Thank you for purchasing the Nighthawk™
Combination Smoke and Carbon Monoxide Alarm
model # KN-COSM-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 Nighthawk
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 installa-
tion of your alarm, please call our toll free Consumer
Hotline at 1-800-880-6788. The guide on page 25 will

Features
• Permanent independent smoke and carbon
monoxide sensors.
* Smoke alarm takes precedence when both
fire 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 “WARNING! CARBON
MONOXIDE!”. After four minutes the alarm/voice
pattern will sound once every minute until the
unit is reset, or the CO eliminated. 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” 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.

Features
* 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.
• Loud 85 decibel 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
Peak Level Memory (See page 16).
• 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. 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. If 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.
• Tamper Resist Feature that deters children and
others from removing the alarm. 5

Smoke Alarm Features
Smoke Alarm
The smoke alarm monitors the air for products of com-
bustion that are produced when something is burning
or smoldering. When smoke particles in the smoke sen-
sor reach a specified concentration, the alarm/voice
message warning system will sound, and be accompa-
nied by the flashing red LED light. The smoke alarm
takes precedence when both smoke and carbon
monoxide are present.
This unit has a smoke sensor that uses the ioniza-
tion technology. Ionization units are the fastest at
responding to fast flaming fires that give off little
smoke. Photoelectric smoke alarms are the fastest at
responding to slow smoldering, smoky fires. Kidde
Safety recommends for maximum protection that
both ionization and photoelectric smoke alarms
should be installed. Home fires can develop in differ-
ent ways and are often unpredictable. Neither type of
alarm is always best, and a given alarm may not always
provide warning of a fire.
CAUTION: Smoke must reach the sensor to be detect-
ed. Smoke alarms may not sense fires starting in chim-
neys, 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 Alarm Features
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 pres-
ence 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 sig-
nals for carbon monoxide concentrations under 30 ppm.

Operating/Installation Instructions
Step 1
Installing Batteries:
Batteries were not installed at the factory and must
be installed for the unit to operate! Install the three (33
AA batteries in the back of the Smoke/CO Alarm.
• The mounting plate must be removed from the
back of the unit to install batteries.To remove, hold
the mounting plate and twist counterclockwise (left).

Ө Second п + AA Battery
@ Install
First
• The battery polarity markings on the bottom of the
battery compartment must be adhered to.
• Batteries must be installed in the sequence shown. If
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!
