Smoke Alarms conform to regulatory requirements,
including ULCS531 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.
INTRODUCTION
Thank you for choosing BRK Brands, Inc. 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.
Key features include:
Smart Technology designed to help reduce unwanted or nuisance alarms.
Single Button Test/Silence eliminates confusion. Depending on what mode the alarm is
in, pushing the button provides different functions such as testing the alarm, silencing
the alarm, re-testing the alarm when in silence and clearing the Latching feature.
Latching Alarm Indicator easily identifies initiating alarm
even after the alarm condition has subsided.
Perfect Mount System includes a gasketless base for easy installation and a new mounting
bracket that keeps the alarm secure over a wide rotation range to allow for perfect
alignment.
Easy Installation/Maintenance features include a large opening in the mounting
bracket for easy access to wiring. A battery pull tab keeps the battery fresh
until the home is occupied. A Side Load Battery Drawer allows for easy battery
replacement without removing the alarm from the ceiling or wall.
Improved UV Resistance keeps the alarm from discoloring over time.
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.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke Alarm is
installed before removing it from the mounting bracket. Failure to turn off the power first
may result in serious electrical shock, injury or death.
• This unit will not alert hearing impaired residents. It is recommended that you install
special units which use devices like flashing strobe lights to alert hearing impaired
residents.
• Installation of this unit must conform to the electrical codes in your area; Articles
210 and 300.3 (B) of NFPA 70 (NEC), NFPA 72, NFPA 101; ICC; SBC (SBCCI); UBC
(ICBO); NBC (BOCA); OTFDC (CABO), and any other local or building codes that
may apply. Wiring and installation must be performed by a licensed electrician.
Failure to follow these guidelines may result in injury or property damage.
• This unit must be powered by a 24-hour, 120V AC pure sine wave 60 Hz
circuit. Be sure the circuit cannot be turned off by a switch, dimmer, or ground fault
circuit interrupter. Failure to connect this unit to a 24-hour
circuit may prevent it from providing constant protection. Unit may be
connected to an arc fault circuit interrupter.
• This Smoke Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4
minutes. If AC power fails and the battery is weak, protection should last for up to 7
days. If AC power fails and the battery is dead or missing, the alarm cannot operate.
• Never disconnect the power from an AC powered unit to stop an unwanted alarm.
Doing so will disable the unit and remove your protection. In the case of a true
unwanted alarm open a window or fan the smoke away from the unit. The alarm will
reset automatically when it returns to normal operation. Never remove the batteries
from a battery operated unit to stop an unwanted alarm (caused by cooking smoke,
etc.). Instead open a window or fan the smoke away from the unit. The alarm will
reset automatically.
• Connect this unit ONLY to other compatible units. See “How To Install This Smoke
Alarm” for details. Do not connect it to any other type of alarm or
auxiliary device. Connecting anything else to this unit may damage it or
prevent it from operating properly.
• The battery compartment resists closing unless a battery is installed. This
warns you the unit will not operate under DC power without a battery.
• The battery compartment resists closing unless a battery is installed. This
warns you the unit will not operate under DC power without a battery.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.
The Mounting Bracket:
To remove the mounting bracket from the Smoke Alarm base, hold
the Smoke Alarm base firmly and twist the mounting
bracket counterclockwise. The mounting bracket installs onto
the junction box. It has a variety of screw slots to fit most boxes.
The Power Connector:
The power connector plugs into a power input block on the
Smoke Alarm. It supplies the unit with AC power.
• The black wire is “hot.”
• The white wire is neutral.
• The orange wire is used for interconnect.
If you need to remove the power connector, turn POWER
OFF first. insert a flat screwdriver blade between the power
connector and the security tab inside the power input block.
Gently pry back the tab and pull the connector free.

The basic installation of this Smoke Alarm is similar whether you want to install one
Smoke Alarm, or interconnect more than one Smoke Alarm. If you are interconnecting
more than one Smoke Alarm, you MUST read “Special Requirements For
Interconnected Smoke Alarms” below before you begin installation.
ELECTRICAL SHOCK HAZARD. Turn off power to the area where you will install this
unit at the circuit breaker or fuse box before beginning installation. Failure to turn off the
power before installation may result in serious electrical shock, injury or death.
1. Remove the mounting bracket from the base, and attach it to the junction box.
Activate the battery back-up by removing the “Pull to Activate Battery Back-
Up” tab. Or, install battery backup. Battery back-up cannot work until you
install the battery in the correct posiion. (Match “+” to “+” and “-” to “-”).
2. Using wire nuts, connect the power connector to the household wiring.
Improper wiring of the power connector or the wiring leading to the power connector
will cause damage to the Alarm and may lead to a non-functioning Alarm.
3. Plug the power connector into the back of the Smoke Alarm.
4. Position the base of the Smoke Alarm over the mounting bracket and turn. The Alarm
will remain secure over a wide rotation range to allow for perfect alignment. When wall
mounting, this will allow fine-tuning on the positioning to compensate
for misaligned wall studs and to keep the wording level. The Alarm can be
positioned over the bracket every 120°. Rotate the Alarm until aligned properly.
