Consumer Affairs: (800)
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.
WIRELESS OPERATION
First Alert® ONELINK® Technology is the easy,
The communication distance (range) between any two ONELINK® Alarms is typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number of floors, number/size of rooms, furniture and types of building materials used may reduce the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic appli- ances (refrigerators) and metal studs. A feature of ONELINK® Alarms is that they operate as a mesh network. All Alarms will repeat any alarm signal that is received to all other ONELINK® Alarms. Interference from structural conditions can be overcome by adding additional Alarms to route the wireless signal around obstructions.
•The range and proper operation of any wireless device will vary depending on its surroundings. It is very important that each Alarm is tested individually before and after installation to make sure that all Alarms respond properly.
•The ONELINK® Alarms are not to be used outdoors or to transmit between buildings. The Alarms will not communicate properly under these conditions.
•Metal objects and metallic wallpaper may interfere with signals from wireless Alarms. Alarms should be tested after changes to your home such as remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert® ONELINK® Smoke/CO Alarm will automatically commu- nicate both potential fires and carbon monoxide presence with all other First Alert® ONELINK® Smoke/CO Alarms.
FCC NOTICE: This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC ID: M7U5001L

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. |

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:
•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.
•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.
•At the top of
•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).

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 before beginning any installation.
In new construction AC and AC/DC smoke alarms MUST be interconnected to meet NFPA recommendations.
Recommended Placement
•When installing on the wall, the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
•When installing on the ceiling, place the Alarm as close to the center as possible.
•In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the Alarm.
Installing Smoke/CO Alarms in Mobile Homes
For minimum security install one Smoke/CO 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.

IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO
Refer to previous section “What You Will See and Hear With This Alarm”.
IF THE CO ALARM SOUNDS
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
Actuation of your CO Alarm indicates the presence of carbon monoxide (CO) which can kill you. In other words, when your CO Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1.Operate the Test/Silence button.
2.Call your emergency services, fire department or 911. Write down the number of your local emergency service here:

RESPONDING TO AN ALARM
•If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
•Never remove the batteries from a battery operated Smoke/CO Alarm 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 auto- matically.
•If the unit alarms get everyone out of the house immediately.
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.
Alarms have various limitations. See "General Limitations of Smoke/CO Alarms" for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing the batteries disables the alarm and removes your protection.
The 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 for at least
