Introduction
This smoke and carbon monoxide alarm is suitable for marine or RV use. It is designed to detect smoke and carbon monoxide, providing essential safety in various environments.

About Smoke Alarms
Smoke alarms can be categorized into different types based on their power source and functionality

Battery (DC) Operated Smoke Alarms
These alarms provide protection even during power outages as long as the batteries are fresh and correctly installed. They are easy to install and do not require professional installation. However, they do not offer interconnected functionality.

AC Powered Smoke Alarms
These alarms can be interconnected, meaning that if one unit senses smoke, all units will sound the alarm. However, they rely on electricity and will not operate during power failures.

AC with Battery (DC) Backup Smoke Alarms
These alarms combine AC power with a battery backup. They will continue to operate even if electricity fails, provided that the batteries are fresh and correctly installed. It is recommended to have AC and AC/DC units installed by a qualified electrician.

Wireless Interconnected Alarms
These alarms offer the same interconnected functionality as hardwired alarms but without the need for wires. They are easy to install and do not require professional installation. They provide protection even during power failures, as long as the batteries are fresh and correctly installed.

Smoke Alarms for Special Applications
There are specific smoke alarms designed for different purposes

Solar or Wind Energy Users and Battery Backup Power
Systems: AC powered smoke alarms should only be used with true or pure sine wave inverters. Using them with most battery-powered UPS products or square wave/quasi sine wave inverters can damage the alarm. Consult with the manufacturer to verify compatibility.
Hearing Impaired: Special purpose smoke alarms equipped with visual alarms and audible alarm horns should be installed for the hearing impaired. These alarms meet the requirements of the Americans With Disabilities Act and can be interconnected.

Detector Guards
Smoke alarms should not be used with detector guards unless the combination has been specifically evaluated and found suitable for that purpose.

Ionization Technology vs. Photoelectric Technology

Ionization Technology: This technology is generally more sensitive to detecting small particles produced by flaming fires, which consume combustible materials rapidly and spread quickly. Examples of such fires include paper burning in a wastebasket or a grease fire in the kitchen.
Photoelectric Technology: This technology is generally more sensitive to detecting large particles produced by smoldering fires, which may smolder for hours before bursting into flame. Examples of such fires include cigarettes burning in couches or bedding.
Recommended Placement
For maximum protection, it is recommended to use both ionization and photoelectric smoke alarms on each level of your home and in every bedroom.

ABOUT SMOKE ALARMS

TYPES OF ALARMS
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 and Signaling 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.

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. They do not, however, provide interconnected functionality.
AC powered Smoke Alarms : Can be interconnected so if one unit senses smoke, all units Alarm. They do not operate if electricity fails.
AC with battery (DC) back-up : will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Wireless Interconnected Alarms: Offer the same interconnected functionality as with hardwired Alarms, without wires. Units are easy to install and do not require professional installation. They provide protection even
when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for solar or wind energy users and battery backup power systems: AC powered Smoke Alarms should only be operated with true or pure sine wave inverters. Operating this Smoke Alarm with most batterypowered UPS (uninterruptible power supply) products or square wave or “quasi sine wave” inverters will damage the Alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke Alarms should be installed for the hearing impaired. They include a visual Alarm and an audible Alarm horn, and meet the requirements of the Americans
With Disabilities Act. These units can be interconnected so if one unit senses smoke, all units Alarm.
Smoke Alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
All 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.

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.

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 (4.4˚ C and 37.8˚ C).

RECOMMENDED PLACEMENT

Smoke Alarm
One on every level and in every bedroom

Carbon Monoxide Alarm
One on every level and in every bedroom

Fire Extinguisher
One on every level, plus kitchen and garage

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.

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

WHERE NOT TO INSTALL THIS ALARM
FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE/CO ALARMS IN THESE AREAS

In garages, furnace rooms, crawl spaces and unfinished attics. 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, 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 areas where temperature is colder than 40˚ F (4.4˚ C) or hotter than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.
In insect infested areas. Insects can clog the openings to the sensing chamber.
Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
In “dead air” spaces.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke/CO Alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install Smoke/CO Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke/CO Alarm at least 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.
On a peaked, gabled, or cathedral ceiling, install the 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.

