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 combus-
tion in a residential environment. It is not designed for use in a
recreational vehicle (RV) or boat. If you have any questions
about the operation or installation of your alarm, please call our

• Loud 85 decibel alarm.
• Permanent independent smoke and carbon monoxide sensors.
•Smoke alarm takes precedence when both smoke and
carbon monoxide are present.
• Powered by 120V AC (60 Hz, 25 mA max) wire-in connector.
Model KN-COSM-IB is also equipped with a 9V battery back-
up.
• Model KN-COSM-IB is equipped with Battery Pull Tab that
allows for easy battery connection. Simply pull tab out, and
battery is connected!
• Interconnectable to other Kidde/Nighthawk brand smoke and
CO alarms (see page 16 for details).
• Alarm/Voice message warning system that alerts you of 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 fol-
lowed by the verbal warning message “FIRE! FIRE!” This pat-
tern is repeated until the smoke is eliminated. The red LED
light will flash while in alarm/voice mode.
CARBON MONOXIDE: The alarm/voice pattern is four short
alarm beeps followed by the verbal warning message
“WARNING! CARBON MONOXIDE!". This continues until the
unit is reset or the CO eliminated. While powered by battery
only, 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(model KN-COSM-IB only): When the bat-
teries 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.” This cycle will occur once every
minute and will continue for at least seven days.

• Voice Message System that alerts user to the following condi-
tions:
– System announces “HUSH MODE ACTIVATED” when
the unit is first put into HUSH Mode.
– System announces “HUSH MODE CANCELLED” when
unit resumes normal operation after Hush Mode has
been cancelled.
– System announces “CARBON MONOXIDE PREVIOUSLY
DETECTED” when the unit has detected CO
concentrations of 100 ppm or higher.
– System announces “PUSH TEST BUTTON” when the unit
is powered up, reminding user to activate the Test
Button.
• 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.
• Test/Reset button performs the following functions:
– Tests the units electronics and verifies proper unit
operation
– Resets the unit during CO alarm
– Activates HUSH Feature
– Activates Peak Level Memory Feature
• HUSH Control Feature that silences the unit during nuisance
alarm situations (see page 15).
• Peak Level Memory Feature which alerts user when the unit
has detected CO concentrations of 100 ppm or greater (see
page 16).
• Alarm Memory Feature that gives visual indication when an
alarm has sensed a hazardous condition.
•Green and red LED lights that indicate normal operation and
alarm status (see page 17 for details).
• Tamper Resist Feature that deters children and others from
removing the alarm (see page 17).
•Model KN-COSM-IB is equipped with a battery reminder flag
that prohibits installation when battery is not present.

• Seven (7) years after initial power up, this unit will “chirp”
every 30 seconds. This is an “operational end of life” feature
which will indicate that it is time to replace the alarm.
Smoke Alarm
The smoke alarm 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, and be accompanied by the flashing red LED light. The
smoke alarm takes precedence when both smoke and carbon
monoxide are present.
WARNING: PLEASE READ CAREFULLY AND
THOROUGHLY
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 possi-
ble. 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 sens-
ing 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 that both Ionization and Photoelectric
alarms be installed.
•A battery powered alarm must have a battery of the specified
type, in good condition and installed properly.
Features and General Information

• 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 bat-
teries 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, 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 insur-
ance policy. Home owners and renters should have adequate
insurance to protect their lives and property.
Carbon Monoxide (CO) Alarm
The Carbon Monoxide (CO) alarm monitors the air for the pres-
ence 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 (see page 21 for alarm times). 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 light. The carbon monoxide sensor uses an
electrochemical technology.
CAUTION: This alarm will only indicate the presence of
carbon monoxide gas at the sensor. Carbon monoxide
gas may be present in other areas.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm.

Step 1
Installation Guide:
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!
A. Recommended Installation Locations:
Kidde Safety recommends the installation of a Smoke/CO Alarm
in the following locations. For maximum protection we suggest
an alarm be installed on each level of a multilevel home, includ-
ing every bedroom, hallways, finished attics and basements. Put
alarms at both ends of bedroom, hallway or large room if hall-
way or room is more than 30 ft (9.1m) 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. Smoke, heat and com-
bustion products 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 ceil-
ing, locate it at a
minimum of 4”
(10cm) from the side
wall (see figure 1). If
installing the alarm
on the wall, use an
inside wall with the
top edge of the
alarm at a minimum
of 4” (10cm) and a
maximum of 12”
(30.5cm) below the
ceiling (see figure 1).
