1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps, a 1.5 second pause, and three long beeps repeating.
The red LED blinks in time with the alarm pattern only on the alarm(s) that detected the hazard (initiating
alarm).
• Alert small children in the home as well as anyone else that might have difficulty recognizing the
importance of the alarm sounding or that might have difficulty leaving the area without help.
• Plan two ways out! Leave immediately by your escape plan. Don’t waste time getting dressed or
picking up valuables.
• While leaving, don’t open any inside door without first feeling its surface. If hot, or if you see
smoke seeping through cracks, don’t open that door! Instead, use your alternate exit. If the inside
of the door is cool, place your shoulder against it, open it slightly and be ready to slam it shut if
heat and smoke rush in.
• If the escape route requires you to go through smoke, stay close to the floor where the air is
cleaner. Crawl if necessary, and breathe shallowly through a cloth, wet if possible.
• Once outside, go to your selected meeting place and make sure everyone is there.
• Call the fire department or 911 from your cell phone outside, or from your neighbor’s home-not
from yours!
• Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

WARNING: ACTUATION OF YOUR CO ALARm INDICATES THE PRESENCE OF CARBON mONOxIDE
(CO) WHICH CAN KILL YOU. IF ALARm SIGNAL SOUNDS:
1) Operate the Test/Hush button. NOTE: Pressing the button on the initiating CO or combination smoke/CO unit
in your system will silence the alarm notification, including all interconnected units. If the CO or combination
smoke/CO unit goes into alarm mode again within six minutes, it is sensing high levels of CO which can quickly
become a dangerous situation.
2) Call your emergency services (Fire Department or 911). EmERGENCY PHONE #:
_______________________
3) Immediately move to fresh air — outdoors or by an open door / window. Do a head count to check that all
persons are accounted for. Alert small children in the home as well as anyone else that might have difficulty
recognizing the importance of the alarm sounding or that might have difficulty leaving the area without help.
Do not reenter the premises or move away from the open door/window until the emergency services respond
-
ers have arrived, the premises have been aired out, and your alarm remains in its normal condition.
4) After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified
appliance technician to investigate sources of CO from fuel burning equipment and appliances, and to inspect
for proper operation of equipment.
If problems are identified during this inspection, have the equipment serviced immediately. Note any com
-
bustion equipment not inspected by the technician and consult the manufacturer’s instructions, or contact the
manufacturer directly for more information about CO safety and the equipment. Make sure that motor vehicles
are not, or have not been, operating in a garage attached or adjacent to the residence. Never restart the
source of a CO problem until it has been corrected. Never ignore the sound of the alarm! NOTE: See Section
RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

6. Limitations Of Smoke Alarms
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• Life safety from fire in residential occupancies is based primarily on early notification to occupants of the
need to escape, followed by the appropriate egress actions by those occupants.
• There are situations where a smoke alarm may not be effective to protect against fire as stated in the
NFPA Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
• Fire warning systems for dwelling units are capable of protecting about half of the occupants in poten-
tially fatal fires. A smoke alarm may not be effective in some situations, such as during incendiary fires
where the fire grows so rapidly that an occupant’s egress is blocked even with properly located smoke
alarms, or when victims are intimate with the fire (for example, when a person’s clothes catch fire while
cooking), too old or young, or physically or mentally impaired such that they cannot escape even when
warned early enough that escape should be possible. For these people, additional strategies such as
protection-in-place or assisted escape or rescue are necessary. *
• This model meets the latest residential smoke alarm standards, which includes enhanced resistance
to nuisance alarms from cooking. Industry experts recommend that both ionization and photoelectric
smoke alarms be installed to help ensure optimal detection of the various types of fires that can occur
within the home. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming
fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles
(associated with slow smoldering fires) sooner than ionization alarms.
• A battery powered alarm must have a battery of the specified type, in good condition and installed
properly (this model includes two AA replaceable backup batteries).
• This device requires a continuous supply of electrical power from a healthy battery or AC connection,
depending on the model. It will not work without power.
• Smoke alarms must be tested regularly to make sure the battery and the alarm circuits are in good
operating condition.
• Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms may
not sense fires starting in chimneys, within walls, on roofs, on the other side of a closed door or other
obstructions.
• If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
• The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For optimal detection,
a smoke alarm should be installed in each sleeping area on every level of a home.
* Reference National Fire Protection Association (NFPA) standard 72
10
7. Recommended Locations For Smoke Alarms
• Locate smoke alarms in all sleeping areas. Try to monitor the exit path as the bedrooms are usually
farthest from the exit. If more than one sleeping area exists, locate additional alarms in each
sleeping area.
• Locate additional alarms in stairways, because stairways act like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances are operated (i.e. portable heaters or
humidifiers).
• Locate an alarm in every room where someone sleeps with the door closed. The closed door may
prevent an alarm not located in that room from waking the sleeper.
• Smoke, heat, and combustion products rise to the ceiling and spread horizontally. Mounting the
smoke alarm on the ceiling in the center of the room places it closest to all points in the room.
Ceiling mounting is preferred in ordinary residential construction.

