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.

Recommended Locations
• 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 (Image 1A).
• 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 (Image 1B).
• 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 centre 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 10 cm (4") from the side wall (Image 2A).
• When mounting the alarm on the wall, use an inside
wall with the top edge of the alarm at a minimum of 10
cm (4") and a maximum of 30.5 cm (12") below the
ceiling (Image 2A).
• Put smoke alarms at both ends of a bedroom hallway
or large room if the hallway or room is more than 9.1 m
(30') long.
• For mobile home installation, select locations carefully
to avoid thermal barriers that may form at the ceiling.
For more details, see Mobile Homes.

Installation

• Install smoke alarms on sloped, peaked or cathedral
ceilings at or within 0.9 m (3') of the highest point
(measured horizontally). NFPA Standard 72 states: “Smoke
alarms in rooms with ceiling slopes greater than 0.3 m in
2.4 m (1' in 8') horizontally shall be located on the high
side of the room.” NFPA Standard 72 states: “A row of
detectors shall be spaced and located within 0.9 m (3') of
the peak of the ceiling measured horizontally” (Image 2B
and Image 2C).

Locations to Avoid
• Do not install within 0.9 m (3') of the following: The
door to a kitchen, or a bathroom that contains 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.
• Do not place the alarm where drapes or other objects
will block the sensor. Smoke must be able to reach the
sensor to accurately detect conditions.
• Do not install in peaks of vaulted ceilings, “A” frame
ceilings or gabled roofs. (Less than 10 cm (4") from the
peak of an “A” frame type ceiling.)
• Install at least 30.5 cm (12") away from fluorescent
lights as electronic noise may cause nuisance alarms.
• Keep out of insect infested areas. Avoid excessively
dusty, dirty or greasy areas. Dust particles may cause
nuisance alarms or failure to alarm.
• Extreme temperatures may effect the sensitivity of the
alarm. Do not install in areas where the temperature is
colder than 4.4°C (40°F) or hotter than 37.8°C (100°F),
such as garages or unfinished attics.
• Do not install in areas where the relative humidity (RH)
is greater than 85%. Very humid areas, with moisture or
steam, can cause nuisance alarms.
• Avoid placing ionization smoke alarms in kitchen areas.
Normal cooking may cause nuisance alarms. If a
kitchen alarm is desired, it should have Hush®control
feature or be a photoelectric type.
• Do not place in the garage. Particles of combustion are
present when you start your automobile.
• 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.

Mobile Homes
Modern mobile homes have been designed to be energy efficient.
Install smoke alarms as recommended in Recommended Locations and
Image 2A.
In older mobile homes that are not well-insulated compared to
present standards, extreme heat or cold can be transferred from the
outside to the inside through poorly insulated walls and roof. This
may create a thermal barrier that can prevent the smoke from
reaching an alarm mounted on the ceiling. In such units, install the
smoke alarm on an inside wall with the top edge of the alarm at a
minimum of 10 cm (4") and a maximum of 30.5 cm (12") below the
ceiling (Image 2A).
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 the alarm on an inside wall. For minimum protection, install at
least one alarm close to the bedrooms. For additional protection, see
Image 1A.
WARNING: Test your smoke alarm operation after R.V. or mobile home vehicle
has been in storage, before each trip and at least once a week during use.
Wiring Requirements
• This smoke alarm should be installed on a CSA listed or recognized
junction box. All connections should be made by a qualified
electrician and all wiring used shall be in accordance with articles
210 and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA
70, NFPA 72 and/or any other codes having jurisdiction in your
area. The multiple station interconnect wiring must be run in the
same raceway or cable as the AC power wiring to the alarms. In
addition, the resistance of the interconnect wiring shall be a
maximum of 10 ohms.
• The appropriate power source is 120 Volt AC Single Phase supplied
from a non-switchable circuit which is not protected by a ground
fault interrupter.
• WARNING: The alarm should not be operated on power derived
from a square wave, modified square wave or modified sine wave
inverter. These power sources produce high peak voltages that will
damage the alarm. These types of inverters are sometimes used to
supply power to the structure in off grid installations, such as solar
or wind derived power sources.

