Model

CO5120PDB

120VAC 60 Hz 0.09A

FEATURES

This CO Alarm is designed to be hard-wired and mounted on any standard size junction box, up to 4” size. 120V AC power to the junction box must not be controlled by a dimmer or switch (other than a circuit breaker.)

This CO Alarm 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).

General features: This Alarm features a permanently installed sensor, a red indicator light (LED), and an 85 dB alarm horn.

9V Battery Back-Up. If AC power is interrupted, the CO Alarm will continue to operate for a short time, provided the 9V battery is fresh and correctly installed.

Silence Feature. The Silence feature temporarily quiets the alarm.

Low Battery Silence Feature. Temporarily silences the Low Battery Warning “chirp” for up to 8 hours if AC power is present.

Digital Display. Shows levels of CO, measured in parts per million present and any stored peak levels.

Malfunction Warning. This unit performs self-diagnostic tests approximately every second. If the alarm malfunctions, it should be replaced immediately.

CHAPTER 1: INTRODUCTION

BASIC SAFETY INFORMATION

Dangers, Warnings, and Cautions alert you to important operating instructions or to potentially hazardous situations. Pay special attention to these items.

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.

This CO Alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.

This CO Alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas.

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 unit does not work without power. If the AC power fails, the battery back-up will power the alarm for at least 20 hours provided the 9V battery is fresh and correctly installed.

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.

Required Alarm Levels: Before 10% COHb exposure at levels of 30% to 70% Relative Humidity (RH):

• 400 ppm CO between 4 and 15 minutes

• 150 ppm CO between 10 and 50 minutes

• 70 ppm CO between 60 and 240 minutes

When exposed to a constant level of 30 ppm of CO, this CO Alarm was tested not to go into alarm for at least 30 days.

Audible Alarm: 85dB minimum at 10 feet.

Power: Powered by 120VAC. The 9V battery back-up

provides 8 hours of standby and sounds alarm for 12 hours with fresh battery. When AC power is on, red light (LED) shines continuously. Under battery power, red light flashes once a minute.

Malfunction: Horn chirps and light blinks 3 times (in rapid succession) every minute and digital display shows “Err”.

Dimensions: 5.4” diameter (approx.)

Supply Voltage: 120VAC 60Hz, 0.09A.

During Alarm: Repeating alarm horn pattern:

4 beeps, pause, 4 beeps, pause.

• Stand-alone unit: red light (LED) flashes once

per second.

• Interconnected series: red light (LED) flashes

once per second on the Initiating alarm. The red light (LED) on all other alarms will shine continuously.

Warranty: 5-year limited warranty.

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.

CO ALARM SPECIFICATIONS

CHAPTER 2: 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, 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), where possible*, away from the furnace or fuel burning heat source.

IN A MULTI-LEVEL HOME:

• 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), where possible*, away from the furnace or fuel burning heat source.

(*)In smaller homes or in manufactured homes and RV’s where this distance cannot be maintained, install the Alarm as far away from the furnace or other fuel burning source. Installing the Alarm closer than 20 feet (6 meters) will not harm the Alarm, but may increase the frequency of nuisance alarms.

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.

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 Alarm Red LED Flashes Once per

Second

On All Other Alarms Red LED Shines Continuously

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.

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.

Interconnect units within a single family residence only. Otherwise all households 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. It is recommended only BRK Electronics® carbon monoxide alarms CO5120B, and CO5120PDB be interconnected.

exposed to this level. This level may be life threatening to a normal healthy adult within three hours.

A number higher Over 450 ppm has been detected. than 450 Evacuate immediately!

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 the “Alarm” level, it 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.

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 pressing the test button.

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.

FINDING THE SOURCE OF CO AFTER AN ALARM

Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. See Chapter 5 “What You Need to Know About CO.” BRK Brands, Inc. shall not be obligated to pay for any carbon

monoxide investigation or service call.

CHAPTER 4: TESTING AND MAINTENANCE

WEEKLY TESTING

Push and hold the Test/Silence button until 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”.

•

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.

• 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.

REGULAR MAINTENANCE

To keep the CO Alarm in good working order:

• 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.

Household cleaners, aerosol chemicals and other contaminants can affect sensor. When using any of these materials near Alarm, make sure room is well ventilated.

DO NOT spray cleaning chemicals or insect sprays directly on or near the Alarm. DO NOT paint over the Alarm, this may permanently damage the Alarm. DO NOT expose the Alarm to strong fumes such as painting or fumigat

ing.

THE LOW (OR MISSING) BATTERY WARNING:

NOTE: You should replace the battery immediately to

continue your protection. LOW BATTERY SILENCE FEATURE. If AC power is on,

press the Test/Silence button to silence the low battery “chirp” for up to 8 hours. The alarm will continue to operate as long as AC power is supplied. However, replace the battery as soon as possible, to maintain protection in event of a power outage.

Choosing a replacement battery: This unit requires one standard 9V alkaline battery. The following alkaline batteries are acceptable as replacements. This list supplements the list on the carbon monoxide alarm battery door: Eveready #522 (Energizer); Duracell #MN1604, MX1604 (Ultra). You may also use a Lithium battery like an Ultralife U9VL-J for longer service between battery changes. These batteries are available at many local retail stores. 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.

Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.

The horn will “chirp” once a minute and the word “bat” will flash on and off on the display.

CHAPTER 5: 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 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.

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.

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.

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.

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-offagain 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.

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 portable/outdoor 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.

In addition, familiarize yourself with the enclosed checklist, read this manual in its entirety, and make sure you understand what to do if your CO Alarm sounds.

CHAPTER 6: UNDERWRITERS LABORATORIES INC. UL2034

WHAT LEVELS OF CO CAUSE AN ALARM?

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).

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.

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.

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!

Once a minute, the alarm sounds 3 quick “chirps”, and the red light flashes quickly three times and display reads “Err”.

Based on its Self Test diagnostics, the unit has detected a malfunction. The unit needs to be replaced.

Units under warranty should be returned to manufacturer for replacement. See “Limited Warranty” for details.

Once a minute, the red light flashes and the horn “chirps” and flashing “bat” displays continuously.

Low battery warning. Replace the 9V battery in the battery

back-up. Disconnect AC power before changing the battery.

If your CO Alarm does this... This means... You should...

Red light is OFF. Unit will not alarm when you press the Test/Silence button.

Unit may not be receiving any power. Check the AC power supply. Make sure

the power connector is securely attached to the Alarm. Make sure a fresh 9V battery is installed to power the battery back-up.

Red light flashes once a minute (horn is silent). Display shows “bat”.

Alarm is not receiving AC power. Unit is operating on DC battery back-

up. Check the AC power supply.

CHAPTER 7: TROUBLESHOOTING GUIDE

CO Alarm goes back into alarm 4 minutes after you press the Test/Silence button.

CO levels are still potentially dangerous. Refer to Chapter 3 “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.

If you have any questions that cannot be answered by reading this manual, call Consumer Affairs:1-800-323-9005.

CO Alarm sounds frequently even though no high levels of CO are revealed in an investigation.

The CO Alarm may be improperly located. Refer to “Where to Install Your CO Alarm.”

Relocate your Alarm. If frequent alarms continue, have home rechecked for potential CO problems. You may be experiencing an intermittent CO problem.

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.

The following guide can help you identify a potential problem with the installation or operation of your CO Alarm. It is not meant to be an all-inclusive list of all CO Alarm conditions. If you are experiencing a condition not covered in the next several pages, please contact Consumer Affairs.

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, and a fresh, correctly installed 9V battery to power the battery back-up.

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 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.
