1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the bedrooms.
Try to monitor the exit path as the bedrooms are usually farthest
from the exit. If more than one sleeping area exists, locate additional alarms in each sleeping area.
• Locate additional alarms to monitor any stairway as stairways act
like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances are
operated (i.e. portable heaters or humidifiers).
• 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 smoke 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).
• When mounting 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).
• Put smoke alarms at both ends of a bedroom hallway or large
room if the hallway or room is more than 30 ft (9.1 m) long.
• 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 ft in 8 ft (.3m in 2.4m) 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 (0.9m) of the
peak of the ceiling measured horizontally” (see figure 3).
2. LOCATIONS TO AVOID
In general alarms should not be located:
• In the garage. Products of combustion are present when you
start your automobile.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40ºF or rise
above 100ºF, such as garages and unfinished attics.
• In dusty areas. Dust particles may cause nuisance alarm or fail-
ure to alarm.
FIGURE 1
FIGURE 2 FIGURE 3
• In very humid areas. Moisture or steam can cause nuisance
alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (.9m) of the
following: the door to a kitchen, the door to a bathroom containing a tub or shower, forced air supply ducts used for heating
or cooling, ceiling or whole house ventilating fans, or other high
air flow areas.
• Kitchens. Normal cooking may cause nuisance alarms. If a
kitchen alarm is desired, it should have an alarm silence feature.
• Near fluorescent lights. Electronic “noise” may cause nuisance
alarms.
• Smoke alarms are not to be used with detector guards unless
the combination (alarm and guard) has been evaluated and
found suitable for that purpose.
• Battery powered smoke alarms are not designed to be installed
over an electrical box or opening and must not be installed in
this manner.
3. INSTALLATION INSTRUCTIONS

alarm on the mounting plate with the alignment marks lined up.
Twist the alarm in the direction indicated by the “ON” arrow on
the alarm cover (see figure 7) until it locks in place.
6. TAMPER RESIST FEATURE:
ACTIVATING THE TAMPER RESIST FEATURE
To make your smoke alarm tamper
resistant, a tamper resist means has
been provided. To activate this feature
you must break out the tamper resist
blocks. Use a small screwdriver to
break out these blocks on the alarm
(See figure 8).
Note: 29HIJ has only one tamper resist
block.
FIGURE 8
Break
out
Using this feature will help deter children and others from
removing the alarm from the mounting plate. With the blocks
removed the tamper resist feature will be activated when the
alarm is installed on the mounting plate.
7.REMOVING ALARM WITH TAMPER RESIST FEATURE ACTIVE
The tamper resist tab will have to be
released in order to change the battery. Using a tool (small screwdriver)
pull the tamper resist tab away from
the mounting plate (See figure 9).
With the tamper resist tab held away
from the alarm and rotate the alarm
in the off direction.
8.After installation, test your alarm by
depressing and holding down the test
button for several seconds, this should sound the alarm.
INTERCONNECTING ALARMS. (MODEL 29HIJ ONLY)
This model is equipped with interconnect capability. When alarms
are interconnected in a multiple station arrangement they must
not exceed the NFPA interconnect limit of 12 smoke alarms.
CAUTION! Do not interconnect with AC smoke alarms and
do not connect to AC power. Doing so will damage the
alarm and present a shock hazard.
The total length of wire that can be used in the interconnect system is 650 ft (200 Meters). The interconnect wires should not be
routed near fluorescent or discharge type lighting fixtures. Total
Wire Diameter (including insulation) should be between 1.5 mm
and 2.4mm, with a Conductor Diameter not less than 0.9mm.
Wire access slots are provided on both sides of the alarm mounting plate. Use pliers to breakout the desired access slot (see figure
10). Once the breakout has been removed, the wires can be routed to the screw connection (See figure 11). Be sure to observe the
wire polarity and connect all interconnected alarms utilizing the
correct polarity. It is possible to have more than one wire connected to each screw (see figure 12).
FIGURE 9
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once a fresh battery is
installed and testing is complete. When products of combustion
are sensed, the unit sounds a loud 85db pulsating alarm until the
air is cleared.
INTELLIGENT HUSHTMCONTROL
Note: The model 29J does not have Hush
®
The “HUSH®” feature has the capability of temporarily desensitizing the alarm circuit for up to 8 minutes. This feature is to be used
only when a known alarm condition, such as smoke from cooking,
activates the alarm. The smoke alarm is desensitized by pushing
the “HUSH®” button on the smoke alarm cover. If the smoke is
not too dense, the alarm will silence immediately and the red LED
will flash every 1.5 seconds while in Hush®. This indicates that the
alarm is in a temporarily desensitized condition. The smoke alarm
will automatically reset after 8 minutes and sound the alarm if particles of combustion are still present.