HOW TO INSTALL THIS ALARM

IMPORTANT!
This Smoke/CO Alarm is designed to be mounted on any standard wiring junction box up to a 4-inch (10 cm) size, on either the ceiling or wall (if allowed by local codes). Read “Where to Install This Alarm” and “Where This Alarm Should Not Be Installed” before you begin installation.
Find the self-adhesive labels included with this Smoke/CO Alarm.

On each label write in the phone number of your emergency responder (like 911) and a qualified appliance technician.
Place one label near the Smoke/CO Alarm, and the other label in the “fresh air” location you plan to go if the Alarm sounds.

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.”

Tools you will need: needle-nose pliers or utility knife, standard flathead screwdriver, wire strippers (for interconnected Alarms)

WARNING
Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your Alarm.

LATCHING FEATURES

Alarm Latch is activated after an Alarm is exposed to Alarm levels of smoke or carbon monoxide. This feature will only work with AC power. See “Special Requirements for Interconnected Alarms” for signaling.
This feature helps emergency responders, investigators, or service technicians identify which unit(s) in your home were exposed to Alarm levels of smoke. This can help investigators pinpoint the source of smoke.
Interconnected Alarms. Latching Alarm Indicator shows which Alarm(s) in the series were exposed to Alarm levels of smoke. The Latching Alarm Indicator stays ON until you clear it, so it can alert you to an Alarm that occurred while you were away from home, even though smoke present in the air has dropped below Alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this occurs, the Green LED flashes 2 seconds on, 2 seconds off. This feature is designed to help you identify which Alarm needs to be replaced.

$First-Alert-SMICO105-AC-Smoke-and-Carbon-Monoxide-Alarm $9$$ “SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected with other First Alert® Smoke, Heat, and “Smart Interconnect” CO Alarms. When smoke is detected, all Alarms will sound the smoke horn pattern. When CO is detected, “Smart Interconnect” Alarms will sound the CO horn pattern. Alarms that do not have the “Smart Interconnect” feature will remain silent during a CO Alarm.

OPTIONAL LOCKING FEATURE
The optional locking feature is designed to discourage unauthorized removal of the Alarm. It is not necessary to activate the locks in single-family households where unauthorized removal is not a concern.

Tools you will need : Needle-nose pliers or utility knife, standard flathead screwdriver

FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations

Use smoking materials properly. Never smoke in bed.
Keep matches or lighters away from children;
Store flammable materials in proper containers;
Keep electrical appliances in good condition and don’t overload electrical circuits;
Keep stoves, barbecue grills, fireplaces and chimneys grease- and debris-free;
Never leave anything cooking on the stove unattended;
Keep portable heaters and open flames, like candles, away from flammable materials;
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 level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked;
Have an escape plan and practice it regularly.

IF YOUR SMOKE/CO ALARM SOUNDS

WHAT TO DO FIRST: IDENTIFY THE TYPE OF ALARM SIGNAL
Refer to previous section “What You Will See And Hear With This Alarm”.

WARNING
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

Press the Test/Silence button.
Call your emergency services, fire department or 911. Write down the number of your local emergency service here
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.
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 investigate 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.”

IF THE SMOKE/CO ALARM SOUNDS
RESPONDING TO AN ALARM

WARNING
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.
If the unit Alarms get everyone out of the house immediately.

DANGER
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.

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.
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.

WARNING
Alarms have various limitations. See “General Limitations of Smoke/CO Alarms” for details.

USING THE SILENCE FEATURES

WARNING
The Silence Feature does not disable the unit—it makes it temporarily less sensitive to smoke. For your safety, if smoke around the unit is dense enough to suggest a potentially dangerous situation, the unit will stay in Alarm or may re-Alarm quickly. If you do not know the source of the smoke, do not assume it is an unwanted Alarm. Not responding to an Alarm can result in property loss, injury, or death. If the unit will not silence and no heavy smoke is present, or if it stays in silence mode continuously, it should be replaced immediately.
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.
The Silence Feature can temporarily quiet an unwanted Alarm for several minutes. You can silence this Smoke/CO Alarm by pressing the Test/Silence button on the Alarm cover.