• For mobile home installation, select locations carefully to avoid thermal barriers that may form at
the ceiling. For more details, see MOBILE HOME INSTALLATION section.
• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a
maximum of 12” (30.5 cm) below the ceiling.
• Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more
than 30 feet (9.1 m) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft (0.9m) of the highest
point (measured horizontally).
This equipment should be installed in accordance with the National Fire Protection Association’s 72
(National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
mobile Home Installation
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as
recommended above. In older mobile homes that are not well insulated compared to present stan-
dards, extreme heat or cold can be transferred from the outside to the inside through poorly insulated
walls and roof. This may create a thermal barrier which can prevent the smoke from reaching an alarm
mounted on the ceiling. In such units, install the smoke alarm on an inside wall with the top edge of the
alarm a maximum of 12” (30.5 cm) below the ceiling.
If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and
ceiling are either hot or cold compared to the room air temperature, install the alarm on an inside wall.
NFPA 72 (National Fire Protection Association) requires smoke alarms be installed in each sleeping
area.
WARNING: TEST YOUR ALARm OPERATION AFTER mOBILE HOmE HAS BEEN IN STOR-
AGE OR UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.
13
8. Locations To Avoid
(See Figures 7-A, 7-B, & 7-C for recommended locations)
• In the garage. Products of combustion are present when you start your automobile.
• Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm
silence feature and should not be installed within 6 ft of cooking appliances.
• Do not install within 6 ft of heating appliances.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40ºF or rise above 100ºF, such as garages and
unfinished attics.
• In dusty areas. Dust particles may cause nuisance alarms or a failure to alarm.
• In very humid areas (above 95% RH, non-condensing) as moisture or steam can cause nuisance
alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (.9m) of the door to a bathroom containing a tub
or shower, forced air supply ducts used for heating or cooling, ceiling or whole house ventilating
fans, or other high air flow areas.
• Near lights. Electronic “noise” generated by the lights may cause nuisance alarms.
• Do not install near vents, flues, or chimneys.
• Do not install near fans, doors, windows or areas directly exposed to the weather.
• Avoid installing where the unit will be exposed to direct sunlight.

9. Wiring / Installation / Activation
NOtE: A dust cover has been installed on the alarm. Keep the
dust cover on until all construction has been completed for at
least 24 hours (drywall, painting, varnishing, mounting plate
install, etc). Retain the dust cover and re-install it to protect the
alarm during future construction projects. Construction dust and
chemicals can cause contamination and false alarms.
wARNiNG: dUSt cOvER MUSt bE REMOvEd fOR ALARM tO OPERAtE.
NOtE:
To avoid false low battery chirping pull out the battery pull tab first to activate the backup batteries
(see Figure 9-A). Battery activation is confirmed with a beep. If the beep does not occur when the battery
pull tab is removed, remove the batteries and reinstall them. Confirm the battery activation beep.
wiring Requirements
• This alarm should be installed on a UL Listed or recognized junction box. All connections should be
made by a qualified electrician and all wiring used shall be in accordance with articles 210 and 300.3(B)
of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdiction
in your area. The multiple station interconnect wiring to the alarms must be run in the same raceway or
cable as the AC power wiring. In addition, the resistance of the interconnect wiring shall be a maximum
of 10 ohms.
• The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet.
• The appropriate power source is 120 Volt AC Single Phase supplied from a non-switchable circuit.
• Smoke alarms are not to be used with detector guards unless the combination (alarm and detector
guard) has been evaluated and found suitable for that purpose.
• Kidde alarms are not designed, agency tested or certified for recessed mounting and should not be
installed in this manner. Recessed mounting impedes smoke entry into the smoke chamber, which may
prevent the alarm from sounding in a timely manner. This could endanger the lives of occupants in the
residence. Kidde alarms are designed, tested and certified for wall (if applicable) and ceiling surface
mount only.