The “HUSH
®
” feature can be used repeatedly until the air has
been cleared of the condition causing the alarm. Pushing the
test/reset button on the alarm will end the Hush®period.

ALARM 1 ALARM 12
FIGURE 11
NOTE: DENSE SMOKE WILL OVERRIDE THE “HUSH®” CONTROL FEATURE AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM “HUSH®” FEATURE,
IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A
SAFE CONDITION EXISTS.
FLASHING LED LIGHT: This smoke alarm is equipped with a flashing Red indicator light with three modes of operation:
Normal Operation
The LED flashing every 40 - 45 seconds indicates that the smoke
alarm battery is properly installed and the alarm is operating.
Alarm Mode / Originating Unit Indicator
The LED will Flash about every second when the alarm is sounding
(constant pulsating sound) as a result of the test button being activated or the smoke sensing chamber senses particles of combustion.
WHEN UNITS ARE INTERCONNECTED, Model 29HIJ only, the red
LED of the alarm that senses the smoke or is being tested (the
originating unit) will flash rapidly. All other units in the interconnect system will sound an alarm but their red LED's will NOT flash
rapidly.
Hush® Mode.
The LED will Flash approximately every 1.5 seconds indicating the
alarm is in the "Hush®" mode.
SMOKE SENSING CHAMBER OPERATION: This alarm will "chirp" if
any of the components in the smoke-sensing chamber fail. This
chirp will occur between the normal standby flashes of the red
LED indicator light. (If the chirp occurs at the same time as the red
LED flash, this indicates a low battery, see section 6 for low battery
information.
ALARM MEMORY
This unit features an alarm memory to inform you that the alarm
has sounded since the test button was last pressed. If the alarm
memory is set the red LED will flash rapidly when the test button is
pressed. The alarm memory is reset when the test button is
released.
TESTING:
NOTE: WEEKLY TESTING IS REQUIRED!
CAUTION: Due to the loudness (85 decibels) of the alarm, always
stand an arms length away from the unit when testing.
Test by pushing the test button on the cover and holding it down
for a minimum of 5 seconds (or until the unit sounds). This will
sound the alarm if the electronic circuitry, horn, and battery are
working. If no alarm sounds, the unit has defective batteries or
other failure. DO NOT USE AN OPEN FLAME to test your alarm,
you could damage the alarm or ignite combustible materials and
start a fire.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic
or low sound coming from your alarm may indicate a defective
alarm, and it should be returned for service (see section 11).
NOTE: WEEKLY TESTING IS REQUIRED.
5. NUISANCE ALARMS
Smoke alarms are designed to minimize nuisance 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 the alarm is located 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.
If the alarm does sound, check for fires first. If a fire is discovered,
get out and call the fire department. If no fire is present, check to
see if one of the reasons listed in section 2 may have caused the
alarm.
6. MAINTENANCE
BATTERY REPLACEMENT
If tamper resist feature has been used, refer to “REMOVING
ALARM WITH TAMPER RESIST FEATURE ACTIVE” in section 3 for
removal instructions.
To replace the battery, remove the alarm from the mounting plate
by rotating the alarm in the direction of the “OFF” arrow on the
cover (see section 3, figure 7).
This Smoke Alarm is powered by 9 volt battery (carbon Zinc, alkaline, and Lithium batteries may be used). A fresh battery should
last for one year under normal operating conditions. Alkaline and
Lithium batteries will last longer than carbon Zinc batteries. This
alarm has a low battery monitor circuit which will cause the alarm
to “chirp” approximately every 30 - 40 seconds for a minimum of
seven (7) days when the battery gets low. Replace the battery
when this condition occurs. These batteries are available at many
local retail stores.
USE ONLY THE FOLLOWING 9 VOLT BATTERIES FOR SMOKE
ALARM REPLACEMENT.
Carbon Zinc Type: EVEREADY 1222; GOLD PEAK 1604S
Alkaline Type: ENERGIZER 522; DURACELL MN1604,
MX1604, GOLD PEAK 1604A; PANASONIC
6AM6, 6AM-6, 6AM-6PI, 6AM6X,
and 6LR61(GA)
Lithium Type: ULTRALIFE U9VL-J
NOTE: WEEKLY TESTING IS REQUIRED.
WARNING!! USE ONLY THE BATTERIES SPECIFIED. USE OF
DIFFERENT BATTERIES MAY HAVE A DETRIMENTAL EFFECT
ON THE SMOKE ALARM.
CLEANING YOUR ALARM
YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR
To clean your alarm, remove it from the mounting bracket as outlined in the beginning of this section (If tamper resist feature has
been used, refer to “REMOVING ALARM WITH TAMPER RESIST
FEATURE ACTIVE” in section 3 for removal instructions).