Activate the Alarm test, reset or silence function by use of a finger or thumb. Use of any other instrument is strictly prohibited.

When the Smoke Alarm is Silenced
The Smoke Alarm will remain silent for up to 15 minutes, then returns to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into Alarm.
When the CO Alarm is Silenced
The CO Alarm will remain silent for up to 6 minutes.
After 6 minutes, if CO levels remain potentially dangerous the horn will start sounding again.

TO SILENCE SMOKE ALARMS IN AN INTERCONNECTED SERIES

To silence multiple Alarms in an interconnected series, you must press the Test/Silence button on the unit(s) that initiated the Alarm. NOTE: The red LED on the initiating Alarm will flash. The red LED will be Off on all other non-initiating Alarms. Once silenced, no audible sound will be heard.
While the unit is in “silence mode”, pressing and holding the Test/Silence button for approximately 10 seconds will test the unit. After testing, the unit will re-enter “silence mode” and the timer is reset.

SILENCING THE LOW BATTERY/END OF LIFE WARNING
This Silence Feature can temporarily quiet the low battery/end of life warning “chirp” for up to 48 hours. Press the Test/Silence button on the Alarm cover until you hear the acknowledge “chirp”.
Once the low battery/end of life warning “chirp” Silence Feature is activated, the unit continues to flash the green light 5 times every minute for up to 48 hours. Then, the end of life “chirp” will resume. Replace the unit as soon as possible, to maintain protection in event of a power outage.

WHAT YOU NEED TO KNOW ABOUT CO

WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are exposed to heat (usually fire). Electrical appliances typically do not produce CO.

These fuels include : Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger now that homes are more energy efficient. “Air- tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside.

SYMPTOMS OF CO POISONING

These symptoms are related to CO POISONING and should be discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to carbon monoxide can cause brain damage, death.

IMPORTANT!
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!

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. First Alert shall not be obligated to pay for any carbon monoxide investigation or service call.

POTENTIAL SOURCES OF CO IN THE HOME

Fuel-burning appliances like
portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.

Damaged or insufficient venting
corroded or disconnected water heater vent pipe, leaking chimney pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.

Improper use of appliance/ device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.

The following conditions can result in transient CO situations

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.
Extended operation of unvented fuel burning devices (range, oven, fireplace).
Temperature inversions, which can trap exhaust close to the ground.
Car idling in an open or closed attached garage, or near a home.

These conditions are dangerous because they can trap exhaust in your home. Since these conditions can come and go, they are also hard to recreate during a CO investigation.

HOW CAN I PROTECT MY FAMILY FROM CO POISONING

A CO Alarm is an excellent means of protection. It monitors the air and sounds a loud Alarm before carbon monoxide levels become threatening for average, healthy adults. A CO Alarm is not a substitute for proper maintenance of home appliances.

TO HELP PREVENT CO PROBLEMS AND REDUCE THE RISK OF CO POISONING

Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks, or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances. Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches.
Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
Check the house or garage on the other side of shared wall.
Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window or a door. Opening windows and doors can significantly decrease CO levels.

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

REGULATORY INFORMATION FOR SMOKE ALARMS

RECOMMENDED LOCATIONS FOR SMOKE ALARMS
INSTALLING SMOKE ALARMS IN SINGLE-FAMILY RESIDENCES
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F (37.8˚ 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 doors closed.
In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each.
If a hall is over 40 feet (12 meters) long, install an Alarm at each end.
At the top of the first-to-second level stairway, and at bottom of basement stairway.

IMPORTANT
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.

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).
The unit is designed not to Alarm when exposed to a constant level of 30 ppm for 30 days.

IMPORTANT!
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).

AGENCY PLACEMENT RECOMMENDATIONS

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

GENERAL LIMITATIONS OF SMOKE/CO ALARMS

This Smoke/CO Alarm is intended for residential use. This product is intended for use in ordinary indoor locations of family living units. 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. For additional information on carbon monoxide and your medical condition contact your physician.
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 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.
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, when a person’s clothing catches fire while cooking, fires caused by violent explosions resulting from escaping gas, or incendiary fires where the fire grows so rapidly that an occupant’s egress is blocked even with properly located Smoke Alarms.
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, First Alert 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.
