About Smoke Alarms

Smoke alarms are essential safety devices that detect the presence of smoke in order to provide early warning of a fire. There are different types of smoke alarms available, each with its own features and functionality:

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 Battery march 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.
These smoke alarms are powered by batteries and 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 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 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. 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.

AC Powered Smoke Alarms
AC powered smoke alarms are connected to the electrical system of your home. They can be interconnected, meaning if one unit detects smoke, all units will alarm. However, they do not operate during power outages.

AC with Battery (DC) Backup Smoke Alarms
These smoke alarms have both AC power and battery backup. They will continue to operate during power outages, as long as 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 smoke 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 outages, as long as the batteries are fresh and correctly installed.

Smoke Alarms for Specific Uses
There are smoke alarms designed for specific uses:

• Smoke Alarms for solar or wind energy users and battery backup power systems: These AC powered smoke alarms should only be used with true or pure sine wave inverters. Using them with other types of inverters may cause damage to the alarm. Consult with the manufacturer of your inverter or UPS (uninterruptible power supply) for compatibility.
• Smoke Alarms for the hearing impaired: Special purpose smoke alarms with visual and audible alarms should be installed for the hearing impaired. These alarms meet the requirements of the Americans With Disabilities Act and can be interconnected.

Ionization Technology vs. Photoelectric Technology
Smoke alarms use different technologies to detect smoke:

• Ionization technology: This technology is more sensitive to small particles produced by flaming fires that consume combustible materials rapidly. It is suitable for detecting fires such as paper burning in a wastebasket or a grease fire in the kitchen.
• Photoelectric technology: This technology is more sensitive to large particles produced by smoldering fires that may take hours before bursting into flames. It is suitable for detecting fires such as cigarettes burning in couches or bedding.

For maximum protection, it is recommended to use both ionization and photoelectric smoke alarms on each level and in every bedroom of your home.

Product Usage Instructions

Installation

1. Before installing the smoke alarm, ensure that the power to the area where the alarm will be installed is turned off. This is important to prevent electrical shock.
2. Mount the smoke alarm on the provided mounting bracket, following the manufacturer’s instructions.
3. If the smoke alarm is AC powered, connect it to the electrical system of your home. If it has battery backup, ensure that the batteries are fresh and correctly installed.
4. If the smoke alarm is wireless interconnected, follow the manufacturer’s instructions to set up the wireless connection between multiple units.
5. Test the smoke alarm after installation to ensure proper functioning.

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).
NOTE: For added protection, install an additional Smoke 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 SMOKE ALARMS:

• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is more than 40 feet (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:

• 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 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 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 Alarm. To avoid dead air spaces, follow installation recommendations below. On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke 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 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 Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke 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 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. Tools you will need: needle- nose pliers or utility knife, standard flathead screwdriver, wire strippers.

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.

Maintenance
Regular maintenance is important to ensure the smoke alarm operates effectively:

• Test the smoke alarm monthly by pressing the test button. The alarm should sound loudly.
• Replace batteries in battery-operated smoke alarms at least once a year or as soon as the low battery warning chirps are heard.
• Clean the smoke alarm regularly to remove dust and debris that may hinder its performance. Use a vacuum cleaner or a soft brush to gently clean the openings.
• Replace the smoke alarm according to the manufacturer’s recommended lifespan, usually every 10 years.

FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations:

1. Use smoking materials properly. Never smoke in bed.
2. Keep matches or lighters away 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 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;
9. Have an escape plan and practice it regularly.

IF THIS SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM
During an Alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause. The Red LED flashes rapidly.

If the smoke alarm sounds:

1. Quickly identify the source of the smoke or fire.
2. If it is safe to do so, attempt to extinguish small fires using appropriate fire-fighting equipment.
3. Evacuate the premises immediately if the fire is spreading or cannot be controlled.
4. Call emergency services and provide them with accurate information about the situation.

WARNING!

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

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 Alarms” for details.

USING THE SILENCE FEATURES

The Silence Feature can temporarily quiet an unwanted Alarm for up to 8 minutes.

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.

