FIRE SAFETY TIPS

ollow safety rules and prevent hazardous situations: 1) Use smoking

aterials properly. Never smoke in bed. 2) Keep matches or lighters

way from children; 3) Store flammable materials in proper containers;

) Keep electrical appliances in good condition and don’t overload electri-

al circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys

rease- and debris-free; 6) Never leave anything cooking on the stove

nattended; 7) Keep portable heaters and open flames, like candles,

way from flammable materials; 8) Don’t let rubbish accumulate.

eep alarms clean, and test them weekly. Replace alarms immediately

f they are not working properly. Smoke Alarms that do not work cannot a

lert you to a fire. Keep at least one working fire extinguisher on every

loor, and an additional one in the kitchen. Have fire escape ladders or

ther reliable means of escape from an upper floor in case stairs are

locked.

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

•

This combination Smoke/Carbon Monoxide Alarm has two separate alarms. The CO Alarm is not designed to detect fire or any other gas. It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The Smoke Alarm will only indicate the presence of smoke that reaches the sensor. The Smoke Alarm is not designed to sense gas, heat or flames.

INSTALLATION

WHERE TO INSTALL THIS ALARM

inimum coverage for Smoke Alarms, as recommended by the

ational Fire Protection Association (NFPA), is one Smoke Alarm on

very floor, in every sleeping area, and in every bedroom (See

“

Regulatory Information For Smoke Alarms” for details on the NFPA

ecommendations).

For 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.

In general, install combination Smoke and Carbon Monoxide Alarms:

•

On every level of your home, including finished attics and basements.

•

Inside every bedroom, especially if people sleep with the door partly

r completely closed.

• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is more than 12 meters (40 feet) long, install a unit at each end.

•

At the top of first-to-second floor stairs.

• At the bottom of the basement stairs.

• For additional coverage, install Alarms in all rooms, halls, and storage areas, where temperatures normally remain between 4.4 C and

37.8

C (40oF and 100oF).

Recommended Placement

•

When installing on the wall, the top edge of Smoke Alarms should

e placed between 102 mm (4 inches) and 305 mm (12 inches)

rom the wall/ceiling line.

•

When installing on the ceiling, place the alarm as close to the

enter as possible.

•

In either case, install at least 102 mm (4 inches) from where the

all and ceiling meet. See “Avoiding Dead Air Spaces” for more

nformation.

OTE: For any location, make sure no door or other obstruction could

eep carbon monoxide or smoke from reaching the Alarm.

nstalling Smoke/CO Alarms in Mobile Homes

or minimum security install one Smoke/CO Alarm as close to each

leeping area as possible. For more security, put one unit in each room.

any older mobile homes (especially those built before 1978) have little

r no insulation. If your mobile home is not well insulated, or if you are

nsure of the amount of insulation, it is important to install units on

nside walls only.

This equipment should be installed in accordance with CAN/ULC S553 or NFPA (National Fire Protection Association) 72 and

101. National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101 U.S.A. Additional local building and regulatory codes may apply in your area. Always check compliance requirements before beginning any installation.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Do NOT locate this Smoke/CO Alarm:

• In garages, kitchens, furnace rooms, crawl spaces and unfinished

attics. Avoid extremely dusty, dirty or greasy areas.

•

Where combustion particles are produced. Combustion particles

orm when something burns. Areas to avoid include poorly ventilated

itchens, garages, and furnace rooms. Keep units at least 6 meters (20 feet) from the sources of combustion particles (stove, furnace, water heater, space heater) if possible. In areas where a 6 meter (20-foot) distance is not possible – in modular, mobile, or smaller homes, for example – it is recommended the Smoke/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 Smoke/CO Alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible.

• Within 1.5 meters (5 feet) of any cooking appliance. In air streams near kitchens. Air currents can draw cooking smoke into the smoke sensor and cause unwanted alarms.

• In extremely humid areas. This Alarm should be at least 3 meters (10 feet) from a shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room, or other source of high humidity.

• In direct sunlight.

• In turbulent air, like near ceiling fans or open windows. Blowing air may prevent CO or smoke from reaching the sensors.

• In areas where temperature is colder than 4.4

C (40oF) or hotter than 37.8oC (100oF). These areas include non-airconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.

• In insect infested areas. Insects can clog the openings to the sensing chamber.

• Less than 305 mm (12 inches) away from fluorescent lights. Electrical “noise” can interfere with the sensor.

