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

INSTALLATION  
WHERE TO INSTALL THIS ALARM  
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).  
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.  
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  
materials rapidly and spread quickly. Sources of these fires may include  
paper burning in a wastebasket, or a grease fire in the kitchen.  
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.  
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 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).

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.  
TO LOCK THE BATTERY COMPARTMENT  
TO UNLOCK THE BATTERY COMPARTMENT  
Do not lock the battery compartment until you  
activate the battery and test the Smoke/CO

3. When you attach the Smoke/CO Alarm to  
the mounting bracket, the locking pin’s  
head will fit into a notch on the bracket.  
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, Inc. (UL). NEVER use vehicle exhaust!  
Exhaust may cause permanent damage and voids your warranty.  
You can test this Smoke/CO Alarm: Press and hold the Test/Silence button  
3-5 seconds until unit starts to alarm.  
During testing, you will see and hear the following sequence:  
• The Horn will sound 3 beeps, pause, 3 beeps. The Power/Smoke LED  
flashes Red and the CO LED will be Off.  
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Power/Smoke  
LED will be Off and the CO LED flashes Red.  
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.  
If the unit does not alarm, make sure the batteries are correctly installed,  
and test again. If the unit still does not alarm, replace it immediately.  
It is important to test this unit every week to make sure it is working  
properly. Using the test button is the recommended way to test this  
Smoke/CO Alarm.

IF THE SMOKE ALARM SOUNDS  
RESPONDING TO AN ALARM  
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.  
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 to stop an unwanted alarm (caused by cooking smoke, etc.).  
Removing batteries disables the alarm so it cannot sense smoke,  
and removes your protection. Instead open a window or fan the  
smoke away from the unit. The alarm will reset automatically.  
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 unit alarms get everyone out of the house immediately.  
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.  
WHAT TO DO IN CASE OF FIRE  
• 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.  
Choosing a replacement battery:  
Your Smoke/CO Alarm requires two standard AA batteries. The following  
batteries are acceptable as replacements: Eveready Energizer E91. These  
batteries are available at many local retail stores.  
• 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.  
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  
“chirping” (the “low battery warning”).  
To replace the batteries (without removing  
Alarm from the ceiling or wall):  
1. Open the battery compartment.  
2. Press tabs A and B as shown in the diagram  
and remove each battery.  
Alarms have various limitations. See "General Limitations of Smoke/CO  
Alarms" for details.  
3. Insert the new batteries, making sure they  
B
USING THE SILENCE FEATURES  
A
snap completely into the battery compartment.  
Match the terminals on the ends of the  
batteries with the terminals on the unit.  
Never remove the batteries to quiet an unwanted alarm. Removing the  
batteries disables the alarm and removes your protection.  
The Silence Feature is intended to temporarily silence the horn while you identify  
and correct the problem. Do not use the Silence Feature in emergency situations.  
It will not correct a CO problem or extinguish a fire.  
4. Close the battery compartment, and then test  
the unit by pressing the Test/Silence button.  
The Silence Feature can temporarily quiet an unwanted alarm for several minutes.  
Press the Test/Silence button on the alarm cover for at least 3-5 seconds.

SILENCING THE LOW BATTERY WARNING  
IF THE CO ALARM SOUNDS  
“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!  
This silence feature can temporarily quiet the low battery warning “chirp” for up  
to 8 hours. Press the Test/Silence button on the alarm cover.  
Once the low battery warning “chirp” silence feature is activated, the unit  
continues to flash the Green light twice a minute for 8 hours. After 8 hours, the  
low battery “chirp” will resume. Replace the batteries as soon as possible;  
this unit will not operate without battery power!  
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!  
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).  
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. Immediately move to fresh air—outdoors or by an open door or window.  
Do a head count to check that all persons are accounted for. Do not re-  
enter the premises, or move away from the open door or window until the  
emergency services responder has arrived, the premises have been aired  
out, and your CO Alarm remains in its normal condition.  
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour  
period, repeat steps 1-3 and call a qualified appliance technician to inves-  
tigate 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:  
NOTE: A qualified appliance technician is defined as “a person, firm, corporation,  
or company that either in person or through a representative, is engaged in and  
responsible for the installation, testing, servicing, or replacement of heating,  
ventilation, air conditioning (HVAC) equipment, combustion appliances and  
equipment, and/or gas fireplaces or other decorative combustion equipment.”

