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.

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.

• 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).
Batteries Must Be Installed in Order Shown Below:

@ 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!

Step 2
Installation Instructions:
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, including every
bedroom, hallways, finished attics and basements. Put
alarms at both ends of bedroom, hallway or large room
if hallway or room is more than 30ft. (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 bed-
room. 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 the
alarm 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 residen-
tial construction. When mounting an alarm on the ceil-
ing, locate it at a minimum of 4” (10cm) from
the side wall (see Diagram A). 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” G0.5cm) below the ceiling (see Diagram A).

Operating/Installation Instructions
Sloped Ceiling Installation:
The following information is from the National Fire
Protection Association and is listed in Fire Code 72.
Install Smoke Alarms on sloped, peaked or cathedral
ceilings at, or within 3ft (0.9m) of the highest point
(measured horizontally). NFPA 72 states “Smoke
alarms in rooms with ceiling slopes greater than 1 foot
to 8 feet (.3 m-2.4 m) horizontally shall be located on
the high side of the room.”
NFPA 72 states “A row of alarms shall be spaced and
located within 3 ft (0.9 m) of the peak of the ceiling
measured horizontally.” (See Diagram B)

Mobile Homes:
Mobile homes built within the last five to seven years
are designed to be energy efficient. Install Smoke/CO
alarms as recommended above. (Refer to Recommended
Installation Instructions and Diagram A) In mobile
homes that are not well insulated, extreme heat or cold
can be transferred from the outside to the inside
through poorly insulated walls and roof. This may cause
a thermal barrier, which can prevent smoke from reach-
ing an alarm mounted on the ceiling. In such mobile
homes install your Smoke/CO Alarm on an inside wall
with the top edge of the alarm at a minimum of 4 inch-
es (10cm) and a maximum of 12 inches (30.5cm) below
the ceiling. (See Diagram A) If you are not sure about
the insulation in your mobile home, or if you notice that
the outer walls and ceiling are either hot or cold, install
your alarm on an inside wall ONLY!

flow areas. Avoid excessively dusty, dirty or greasy areas.
Dust, grease or household chemicals can contaminate
the alarm’s sensors, causing it to not operate properly.
Place the alarm where drapes or other objects will not
block the sensors. Smoke and CO must be able to reach
the sensors to accurately detect these conditions. Do
not install in peaks of vaulted ceilings, “А” frame ceilings
or gabled roofs. Keep out of damp and humid areas.
12

Operating/Installation Instructions
Install at least one (1) foot away from fluorescent lights,
electronic noise may cause nuisance alarms. Do not
place in direct sunlight and keep out of insect infested
areas. Extreme temperatures will effect the sensitivity
of the Smoke/CO Alarm. Do not install in areas where
the temperature is colder than 40 degrees Fahrenheit
(4.4 Celsius) or hotter than 100 degrees Fahrenheit
(37.8 Celsius). Place away from doors and windows
that open to the outside.
C. How to Install:
Remove mounting plate from the back of the unit by hold-
ing the rim of the mounting plate and twisting counter-
clockwise (left). Hold the mounting plate against the select-
ed installation location (wall or ceiling) and mark the cen-
ter of the holes with a pencil. To ensure aesthetic align-
ment of the alarm with the hallway, or wall, the “A” line on
the mounting plate must be parallel with the hallway when
ceiling mounting, or horizontal when wall mounting. Drill
a hole through the pencil marks and use the enclosed
screws and anchors to secure (use 3/16” drill bit for anchor
holes). Align the Smoke/CO Alarm with the mounting plate
and rotate clockwise (right) until the unit is aligned. Screw
and anchor accessories are supplied.

Step 3
Testing the Alarm
The test button has three purposes. It tests the unit’s
electronics, resets the alarm and activates the peak level
memory (See page 16).
CAUTION: Due to the loudness (85 decibels) of the
alarm, always stand an arms length away from the
unit when testing.
* To test: Press the test/reset button for five
seconds and a series of beeps will sound, followed
by the message “Fire! Fire!”, then another two series
of beeps and the message “Warning! Carbon
Monoxide”, followed by 4 additional short
beeps.
• Reset: If the the Smoke/CO Alarm is sounding a CO
alarm, pressing the test/reset button will silence the
alarm. If the CO condition that caused the alert con
tinues, the alarm will reactivate. Reactivation times
depend on the amount of CO present. See page 19.
• Peak Level Memory: If 8 chirps are made when
pushing the test/reset button, the unit has detected
a CO level of 100 PPM or greater.
The unit needs to be tested weekly! If at anytime it
does not perform as described, verify the three batteries
are installed correctly and that they don’t need replacing.
Clean dust and other buildup off the unit. If it still doesn’t
operate properly call the Consumer Hotline at 1-800-880-
6788.

Peak Level Memory
If the CO sensor has detected a CO levei of 100 PPM or
higher since last reset, it will be recorded by the Peak
Level Memory function.To access the Peak Level
Memory press the test/reset button. If a reading of 100
PPM or higher has been recorded the unit will chirp 8 |
times. If you've been away from home this feature
allows you to check if there was a CO reading of 100, or
higher, during your absence. Pushing the test/reset
button resets the memory. It’s also reset when batteries
are removed.

What To Do If The Alarm Sounds
NEVER IGNORE THE SOUND OF THE ALARM!
Determining what type of alarm has sounded is easy
with your Nighthawk Combination Smoke/CO Alarm.
The voice message warning system will inform you of
the type of situation occurring. Refer to the Features
section on page 4 for a detailed description of each
alarm pattern.
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.
Combustion particles from cooking may set off the
alarm if located too close to the cooking area. Large
quantities of combustible particles are generated from
spills or when broiling. 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.

What То Do If The Alarm Sounds
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!
• Leave immediately using one of your planned
escape routes (see page 24). 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 give the go ahead.
17

What То Do If The Alarm Sounds
When the carbon monoxide alarm sounds:
WARNING: Actuation of your CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can KILL YOU.
If alarm signal sounds:
1)
Operate the test/reset button;
2) Call your emergency PHONE NUMBER
services (fire dept. or 911);
3) 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 reenter 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
con-
dition.
4) After following steps 1-3, if your alarm reactivates
18
within a 24 hour period, repeat steps 1-3 and call a
qualified appliance PHONE NUMBER
technician to
investigate for sources
of CO from fuel burning equipment and appliances,
and inspect for proper operation of this equipment.
If problems are identified during this inspection have
the equipment serviced immediately. Note any com-
bustion equipment not inspected by the technician
and consult the manufacturer’s instructions, ог con-
tact the manufacturer’s directly, for more informa-
tion about CO safety and this equipment. Make sure
that motor vehicles are not, and have not been, oper-
ating in an attached garage or adjacent to the resi-
dence.