wiring instructions for Ac quick connector harness
cAUtiON: Turn off the main power to the circuit before wiring the alarm.
• For alarms that are used as single station, DO NOT CONNECT THE RED WIRE TO ANYTHING. Leave the red
wire insulating cap in place to make certain that the red wire cannot contact any metal parts or the electrical box.
• When alarms are hardwire interconnected, all interconnected units must be powered from a single circuit.
• A maximum of 24 Kidde Safety devices may be interconnected in a multiple station arrangement. The intercon-
nect system should not exceed the NFPA interconnect limit of 12 smoke alarms and/or 18 alarms total (smoke,
CO, Smoke/ CO Combination, heat, etc.). With 18 alarms interconnected, it is still possible to interconnect up to a
total of 6 remote signaling devices and/or relay modules.
• Figure 9-B illustrates interconnection wiring. Improper connection will result in damage to the alarm,
failure to operate, or a shock hazard.
• Make certain alarms are wired to a continuous (non-switched) power line.

NOtE: Use standard UL Listed household wire (as required by local codes) available at all electrical
supply stores and most hardware stores.
NOtE: AC power should be turned off at this stage.
• For best results to minimize nuisance
alarms, interconnected alarms should
be on a dedicated line. If not on a
dedicated line, it is suggested that the
smoke alarms share a lighting load
circuit that does not have a dimmer
associated with it. If receptacles
must be placed on the same line it is
suggested that they be placed ahead
of the smoke alarms (see Figure 9-C).
This will prevent large voltage drops
from occurring between the first and
last alarm in the circuit.
• After selecting the proper location for
your alarm, and wiring the AC QUICK
CONNECTOR harness as described
previously, attach the mounting
bracket to the electrical box. To ensure
aesthetic alignment of the alarm with
the hallway, or wall, the “A” line on the
mounting bracket should be parallel
with the hallway when ceiling mount
-
ed, or horizontal when wall mounted.
(See Figure 9-D)
• Pull the AC QUICK CONNECTOR
through the center hole in the mount
-
ing bracket and secure the bracket,
making sure that the
mounting
screws are positioned in the small
ends of the keyholes before
tightening the screws.
• Plug the AC QUICK CONNECTOR
into the back of the unit, making
sure that the connector snaps
into place. Then push the excess
wire back into the electrical box
through the hole in the center of the mounting bracket.

