Thank you for purchasing the Kidde
Combination Smoke and Carbon Monoxide Alarm
Model # KN-COSM-BCA.
This alarm has a five-year limited warranty.
Please take a few minutes to thoroughly read this
user’s guide, and save for future reference. Teach
children how to respond to the alarms, and that they
should never play with the unit.
Your Kidde Smoke/CO Alarm was designed to detect
both smoke and carbon monoxide from any source of
combustion in a residential environment. t is not
designed for use in a recreational vehicle (RV) or boat.
f you have any questions about the operation or
installation of your alarm, please call our toll free
Consumer Hotline at 1-800-880-6788.

• Permanent independent smoke and carbon
monoxide sensors (ionization and electrochemical).
• Loud 85 decibel alarm.
• Alarm/Voice message warning system that specifies
which dangerous condition exists, eliminating any
confusion over which alarm is sounding:
FIRE: The alarm/voice pattern is 8 seconds of alarm
beeps followed by the verbal warning message,
“Fire! Feu!” This pattern is repeated until the smoke
is eliminated. The red LED light will flash while in
alarm/voice mode.
CARBO MO OXIDE: The alarm/voice pattern is four
short alarm beeps followed by the verbal warning
message, “Carbon Monoxide! Monoxyde de Carbone!”
This continues until the unit is reset or the CO
eliminated. After four minutes the alarm/voice
pattern will sound once every minute. The red
Light Emitting Diode (LED) light will flash while in
alarm/voice mode.
LOW BATTERY: When the batteries are low and need
replacing the red LED light 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 light will continue to flash
every minute accompanied by the "chirp" only
sound. The voice message “Low Battery. Pile
Faible!” 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. f this occurs call the
Consumer Hotline at 1-800-880-6788.
OTE: After seven (7) years of cumulative power up,
this unit will "chirp" twice every 30 seconds. This is
an "operational end of life" feature which will
indicate that it is time to replace the alarm.

• Oversized test button for easy activation.
• Test button performs the following functions:
Tests the units electronics and verifies
proper unit operation
Resets the unit during CO alarm
Activates HUSH® Feature (see Page 16).
Peak Level Memory (See Page 17).
• Mounting bracket designed for easy orientation
of unit.
• Green and red LED lights that indicate normal
operation and alarm status.
Green Light: The green Light Emitting Diode (LED)
flashes every 30 seconds to indicate the unit is
operating properly, and once every 2 seconds to
indicate the unit is in HUSH® mode. The green
light also flashes before a CO reading is taken and
when any button is pressed.
Red Light: When a dangerous level of smoke or
carbon monoxide is detected the red Light Emitting
Diode (LED) will flash and the corresponding alarm
pattern (depending on the source) will sound. f
the unit malfunctions, the red LED light will flash
and the unit will chirp every 30 seconds indicating a
system problem.
• Powered by three (3) AA batteries.
• Battery lockout system that prohibits installation
without using three batteries.
• Smoke alarm takes precedence when both smoke
and carbon monoxide are present.

Tamper Resist Feature
To make the Smoke/CO alarm tamper resistant, a
tamper resist feature has been provided. Activate the
tamper resist feature by breaking off the four posts in
the square holes in the mounting plate (see Figure 1A).
Rotate the alarm onto the mounting plate until you
hear the tamper resist tab snap into place, locking the
alarm.
Using the tamper resist feature will help deter children
and others from removing the alarm. To remove the
alarm, press on the tamper resist tab, and rotate the
alarm off of the mounting plate (see Figure 1B).

Smoke Alarm
The smoke alarm constantly monitors the air for
products of combustion that are produced when
something is burning or smoldering. When smoke
particles in the smoke sensor reach a specified
concentration, the alarm/voice message warning system
will sound, accompanied by the flashing red LED light.
OTE: The smoke alarm takes precedence when both
smoke and carbon monoxide are present.
This unit has a smoke sensor that uses the ionization
technology.
Smoke alarms are devices that can provide early warning of
possible fires at a reasonable cost, however, alarms have
sensing limitations.
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.
Home fires develop in different ways and are often
unpredictable. For maximum protection, Kidde recommends
both ionization and photoelectric smoke alarms be installed.
CAUTIO : Smoke must reach the sensor to be detected.
Smoke alarms may not sense fires starting in chimneys,
walls, on roofs, on the other side of a closed door, or on a
different floor. The alarm may be unable to wake a sound
sleeper, or someone impaired by alcohol or drugs.

Carbon Monoxide (CO) Alarm
The carbon monoxide (CO) alarm constantly monitors the air
for the presence of CO. t 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 (see Page 20 for alarm
times). When a CO condition matches either of these
situations, the alarm/voice message warning system will
sound, accompanied by the flashing red LED light.
The carbon monoxide sensor uses an electrochemical
technology.
CAUTIO : This alarm will only indicate the presence
of carbon monoxide gas at the sensor. Carbon monoxide
gas may be present in other areas.
This device is designed to protect individuals from the
acute effects of carbon monoxide exposure. t will not
fully safeguard individuals with specific medical
conditions. f in doubt consult a medical practitioner.
Installation of the device should not be used as a substitute for
proper installation, use, and maintenance of fuel-burning
appliances, including appropriate ventilation and exhaust
systems.
ndividuals with medical problems may consider using
warning devices which provide audible and visual
signals for carbon monoxide concentrations under
30 ppm.
ever ignore the sound of an alarm!
Determining what type of alarm has sounded is easy
with the Combination Smoke/CO Alarm.
The voice message warning system will inform you of
the type of hazard occurring.
