SMOKE ALARM
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.

purchaser is exempt from any regulatory requirements. Do
not try to repair the smoke alarm yourself. Refer to the
instructions in Warranty for service.
ELECTRICAL RATING: 120 V AC, 60 HZ, 80 mA maximum
per alarm (maximum 80 mA for originating unit with 24
devices interconnected).
WARNING! Battery door will not close unless battery is present.
Removal of the smoke alarm battery and disconnecting or loss of
A.C power will render the smoke alarm inoperative.
IMPORTANT! Read all instructions before installation and keep
this manual near the alarm for future reference.

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.
