All First Alert® and BRK® Smoke Alarms conform to regulatory requirements, including UL217, and are designed to detect particles of combustion. Ionization technology is generally more sensitive to small particles produced by flaming fires, while photoelectric technology is more sensitive to large particles from smoldering fires. For maximum protection, use both types of Smoke Alarms.
Fire Safety Tips
- 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 do not overload circuits.
- Keep stoves, barbecue grills, fireplaces, and chimneys clean and debris-free.
- Never leave cooking unattended.
- Keep portable heaters and open flames away from flammable materials.
- Do not let rubbish accumulate. Keep alarms clean and test them weekly. Replace alarms immediately if not working properly.
- 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 if stairs are blocked.
Before You Install This Smoke Alarm
Read "Recommended Locations for Smoke Alarms" and "Locations to Avoid for Smoke Alarms" before installation. This unit monitors air and alarms when smoke reaches its sensing chamber, providing early warning. It can only provide this warning if installed, maintained, and located where smoke can reach it and all residents can hear it. It does not sense gas, heat, or flame, nor can it prevent or extinguish fires.
Understand The Different Types of Smoke Alarms: Battery powered or electrical? Different alarms provide different protection.
Know Where To Install Your Smoke Alarms: Fire safety professionals recommend at least one alarm on every level, in every bedroom, and in every bedroom hallway. See location details below.
Know What Smoke Alarms Can and Can't Do: Alarms alert you to fire by sounding when smoke reaches the sensor. See "Limitations of Smoke Alarms" for details.
Check Your Local Building Codes: This alarm is for typical single-family homes. It alone will not meet requirements for boarding houses, apartment buildings, hotels, or motels. See "Special Compliance Considerations" for details.
ELECTRICAL SHOCK HAZARD: Turn off power to the area where the Smoke Alarm is installed before removing it from the mounting bracket. Failure to do so may result in serious electrical shock, injury, or death.
- This unit will not alert hearing-impaired residents. Special units with strobe lights are recommended for them.
- Installation must conform to local electrical codes and NFPA 70 (NEC), NFPA 72, NFPA 101, ICC, SBC, UBC, NBC, OTFDC, and other applicable codes. Wiring and installation must be performed by a licensed electrician.
- This unit must be powered by a 24-hour, 120V AC pure sine wave 60 Hz circuit. Ensure the circuit cannot be turned off by a switch, dimmer, or GFCI.
- This Smoke Alarm requires AC or battery power to operate. Battery backup provides at least 4 minutes of alarm if AC fails. If AC fails and battery is weak, protection lasts up to 7 days. If AC fails and battery is dead or missing, the alarm cannot operate.
- Never disconnect power to stop an unwanted alarm; this disables the unit. Open a window or fan smoke away. The alarm will reset automatically. Never remove batteries from a battery-operated unit to stop an unwanted alarm; open a window or fan smoke away.
- Connect this unit ONLY to other compatible units. Do not connect to other alarm types or auxiliary devices.

Weekly Testing
NEVER use an open flame to test this unit. Use the built-in test switch. Do not stand close to the Alarm when the horn is sounding.
Test the unit weekly by pressing and holding the test button until the alarm sounds. If it does not alarm, check power and test again. If it still fails, replace immediately. For interconnected units, test each unit individually.
Regular Maintenance
- Test at least once a week.
- Clean the Smoke Alarm at least once a month using a soft brush attachment on your vacuum cleaner. Test after cleaning. Never use water, cleaners, or solvents.
- If the unit becomes contaminated and cannot be cleaned to avoid unwanted alarms, replace it immediately.
- Relocate the unit if it sounds frequent unwanted alarms.
- Replace the battery immediately when the unit "chirps" (low battery warning).
Choosing a replacement battery: Use one standard 9V battery (e.g., Duracell #MN1604, Eveready #522). Lithium batteries (e.g., Ultralife U9VL-J) offer longer life. Do not use rechargeable batteries. Clean battery contacts before installation. Install with correct polarity.
Dispose of or recycle used batteries properly. Do not dispose of batteries in fire. Keep batteries out of reach of children.
If This Smoke Alarm Sounds
NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
- If the unit alarms and you are not testing it, respond immediately.
- Never disconnect AC power to quiet an unwanted alarm; this disables the unit. Open a window or fan smoke away. The alarm will reset automatically.
- Get everyone out of the house immediately.
- If the source of smoke is not a fire (e.g., cooking smoke), open a window or fan smoke away. Use the Silence Feature to silence the alarm temporarily.
What to Do in Case of Fire
- Stay calm. Follow your family escape plan.
- Get out quickly. Don't stop to dress or collect belongings.
- Feel doors with the back of your hand before opening. If cool, open slowly. Don't open hot doors. 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. Do a head count.
