Introduction

Thank you for purchasing the Kidde Combination Smoke
and Carbon Monoxide Alarm model KN-COSMXTR-B. 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. 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 toll free Consumer
Hotline at 1-800-880-6788. The guide on page 26 will help

Features

• Permanent independent smoke and carbon monoxide

sensors.

Smoke alarm takes precedence when both smoke

•

and carbon monoxide are present.

• 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 followed by the verbal warning message
“FIRE! FIRE!”. This pattern 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
MONOXIDE!”. After four minutes the alarm/voice
pattern will sound once every minute until the
unit is reset, or the CO eliminated. The red 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”. 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” 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.

• 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.

–

carbon monoxide is detected the red LED light will
flash and the corresponding alarm pattern

problem.

Smoke Alarm Features

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.

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 warn

ing 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 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.

• 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.

Carbon Monoxide Alarm Features

• 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 insurance 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
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 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.

•

The battery polarity markings
on the bottom of the battery
compartment must be adhered to.

• Batteries must be installed in the

sequence shown. If the batteries
seem difficult to install, they’re
not being installed in the proper
sequence.

• Smoke/CO Alarm will not engage to bracket unless

all three batteries are installed. Removal of any or all
batteries will render the Smoke/CO Alarm inoperative!

• After the batteries are correctly installed the unit

will beep once and the red LED light will flash. After
20-30 seconds the green LED light will flash indicating
the unit is now operational.

CAUTION: Your Smoke/CO Alarm is sealed and the
cover is NOT removable!