Wiring Instructions
CAUTION! Turn off the main power to the circuit before wiring
the alarm.
• For alarms that are used as single station, DO NOT CONNECT
THE RED WIRE TO ANYTHING. Leave the red wire insulating
cap in place to make certain that the red wire cannot contact
any metal parts or the electrical box.
• When alarms are interconnected, all interconnected units must
be powered from a single circuit.
• A maximum of 24 Kidde devices may be interconnected in a
multiple station arrangement. The interconnect system should
not exceed the NFPA interconnect limit of 12 smoke alarms
and/or 18 alarms total (smoke, heat, carbon monoxide, etc.)
With 18 alarms interconnected, it is still possible to interconnect
up to a total of 6 remote signaling devices and/or relay modules.
CAUTION! Kidde alarm and accessories CAN ONLY BE
interconnected with other Kidde alarms and accessories as well
as specified brands and models of interconnect compatible alarms.
Connection of Kidde products to a non-specified manufacturer’s
interconnect system, or connection with non-specified equipment
from another manufacturer into an existing Kidde system could
result in nuisance alarming, failure to alarm, or damage to one
or all of the devices in the interconnect system. Refer to the
User’s Guide supplied with each Kidde product for interconnect
compatible models, brands, and devices.
• When mixing models which have battery backup with models
without battery backup, be advised that the models without
battery backup will not respond during an AC power failure.
• The maximum wire run distance between the first and last
unit in an interconnected system is 305 m (1000').
• Image 3 illustrates interconnection wiring. Improper connection
will result in damage to the alarm, failure to operate, or a
shock hazard.
• Make certain alarms are wired to a continuous (non-switched)
power line. NOTE: Use standard CSA listed household wire
(as required by local codes) available at all electrical supply
stores and most hardware stores.

Hush®Control Feature
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 that vents to the
outside (non-recirculating type) will also help remove
these combustible particles from the kitchen. The Hush®
button is extremely useful in a kitchen area or other areas
prone to nuisance alarms.
The Hush®feature has the capability of temporarily
desensitizing the smoke alarm circuit for about 8 minutes.
This feature is to be used only when a known alarm
condition, such as smoke from cooking, activates the alarm.
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
Locations to Avoid may have caused 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 2 seconds for approximately 8 minutes. This
indicates that the alarm is in a temporarily desensitized
condition. The smoke alarm will automatically reset after
approximately 8 minutes. If after this period particles of
combustion are still present, the alarm will sound again.
The Hush®feature can be used repeatedly until the air has
been cleared of the condition causing the alarm. Pushing
the Test button on the alarm will end the alarm silencing
period.
NOTE: Dense smoke will override the Hush®feature and sound a
continuous alarm.
CAUTION: Before using the Hush®feature, identify the source of
the smoke and be certain a safe condition exists.

LED Indicators
This smoke alarm is equipped with red and green LED
indicators. The red LED is located under the test button and
has several modes of operation. The green LED is located
under the Hush®button and indicates the presence of AC
power.
Standby Condition The red LED will flash every 30–40
seconds to indicate that the smoke
alarm is operating properly. The green
LED will be lit, indicating the presence
of AC power.
Alarm Condition When the alarm senses particles of
combustion and goes into alarm, the
red LED will flash rapidly (once every
two seconds). The rapid flashing LED
and temporal alarm will continue
until the air is cleared.
Hush Condition The red LED will flash every 2 seconds
as long as the alarm is in Hush®mode.
Low Battery Condition The red LED flash will be accompanied
by an audible chirp. Replace the
battery when this condition occurs.
Alarm Memory This smoke alarm is equipped with
an alarm memory which provides a
visual indication when an alarm has
been activated. A lit red LED
indicates the memory condition. The
memory will remain activated until it
is reset by pushing the test button.
Smoke Sensing Chamber Operation
The alarm will “chirp” if any of the components in the smoke
sensing chamber fail. This chirp will occur between the
flashes of the red LED indicator light. If the “chirp” occurs at
the same time as the red LED flash, see Battery Replacement
section for more information.
Operation