5. Check all connections.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Smoke Alarms are
completely installed. Restoring power before installation is complete may result in
serious electrical shock, injury or death.
6. Make sure the Smoke Alarm is receiving AC power. Under normal
operation, the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE
JUNCTION BOX and recheck all connections. If all connections are correct and
the Green power indicator still does not light when you restore
the power, the unit should be replaced immediately.
8. Test each Smoke Alarm. Press and hold the Test/Silence
button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
SPECIAL REQUIREMENTS FOR INTERCONNECTED SMOKE ALARMS
• Failure to meet any of the above requirements could damage the units
and cause them to malfunction, removing your protection.
• AC and AC/DC Smoke Alarms can be interconnected. Under AC power, all units will
alarm when one senses smoke. When power is interrupted, only
the AC/DC units in the series will continue to send and receive signals.
AC powered Smoke Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Smoke Alarm initiated an alarm, see table:
During an Alarm:
On Initiating Alarm(s) Red LED(s) flashes in sync with the horn
On All Other Alarms Red LED is Off
After an Alarm (Latching)
On Initiating Alarm(s) Red LED 2 seconds on/2 seconds off
On All Other Alarms Green LED(s) On, Red LED(s) is Off
On DC power, alarm latch will appear for only 15 minutes in order to conserve power.
Press Test/Silence button to turn off indicator.
You will hear a chirp indicator and then the alarm will go into normal operation.
Compatible Interconnected Units
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will only
work if they are wired to compatible units and all requirements are met. This unit is designed to
be compatible with:

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 accuratelyests the
unit’s operation as required by Underwriters’ Laboratories of Canada(ULC).
• 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” at the end of this manual.
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 button is the
recommended way to test this Smoke Alarm. Press and hold the test 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. When testing a series of interconnected units you must test each unit individually.
Make sure all units alarm when each one is tested.
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.
Use only the replacement batteries listed below. The unit may not operate properly with other
batteries. Never use rechargeable batteries since they may not provide a constant charge.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum the outside of the
Smoke Alarm using your household vacuum’s soft brush attachment. Test the Smoke
Alarm. 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 back-up becomes weak, the Smoke Alarm will “chirp” about
once a minute (the low battery warning). This warning should last 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: Duracell #MN1604, (Ultra) #MX1604; Eveready (Energizer) #522, Eveready (Energizer)
#1222. You may also use a Lithium battery like the Ultralife U9VL-J, U9VL-J-P for longer service
life between battery changes. These batteries are available at many local retail stores.
Actual battery 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.
• 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 disconnect the AC power to quiet an unwanted alarm. Disconnecting
the power disables the Alarm so it cannot sense smoke. This will remove 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.
• ELECTRICAL SHOCK HAZARD: Attempting to disconnect the power connector from
the unit when the power is on may result in electrical shock, serious injury or death.
When an interconnected system of AC powered units is in alarm, the alarm indicator light on
the unit(s) that initiated the alarm will blink rapidly. It will remain OFF on any remaining units.
If the unit alarms and you are certain that the source of smoke is not a fire—cooking
smoke or an extremely dusty furnace, for example—open a nearby window or door and
fan the smoke away from the unit. Use the Silence Feature to silence the alarm. This will
silence the alarm, and once the smoke clears the unit will reset itself automatically.
IF THIS SMOKE ALARM SOUNDS, Continued
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.

“LATCHING ALARM” INDICATOR
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing or weak batteries, 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 install a
fresh battery, then test the Smoke Alarm again. If it fails to test properly when you use the
Test/Silence button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” once a 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 it is receiving AC power from the
household current.
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 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 the first-to-second floor stairway, and at the bottom of the 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.
The Latching Alarm Indicator is automatically activated after an Alarm is exposed to
alarm levels of smoke. After smoke levels drop below alarm levels, the red LED will
be On for 2 seconds/Off for 2 seconds, repeatedly. This feature helps emergency
responders, investigators, or service technicians identify which unit(s) in your home were
exposed to alarm levels of smoke after the condition has subsided. The Latching Alarm
Indicator stays ON until you reset it by pressing the Test/Silence button. The Latching
Alarm Indicator is also reset when AC and DC power is removed from the Alarm.
USING THE SILENCE FEATURE
The Silence Feature on this unit can temporarily quiet an unwanted alarm for up to 10 minutes.
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. 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.
To silence Smoke Alarms in an interconnected series:
1. 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 rapidly. The red LED
will be Off on all other non-initiating alarms. No audible sound will be heard.
The unit will exit “silence mode” in approximately 10 minutes.
2. While the unit is in “silence mode”, pressing and holding the Test/Silence
button for approximately 10 seconds will test the unit. After testing, the
unit will re-enter “silence mode” and the 10-minute timer is reset.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, 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. Clean a laundry room unit frequently to keep it 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 sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) 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 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 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.
ABOUT SMOKE ALARMS
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. However, they do not 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. 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.
