• Loud 85 decibel alarm.
• Ionization smoke sensor.
• Powered by 120V AC (60 Hz, 45mA max) wire-in connector .
• Interconnectable to other Kidde/Nighthawk brand smoke and
CO alarms (see page 15 for details).
SMOKE ALARM: The alarm pattern is three long alarm beeps,
which will repeat until the smoke is eliminated. The red LED
light will flash with the alarm beeps..
LOW BATTERY: If the battery is low, the red LED light will flash
and the unit will “chirp” every 60 seconds, for a minimum of
seven (7) days. This alarm contains a sealed 3V Lithium battery,
which will last the life of the alarm. No need to replace
batteries.
• The End of Product Life Alarm/Signal is a double chirp and flash
every 30 seconds (see page 17).
• End of Life Hush. At end of product life, the button can be
pushed to silence the end of life "chirp" for approximately
3 days at a time, for a maximum of 30 days life extension.
• One “chirp” every 30 seconds coupled with a green LED flash
twice a second is an indication that the alarm is
malfunctioning. If this occurs call the Product Support Line at
1-800-880-6788.
• Test/Reset button performs functions.(See page 14).
• HUSH Control Feature that silences the unit during nuisance
alarm situations (see page 15).
• Alarm Memory Feature that gives visual indication when an
alarm has sensed a hazardous condition(see page 16).
• Green and red LED lights that indicate normal operation and
alarm status (see page 17 for details).
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 warning system will sound, and be
accompanied by the flashing red LED light.

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 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 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.
• Smoke alarms must be tested regularly to make sure the
batteries 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
insurance policy. Home owners and renters should have
adequate insurance to protect their lives and property.

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 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 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
combustion 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 ceiling,
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).

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 3 ft (0.9m) of the highest point (measured horizontally).
NFPA 72 states “Smoke alarms in rooms with ceiling slopes
greater than 1 ft to 8 ft (.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 figure 2).
Install Smoke Alarms on tray-shaped ceilings (coffered ceilings)
on the highest portion of the ceiling or on the sloped portion of
the ceiling within 30.5 cm (12”) vertically down from the highest
point (see figure 2).
Mobile Homes:
Modern mobile homes have been designed and built to be
energy efficient. Install Smoke alarms as recommended above
(refer to Recommended Installation Instructions and figure 1).
In older mobile homes that are not well insulated, extreme heat
or cold can be transferred from the outside to the inside
