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.

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

For additional coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas, finished attics, and basements, where tempera- tures normally remain between 40˚ F (4˚ C) and 100˚ F (38˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.

More 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 or 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 40 feet long (12 meters), 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 inter- connected for added protection.

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.

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.

Smoke/CO Alarms for Solar or Wind Energy users and battery backup power systems: AC powered Smoke/CO Alarms should only be operated with true or pure sine wave inverters. Operating this Alarm with most battery- powered UPS (uninterruptible power supply) products or square wave or “quasi sine wave” inverters will damage the Alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.

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. 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 Smoke Alarm to install, refer the National Fire Protection Association (NFPA) Standard 72 (National Fire Alarm Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.

WHERE TO INSTALL THIS ALARM, Continued

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.

NOTE: For added protection, install an additional Smoke/CO Alarm at least

15 feet (4.6 meters) away from the furnace or fuel burning heat source where possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the Alarm as far away as possible from the furnace or other fuel burning source. Installing the Alarm closer than 15 feet (4.6 meters) will not harm the Alarm, but may increase the frequency of unwanted alarms.

HOW TO INSTALL THIS ALARM

This combination Smoke/CO Alarm was designed to be mounted on the ceiling or wall. It is not a tabletop device. You must install this device on the ceiling or wall as outlined below. Read “Where To Install This Alarm” before starting.

PARTS OF THIS SMOKE/CO ALARM

1 Test/Silence Button

2 Battery Compartment

3 Power/Smoke Alarm LED

4 CO Alarm LED

Tools you will need: pencil, drill with 3/16” or 5mm drill bit, flathead screwdriver, hammer.

•Do not connect this unit to any other alarm or auxiliary device. It is a single-station unit that cannot be linked to other devices. Connecting anything else to this unit may prevent it from working properly.

•Do not install this unit over an electrical junction box. Air currents around junction boxes can prevent smoke from reaching the sens- ing chamber and prevent the unit from alarming. Only AC powered units are intended for installation over junction boxes.

REGULAR MAINTENANCE

This unit has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it working properly.

Use only the replacement batteries listed below. The unit may not operate properly with other batteries. Never use rechargeable batteries since they may not provide a constant charge.

•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. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer instructions for use. 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, dust and/or grime, and cannot be cleaned to avoid unwanted alarms, replace the unit immediately.

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

Choosing a replacement battery:

Your Smoke/CO Alarm requires two standard AA batteries. It was shipped with two AA batteries. The following batteries are acceptable as replacements: Eveready Energizer E91. These batteries are available at many local retail stores.

Actual battery service life depends on the Smoke/CO Alarm and the environ- ment 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

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.

•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 OR RECREATIONAL VEHICLE

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

INSTALLING SMOKE ALARMS IN MOBILE HOMES

For minimum security install one Smoke Alarm as close to each sleeping area as possible. For more security, put one unit in each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only. Smoke Alarms should be installed where temperatures normally remain between 40˚ F (4˚ C) and 100˚ F (38˚ C).

AGENCY PLACEMENT RECOMMENDATIONS

This equipment should be installed in accordance with NFPA (National Fire Protection Association) 72 and 101. National Fire Protection Association,

One Batterymarch Park, Quincy, MA 02269-9101. Additional local building and regulatory codes may apply in your area. Always check compliance requirements before beginning any installation.

Standards: Underwriters Laboratories Inc. Single and Multiple Station Smoke Alarms 217.

NFPA 72 (National Fire Code)

Smoke Alarms shall be installed in each separate sleeping room, outside each sleeping area in the immediate vicinity of the bedrooms and on each additional story of the family living unit, including basements and excluding crawl spaces and unfinished attics.

In new construction, Alarms shall be so arranged that operation of any one Alarm shall cause the operation of all Alarms within the dwelling.

Smoke Detection-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.

California State Fire Marshal (CSFM)

Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A Smoke Alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.

