Smoke Alarm Procedure
NEVER IGNORE THE SOUND OF THE ALARM!
The smoke alarm takes precedence when both smoke
and carbon monoxide are present.
Determining what type of alarm has sounded is easy with your
Combination Smoke/CO Alarm. The voice message warning system
will inform you of the type of situation occurring. Refer to the
Features section for a detailed description of each alarm pattern.
What To Do If The Alarm Sounds
When the smoke alarm sounds:
Smoke alarms are designed to minimize false alarms. Cigarette
smoke will not normally set off the alarm, unless the smoke is
blown directly into the alarm. This unit contains nuisance alarm
protection, which will reduce the impact of cooking particles.
This unit contains nuisance alarm protection, which will reduce
the impact of cooking particles. When cooking, large quantities
of combustible particles can be generated by spills and broiling.
These combustible particles may set off the alarm if located too
close to the cooking area. Careful location of the unit away from
the kitchen area and using a fan which vents to the outside
through the range hood, (non-recirculating type), will maximize
nuisance alarm protection. Using the fan on a range hood which
vents to the outside (non- recirculating type) will also help remove
these combustible products from the kitchen.
If the alarm sounds, check for fires first. If a fire is discovered follow
these steps. Become thoroughly familiar with these items, and
review with all family members!
• Alert small children in the home. Children sleep very sound
and may not be awakened by the sound of the smoke
alarms.
What to do When the Alarm Sounds
Smoke alarm pattern is 3 long beeps, repeating,
followed by “Fire! Feu!”

5
• Leave immediately using one of your planned escape routes.
Every second counts, don’t stop to get dressed or pick up
valuables.
• Before opening inside doors look for smoke seeping in
around the edges, and feel with the back of your hand. If the
door is hot use your second exit. If you feel it’s safe, open
the door very slowly and be prepared to close immediately if
smoke and heat rush in.
• If the escape route requires you to go through smoke, crawl
low under the smoke where the air is clearer.
• Go to your predetermined meeting place. When two people
have arrived one should leave to call 911 from a neighbor’s
home, and the other should stay to perform a head count.
• Do not reenter under any circumstance until fire
officials say that it is safe to do so.
• There are situations where a smoke alarm may not be
effective to protect against fire as noted by the NFPA
Standard 72. For instance:
- Smoking in bed
- Leaving children unsupervised
- Cleaning with flammable liquids, such as gasoline
- Fires where the victim is intimate with a flaming
initiated fire; for example, when a person’s
clothes catch fire while cooking
- Fires where the smoke is prevented from reaching the
detector due to a closed door or other
obstruction
- Incendiary fires where the fire grows so rapidly that
an occupant’s egress is blocked even with properly
located detectors
What to do When the Alarm Sounds
Smoke alarm pattern is 3 long beeps, repeating,
followed by “Fire! Feu!”

1. Immediately move to fresh air – outdoors or by an open
door/window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises nor move away
from the open door/window until the emergency services
responders have arrived, the premises have been aired out,
and your alarm remains in its normal condition.
2. Call your local emergency service.
(fire department or 911)
Never restart the source of a CO problem until it has been
corrected. Never ignore the sound of the alarm!
If the alarm is sounding, pressing the test/reset button
will terminate the alarm. If the CO condition that caused
the alert in the first place continues, the alarm will
reactivate. If the unit alarms again within six minutes, it
is sensing high levels of CO which can quickly become a
dangerous situation.
WARNING: Activation of the CO alarm
indicates the presence of Carbon Monoxide (CO)
which can kill you.
Carbon Monoxide Alarm Procedure
What to do When the Alarm Sounds
Carbon monoxide (CO) alarm pattern is 4 quick beeps
repeating every 5 seconds, followed by “Warning!
Carbon Monoxide! Monoxyde de carbone!”

Alarm Features
• Independent smoke and carbon monoxide sensors.
• The smoke alarm takes precedence when both smoke and
carbon monoxide are present.
• Alarm/voice message warning system that alerts you to the
following conditions in the manner described below, thus
eliminating any confusion over which alarm is sounding:
– FIRE: The alarm/voice pattern is three long alarm beeps followed
by the verbal warning message “Fire! Feu!” This pattern is
repeated until the smoke is eliminated. The red LED will flash
along with beeps.
– CARBON MONOXIDE: The alarm/voice pattern is four short
alarm beeps followed by the verbal warning message “Warning,
carbon monoxide! Monoxyde de carbone!” After four minutes
the alarm/voice pattern will sound once every minute until the
unit is reset, or the CO eliminated. The red LED will flash while
in alarm/voice mode.
– LOW BATTERY: When the batteries are low and need replacing
the red LED will flash and the unit will “chirp” one time,
followed by the warning message “Low battery! Pile Faible!”
This cycle will occur once every minute for the first hour. After
the first hour the red LED will continue to flash every minute
accompanied by only the “chirp” sound. The voice message
“Low battery” will sound once every fifteen minutes during the
chirp-only cycle. This will continue for at least seven days.
• One “chirp” every 30 seconds is an indication that the alarm is
malfunctioning. If this occurs call the consumer hotline at
1-800-880-6788.