.
WARNING: FAILURE TO PROPERLY CONNECT AC POWER AND INSTALL BATTERIES IN THE
CORRECT ORIENTATION WILL PREVENT PROPER OPERATION OF THIS ALARm AND WILL PRE-
VENT ITS RESPONSE TO FIRE HAzARDS.
10. Operation And Testing
This model meets the latest residential smoke alarm standards, which includes enhanced resistance
to nuisance alarms from cooking.
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). When
products of combustion (smoke) are sensed, the unit sounds a loud alarm. See Section 1 for alarm
signal descriptions.
Testing
WARNING: Do not attempt to test this unit with retail “canned smoke” products. Those products
are intended for use by trained professionals and produce inconsistent results when misused.
Over-application of canned smoke can permanently damage the alarm.
SELF-TESTING
This model is equipped with internal, self-testing components that are always checking to ensure the
device is operating as expected. (Weekly manual testing is still required. See below.)
mANUAL TESTING
NOTE: When pushing the Test button, use only your finger or thumb. Using any other instrument(s)
(such as a broom handle) is strictly prohibited, as it may damage the alarm.
Test your alarm weekly by pressing and releasing the button quickly. A quick beep will confirm the button
has been pushed followed by the test sequence. See Other Alarm Visual and Audible Indicators table. The
alarm (and any interconnected units) will sound if the electronic circuitry, horn, and batteries are working. If
the alarm does not sound, or gives erratic or low volume sound, the unit must be replaced.
19
WARNING: DUE TO THE LOUDNESS OF THE ALARm, ALWAYS STAND ABOUT 2.5 FEET
AWAY FROm THE UNIT OR USE EAR PROTECTION WHEN TESTING.
WARNING: DO NOT USE AN OPEN FLAmE TO TEST YOUR ALARm, YOU COULD DAmAGE
THE ALARm OR IGNITE COmBUSTIBLE mATERIALS AND START A STRUCTURE FIRE.
Chirping
When End of Unit Life or Low Battery chirping begins, you can temporarily silence these chirps
by pressing the button. Other fault/error chirps cannot be silenced. Take appropriate action as
described in the Troubleshooting Guide.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE. SEVEN (7)
DAYS AFTER END OF UNIT LIFE BEGINS, THE NOTIFICATIONS CANNOT BE SILENCED, AND
SmOKE DETECTION CANNOT BE GUARANTEED. REPLACE ImmEDIATELY!
11. Recognizing Nuisance Alarms
Smoke Nuisance
This model meets the latest residential smoke alarm standards, which includes enhanced resistance
to nuisance alarms from cooking.
HUSH
Tm
: If you know why the alarm is sounding, and you can verify that it is not a life threatening sit-
uation, you can push the button on the initiating unit to silence the alarm for 8-10 minutes. If the smoke
is not too dense, that unit, and all interconnected units will silence. After the Hush
TM
period, the smoke
alarm will automatically reset and sound the alarm if particles of combustion are still present. You can
use Hush
TM
repeatedly until the air has been cleared of the condition causing the alarm.
NOTE: Dense smoke will override Hush
Tm
and sound a continuous alarm. If no fire is present,
check to see if one of the reasons listed in “Locations to avoid” may have caused the alarm. If a
fire is discovered, get out and call the fire department or 911.
Cigarette smoke will not normally cause the unit to alarm, unless the smoke is blown directly into the
alarm. Combustion particles from cooking may set off the alarm if it is located too close to a cooking
appliance. Large quantities of combustible particles are generated from spills or when broiling. Using
the fan on a range hood which vents to the outside (non-recirculating type) will also help prevent nui-
sance alarms from occurring by removing these combustible products from the kitchen.
Carbon monoxide (CO) Nuisance
wARNiNG: This unit does not detect CO, but it will transmit a CO alarm signal from an intercon-
nected CO or Smoke/CO combination alarm. It is impossible to determine the source of a CO alarm
using sight or smell. Always consider a CO alarm event as dangerous.
•
Pushing the button on the initiating CO or Smoke/CO combination alarm will silence that alarm and all
compatible interconnected units.
• Pushing the button on any hard-wire smoke alarm will do nothing to silence an interconnected CO alarm.
20
12. Battery Backup
This alarm is powered with AC power, but also contains two
replaceable AA backup batteries. Under normal conditions,
fresh batteries will last at least one year.
In order to access the battery compartment, the wiring harness
needs to be removed. To release the wiring harness, press down
on the tab as shown in Figure 12-A.
NOTE: Constant exposure to high or low humidity or temperatures
may reduce battery life.
WARNING: THE ALARm IS SEALED AND THE COVER IS NOT REmOVABLE!
Low Battery
This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point
where it can no longer provide adequate power for all alarm functions, the low battery condition
will occur. See Troubleshooting Guide. The batteries must be replaced within 7 days of the first
occurrence of the “Low Battery Warning” to provide continuous alarm detection.
Replace batteries with one of the following approved brands:
Energizer E91, Gold Peak 15A or Golden Power GLR6A.
These batteries can be purchased at your local retailer.
WARNING: Use only the batteries specified. Use of different
batteries may have a detrimental effect on the alarm. Do not mix old and
new batteries. Do not mix alkaline, standard, or rechargeable batteries.
NOTE:
Do not use lithium batteries in this unit. A good safety measure
is to replace the batteries at least once a year, or at the same time
you change your clocks for daylight saving time. Loss of AC power and a missing or improperly
installed battery will render the unit inoperable.
WARNING: FAILURE TO PROPERLY CONNECT AC POWER AND INSTALL BATTERIES IN THE
CORRECT ORIENTATION WILL PREVENT PROPER OPERATION OF THIS ALARm AND WILL
PREVENT ITS RESPONSE TO FIRE HAzARDS.

