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.

KEY FEATURES OF THE P1210 SMOKE ALARM:
Photoelectric Sensing Technology: 

Photoelectric Sensors are generally more sensitive than ionization sensors in detecting smoldering fires which commonly occur 

in couches or bedding.

OptiPath 360 Technology™: 

Patented technology provides 360° of direct access to the smoke sensor.

Single Test/Silence Button:

 Allows you to test the Alarm or silence nuisance alarms. Testing the Alarm assures you that the unit is functioning correctly and ready 

to protect you and your family. The Alarm can be silenced for up to 9 minutes in the event of a nuisance alarm.

10 Year End of Life Indicator:

 3 horn pulses every 43 seconds alerts you that the unit must be replaced.

Local Alarm Memory: Green LED flashes 3 times every 43 seconds for 24 hours. After 24 hours the unit will chirp rapidly while the Test button is pressed. Memory is 
cleared when the button is released.

Low battery warning: 

The Alarm will sound a “chirp” once per minute when the Smoke Alarm needs to be replaced.

Low battery silence: 

The Alarm can be silenced for 8 hours.

Red Blinking Power Indicator every 6 minutes:

 Confirms that the Smoke Alarm is receiving power

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.

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. 
• 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 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. Red LED flashes rapidly.

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 30 days, but you should replace the Smoke Alarm immediately to continue your protection.

 

Actual service life depends on the Smoke Alarm and the environment in which it is installed. You MUST replace the Smoke Alarm 

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 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.

 Alarms have various limitations. See “Limitations of Smoke Alarms” for details.

USING THE SILENCE FEATURE

The Silence Feature can temporarily quiet an unwanted alarm for up to 9 minutes. To use this feature, press the Test/Silence button on the cover. 

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

. The LED will flash every 10 seconds 

while in silence.

 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.

SILENCING THE LOW BATTERY WARNING

This silence feature can temporarily quiet the Low Battery warning “chirp”. Press the Test/Silence button on the Alarm. The Red light flashes normally, once every 6 
minutes, during Low Battery Warning Silence. After time, the low battery “chirp” will resume.

 Deactivate the Smoke Alarm and replace it immediately.

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 a “chirp” about once a minute, replace the Smoke Alarm.
• 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.

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 floor stairway, and at bottom of basement stairway.

 

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.

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.

HOW TO INSTALL THIS SMOKE ALARM

OPTIONAL LOCKING FEATURE

The optional locking feature is designed to prevent unauthorized removal of the alarm. It is not necessary to 
activate the lock in single-family households where unauthorized alarm removal is not a concern.  

Tools you will need:

  Needle-nose pliers or utility knife • Standard flathead screwdriver

The feature uses a locking pin which is molded into the mounting bracket.  Remove locking pin by using 
needle-nose pliers or a utility knife.

 To permanently remove the locking pin, insert a flathead screwdriver 

between the locking pin and the lock and pry the pin out of the lock.

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.
___________________________________________________________________________________________________________________________

LOCATIONS TO AVOID FOR SMOKE ALARMS

FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE ALARMS IN THESE 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.

• In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the 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 or 

basements.

• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. Keep laundry room Smoke Alarms free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit, preventing it from reaching the sensing chamber.
• In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air spaces, follow the 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 and 12 inches (102 and 305 mm) from the wall/

ceiling line, below typical “dead air” spaces.

ON A PEAKED, GABLED, OR CATHEDRAL CEILING,

 install the 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.

FOLLOW THESE SIMPLE STEPS

1. Hold the mounting bracket against the 

ceiling (or wall) so the two clusters of 
universal mounting holes are aligned 
approximately at the 9:00 and 3:00 
o’clock positions. See image. Choose 
one of the three sets of holes shown, A, 
B or C (see image) and trace around one 
of the sets. Be sure to choose a top and 
bottom slot on opposite sides so you can 
rotate the universal mounting bracket into 
position later. This will make it easier in 
the future to remove the mounting bracket 
without completely removing the screws.

WARNING! Do not install this Smoke Alarm over an existing electrical box. 
Only AC powered units are intended for installation over electrical boxes.

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

holes.

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

you traced.

4. 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.

5. Install the screws but do not tighten completely. Attach the mounting bracket 

by aligning the screws in the open portion of the universal mounting slots and 
rotating the bracket into place. Tighten the screws until they are snug to secure 
the bracket. Do not over tighten.

6. 

Activating the battery. 

Mount alarm to mounting bracket to activate. Once unit 

is activated, it cannot be turned off.

NOTE: After you activate the battery, the power indicator light may flash. 
(If the unit alarms, the light will blink rapidly, and the horn will repeatedly 
sound 3 beeps, pause, 3 beeps.) Once the Smoke Alarm is on the bracket, 
you can rotate the Alarm to adjust the alignment.

7. Test the Smoke Alarm. See “Weekly Testing.”
8. After 10 years of operation or Low Battery 

warning, deactivate the Smoke Alarm: Insert a tool 
below edge where shown and break tab. Then 
slide activation switch to deactivate mode.