• In “dead air” spaces. See “Avoiding Dead Air Spaces”.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke/CO Alarm. To avoid dead air spaces, follow installation recommendations below. On ceilings, install Smoke/CO Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke/CO Alarm at least 102 mm (4 inches) from the wall or corner.

For wall mounting (if allowed by building codes), the top edge of Smoke/CO Alarms should be placed between 102 mm (4 inches) and 305 mm (12 inches) from the wall/ceiling line.

On a peaked, gabled, or cathedral ceiling, install the first Smoke/CO Alarm within 0.9 meters (3 feet) of the peak of the ceiling, measured horizontally. Additional Smoke/CO Alarms may be required depending on the length, angle, etc. of the ceiling's slope. Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.

larms have various limitations. See "General Limitations of

moke/CO Alarms" for details.

“SMART INTERCONNECT” FEATURE

This Alarm includes "Smart Interconnect" which enables the Alarm to be interconnected with other BRK Smoke, Heat, and "Smart Interconnect" CO Alarms. When smoke is detected, all Alarms will sound the smoke horn pattern. When CO is detected, "Smart Interconnect" Alarms will sound the CO horn pattern. Alarms that do not have the "Smart Interconnect" Feature will remain silent during a CO alarm.

If you hear the alarm horn sound 3 beeps, pause, 3 beeps and the RED SMOKE light is flashing, smoke has been detected. Evacuate everyone from the building.

Using the Optional Locking Features (Continued)

• Connect this unit ONLY to other compatible units. See “How To Install This Smoke/CO Alarm” for details. Do not connect it to any other type of alarm or auxiliary device. Connecting anything else to this unit may damage it or prevent it from operating properly.

• The battery compartment resists closing unless a battery is installed. This warns you the unit will not operate under DC power without a battery.

• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an emergency. Exposure to the horn at close range may harm your hearing.

• Do not paint over the unit. Paint may clog the openings to the sensing chambers and prevent the unit from operating properly.

Both locking features use locking pins, molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending on which locking features you use.

Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the green light once a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. The Alarm will continue to operate as long as AC power is supplied. Note, if battery is missing or dead, Low Battery Silence cannot be activated and alarm with continue to chirp approximately once per minute. However, replace the batteries

as soon as possible, to maintain protection in event of a power outage. 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).

To silence Alarms in an interconnected series:

To silence an interconnected series of Smoke/CO Alarms, you must press the Test/Silence button on the initiating alarm (The unit with the flashing red light; the red light will be off on all other Alarms.). If you press the Test/Silence on any other Alarm, it will only silence that unit, not the whole interconnected series.

When the Smoke Alarm is Silenced

When the CO Alarm is Silenced

The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.

If the smoke has not cleared–or continues to increase–the device will go back into alarm.

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.

SILENCING THE END OF LIFE SIGNAL

This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume.

In the case of a true unwanted alarm, use the Silence Feature (if equipped), open a window or fan the smoke away from the unit. The alarm will reset automatically when it returns to normal operation. Never remove the batteries from a battery operated unit to stop an unwanted alarm (caused by cooking smoke, etc.). Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.

“ALARM-MOVE TO FRESH AIR”

f 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!

WEEKLY TESTING

• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories of Canada

(ULC).

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. E

xposure at close range may be harmful to your hearing.

hen testing, step away when horn starts sounding.

t is important to test this unit every week to make sure it is working

roperly. Using the test button is the recommended way to test this

moke/CO Alarm.

. Push and hold the Test/Silence button on the cover until you hear a

“

chirp.” The “chirp” marks the start of the self-test sequence.

2. During testing, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps while the red smoke LED flashes. Then you will hear a loud, repeating horn pattern: 4 beeps, pause, 4 beeps, pause, while the red CO LED flashes.

. When testing a series of interconnected units you must test each

nit individually. Make sure all units alarm when each one is tested.

f the Smoke/CO Alarm does not test properly:

. Make sure the AC power is applied and battery is fresh and installed

correctly.

. Be sure the alarm is clean and dust-free.

. Test the unit again.

. If a Latch is set, the first TEST switch activation may be interpreted

s a "Clear Latch" signal.

If the Smoke/CO Alarm is still not working properly, replace it immediately. Refer to the “Limited Warranty” at the end of this manual.

f there is still a problem, do not try to fix the Alarm yourself.

his will void your warranty!

REGULAR MAINTENANCE

se only the replacement batteries listed below. The unit may not

perate properly with other batteries. Never use rechargeable

atteries since they may not provide a constant charge.