You can clean the interior of your alarm (sensing chamber) by
using compressed air or a vacuum cleaner hose and blowing or
vacuuming through the openings around the perimeter of the
alarm. The outside of the alarm can be wiped with a damp cloth.
After cleaning, reinstall your alarm and test your alarm by using
the test button. If cleaning does not restore the alarm to normal
operation the alarm should be replaced.
Do not paint your alarm. Paint will seal the vents and interfere
with the alarms ability to detect smoke and produce sound. Never
attempt to dismantle the alarm or clean the inside, as this will void
the warranty.
7. FIRE SAFETY
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• Photoelectric sensing alarms may detect visible fire parti-
cles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner
than Photoelectric alarms. Home fires develop in different
ways and are often unpredictable. For maximum protection, Kidde recommends that both Ionization and
Photoelectric alarms be installed.
• 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.
• Abatterypoweredalarmmust haveabattery ofthespecified type,
ingoodcondition andinstalledproperly.
• 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.
• 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.
8. GOOD SAFETY HABITS
DEVELOP AND PRACTICE A PLAN OF ESCAPE
• Make a floor plan indicating all doors and windows and at least
two (2) escape routes from each room. Second story windows
may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing
everyone what to do in case of fire.
• Determine a place outside your home where you all can meet if a
fire occurs.
• Familiarize everyone with the sound of the smoke alarm and train
them to leave your home when they hear it.
• Practice a fire drill at least every six months, including fire drills at
night. Ensure that small children hear the alarm and wake when
it sounds. They must wake up in order to execute the escape
plan. Practice allows all occupants to test your plan before an
emergency. You may not be able to reach your children. It is
important they know what to do.
• Install and maintain fire extinguishers on every level of the home
and in the kitchen, basement and garage. Know how to use a
fire extinguisher prior to an emergency.
• Current studies have shown smoke alarms may not awaken all
sleeping individuals, and that it is the responsibility of individuals
in the household that are capable of assisting others to provide
assistance to those who may not be awakened by the alarm
sound, or to those who may be incapable of safely evacuating
the area unassisted.
WHAT TO DO WHEN THE ALARM SOUNDS
• Alert small children in the home.
• Leave immediately by your escape plan. Every second counts, so
don’t waste time getting dressed or picking up valuables.
• In leaving, don’t open any inside door without first feeling its sur-
face. If hot, or if you see smoke seeping through cracks, don’t
open that door! Instead, use your alternate exit. If the inside of
the door is cool, place your shoulder against it, open it slightly
and be ready to slam it shut if heat and smoke rush in.
• Stay close to the floor if the air is smoky. Breathe shallowly through
a cloth, wet if possible.
• Once outside, go to your selected meeting place and make sure
everyone is there.
• Call the fire department from your neighbor’s home - not from
yours!
• Don’t return to your home until the fire officials say that it is all
right to do so.
There are situations where a smoke alarm may not be effective to
protect against fire as stated in the NFPA Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
9. NFPA REQUIRED PROTECTION
The National Fire Protection Association’s Standard 72 provides the
following information:
Smoke Detection - Where required by applicable laws, codes, or
standards for the specified occupancy, approved single- and multiple-station smoke alarms shall be installed as follows: (1) In all
sleeping rooms Exception: Smoke alarms shall not be required in
sleeping rooms in existing one- and two-family dwelling units. (2)
Outside of each separate sleeping area, in immediate vicinity of
the sleeping rooms. (3) On each level of the dwelling unit, including basements Exception: In existing one- and two-family dwelling
units, approved smoke alarms powered by batteries are permitted.
Smoke Detection - Are More Smoke Alarms Desirable? The
required number of smoke alarms might not provide reliable early
warning protection for those areas separated by a door from the
areas protected by the required smoke alarms. For this reason, it is
recommended that the householder consider the use of additional
smoke alarms for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not protected by the
required smoke alarms. The installation of the smoke alarms in
the kitchen, attic (finished or unfinished), or garage is normally not
recommended, as these locations occasionally experience conditions that can result in improper operation.
This equipment should be installed in accordance with the
National Fire Protection Association’s Standard 72 (NFPA,
Batterymarch Park, Quincy, MA 02269).
NOTIFY YOUR LOCAL FIRE DEPAR TMENT AND INSURANCE COMPANY OF YOUR SMOKE ALARM INSTALLATION.
10. CAUTION
“Early warning fire detection is best achieved by the installation of
fire detection equipment in all rooms and areas of the household
as follows: A smoke alarm installed in each separate sleeping area
(in the vicinity of, but outside of the bedrooms), and heat or
smoke detectors in the living rooms, dining rooms, bedrooms,
kitchens, hallways, attics, furnace rooms, closets, utility and storage rooms, basements and attached garages”.