Smoke Alarm
The smoke alarm monitors the air for combustion particles that
are produced when something is burning or smoldering. When
combustion particles in the smoke sensor reach a specified
concentration, the alarm/voice message warning system will sound,
and be accompanied by the flashing red LED.
The smoke alarm takes precedence when both smoke and
carbon monoxide are present.
NFPA 72 states: 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. Fire warning systems for dwelling units are capable of
protecting about half of the occupants in potentially fatal fires.
Victims are often intimate with the fire, 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, other strategies such as protection-in-place or assisted
escape or rescue are necessary.
Smoke alarms are devices that can provide early warning of
possible fires at a reasonable cost; however, alarms have sensing
limitations. Leading authorities recommend that both ionization and
photoelectric smoke alarms be installed to help ensure maximum
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 smouldering fires) sooner than ionization
alarms.
A battery-powered alarm must have a battery of the specified type,
in good condition and installed properly.

13
AC powered alarms (without battery backup) will not operate if the
AC power has been cut off, such as by an electrical fire or an open
fuse.
Smoke alarms must be tested regularly to make sure the batteries
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, in walls, on roofs, on the other side of a closed door or
on a different floor.
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 maximum protection, a smoke alarm should be
installed in each sleeping area on every level of a home.
Although smoke alarms can help save lives by providing an early
warning of a fire, they are not a substitute for an insurance policy.
Home owners and renters should have adequate insurance to
protect their lives and property.
Carbon Monoxide Alarm
The carbon monoxide (CO) alarm monitors the air for the presence
of CO. It will alarm when there are high levels of CO present, and
when there are low levels of CO present over a longer period of
time. When a CO condition matches either of these situations,
the alarm/voice message warning system will sound and be
accompanied by the flashing red LED. The carbon monoxide sensor
uses an electrochemical technology.

Installation Guide
How to Install
1. Remove all your new Kidde wireless interconnect devices from
their respective packages and place them in front of you.
2. Find the eight-position DIP switch located inside the battery
compartment (see Figure 1).
3. Select one of the units. You will define the ID pattern of your
system by positioning the switches of the DIP switch in a random
pattern. The ID pattern will need to be the same for each alarm.
This ID pattern will differentiate your alarm system from similar
systems nearby. Do not use the default ID pattern that your units
are shipped with.
4. Use a pen or pencil to change the switches in each of the Kidde
wireless devices to match the pattern you selected in Step 3.
Ensure that the pattern sequence is not reversed.
5. Power each unit after setting the ID pattern by installing the
batteries (see the Installing Batteries section). The alarms only
read the ID that has been set when they are first supplied power.

6. Push and hold the test button on each unit for at least five
seconds, or until all the devices produce an alarm. If all the units
do not produce an alarm, refer to the Troubleshooting Guide at
the end of the User Guide.
CAUTION: Due to the loudness of the alarm, always stand
an arm’s length away from the unit when testing.
7. Install the alarm in accordance with the User Guide as described
in the Where to Mount the Alarm section and repeat Step 6.
Since wireless communication can be interrupted by a number
of factors, you must test your alarms weekly to ensure proper
communication between alarms.
If your Kidde smoke alarms enter smoke alarm mode, first check
for a fire. If a fire does not exist and the test buttons have not
been activated on any of the units, it is likely that you are receiving
interference from a similar system nearby. In this case, repeat the
above steps and select a different DIP switch pattern. Be sure to
remove the batteries before changing the switch positions.
The interconnect system should not exceed the NFPA interconnect
limit of 12 smoke alarms.
Kidde wireless alarm model KN-COSM-B-RF-CA CAN ONLY
BE interconnected with other Kidde wireless alarms, model
KN-COSM-B-RF-CA.
To help identify the date to replace the alarm, a space has been
designated on the product label affixed to the back of the alarm.
Write the “replace by date” (ten years from initial power up) in
permanent marker on the label (see Alarm Replacement section for
additional information).