WHAT YOU NEED TO KNOW ABOUT CO  
HOW CAN I PROTECT MY FAMILY FROM  
CO POISONING?  
WHAT IS CO?  
A CO Alarm is an excellent means of protection. It monitors the air and sounds  
a loud alarm before Carbon Monoxide levels become threatening for average,  
healthy adults.  
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.  
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:  
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,  
kerosene, and propane.  
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.  
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.  
Test and maintain all fuel-burning equipment annually. Many local gas  
or oil companies and HVAC companies offer appliance inspections for  
a nominal fee.  
SYMPTOMS OF CO POISONING  
These symptoms are related to CO POISONING and should be discussed  
with ALL household members.  
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.  
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 mini-  
mum 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!  
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.  
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).  
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 diffi-  
cult to locate the source of CO. BRK Brands, Inc. shall not be obligated to  
pay for any carbon monoxide investigation or service call.  
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.  
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.  
* Approximately 10% COHb exposure at levels of 10% to 95% Relative  
Humidity (RH).  
The unit is designed not to alarm when exposed to a constant level  
of 30 ppm for 30 days.  
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.  
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.  
Improper use of appliance/device:  
operating a barbecue grill or vehicle  
in an enclosed area (like a garage or  
screened porch).  
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.  
Transient CO Problems: “transient” or on-again-off-again CO problems can  
be caused by outdoor conditions and other special circumstances.  
Standards: Underwriters Laboratories Inc. Single and Multiple Station carbon  
monoxide alarms UL2034.  
The following conditions can result in transient CO situations:  
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.  
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.  
Audible Alarm: 85 dB minimum at 10 feet (3 meters).  
REGULATORY INFORMATION FOR SMOKE ALARMS  
RECOMMENDED LOCATIONS FOR SMOKE ALARMS  
Installing Smoke Alarms in Single-Family Residences  
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.  
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.

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.  
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.  
More specifically, install Smoke Alarms:  
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.  
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.  
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.  
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.  
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.  
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.  
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).  
The following information applies to all five types of buildings listed below:  
AGENCY PLACEMENT RECOMMENDATIONS  
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.”  
Standards: Underwriters Laboratories Inc. Single and Multiple Station Smoke  
Alarms 217.  
NFPA 72 (National Fire Code) Chapter 11  
“For your information, the National Fire Protection Association's Standard 72,  
reads as follows:”  
1. Single-Family Residence: Single family home, townhouse. It is recom-  
mended this unit be installed on every level of the home, in every bedroom,  
and in each bedroom hallway.  
“11.5.1 One- and Two-Family Dwelling Units.”  
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.  
“11.5.1.1 Smoke Detection. Where required by applicable laws, codes, or  
standards for the specified occupancy, approved single- and multiple-station  
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.”  
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.  
“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.”  
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.  
California State Fire Marshal (CSFM)  
5. Warehouses/Commercial Buildings: DO NOT use this Smoke/CO Alarm in  
warehouses, industrial or commercial buildings, special-purpose non-residen-  
tial buildings, RVs, boats, or airplanes. This Smoke/CO Alarm is specifically  
designed for residential use, and may not provide adequate protection in  
non-residential applications.  
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.  
GENERAL LIMITATIONS OF SMOKE/CO ALARMS  
This Smoke/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 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 resi-  
dents (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  
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.

GENERAL LIMITATIONS OF SMOKE/CO ALARMS, Continued  
Smoke/CO Alarms cannot work without power. Battery operated units cannot  
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, 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.  
work if the batteries are missing, disconnected or dead, if the wrong type of  
batteries 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 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 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.  
TROUBLESHOOTING GUIDE  
If the Alarm...