- Call the Fire Department from outside immediately.
- Never go back inside a burning building.
- Contact your Fire Department for ideas on making your home safer.
Using the Silence Feature
The Silence Feature temporarily quiets an unwanted alarm for up to 10 minutes. It makes the unit less sensitive but does not disable it. If smoke is dense, the unit may stay in alarm or re-alarm. If you don't know the source, do not assume it's unwanted. If the unit will not silence or stays in silence mode, replace it.
To silence alarms in an interconnected series, press the Test/Silence button on the unit(s) that initiated the alarm. The initiating alarm's red LED will flash rapidly; others will be off. The unit will exit silence mode in approximately 10 minutes. Pressing the button again during silence mode tests the unit and resets the 10-minute timer.
"Latching Alarm" Indicator
This indicator is automatically activated after an alarm is exposed to alarm levels of smoke. After smoke levels drop, the green LED will flash (2 seconds on/2 seconds off). This helps identify which unit(s) were exposed to smoke. The indicator stays on until reset by pressing the Test/Silence button or by removing AC and DC power.
If You Suspect a Problem
Problems may be due to dead/weak batteries, dirt/dust/grease buildup, or improper location. Clean the alarm, install a fresh battery, and test again. If it fails to test properly or the problem persists, replace the alarm immediately.
- If you hear a "chirp" once a minute, replace the battery.
- For frequent non-emergency alarms (e.g., cooking smoke), try relocating the alarm.
- If the alarm sounds with no visible smoke, try cleaning or relocating it.
- If the alarm does not sound during testing, ensure it is receiving AC power.
ELECTRICAL SHOCK HAZARD: Always discharge the branch circuit before servicing. Turn off AC power, remove battery, then press and hold test button for 5-10 seconds.
Do not try to fix the alarm yourself; this will void your warranty!
Recommended Locations for Smoke Alarms
Single-Family Residences: NFPA recommends one alarm on every floor, in every sleeping area, and in every bedroom. New construction requires AC powered and interconnected alarms. For additional coverage, install alarms in all rooms, halls, storage areas, finished attics, and basements (40°F to 100°F / 4.4°C to 37.8°C). Ensure no obstructions block smoke.
- On every level of your home, including finished attics and basements.
- Inside every bedroom.
- In the hall near every sleeping area. If a hall is over 40 feet (12 meters) long, install a unit at each end.
- At the top of the first-to-second floor stairway, and at the bottom of the basement stairway.
Specific requirements vary by location; check with your local Fire Department. Interconnected AC or AC/DC units are recommended for added protection.
Agency Placement Recommendations (NFPA 72)
29.5.1* Required Detection:
- (1)* In all sleeping rooms and guest rooms.
- (2)* Outside of each separate dwelling unit sleeping area, within 21 ft (6.4 m) of any door to a sleeping room, measured along the path of travel.
- On every level of a dwelling unit, including basements.
- On every level of a residential board and care occupancy (small facility), including basements (excluding crawl spaces and unfinished attics).
- In the living area(s) of a guest suite.
- In the living area(s) of a residential board and care occupancy (small facility).
(Reprinted with permission from NFPA 72®, National Fire Alarm and Signaling Code. Copyright © 2010 National Fire Protection Association.)
California State Fire Marshal (CSFM) Recommendations: Install detection equipment in all rooms and areas: in each separate sleeping area (outside bedrooms), and Heat or Smoke Alarms in living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility/storage rooms, basements, and attached garages.
Locations to Avoid for Smoke Alarms
For best performance, AVOID installing Smoke Alarms in these areas:
- Where combustion particles are produced: Poorly ventilated kitchens, garages, furnace rooms. Keep units at least 20 feet (6 meters) from sources like stoves, furnaces, water heaters, space heaters. In smaller homes, place as far as possible from these sources. Ventilate these areas well.
- In air streams near kitchens: Air currents can draw cooking smoke into the sensing chamber.
- In very damp, humid, or steamy areas: Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
- Where temperatures are regularly below 40°F (4.4°C) or above 100°F (37.8°C): Including unheated buildings, outdoor rooms, porches, or unfinished attics/basements.
- In very dusty, dirty, or greasy areas: Do not install directly over a stove or range. Clean laundry room units frequently.
- Near fresh air vents, ceiling fans, or in very drafty areas: Drafts can blow smoke away from the unit.
- In insect-infested areas: Insects can clog 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: These may prevent smoke from reaching the alarm.
Avoiding Dead Air Spaces
On ceilings, install alarms near the center or at least 4 inches (102 mm) from the wall/corner. For wall mounting, the top edge should be 4 to 12 inches (102 to 305 mm) from the wall/ceiling line. On peaked ceilings, install within 3 feet (0.9 meters) of the peak.
