gas kitchen range
or cooktop, gas clothes dryer.
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.
The following conditions can result in transient CO situations:
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.
• Obstructions in or unconventional vent pipe designs which can amplify
the above situations.
2.
Extended operation of unvented fuel burning devices (range, oven, fireplace).
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.
CO Alarm goes back into alarm 4 minutes after
you press the Test/Silence button.
CO levels are still potentially dangerous.
Refer to “If Your CO Alarm Sounds” for details on
how to respond to an alarm. If anyone is feeling ill,
EVACUATE your home immediately and call 911.
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 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 CO Alarm requires a continuous
supply of AC power, and a fresh, correctly installed 9V battery to power the
battery back-up. The battery back-up is for emergency use only!
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 CO 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.
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 (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 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.
UNDERWRITERS LABORATORIES INC. UL2034
WHAT LEVELS OF CO CAUSE AN ALARM?
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.
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.
GENERAL LIMITATIONS OF CO ALARMS
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where
the CO Alarm is installed BEFORE removing it from the mounting
bracket or checking any electrical connections! Failure to turn off the
power first may result in serious electrical shock, injury or death.

INSTALLATION, continued
SYMPTOMS OF CO POISONING
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, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain damage, death.
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.
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 immediately!
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
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 main-
tained, 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.
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 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 use grills 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 significantly decrease CO levels.