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 five types of buildings listed below:

In new construction, most building codes require the use of AC or AC/DC powered Smoke Alarms only. AC, AC/DC, or DC powered Smoke Alarms can be used in existing construction as specified by local building codes. Refer to NFPA 72 (National Fire Alarm Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households.”

1.Single-Family Residence: Single family home, townhouse. It is recommend- ed this unit be installed on every level of the home, in every bedroom, and in each bedroom hallway.

2.Multi-Family or Mixed Occupant Residence: Apartment building, condominium. This unit is suitable for use in individual apartments or condos, provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or porches. Using this unit in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.

3.Institutions: Hospitals, day care facilities, long-term health care facilities. This unit is suitable for use in individual patient sleeping/resident rooms, provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or porches. Using this unit in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.

4.Hotels and Motels: Also boarding houses and dormitories. This unit is suitable for use inside individual sleeping/resident rooms, provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or porches. Using this unit in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.

5.Warehouses/Commercial Buildings: DO NOT use this Smoke/CO Alarm in warehouses, industrial or commercial buildings, special-purposenon-resi- dential buildings, or airplanes. This Smoke/CO Alarm is specifically designed for residential use, and may not provide adequate protection in other applications.

All First Alert® Smoke Alarms conform to regulatory requirements, including UL217 and are designed to detect particles of combustion. Smoke particles of varying number and size are produced in all fires.

Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which tend to be produced in greater amounts by flaming fires, which consume combustible

refer to national and local codes ￿ before beginning any installation.

In new construction AC and AC/DC smoke alarms MUST be interconnected to meet NFPA recommendations.

•When installing on the wall, the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.

•When installing on the ceiling, place the alarm as close to the center as possible.

•In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.

NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the Alarm.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Do NOT locate this Smoke/CO Alarm:

•Avoid 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, RVs, or smaller homes, for example – it is recommended the Smoke 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 Alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible.

•Within 5 feet (1.5 meters) 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 10 feet (3 meters) 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 insect infested areas. Insects can clog the openings to the sensing chamber.

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

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

AVOIDING DEAD AIR SPACES

If you want to lock the battery compartment, or lock the Smoke/CO Alarm to the mounting bracket, please read the “Optional Locking Features” section.

1.Hold base firmly and twist the mounting bracket counterclockwise (left) to separate it from the unit.

2.Hold the mounting bracket against the ceiling (or wall) so the vertical mounting slot is aligned in the 12 o’clock position and trace around the inside of the mounting slots (vertical and horizontal mounting).

3.Put the unit where it won’t get covered with dust when you drill the mounting holes.

4.Using a 3/16” (5 mm) drill bit, drill a hole through the center of the oval outlines you traced.

5.Insert the plastic screw anchors (in the plastic bag with screws) into the holes. Tap the screw anchors gently with a hammer, if necessary, until they are flush with the ceiling or wall.

6.Line the mounting bracket up over the plastic screw anchors.

7.Screw the mounting bracket to the ceiling or wall through the mounting slots using the two screws provided.

8.Before attaching the Alarm to

the bracket, insert the two (2) AA batteries (included) into the battery compartment. Match the terminals on the end of the battery with the terminals on the unit. Match “+” to “+” and “-” to “-.” If the batteries are not fully inserted, the unit cannot receive battery power.

NOTE: The unit may beep briefly when you install the batteries. This is normal. The GREEN Light flashes about every 60 seconds when the unit is receiving battery power.

The battery door will resist closing unless batteries are installed. This warns you the unit will not operate without batteries.

9. Attach the Smoke/CO Alarm to the mounting bracket. Line up the guides on the alarm’s base with the guides on the mounting bracket. When guides are lined up, turn the base clockwise (right) until it snaps into place.

NOTE: Once the Smoke/CO Alarm is

“chirping” (the “low battery warning”).

To replace the batteries (without removing

“ALARM-MOVE TO FRESH AIR”

If you hear the CO alarm horn and the CO red light is flashing, move everyone to a source of fresh air. DO NOT remove the batteries!

