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 |
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
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. |

What you see and hear if CO is detected:
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. |
STAND ALONE ALARM ONLY:
•If you are only installing one unit, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
•If you are interconnecting multiple Alarms, repeat Step 1-5 for each Alarm in the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.
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. |

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!
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. |
• 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. |

• 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.

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 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.
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).

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.
HOW TO INSTALL YOUR CO ALARM
Tools you will need: Standard Flathead screwdriver.

Interconnect units within a single family residence only. Otherwise all house- holds will experience unwanted alarms when you test any unit in the series. Interconnected units will only work if they are wired to compatible units and all requirements are met. This unit is designed to be compatible with: BRK Electronics® Smoke Alarm Models SC6120B, 4120, 4120B, 4120SB, 4919, 2002RAC, 100S, 5919, 5919TH; BRK Electronics® Heat Alarm Models HD6135F, HD6135FB; BRK Electronics® CO Alarm Models SC6120B, CO5120BN, CO5120PDBN; and First Alert® Smoke Alarm Models SA4120B, SA4121B, SA4919B, SA100B.
Interconnected units must meet ALL of the following requirements:
•A maximum of 18 compatible BRK Electronics® Smoke, Heat or CO Alarms may be interconnected. No more than 12 of the 18 can be Smoke Alarms per NFPA 72.
•The same fuse or circuit breaker must power all interconnected units.
•The total length of wire interconnecting the units should be less than 1000 feet. The interconnect wire should be Type 18 gauge AWM or larger, rated at least 300V. If an interconnect wire is not already part of your household wiring, you will need to install one. This type of wire is commonly available at Hardware and Electrical Supply stores.
•All wiring must conform to all local electrical codes and Article 760 of the National Electrical Code. Refer to NFPA, Chapter 2 and/or your local building code for further connection requirements.
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.
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
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.
• This unit does not work without power. If the AC power fails, the |
battery back-up will power the alarm for at least 7 days provided |
the 9V battery is fresh and correctly installed. |
• The Silence Feature is for your convenience only and will not correct |
a CO problem. Always check your home for a potential problem after |
any alarm. Failure to do so can result in injury or death. |
• This CO Alarm should receive continuous 120VAC, 60 Hz, pure sine |
wave electrical power. (The battery is meant for emergency back- |
up only). Do not use in an extension cord or outlet controlled by a |
dimmer or switch. In order for the emergency battery back-up to |
work, a working (fresh) battery must be properly installed. |
• NEVER ignore any alarm. See “If Your CO Alarm Sounds” for more |
information on how to respond to an alarm. Failure to respond can |
result in injury or death. |

WEEKLY TESTING
Push and hold the Test/Silence button until you hear an acknowledge chirp and a loud alarm sounds — 4 beeps, pause, 4 beeps. This sequence should last for 10 seconds. If the Alarm ever fails to test properly, replace it immediately. If the Alarm is not working properly, refer to “Limited Warranty”.
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 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.

To keep the CO Alarm working properly:
•Test it every week as described in “Weekly Testing.”
•Vacuum the CO Alarm cover at least once a month, using the soft brush attachment. Never use water, cleaners, or solvents, since they may damage the unit. Test the Alarm again after vacuuming.
•Replace the battery immediately when you see/hear the “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.
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.

• 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. |