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:

•

Test it at least once a week.

• Clean the Smoke/CO Alarm at least once a month; gently vacuum the outside of the Smoke/CO Alarm using your household vacuum’s soft brush attachment. Test the Smoke/CO Alarm. Never use water, cleaners or solvents since they may damage the unit.

•

If the Smoke/CO Alarm becomes contaminated by excessive dirt,

ust and/or grime, and cannot be cleaned to avoid unwanted

larms, replace the unit immediately.

• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.

• When the battery back-up becomes weak, the Alarm will “chirp” about once a minute (the low battery warning). This warning should last 7 days, but you should replace the battery immediately to continue your protection. This Alarm must have AC or battery

power to operate. If AC power fails, and the battery is dead or missing, the Alarm cannot operate.

O NOT spray cleaning chemicals or insect sprays directly on or near

he Alarm. DO NOT paint over the Alarm. Doing so may permanently

amage the Alarm.

CHOOSING A REPLACEMENT BATTERY:

This Smoke/CO Alarm 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 9V lithium battery #U9VL for longer service life between battery changes. These batteries are available at many local retail stores.

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”). For any device employing a battery, constant exposure to high or low humidity may reduce battery life. Actual battery service life depends on the 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”).

Always use the exact batteries specified by this User ’s Manual. DO NOT use rechargeable batteries. Clean the battery contacts and also those of the device prior to battery installation. Install batteries correctly with regard to polarity (+ and -). Please dispose of or recycle used batteries properly, following any local regulations. Consult your local waste management authority or recycling organization to find an electronics recycling facility in your area. DO NOT DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.

Keep battery out of reach of children. In the event a battery is swallowed, immediately contact your poison control center, your physician, or the Canadian Battery Ingestion hotline at 1-416-813-5900 as seriou s injury may occur.

mproper use of appliance/device: operating a barbecue grill or

ehicle 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 f

ans.

• Several appliances running at the same time competing for limited f

resh 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 FROM CO POISONING?

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 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 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 all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO Alarm sounds.

ABOUT SMOKE ALARMS

Battery (DC) operated Smoke Alarms: Provide protection even when

electricity fails, provided the batteries are fresh and correctly installed. Units are easy to install, and do not require professional installation. However, they do not provide interconnected functionality.

AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. AC with battery (DC) back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.

Wireless Interconnected Alarms: Offer the same interconnected functionality as with hardwired alarms, without wires. Units are easy to install and do not require professional installation. They provide protection even when electricity fails, provided the batteries are fresh and correctly installed.

Smoke Alarms for Solar or Wind Energy users and battery backup power systems: AC powered Smoke Alarms should only be operated

with true or pure sine wave inverters. Operating this Smoke 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.

Smoke Alarms for the hearing impaired: Special purpose Smoke Alarms should be installed for the hearing impaired. They include a visual alarm and an audible alarm horn, and meet the requirements of the Americans With Disabilities Act. These units can be interconnected so if one unit senses smoke, all units alarm.

Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.

All these Smoke Alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual, and if smoke reaches the Alarm. If you are unsure which type of unit to install, refer to NFPA (National Fire Protection Association) 72 (National Fire Alarm Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101 U.S.A. Local building codes may also require specific units in new construction or in different areas of the home.

SPECIAL COMPLIANCE CONSIDERATIONS

This unit alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums, hotels, motels, dormitories, hospitals, long-term health care facilities, nursing homes, day care facilities, or group homes of any kind—even if they were once single-family homes. It is not a suitable substitute for complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire detection and alarm systems. Depending on the building codes in your area, this unit may be used to provide additional protection in these facilities.

The following information applies to all four types of buildings listed below:

n new construction, most building codes require the use of AC or

C/DC powered Smoke Alarms only. AC, AC/DC, or DC powered

moke Alarms can be used in existing construction as specified by local

uilding codes. Refer to NFPA 72 (National Fire Alarm Code) and NFPA

01 (Life Safety Code), local building codes, or consult your Fire

epartment for detailed fire protection requirements in buildings not

efined as “households.”