NOTE: At end of life or low battery indication (chirp): unit must be put into 
deactivation mode to deactivate remaining stored energy in battery. Unit will 
no longer function once put into this mode. Unit will resist re-mounting.

Low battery warning: 

The Alarm will sound a “chirp” once per minute when the Smoke Alarm needs to be replaced.

Low battery silence: 

The Alarm can be silenced for 8 hours.

Red Blinking Power Indicator every 6 minutes:

 Confirms that the Smoke Alarm is receiving power

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.

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.

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. 
• 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 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. Red LED flashes rapidly.

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 30 days, but you should replace the Smoke Alarm immediately to continue your protection.

 

Actual service life depends on the Smoke Alarm and the environment in which it is installed. You MUST replace the Smoke Alarm 

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 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.

 Alarms have various limitations. See “Limitations of Smoke Alarms” for details.

USING THE SILENCE FEATURE

The Silence Feature can temporarily quiet an unwanted alarm for up to 9 minutes. To use this feature, press the Test/Silence button on the cover. 

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

. The LED will flash every 10 seconds 

while in silence.

 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.

SILENCING THE LOW BATTERY WARNING

This silence feature can temporarily quiet the Low Battery warning “chirp”. Press the Test/Silence button on the Alarm. The Red light flashes normally, once every 6 
minutes, during Low Battery Warning Silence. After time, the low battery “chirp” will resume.

 Deactivate the Smoke Alarm and replace it immediately.

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 a “chirp” about once a minute, replace the Smoke Alarm.
• 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.

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 floor stairway, and at bottom of basement stairway.

 

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.

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.

HOW TO INSTALL THIS SMOKE ALARM

OPTIONAL LOCKING FEATURE

The optional locking feature is designed to prevent unauthorized removal of the alarm. It is not necessary to 
activate the lock in single-family households where unauthorized alarm removal is not a concern.  

Tools you will need:

  Needle-nose pliers or utility knife • Standard flathead screwdriver

The feature uses a locking pin which is molded into the mounting bracket.  Remove locking pin by using 
needle-nose pliers or a utility knife.

 To permanently remove the locking pin, insert a flathead screwdriver 

between the locking pin and the lock and pry the pin out of the lock.

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.
___________________________________________________________________________________________________________________________

LOCATIONS TO AVOID FOR SMOKE ALARMS

FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE ALARMS IN THESE 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.

• In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the 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 or 

basements.

• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. Keep laundry room Smoke Alarms free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit, preventing it from reaching the sensing chamber.
• In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air spaces, follow the 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 and 12 inches (102 and 305 mm) from the wall/

ceiling line, below typical “dead air” spaces.

ON A PEAKED, GABLED, OR CATHEDRAL CEILING,

 install the 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.

FOLLOW THESE SIMPLE STEPS

1. Hold the mounting bracket against the 

ceiling (or wall) so the two clusters of 
universal mounting holes are aligned 
approximately at the 9:00 and 3:00 
o’clock positions. See image. Choose 
one of the three sets of holes shown, A, 
B or C (see image) and trace around one 
of the sets. Be sure to choose a top and 
bottom slot on opposite sides so you can 
rotate the universal mounting bracket into 
position later. This will make it easier in 
the future to remove the mounting bracket 
without completely removing the screws.

WARNING! Do not install this Smoke Alarm over an existing electrical box. 
Only AC powered units are intended for installation over electrical boxes.

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

holes.

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

you traced.

4. 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.

5. Install the screws but do not tighten completely. Attach the mounting bracket 

by aligning the screws in the open portion of the universal mounting slots and 
rotating the bracket into place. Tighten the screws until they are snug to secure 
the bracket. Do not over tighten.

6. 

Activating the battery. 

Mount alarm to mounting bracket to activate. Once unit 

is activated, it cannot be turned off.

NOTE: After you activate the battery, the power indicator light may flash. 
(If the unit alarms, the light will blink rapidly, and the horn will repeatedly 
sound 3 beeps, pause, 3 beeps.) Once the Smoke Alarm is on the bracket, 
you can rotate the Alarm to adjust the alignment.

7. Test the Smoke Alarm. See “Weekly Testing.”
8. After 10 years of operation or Low Battery 

warning, deactivate the Smoke Alarm: Insert a tool 
below edge where shown and break tab. Then 
slide activation switch to deactivate mode.

NOTE: At end of life or low battery indication (chirp): unit must be put into 
deactivation mode to deactivate remaining stored energy in battery. Unit will 
no longer function once put into this mode. Unit will resist re-mounting.

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.

KEY FEATURES OF THE P1210 SMOKE ALARM:
Photoelectric Sensing Technology: 

Photoelectric Sensors are generally more sensitive than ionization sensors in detecting smoldering fires which commonly occur 

in couches or bedding.

OptiPath 360 Technology™: 

Patented technology provides 360° of direct access to the smoke sensor.

