BRK electronic Smoke Alarm SCO5RV User Manual

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:

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.  
WHAT YOU NEED TO KNOW ABOUT CO  
HOW TO INSTALL THIS ALARM  
REGULAR MAINTENANCE  
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.  
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.  
USER’S MANUAL  
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.  
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.  
COMBINATION CARBON MONOXIDE & SMOKE ALARM  
FOR RECREATIONAL VEHICLE USE  
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.  
On every level of your home, including finished attics and basements.  
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.  
Inside every bedroom, especially if people sleep with the door partly or  
completely closed.  
Test it at least once a week.  
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.  
Clean the Smoke/CO Alarm at least once a month; gently vacuum the  
outside of the Smoke/CO Alarm using your household vacuums 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.

KEY:  
SMOKE ALARMS  
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.  
SMOKE ALARM WITH  
SILENCE FEATURE  
All these Smoke Alarms are designed to provide early warning of fires if located,  
installed and cared for as described in the users 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.  
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.  
This CO Alarm measures exposure to CO over time. It alarms if CO levels  
are extremely high in a short period of time, or if CO levels reach a certain  
minimum over a long period of time. The CO Alarm generally sounds an alarm  
before the onset of symptoms in average, healthy adults. Why is this important?  
Because you need to be warned of a potential CO problem while you can still  
react in time. In many reported cases of CO exposure, victims may be aware  
that they are not feeling well, but become disoriented and can no longer react  
well enough to exit the building or get help. Also, young children and pets may  
be the first affected. The average healthy adult might not feel any symptoms  
when the CO Alarm sounds. However, people with cardiac or respiratory  
problems, infants, unborn babies, pregnant mothers, or elderly people can  
be more quickly and severely affected by CO. If you experience even mild  
symptoms of CO poisoning, consult your doctor immediately!

use by others, you must leave this manual—or a copy  
of it—with the end user.  
BOTH, OR COMBINATION  
SMOKE/CO ALARMS  
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.  
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 manufacturers suggested  
battery life, you MUST replace the battery immediately once the unit starts  
“chirping” (the “low battery warning”).  
Suggested locations are based on  
NFPA recommendations (NFPA 72  
for Smoke Alarms and NFPA 720 for  
Carbon Monoxide Alarms). Always  
refer to national and local codes  
Model SCO5RV  
before beginning any installation.  
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.  
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.

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:  
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).  
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).  
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.  
3. Insert the new batteries, making sure they

batteries with the terminals on the unit.  
3. Put the unit where it won’t get covered with dust when you drill the  
mounting holes.  
4. Close the battery compartment, and then test  
NOTE: For any location, make sure no door or other obstruction could keep  
carbon monoxide or smoke from reaching the Alarm.  
the unit by pressing the Test/Silence button.  
4. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the oval  
outlines you traced.  
The following information applies to all five types of buildings listed below:  
AGENCY PLACEMENT RECOMMENDATIONS  
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.  
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-purpose non-resi-  
dential buildings, or airplanes. This Smoke/CO Alarm is specifically designed  
for residential use, and may not provide adequate protection in other  
applications.  
WHERE THIS ALARM SHOULD NOT BE INSTALLED  
Do NOT locate this Smoke/CO Alarm:  
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.  
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.

IF YOUR SMOKE/CO ALARM SOUNDS  
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM  
Avoid extremely dusty, dirty or greasy areas.  
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.  
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.  
6. Line the mounting bracket up over the plastic screw anchors.

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.  
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.

The following conditions can result in transient CO situations:  
1. Excessive spillage or reverse venting of fuel appliances caused by outdoor  
conditions such as:  
In direct sunlight.  
The battery door will resist closing unless batteries are installed. This  
warns you the unit will not operate without 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!  
In turbulent air, like near ceiling fans or open windows. Blowing air may  
prevent CO or smoke from reaching the sensors.  
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.  
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.  
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.

All First Alert Smoke Alarms conform to regulatory requirements,  
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,

2. Call your emergency services, fire department or 911. Write down the  
number of your local emergency service here:  
Vent pipe connections vibrating loose from clothes dryers, furnaces, or  
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.  
In “dead air” spaces. See “Avoiding Dead Air Spaces.  
water heaters.  
__________________________________________________________________  
Obstructions in or unconventional vent pipe designs which can amplify  
the above situations.  
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.  
NOTE: Once the Smoke/CO Alarm is  
snapped onto the mounting bracket,  
you can rotate the Smoke/CO Alarm  
to adjust the alignment.  
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 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:  
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.  
GENERAL LIMITATIONS OF SMOKE/CO ALARMS  
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.  
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  
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  
Alarm, or separate CO Alarms and Smoke Alarms) in each bedroom and in the  
hallway between them.  
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,  
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.  
10. Test the Smoke/CO Alarm. See “Weekly Testing” for details.  
For maximum protection, use both types of Smoke Alarms on each level  
and in every bedroom of your home.

CO POISONING?  
INTRODUCTION  
FIRE SAFETY TIPS  
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.  
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.  
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:  
__________________________________________________________________  
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.”  
OPTIONAL LOCKING FEATURES  
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.  
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.  
Test and maintain all fuel-burning equipment annually. Many local gas or  
oil companies and HVAC companies offer appliance inspections for a  
nominal fee.  
Tools you will need: • Needle-nose pliers or utility knife • Standard flathead screwdriver.  
IF THE SMOKE ALARM SOUNDS  
RESPONDING TO AN ALARM  
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.  
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.  
BASIC SAFETY INFORMATION  
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.  
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.  
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.  
• Dangers, Warnings, and Cautions alert you to important operating  
instructions or to potentially hazardous situations. Pay special  
attention to these items.  
TO LOCK THE BATTERY COMPARTMENT  
TO UN-LOCK THE BATTERY COMPARTMENT  
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.  
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  
Do not lock the battery compartment until you  
activate the battery and test the Smoke/CO  
Alarm.  
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.”  
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.  
Check the house or garage on the other side of shared wall.  
If the unit alarms get everyone out of the house immediately.  
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.  
WHAT TO DO IN CASE OF FIRE  
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.  
• Don’t panic; stay calm. Follow your family escape plan.  
TROUBLESHOOTING GUIDE  
• 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.  
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.)  
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.
