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!”

• 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!”

Important Warning Statements
IMPORTANT: Read all instructions before installation and keep this
User Guide near the alarm for future reference.
Do not try to repair the smoke alarm yourself. Refer to the
instructions in Warranty section for service.
WARNING: Removal of the alarm batteries will render the
alarm inoperative. This alarm requires a continuous supply of
electrical power – it will not work without power.
CAUTION: This alarm will only indicate the presence of
carbon monoxide at the sensor. Carbon monoxide may be
present in other areas.
WARNING: This product is intended for use in ordinary
indoor locations of family living units. It is not designed to
measure compliance with commercial or industrial standards.
It is not suitable for installation in hazardous locations as
defined in your local building code.
The installation of this device should not be used as a substitute for
proper installation, use and maintenance of fuel burning appliances,
including appropriate ventilation and exhaust systems. It does not
prevent CO from occurring, nor can it solve an existing CO problem.
WARNING: This device is designed to protect individuals
from acute effects of carbon monoxide exposure. It may not
fully safeguard individuals with specific medical conditions. If
in doubt, consult a medical practitioner.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon monoxide
concentrations under 30 PPM. This alarm has not been investigated
for carbon monoxide detection below 70 PPM.

Kidde 2-in-1 Smoke and Carbon Monoxide Alarms connect to each
other wirelessly to create the first Smart Wireless Network for fire
safety. When one of your Kidde Smart Wireless alarms is triggered,
a wireless signal will be transmitted to activate the rest of your
Kidde Smart Wireless alarms within 11 seconds, alerting you if you
are in other parts of the home. All other Smart Wireless alarms will
activate and remain in alarm mode until the initiating unit is silenced
or a non-initiating unit is silenced via a press of that unit’s button.
Place Kidde alarms throughout your home for comprehensive
coverage, so that you will be alerted to any smoke or CO danger no
matter where you are in your home.
For instructions on how to set up your Kidde alarms
so that they communicate wirelessly, see the Installation Guide
section.
This alarm wirelessly interconnects with the following Kidde
product:
• Kidde 2-in-1 Smoke and Carbon Monoxide Alarm
(Model KN-COSM-B-RF-CA)
The Kidde Smart Wireless Network may be expanded with future
Kidde products.

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.