The End-of-Life Signal can be silenced for up to 2 days. Do not unplug the alarm or remove the batteries until you get replacement.

his Smoke/CO Alarm is intended for residential use. It is not intended

or use in industrial applications where Occupational Safety and Health

dministration (OSHA) requirements for Carbon Monoxide Alarms must

e met. The Smoke Alarm portion of this device is not intended to alert

earing impaired residents. Special purpose Smoke Alarms should be

nstalled for hearing impaired residents (CO Alarms are not yet available

or the hearing impaired).

moke/CO Alarms may not waken all individuals. Practice the

scape plan at least twice a year, making sure that everyone is involved

–

from kids to grandparents. Allow children to master fire escape

lanning and practice before holding a fire drill at night when they are

leeping. If children or others do not readily waken to the sound of the

moke/CO Alarm, or if there are infants or family members with mobility

imitations, make sure that someone is assigned to assist them in fire

rill and in the event of an emergency. It is recommended that you hold

fire drill while family members are sleeping in order to determine their

esponse to the sound of the Smoke/CO Alarm while sleeping and

o determine whether they may need assistance in the event of an

mergency.

moke/COAlarms cannot work without power.Battery operated units

annot work if the batteries are missing, disconnected or dead, if the wrong

ype of batteries are used, or if the batteries are not installed correctly.

C units cannot work if the AC power is cut off for any reason (open fuse

r circuit breaker, failure along a power line or at a power station, electrical

ire that burns the electrical wires, etc.). If you are concerned about the

imitations of battery or AC power, install both types of units.

This Smoke/CO Alarm will not sense smoke or CO that does not reach the sensors. It will only sense smoke or CO at the sensor. Smoke

or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or smoke reaches the sensors. If bedroom doors are usually closed at night, we recommend you install an alarm device (Combination CO and Smoke Alarm, or separate CO Alarms and Smoke Alarms) in each bedroom and in the hallway between them.

This Smoke/CO Alarm may not sense smoke or CO on another level of the home. Example: This alarm device, installed on the second

floor, may not sense smoke or CO in the basement. For this reason, one alarm device may not give adequate early warning. Recommended minimum protection is one alarm device in every sleeping area, every bedroom, and on every level of your home. Some experts recommend battery powered Smoke and CO Alarms be used in conjunction with interconnected AC powered Smoke Alarms. For details, see “About Smoke Alarms” for details.

This carbon monoxide alarming device is designed to detect carbon monoxide gas from ANY source of combustion. It is NOT designed

to detect smoke, fire, or any other gases.

moke/CO Alarms may not be heard. The alarm horn loudness

eets or exceeds current standards of 85 dB at 3 meters (10 feet).

owever, if the Smoke/CO Alarm is installed outside the bedroom, it

ay 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 Smoke/CO Alarm is not intended for people who are hearing impaired.

The Alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke from some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children playing with matches, or fires caused by violent explosions resulting from escaping gas.

This Smoke/CO Alarm is not a substitute for life insurance.

Though this Smoke/CO Alarm warns against increasing CO levels or the presence of smoke, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives.

This Smoke/CO Alarm has a limited life. Although this Smoke/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 this device weekly. The unit should be replaced immediately if it is not operating properly.

This Smoke/CO Alarm is not foolproof. Like all other electronic devices, this Smoke/CO Alarm has limitations. It can only detect smoke or CO that reaches the sensors. It may not give early warning of the source of smoke or CO is in a remote part of the home, away from the alarm device.

LATCHING FEATURES

larm Latch is activated after an Alarm is exposed to alarm levels of

moke or carbon monoxide. After smoke or CO levels drop below alarm

evels, the “Smoke/Power” or “CO” Red LED will begin to flash On 2 s

econds/Off 2 seconds. It will continue to flash or “latch” until you clear

t by testing the alarm. T

his feature helps emergency responders, investigators, or service

echnicians identify which unit(s) in your home were exposed to alarm

evels of smoke or carbon monoxide. This can help investigators p

inpoint the source of smoke or CO.

nterconnected Alarms. Latching Alarm Indicator shows which Alarm(s)

n the series were exposed to alarm levels of smoke or carbon monoxide. T

he Latching Alarm Indicator stays ON until you clear it, so it can alert

ou to an alarm that occurred while you were away from home, even

hough smoke or CO present in the air has dropped below alarm levels.

Low Battery Latch is activated when the Alarm is in the "low battery condition". When this occurs, the Smoke/Power LED flashes Green On for 2 seconds/Off for 2 seconds. 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.

F YOUR SMOKE/CO ALARM SOUNDS, Continued

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.

ommon appliances are often sources of CO. If they are not properly

aintained, are improperly ventilated, or malfunction, CO levels can rise

uickly. CO is a real danger now that homes are more energy efficient.

“

Air-tight” homes with added insulation, sealed windows, and other

eatherproofing can “trap” CO inside.