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 on three times, repeating. The red LED will be Off on all other non-initiating Alarms. Once silenced, no audible sound will be heard. The unit will exit “silence mode” in approximately 8 minutes.

SILENCING THE LOW BATTERY WARNING
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 until you hear the acknowledge “chirp”. Once the low battery warning “chirp” Silence Feature is activated, the unit continues to flash the green light once a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace the batteries as soon as possible, to maintain protection in event of a power outage.

SILENCING THE END OF LIFE SIGNAL
This Silence Feature can temporarily quiet the End of Life warning “chirp” for up to 8 hours. You can silence the End of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life Silence Feature has been activated. Once the end of life battery warning “chirp” Silence Feature is activated, the unit continues to flash the green light 5 times a minute for 8 hours. After approximately 8 hours, the End of Life “chirp” will resume. The timer shall not be able to be reset after 7 days following the initial end-of-life signal.

IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of a dead or weak battery, a build-up of dirt, dust or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm as described in “Regular Maintenance,” and then test the Smoke Alarm again. If it fails to test properly when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.

• If you hear 3 or 5 chirps every minute or so, replace the Smoke Alarm.
• If you hear a chirp every minute, replace the battery.
• If you experience frequent non-emergency Alarms (like those caused by cooking smoke), try relocating the Smoke Alarm.
• If the Alarm sounds when no smoke is visible, try cleaning or relocating the Smoke Alarm. The cover may be dirty.
• If the Alarm does not sound during testing, make sure the power pack activating lever is pushed all the way securely.

Do not try fixing the Alarm yourself — this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty, please see “How to Obtain Warranty Service” in the Limited Warranty

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 level, 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.

• Smoke Alarms
• CO Alarms
• Both OR Combination Smoke/CO Alarms
• Wireless Alarms
• Wireless Interconnected Alarms
• _ Hardwired Interconnected AC or AC/DC Alarms

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

SPECIAL COMPLIANCE CONSIDERATIONS

This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day care facilities, health care facilities, boarding houses, group homes and dormitories provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations. This Smoke Alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums, hotels, motels, dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes of any kind. 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 Smoke Alarm may be used to provide additional protection in these facilities. In new construction, most building codes require the use of AC or AC/DC powered Smoke Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used as specified by local building codes. THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL FIRE PROTECTION ASSOCIATION’S STANDARD 72 (National Fire Protection Association, Battery march Park, Quincy, MA 02269). Refer to NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households”.

GENERAL LIMITATIONS OF SMOKE ALARMS

Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide. However, like any warning device, Smoke Alarms can only work if they are properly located, installed, and maintained, and if smoke reaches them. They are not foolproof. Smoke 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 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 Alarm while sleeping and to determine whether they may need assistance in the event of an emergency. Smoke 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. Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—especially if bedroom or sleeping area doors are closed at night—and in the hallway between them. Smoke Alarms may not detect fire on another level or area of the home. For example, a stand-alone unit on the second level may not detect smoke from a basement fire until the fire spreads. This may not give you enough time to escape safely. That is why recommended minimum protection is at least one unit in every sleeping area, and every bedroom on every level of your home. Even with a unit on every level, stand- alone units may not provide as much protection as interconnected units, especially if the fire starts in a remote area. Some safety experts recommend installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or professional fire detection systems, so if one unit senses smoke, all units Alarm. Interconnected units may provide earlier warning than stand-alone units since all units Alarm when one detects smoke. Smoke Alarms may not be heard. Though the Alarm horn in this unit meets or exceeds current standards, it may not be heard if: 1) the unit is located outside a closed or partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4) residents are hearing impaired or sound sleepers. Special purpose units, like those with visual and audible Alarms, should be installed for hearing impaired residents.

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. Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are made of components that can wear out or fail at any time. You must test the unit weekly to ensure your continued protection. Smoke Alarms cannot prevent or extinguish fires. They are not a substitute for property or life insurance. Smoke Alarms have a limited life. The unit should be replaced immediately if it is not operating properly. You should always replace a Smoke Alarm after 10 years from date of purchase. Write the purchase date on the space provided on back of unit.
