INTRODUCTION

Thank you for choosing First Alert® for your Smoke Alarm needs. You have purchased a state of the art Smoke Alarm designed to provide you with early warning of
a fire. Please take the time to read this manual and make the Smoke Alarm an integral part of your family’s safety plan.

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.

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 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.

BEFORE YOU INSTALL THIS SMOKE ALARM

IMPORTANT! Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke Alarms” before beginning. This unit monitors the air, and when
smoke reaches its sensing chamber, it alarms. It can give you more time to escape before fire spreads. This unit can ONLY give an early warning of developing fires
if it is installed, maintained and located where smoke can reach it, and where all residents can hear it, as described in this manual. This unit will not sense gas,
heat, or flame. It cannot prevent or extinguish fires.
Understand The Different Type of Smoke Alarms: Battery powered or electrical? Different Smoke Alarms provide different types of protection. See “About Smoke
Alarms” for details.
Know Where To Install Your Smoke Alarms: Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in every bedroom, and in
every bedroom hallway or separate sleeping area. See “Recommended Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
Know What Smoke Alarms Can and Can’t Do: A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound an alarm once
smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
Check Your Local Building Codes: This Smoke Alarm is designed to be used in a typical single-family home. It alone will not meet requirements for boarding
houses, apartment buildings, hotels or motels. See “Special Compliance Considerations” for details.

WEEKLY TESTING

• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to your home. The built-in test switch
accurately tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).

• If the Alarm ever fails to test properly, replace it immediately. Products under warranty may be returned to the manufacturer for replacement. See
“Limited Warranty” for details.

• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be harmful to your hearing. When testing, step away when
horn starts sounding.

It is important to test this unit every week to make sure it is working properly. Using the test/silence button is the recommended way to test this Smoke

Alarm. Press and hold the test/silence button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a few seconds after you release the
button). If it does not alarm, make sure the unit is receiving power (LED will flash approximately once a minute indicating it has power); and test it again. If it still
does not alarm, replace it immediately. During testing you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
___________________________________________________________________________________________________________________________

REGULAR MAINTENANCE

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.

• Test it at least once a week.

• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.

• If the Smoke Alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot be cleaned to avoid unwanted alarms, replace the unit immediately.

• Relocate the unit if it sounds frequent unwanted alarms. See “Locations to Avoid For Smoke Alarms” for details.

• When the battery becomes weak, the Smoke Alarm unit will “chirp” approximately once a minute (the low battery warning). This low battery warning should last
for up to 7 days, but you should replace the battery immediately to continue your protection.

CHOOSING A REPLACEMENT BATTERY: Your Smoke Alarm requires one standard 9V battery. The following batteries are acceptable as replacements: Eveready
1222, Duracell MN1604, (Ultra) MX1604; Energizer 522. You may also use a Lithium battery like the Duracell DL1604 for longer service life between battery
changes. These batteries are available at many local retail stores.

• Always use the exact batteries specified by this User’s Manual. DO NOT use rechargeable batteries. Clean the battery contacts and also those of the
device prior to battery installation. Install batteries correctly with regard to polarity (+ and -).

• Please dispose of or recycle used batteries properly, following any local regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.

• Keep battery out of reach of children. In the event a battery is swallowed, immediately contact your poison control center, your physician, or the
National Battery Ingestion hotline at 202-625-3333 as serious injury may occur.

Actual service life depends on the Smoke Alarm and the environment in which it is installed. All the batteries specified above are acceptable replacement batteries for
this unit. Regardless of the manufacturer’s suggested battery life, you MUST replace the battery immediately once the unit starts “chirping” (the “low battery warning”).

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 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.

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

corner). Trace around the insides of the mounting
slots.

4. Put the unit where it won’t get covered with dust
when you drill the mounting holes.

5. Using a 3/16” (5 mm) drill bit, drill a hole through
the center of the oval outlines you traced in step
#3.

6. 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.