Installing Batteries
Batteries were not installed at the factory and must be installed for
the unit to operate.
Install the three AA batteries in the back of the smoke/CO alarm.
• Open battery door by lifting up on the lip at the bottom edge of
the alarm.
• The battery polarity markings on the bottom of the battery
compartment must be adhered to.
• Batteries must be installed in the sequence shown above.
If batteries seem difficult to install, they’re not being installed in
the proper sequence.
• The Smoke/CO alarm will not engage the attachment stud (see
page 22) unless all three batteries are installed and the battery
door is closed. Removal of any or all batteries will render the
smoke/CO alarm inoperative!
• After the batteries are correctly installed the unit will beep once,
the red LED will flash, “Push Test Button” will be played. The
green LED will flash immediately after power is applied, and then
will flash every 30 seconds to display normal operation.
CAUTION: Your smoke/CO alarm is sealed and the cover is
NOT removable!
Battery Door Closed Battery Door Open

Battery Replacement
If any form of battery failure is detected the red LED will flash and
the unit will “chirp” one time, followed by the warning message
“Low battery”. This cycle will occur once every minute for the
first hour. After the first hour, the red LED will continue flashing
accompanied by the chirp sound every 60 seconds. The voice
message “Low battery” will sound once every 15 minutes during
the chirp-only cycle, and will continue for at least seven days.
If the red LED flashes along with a chirp every 30 seconds, and is not
followed by the voice message “Low battery” as described above,
your unit has malfunctioned. Call our toll free consumer hotline at
1-800-880-6788 for instructions on how to return the unit.
Replace batteries with alkaline Energizer E91. 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 smoke/CO alarm.
A good safety measure is to replace the batteries twice a year,
at the same time you change your clocks for daylight saving
time and for standard time. Constant exposure to high or low
temperatures or high humidity may reduce battery life.
NOTE: Do not use Lithium batteries with this unit.
Where to Mount the Alarm
IMPORTANT: THIS ALARM MUST BE MOUNTED ON A CEILING
OR WALL. IT WAS NOT DESIGNED FOR USE AS A TABLETOP
DEVICE. INSTALL ONLY AS DETAILED!
For maximum protection, Kidde recommends the installation of
a smoke/CO alarm in the following locations: on each level of a
multilevel home, including every bedroom, hallway, finished attic
and basement. Put alarms at both ends of bedroom, hallway or
large room if hallway or room is more than 9.1 m (30') long. If you
have only one alarm, ensure it is placed in the hallway outside of
the main sleeping area or in the main bedroom. Verify the alarm can
be heard in all sleeping areas.
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.

18
Smoke, heat and combustion particles rise to the ceiling and spread
horizontally. Mounting the 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. When mounting an
alarm on the ceiling, locate it at a minimum of 4" (10.2 cm) from
the side wall (see Image 2A).
If installing the alarm on the wall, use an inside wall with the top
edge of the alarm at a minimum of 4" (10.2 cm) and a maximum of
12" (30.5 cm) below the ceiling (see Image 2A).
Sloped Ceiling Installation
The following information is from the National Fire Protection
Association and is listed in Standard 72. Install smoke alarms on
sloped, peaked or cathedral ceilings at, or within 0.9 m (3’) of
the highest point (measured horizontally) (see Diagram A). NFPA
72 states “Smoke alarms in rooms with ceiling slopes greater than
0.3 m to 2.4 m (1' to 8') horizontally shall be located on the high
side of the room.” NFPA 72 also states “A row of alarms shall be
spaced and located within 0.9 m (3') of the peak of the ceiling
measured horizontally” (see Image 2B and 2C).
Mobile Homes
Modern mobile homes have been designed and built to be energy
efficient. In older mobile homes that are not well insulated, extreme
heat or cold can be transferred from the outside to the inside
through poorly insulated walls and roofs. This may cause a thermal
barrier, which can prevent smoke from reaching an alarm mounted
on the ceiling.
In such mobile homes install your smoke/CO alarm on an inside wall
with the top edge of the alarm at a minimum of 10 cm (4") and a
maximum of 30.5 cm (12") below the ceiling (see Diagram 2D). 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, install
your alarm on an inside wall ONLY!
THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH
THE NATIONAL FIRE PROTECTION ASSOCIATION’S STANDARD
72 (National Fire Protection Association, Batterymarch Park, Quincy,
MA 02269).