SYMPTOMS OF CO POISONING

The following symptoms may be related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household:

Mild Exposure: Headaches, running nose, sore eyes, often described as “flu”-like symptoms.

Medium Exposure: Dizziness, drowsiness, vomiting. Extreme Exposure: Unconsciousness, brain damage, death.

Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance.

his CO Alarm measures exposure to CO over time. It alarms if CO

evels 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

ounds an alarm before the onset of symptoms in average, healthy

dults.

hy is this important? Because you need to be warned of a potential

O problem while you can still react in time. In many reported cases of

O exposure, victims may be aware that they are not feeling well, but

ecome disoriented and can no longer react well enough to exit the

uilding or get help. Also, young children and pets may be the first

ffected. The average healthy adult might not feel any symptoms when

he CO Alarm sounds. However, people with cardiac or respiratory

roblems, infants, unborn babies, pregnant mothers, or elderly people

an be more quickly and severely affected by CO. If you experience

ven mild symptoms of CO poisoning, consult your doctor immediately!

This device is designed to protect individuals from the acute effects of carbon monoxide exposure. It will not fully safeguard individuals with specific medical conditions. If in doubt consult a medical practitioner.

FINDING THE SOURCE OF CO AFTER AN ALARM

arbon monoxide is an odorless, invisible gas, which often makes it

ifficult to locate the source of CO after an alarm. These are a few of

he 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.

ecause CO may dissipate by the time an investigator arrives, it may

e difficult to locate the source of CO. BRK Brands, Inc. shall not be

bligated to pay for any carbon monoxide investigation or service

all.

REGULATORY INFORMATION FOR SMOKE/CO A

LARMS

EGULATORYINFORMATION FOR CO ALARMS

CANADIAN STANDARDS ASSOCIATION What Levels of CO Cause an Alarm?

CSA 6.19 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).

SA 6.19 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 B

ETWEEN 10 and 50 MINUTES.

• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.

*Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH).

he unit is designed not to alarm when exposed to a constant level

f 30 ppm for 30 days.

O Alarms are designed to alarm before there is an immediate life threat.

ince 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: CSA 6.19

Audible Alarm: 85 dB minimum at 3 meters (10 feet).

ECOMMENDED LOCATIONS FOR SMOKE ALARMS

nstalling Smoke Alarms in Single-Family Residences

The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See “Agency Placement Recommendations” for details. F

or additional coverage, it is recommended that you install a Smoke

larm in all rooms, halls, storage areas, finished attics, and basements,

here temperatures normally remain between 4

(40

) and 38

(

100

). Make sure no door or other obstruction could keep smoke from

eaching the Smoke Alarms.

ore specifically, install Smoke Alarms:

•

On every level of your home, including finished attics and basements.

•

Inside every bedroom, especially if people sleep with the door partly

r completely closed.

•

In the hall near every sleeping area. If your home has multiple

leeping areas, install a unit in each. If a hall is more than 12 meters

(

40 feet long), install a unit at each end.

• At the top of the first-to-second floor stairway, and at the bottom of

the basement stairway.

Specific requirements for Smoke Alarm installation vary from state to state and from region to region. Check with your local Fire Department for current requirements in your area. It is recommended AC or AC/DC

units be interconnected for added protection.

AGENCY PLACEMENT RECOMMENDATIONS

NFPA 72 (National Fire Code) Chapter 11

“

For your information, the National Fire Protection Association's

tandard 72, reads as follows:”

“

11.5.1 One- and Two-Family Dwelling Units.”

“11.5.1.1 Smoke Detection. Where required by applicable laws, codes,

or standards for the specified occupancy, approved single- and multiplestation Smoke Alarms shall be installed as follows: (1) In all sleeping rooms. Exception: Smoke Alarms shall not be required in sleeping rooms in existing one- and two-family dwelling units. (2) Outside of each separate sleeping area, in immediate vicinity of the sleeping rooms. (3) On each level of the dwelling unit, including basements. Exception: In existing one- and two family dwelling units, approved Smoke Alarms powered by batteries are permitted.”

“A.11.8.3 Are More Smoke Alarms Desirable?

The required number of Smoke Alarms might not provide reliable early warning protection for those areas separated by a door from the areas protected by the required Smoke Alarms. For this reason, it is recommended that the householder consider the use of additional Smoke Alarms for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not protected by the required Smoke Alarms. The installation of Smoke Alarms in kitchens, attics (finished or unfinished), or garages is not normally recommended, as these locations occasionally experience conditions that can result in improper operation.”