When Units Are Interconnected
Only the red LED of the alarm “which 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.
Testing
Test by pushing the Test button on the cover and hold
it down for a minimum of 5 seconds. This will sound
the alarm if all the electronic circuitry, horn and battery
are working. In an interconnected installation all
interconnected alarms should sound when the test button
on any one of the interconnected alarms is pressed. 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 structure fire.
Alarm Memory
This smoke alarm is equipped with an alarm memory
feature which produces a visual indication when an alarm
has been activated. A lit red LED indicates the memory
condition. The memory will remain activated until it is
reset by pushing the test button.
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 to place of
purchase (see Warranty section).
NOTE: WEEKLY TESTING IS REQUIRED!

Alarm Removal
If the smoke alarm tamper resist feature has been activated, refer
to the alarm tamper-resist feature section for removal instructions.
To remove the alarm from the mounting plate, rotate the alarm
in the direction of the “OFF” arrow on the cover. To
disconnect the AC power harness, squeeze the locking arms
on the sides of the Quick Connector while pulling the
connector away from the bottom of the alarm.
Battery Replacement
To replace or install the batteries you must first remove the
alarm from the mounting plate by following the ALARM
REMOVAL instructions at the beginning of this section. After the
alarm has been removed, you can open the battery door and
install or replace the battery. Battery installation instructions are
provided on the inside of the battery door.
This smoke alarm uses a 9 V alkaline battery (a lithium battery
may also be used). A fresh alkaline battery should last for one
year under normal operating conditions. This alarm has a low
battery monitor circuit which will cause the alarm to “chirp”
approximately every 30 seconds for a minimum of 7 days when
the battery loses power. Replace when this condition occurs.
Use only the following 9 V batteries for replacement:
Alkaline Type Energizer 522
Duracell MN1604 or MX1604
Gold Peak 1604A
Panasonic 6AM6, 6AM-6, 6AM-6PI,
6AM6X, and 6LR61(GA)
Lithium Type Ultralife U9VL-J
After installing or changing the battery, reinstall your alarm.Test
your alarm by using the test button and check that the green
LED is on.

18
Maintenance
WARNING! Use only the batteries specified. Use of different batteries
than the recommended ones, may have a detrimental effect on the
smoke alarm. A good safety measure is to replace the battery at least
once a year, or at the same time you change your clocks for daylight
saving time. Be sure to follow the battery installation instructions
printed on the back of the alarm.
NOTE: WEEKLY TESTING IS REQUIRED!
NOTE: If after battery replacement the alarm continues to chirp,
push the Test button. The Hush®feature may have been
activated accidently while changing the battery and pushing the
Test button will end the Hush®cycle.
Cleaning the Alarm
The alarm should be cleaned at least once a year.
• To clean your alarm, remove it from the mounting plate as
outlined in previous sections. You can clean the alarm by
using compressed air or a vacuum cleaner hose with a soft
brush attachment. Blow or vacuum around the perimeter of
the alarm to remove dust and dirt. The outside of the alarm
can be wiped with a damp cloth (do not use a wet cloth to
avoid water entering the unit).
• 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 the unit. Paint will seal the vents and interfere
with the sensor’s ability to detect smoke. Never attempt to
disassemble the unit or clean inside. This action will void
your warranty.
Replacing the Alarm
The National Fire Protection Association (NFPA) recommend
replacing this alarm ten years from the date code label (located
on the back of the alarm).

19
Fire Safety
Limitations of Smoke Alarms
WARNING: Please read carefully and thoroughly.
• 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, smouldering 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.
• 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.
