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.

NRC safety criteria in 10 CFR 32.27. The purchaser is exempt from any
regulatory requirements. Do not try to repair the smoke alarm yourself.
Refer to the instructions in Warranty section for service.
WARNING: Removal of the smoke alarm battery and
disconnecting or loss of AC power will render the smoke alarm
inoperative.
ELECTRICAL RATING: 120 V AC, 60 HZ, 80 mA maximum per alarm
(maximum 80 mA for originating unit with 24 devices interconnected).

2. Installation
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 Sleeping Room.
• 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 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.

2. Installation
• Install smoke alarms on sloped, peaked or cathedral ceilings
following the mounting guidelines outlined in image 2B and 2C.
Smoke alarms in rooms with ceiling slopes greater than 0.3 m in
2.4 m (1 foot in 8 feet) horizontally shall be located on the high
side of the room (Image 2B and 2C).

2. Installation
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 (Image 2D).
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. In this area install as
shown in images 2B and 2C.
• 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 affect 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 and
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 an alarm silence 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
CAUTION! Turn off the main power to the circuit before wiring
the alarm.
• 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.
• 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.
2. Installation

2. Installation
• 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.
IMPORTANT: Kidde alarms 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.
• For more information about compatible interconnect units and
their functionality in an interconnect system, visit our web site at:
www.kiddecanada.com
• 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.