13. Cleaning Your Alarm
Your Alarm Should be Cleaned at Least Once a Year
You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum
cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm.
The outside of the alarm can be wiped with a clean, dry cloth. Do not use water, detergents or cleaners
as they may damage the alarm.
NOtE: Do not insert fingers or cleaning items under the shield during cleaning.
If the alarm is in Fault mode, the alarm may be in need of cleaning. After cleaning, press the button.
If the fault does not clear, the alarm needs to be replaced.
• Never use detergent or other solvents to clean the unit.
• Avoid spraying air freshener, hair spray, or other aerosols near the alarm.
• Do not use a hair dryer to clean the alarm, as it may damage the alarm and impact performance.
• Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect
smoke.
• Never attempt to disassemble the unit to clean inside. This action will void your warranty.
WARNING: REINSTALL THE ALARm AS SOON AS POSSIBLE TO ENSURE CONTINUOUS
DETECTION.

14. Good Safety Habits
Develop and Practice a Plan of Escape
Prepare and practice a home escape plan twice a year, including drills at night. Know two ways out
of every room (door & window) and identify a meeting place outside the home where everyone will
gather once they have exited the residence. When two people have reached the meeting place, one
should leave to call 911 while the second person stays to account for additional family members. Estab-
lish a rule that once you’re out, you never re-enter under any circumstance!
• Make a floor plan indicating all doors and windows and at least two (2) escape routes from each
room. Stories above ground level may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire
and where to meet after they leave the house.
• Ensure that small children hear the alarm and wake when it sounds. They must wake up in order to
execute the escape plan. Practice allows all occupants to test your plan before an emergency. You
may not be able to reach your children. It is important they know what to do.
• Familiarize everyone with the sounds of the smoke alarm and train them to leave your home when
they hear it.
• Current studies have shown smoke alarms may not awaken all sleeping individuals, and that it is
the responsibility of individuals in the household that are capable of assisting others to provide
assistance to those who may not be awakened by the alarm sound, or to those who may be inca-
pable of safely evacuating the area unassisted.
• Install and maintain fire extinguishers on every level of the home and in the kitchen, basement and
garage. Know how to use a fire extinguisher prior to an emergency.
23
Fire Prevention
Never smoke in bed or leave cooking food unattended. Teach children never to play with matches or
lighters! Train everyone in the home to recognize the smoke alarm pattern and to leave the home using
their escape plan when it’s heard. Know how to do “Stop, Drop and Roll” if clothes catch on fire, and
how to crawl low under smoke. Install and maintain fire extinguishers on every level of the home and in
the kitchen, basement and garage.
NFPA (National Fire Protection
Association)
Fire Safety in the Home: NFPA 72 is
intended to provide reasonable safety for
persons in family living units. Reasonable
fire safety can be produced through the
following three-point program: (1) Minimiz-
ing fire hazards (2) Providing fire-warning
equipment (3) Having and practicing an
escape plan.
Smoke Detection – Are more 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 resident 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 attics (finished or unfinished), garages, or
within 6’ of a heating or cooking appliance is not normally recommended, as these locations
occasionally experience conditions that can result in improper operation. *
* Reference National Fire Protection Association (NFPA) standard 72
For your information, the National Fire Protection
Association’s Standard 72 reads: Where required
by other governing laws, codes, or standards for a
specific type of occupancy, approved single and
multiple-station smoke alarms shall be installed as
follows:
1. In all sleeping rooms and guest rooms
2. Outside of each separate dwelling unit sleeping
area, within 21 ft (6.4 m) of any door to a sleeping
room, with the distance measured along a path
of travel
3. On every level of a dwelling unit, including
basements
4. On every level of a residential board and care
occupancy (small facility), including basements
and excluding crawl spaces and unfinished attics
5. In the living area(s) of a guest suite
6. In the living area(s) of a residential board and
care occupancy (small facility)

California State Fire marshal
Early warning fire 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 the bedrooms), heat or smoke detectors in the living rooms, dining rooms,
bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage rooms, basements and
attached garages.