Single Test/Silence Button:

 Allows you to test the Alarm or silence nuisance alarms. Testing the Alarm assures you that the unit is functioning correctly and ready 

to protect you and your family. The Alarm can be silenced for up to 9 minutes in the event of a nuisance alarm.

10 Year End of Life Indicator:

 3 horn pulses every 43 seconds alerts you that the unit must be replaced.

Local Alarm Memory: Green LED flashes 3 times every 43 seconds for 24 hours. After 24 hours the unit will chirp rapidly while the Test button is pressed. Memory is 
cleared when the button is released.

Low battery warning: 

The Alarm will sound a “chirp” once per minute when the Smoke Alarm needs to be replaced.

Low battery silence: 

The Alarm can be silenced for 8 hours.

Red Blinking Power Indicator every 6 minutes:

 Confirms that the Smoke Alarm is receiving power

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.

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. 
• 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 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. Red LED flashes rapidly.

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 30 days, but you should replace the Smoke Alarm immediately to continue your protection.

 

Actual service life depends on the Smoke Alarm and the environment in which it is installed. You MUST replace the Smoke Alarm 

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 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.

 Alarms have various limitations. See “Limitations of Smoke Alarms” for details.

USING THE SILENCE FEATURE

The Silence Feature can temporarily quiet an unwanted alarm for up to 9 minutes. To use this feature, press the Test/Silence button on the cover. 

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

. The LED will flash every 10 seconds 

while in silence.

 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.

SILENCING THE LOW BATTERY WARNING

This silence feature can temporarily quiet the Low Battery warning “chirp”. Press the Test/Silence button on the Alarm. The Red light flashes normally, once every 6 
minutes, during Low Battery Warning Silence. After time, the low battery “chirp” will resume.

 Deactivate the Smoke Alarm and replace it immediately.

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 a “chirp” about once a minute, replace the Smoke Alarm.
• 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.

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 floor stairway, and at bottom of basement stairway.

 

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.

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.

HOW TO INSTALL THIS SMOKE ALARM

OPTIONAL LOCKING FEATURE

The optional locking feature is designed to prevent unauthorized removal of the alarm. It is not necessary to 
activate the lock in single-family households where unauthorized alarm removal is not a concern.  

Tools you will need:

  Needle-nose pliers or utility knife • Standard flathead screwdriver

The feature uses a locking pin which is molded into the mounting bracket.  Remove locking pin by using 
needle-nose pliers or a utility knife.

 To permanently remove the locking pin, insert a flathead screwdriver 

between the locking pin and the lock and pry the pin out of the lock.

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.
___________________________________________________________________________________________________________________________

LOCATIONS TO AVOID FOR SMOKE ALARMS

FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE ALARMS IN THESE 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.

• In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the 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 or 

basements.

• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. Keep laundry room Smoke Alarms free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit, preventing it from reaching the sensing chamber.
• In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air spaces, follow the 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 and 12 inches (102 and 305 mm) from the wall/

ceiling line, below typical “dead air” spaces.

ON A PEAKED, GABLED, OR CATHEDRAL CEILING,

 install the 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.

FOLLOW THESE SIMPLE STEPS

1. Hold the mounting bracket against the 

ceiling (or wall) so the two clusters of 
universal mounting holes are aligned 
approximately at the 9:00 and 3:00 
o’clock positions. See image. Choose 
one of the three sets of holes shown, A, 
B or C (see image) and trace around one 
of the sets. Be sure to choose a top and 
bottom slot on opposite sides so you can 
rotate the universal mounting bracket into 
position later. This will make it easier in 
the future to remove the mounting bracket 
without completely removing the screws.

WARNING! Do not install this Smoke Alarm over an existing electrical box. 
Only AC powered units are intended for installation over electrical boxes.

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

holes.

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

you traced.

4. 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.

5. Install the screws but do not tighten completely. Attach the mounting bracket 

by aligning the screws in the open portion of the universal mounting slots and 
rotating the bracket into place. Tighten the screws until they are snug to secure 
the bracket. Do not over tighten.

6. 

Activating the battery. 

Mount alarm to mounting bracket to activate. Once unit 

is activated, it cannot be turned off.

NOTE: After you activate the battery, the power indicator light may flash. 
(If the unit alarms, the light will blink rapidly, and the horn will repeatedly 
sound 3 beeps, pause, 3 beeps.) Once the Smoke Alarm is on the bracket, 
you can rotate the Alarm to adjust the alignment.

7. Test the Smoke Alarm. See “Weekly Testing.”
8. After 10 years of operation or Low Battery 

warning, deactivate the Smoke Alarm: Insert a tool 
below edge where shown and break tab. Then 
slide activation switch to deactivate mode.

NOTE: At end of life or low battery indication (chirp): unit must be put into 
deactivation mode to deactivate remaining stored energy in battery. Unit will 
no longer function once put into this mode. Unit will resist re-mounting.