Actuation of your CO Alarm indicates the presence of carbon monoxide (CO) which can kill you. In other words, when your CO Alarm sounds, you must not ignore it!

IF THE CO ALARM SIGNAL SOUNDS:

1.	Operate the Test/Silence button.
2.	Call your emergency services, fire department or 911. Write down the
	number of your local emergency service here:

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.

This Smoke/CO Alarm is intended for RV or residential use. It is not intended for use in industrial applications where Occupational Safety and Health Administration (OSHA) requirements for Carbon Monoxide Alarms must be met. The Smoke Alarm portion of this device is not intended to alert hearing impaired residents. Special purpose Smoke Alarms should be installed for hearing impaired residents (CO Alarms are not yet available for the hearing impaired).

Smoke/CO Alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not readily waken to the sound of the Smoke/CO Alarm, or if there are infants or family members with mobility limitations, make sure that someone

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.

Smoke/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 Smoke/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,

Photoelectric technology is generally more sensitive than ionization technology at detecting large particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours

before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on each level and in every bedroom of your home.

INTRODUCTION

FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations: 1) Use smoking materials properly. Never smoke in bed. 2) Keep matches or lighters away

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 4 inches (102 mm) from the wall or corner.

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

On a peaked, gabled, or cathedral ceiling, install first Smoke/CO Alarm within 3 feet (0.9 meters) 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.

10. Test the Smoke/CO Alarm. See “Weekly Testing” for details.

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 investi-

gate 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:

__________________________________________________________________

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.

is assigned to assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine their response to the sound of the Smoke/CO Alarm while sleeping and to determine whether they may need assistance in the event of an emergency.

Smoke/CO Alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected or dead, if the wrong type of bat- teries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the electrical wires, etc.). If you are concerned about the limitations 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

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.

from children; 3) Store flammable materials in proper containers; 4) Keep electrical appliances in good condition and don’t overload electrical circuits;

5)Keep stoves, barbecue grills, fireplaces and chimneys grease- and debris- free; 6) Never leave anything cooking on the stove unattended; 7) Keep portable heaters and open flames, like candles, away from flammable materials; 8) Don’t let rubbish accumulate.

Keep alarms clean, and test them weekly. Replace alarms immediately if they are not working properly. Smoke Alarms that do not work cannot alert you to a fire. Keep at least one working fire extinguisher on every floor, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper floor in case stairs are blocked.

BASIC SAFETY INFORMATION

• Dangers, Warnings, and Cautions alert you to important operating

instructions or to potentially hazardous situations. Pay special

attention to these items.

OPTIONAL LOCKING FEATURES

The optional locking features are designed to discourage unauthorized removal of the batteries or Alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or Alarm removal is not a concern.

This Smoke/CO Alarm has two separate locking features: one to lock the battery compartment, and the other to lock the Smoke/CO Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.

Tools you will need: • Needle-nose pliers or utility knife • Standard flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking features you use, remove one or both pins from the mounting bracket using needle-nose pliers or a utility knife.

To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.

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 replace- ment of heating, ventilation, air conditioning (HVAC) equipment, combustion appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.”

RESPONDING TO AN ALARM

•	If the unit alarms and you are not testing the unit, it is warning you
	of a potentially dangerous situation that requires your immediate
	attention. NEVER ignore any alarm. Ignoring the alarm may result in
	injury or death.
•	Never remove the batteries from a battery operated Smoke/CO Alarm

• 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

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.

• 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

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you activate the battery and test the Smoke/CO Alarm.

TO UN-LOCK THE BATTERY COMPARTMENT

1. Remove the Smoke/CO Alarm from the mounting bracket. If the unit is locked to the bracket, see the section “To Un-Lock the Mounting Bracket.”

to stop an unwanted alarm (caused by cooking smoke, etc.). Removing

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.