About Smoke Alarms
- Battery (DC) operated: Provide protection during power failure if batteries are fresh and installed. Easy to install, but lack interconnected functionality.
- AC powered: Can be interconnected. Do not operate if electricity fails.
- AC with battery (DC) back-up: Operates during power failure if batteries are fresh. Must be installed by a qualified electrician.
- Wireless Interconnected: Offer interconnected functionality without wires. Easy to install, battery-powered.
- For Solar or Wind Energy users: Use only with true or pure sine wave inverters. Avoid square wave or "quasi sine wave" inverters.
- For the hearing impaired: Special units with visual and audible alarms are available and can be interconnected.
Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable. All alarms are designed for early warning if located, installed, and cared for properly, and if smoke reaches them. Consult NFPA 72 and NFPA 101, and local building codes for specific requirements.
Special Compliance Considerations
This Smoke Alarm is suitable for apartments, condominiums, townhouses, hospitals, day care, health care facilities, boarding houses, group homes, and dormitories IF a primary fire detection system already exists for common areas. It is NOT a substitute for complete fire detection systems in places housing many people (apartment buildings, hotels, etc.) or in warehouses, industrial, or commercial buildings. Check local codes for use in new construction (often requires AC/DC only) or existing construction.
Limitations of Smoke Alarms
Smoke Alarms are not foolproof. They require proper location, installation, and maintenance. They may not wake all individuals, especially those with mobility limitations or who are deep sleepers. They require power (AC or battery); failure of either means no protection. They cannot detect fires if smoke does not reach the sensors (e.g., fires in walls, chimneys, or on the other side of closed doors). They may not be heard over loud noises or by the hearing impaired. They cannot prevent or extinguish fires. They have a limited life (replace after 10 years from purchase date).

What You Need to Know About CO
What is CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels (wood, coal, oil, natural gas, gasoline, propane) do not burn completely or are exposed to heat. Electrical appliances typically do not produce CO. Malfunctioning or improperly ventilated fuel-burning appliances can cause CO levels to rise quickly. Energy-efficient homes can trap CO inside.
Symptoms of CO Poisoning
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 and death. Consult your doctor immediately if you experience even mild symptoms.
Finding the Source of CO After an Alarm
CO is odorless and invisible, making it hard to locate. Factors like ventilation before investigator arrival, "backdrafting," or transient CO problems can make detection difficult. BRK Brands, Inc. is not obligated to pay for CO investigations or service calls.
Potential Sources of CO in the Home
- Fuel-burning appliances: portable heaters, gas/wood fireplaces, gas ranges/cooktops, gas clothes dryers.
- Damaged or insufficient venting: corroded/disconnected vent pipes, leaking chimneys, cracked heat exchangers, blocked chimney openings.
- Improper use of appliances: operating grills or vehicles in enclosed areas (garages, screened porches).
- Transient CO Problems: Caused by outdoor conditions (wind, cold/humid air, negative pressure from exhaust fans, competing appliances) or extended operation of unvented devices.
How Can I Protect My Family From CO Poisoning?
A CO Alarm is an excellent means of protection. However, it is not a substitute for proper appliance maintenance.
- Clean chimneys and flues yearly. Keep them free of debris. Have professionals check for rust, corrosion, cracks, or separations. Never cap or cover a chimney in a way that blocks airflow.
- Test and maintain all fuel-burning equipment annually.
- Perform regular visual inspections of fuel-burning appliances. Check for excessive rust/scaling. Burner flames and pilot lights should be blue; yellow flames indicate incomplete combustion and potential CO. Keep furnace blower doors closed. Use vents or fans when available. Ensure appliances are vented to the outside. Do not grill indoors or in garages.
- Check for exhaust backflow from CO sources. Check furnace draft hoods and heat exchangers for cracks.
- Check the house or garage on the other side of a shared wall.
- Keep windows and doors open slightly if you suspect CO escaping into your home.
Familiarize yourself with all enclosed materials and understand what to do if your CO Alarm sounds.
Regulatory Information for CO Alarms
What Levels of CO Cause an Alarm?
UL2034 requires residential CO Alarms to sound at specific CO levels and exposure times:
- 400 ppm: Alarm between 4 and 15 minutes.
- 150 ppm: Alarm between 10 and 50 minutes.

General Limitations of CO Alarms
This CO Alarm is for residential use only, not industrial applications. It is not intended for hearing-impaired residents. CO Alarms may not awaken all individuals; assign assistance for those with mobility limitations or who are deep sleepers. The alarm will only sense CO that reaches the sensors; doors or obstructions can affect CO reaching the sensors. CO Alarms may not be heard over loud noises or by the hearing impaired. This CO Alarm is not a substitute for life insurance. It is not foolproof; components can fail, requiring weekly testing. It cannot prevent or extinguish fires.