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 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 unit to install, refer to NFPA (National Fire Protection Association) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection
Association, One Batterymarch Park, Quincy, MA 02269-9101.
Local building codes may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care facilities, or group homes of any
kind—even if they were once single-family homes. 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.
The following information applies to all four building types below:
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. Refer to NFPA 101 (Life Safety Code) or NFPA
72 (National Fire Alarm Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households.”
1. Single-Family Residence:
Single family home, townhouse. It is recommended Smoke Alarms be installed on
every level of the home, in every bedroom, and in each bedroom hallway.
2. Multi-Family or Mixed Occupant Residence:
Apartment building, condominium. This Smoke Alarm is suitable for use in individual apartments or
condos, 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.
3. Institutions:
Hospitals, day care facilities, long-term health care facilities. This Smoke Alarm is suitable
for use in individual patient sleeping/resident rooms, 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.
4. Hotels and Motels:
Also boarding houses and dormitories. This Smoke Alarm is suitable for use inside
individual sleeping/resident rooms, 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.
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 the Alarms. 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 floor or area of the dwelling. For example,
a stand-alone unit on the second floor 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
dwelling. Even with a unit on every floor, 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.

INSTALLING SMOKE ALARMS IN MOBILE HOMES & RVS
For minimum security install one Smoke Alarm as close to each sleeping area as possible.
Formoresecurity,put one unit in each room. Many older mobile homes (especially those
builtbefore1978) have little or no insulation. If your mobile home is not well insulated,
or if you areunsure of the amount of insulation, it is important to install units on inside
walls only. SmokeAlarms should be installed wheretemperatures normally remain
between 4˚ C (40˚ F) and 38˚ C(100˚ F).WARNING: Test units used in RVs after the
vehicle has been in storage, beforeevery trip, and once a week while in use.
Failure to test units used in RVs as describedmay remove your protection.
This equipment should be installed in accordance with NFPA (National Fire ProtectionAssociation)
72 and 101. National FireProtection Association, One Batterymarch Park,Quincy,MA 02269-
9101 U.S.A. Additional local building and regulatory codes may applyin your area.
Always check compliance requirements before beginning any installation.
AGENCY PLACEMENT RECOMMENDATIONS
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.
Smoke alarms should be installed in accordance with National Building Code of Canada
(NBCC), the National Fire Code of Canada, CAN/ULC S553 and local requirements.
NFPA 72 (National Fire Code)
Smoke Alarms shall be installed in each separate sleeping room, outside each sleeping
area in the immediate vicinity of the bedrooms and on each additional story of the family
living unit, including basements and excluding crawl spaces and unfinished attics.
In new construction, Alarms shall be so arranged that operation of any one
Alarm shall cause the operation of all Alarms within the dwelling.
Smoke Detection-Are More Smoke Alarms Desirable? The required number of Smoke
Alarms might not provide reliable early warning protection for those areas separated by a door
from the areas protected by the required Smoke Alarms. For this reason, it is recommended
that the householder consider the use of additional Smoke Alarms for those areas for increased
protection. The additional areas include the basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the required Smoke Alarms. The installation of Smoke
Alarms in kitchens, attics (finished or unfinished), or garages is not normally recommended,
as these locations occasionally experience conditions that can result in improper operation.
LOCKING FEATURES
The locking features are designed to discourage unauthorized removal of the battery or alarm. It is not necessary to activate the locks in single-family households where
unauthorized battery or alarm removal is not a concern.
These alarms have two separate locking features: one to lock the battery compartment, and the other to lock the Smoke
Alarm to the mounting bracket. You can choose to use either feature independently or use them both.
Tools you will need: • Needle-nose pliers or utility knife • Standard Flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Using needle nose pliers or a utility knife,
remove one or both pins from the mounting bracket, depending on how many locking features you want to use.
To permanently remove either lock insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
Once the Smoke Alarm is installed, you must disconnect it from the AC power before
unlocking the battery compartment.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke Alarm is
installed before removing it from the mounting bracket. Failure to turn off the power first
may result in serious electrical shock, injury or death.
Always discharge the branch circuit before servicing an AC or AC/DC Smoke Alarm.
First, turn off the AC power at the circuit breaker or fuse box. Next, remove the battery from
Smoke Alarms with battery back-up. Finally, press and hold the test button for 5-10 seconds
to discharge the branch circuit.
1. Remove the Smoke Alarm from the mounting bracket.
If the unit is locked to the bracket, see the
section “To Unlock the Mounting Bracket.”
2. Disconnect the power connector by gently prying
it away from the back of the Smoke Alarm.
3. Score the area around the locking pin to break the
seal. Insert a flathead screwdriver under the head of
the locking pin or use a needle nose pliers to gently pry
it out of the battery compartment lock. (If you plan to
re-lock the battery compartment, save the locking pin.)
4. To relock the battery compartment, close the
battery door and reinsert locking pin in lock.
5. Reconnect the power connector to the back of the
Smoke Alarm, reattach the Smoke Alarm to the
mounting bracket, and restore the power.
When replacing the battery, always test the Smoke Alarm before relocking the battery
compartment.