REGULATORY INFORMATION FOR

SMOKE/CO ALARMS

REGULATORY INFORMATION FOR CO ALARMS

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 if CO, IT MUST ALARM BETWEEN

60 and 240 MINUTES.

* Approximately 10% COHb exposure at levels of 10% to 95% Relative

Humidity (RH).

flames.

• This Smoke/CO Alarm cannot operate without working batteries.

Removing the batteries for any reason, or failing to replace the

batteries at the end of their service life, removes your protection.

• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds”

for more information on how to respond to an alarm. Failure to

respond can result in injury or death.

• The Silence Features are for your convenience only and will not

correct a problem. See "Using the Silence Features" for details.

Always check your home for a potential problem after any alarm.

Failure to do so can result in injury or death.

• Test this Smoke/CO Alarm once a week. If the Alarm ever fails to

test correctly, have it replaced immediately! If the Alarm is not

working properly, it cannot alert you to a problem.

• This product is intended for use in ordinary indoor locations of

family living units or in RVs. It is not designed to measure CO levels

in compliance with Occupational Safety and Health Administration

(OSHA) commercial or industrial standards. Individuals with medical

conditions that may make them more sensitive to carbon monoxide

may consider using warning devices which provide audible and

visual signals for carbon monoxide concentrations under 30 ppm.

1.	Install the batteries before attaching the Alarm
	to the bracket. Insert the two (2) AA batteries
	(included) into the battery compartment. Match
	the terminals on the end of the battery with the
	terminals on the unit. Match “+” to “+” and “-”
	to “-.” If the batteries are not fully inserted, the
	unit cannot receive battery power.
2.	Push and hold Test/Silence button until the
	alarm sounds.

If the unit does not alarm during testing, DO NOT lock the battery compartment! Install new batteries and test again. If the unit still does not alarm, replace it immediately.

3.Using needle-nose pliers or a utility knife, detach one locking pin from the mounting bracket.

4.Push the locking pin through the hole near the battery door latch on the back of the Smoke/CO Alarm.

2. Insert a flathead screwdriver under the head of the locking pin, and gently pry it out of the battery compartment lock. (If you plan to re-lock the battery compartment, save the locking pin.)

3. To re-lock the battery compartment, close the battery door and reinsert locking pin in lock.

4. Reattach the Smoke/CO Alarm to the mounting bracket.

When replacing the batteries, always test the Smoke/CO Alarm before re-locking the battery compartment.

•Don’t panic; stay calm. Follow your family escape plan.

•Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.

•Feel doors with the back of your hand before opening them.

If a door is cool, open it slowly. Don’t open a hot door. Keep doors and windows closed, unless you must escape through them.

•Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.

•Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.

•Call the Fire Department as soon as possible from outside. Give your address, then your name.

•Never go back inside a burning building for any reason.

•Contact your Fire Department for ideas on making your home safer.

Alarms have various limitations. See "General Limitations of Smoke/CO Alarms" for details.

USING THE SILENCE FEATURES

Never remove the batteries to quiet an unwanted alarm. Removing the batteries disables the alarm and removes your protection.

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.

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 THIS ALARM

Installing Combination Smoke/CO Alarms in Recreational Vehicles or Mobile Homes

For minimum security, a combination Smoke/CO Alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. For more security, install additional Alarms in each separate bedroom. The Alarm should be located at least 6 inches (152 mm) from all exterior walls and at least 3 feet (0.9 meters) from supply or return vents.

Test units used in RVs after the vehicle has been in storage, before each trip, and once a week while in use. Failure to test units used in RVs as described may remove your protection.

In general, install residential combination Smoke/CO Alarms:

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

•Inside every bedroom, especially if people sleep with the door partly or 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 40 feet (12 meters) 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 40˚ F and 100˚ F (4˚ C and 38˚ C).

Minimum coverage for Smoke Alarms, as recommended by the National Fire Protection Association (NFPA), is one Smoke Alarm on every floor, in every sleeping area, and in every bedroom (See “Regulatory Information For Smoke Alarms” for details on the NFPA recommendations).
