moke Alarm
The smoke alarm constantly 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/voice message warning system
will sound, accompanied by the flashing red LED light.
NOTE: The smoke alarm takes precedence when both
smoke and carbon monoxide are present.
WARNING: LEASE READ CAREFULLYANDTHOROUGHLY
NFPA Standard 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. ome 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.
• 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.
Carbon Monoxide (CO) Alarm
The carbon monoxide (CO) alarm constantly monitors the
air for the presence of CO. It will alarm when there are
high levels of CO present, and when there are low levels
of CO present over a longer period of time. When a CO
condition matches either of these situations, the
alarm/voice message warning system will sound,
accompanied by the flashing red LED light.
The carbon monoxide sensor uses an electrochemical technology.
CAUTION: This alarm will only indicate the presence of
carbon monoxide gas at the sensor. Carbon monoxide gas
may be present in other areas.
This device is designed to protect individuals from the
acute effects of carbon monoxide exposure. It will not
fully safeguard individuals with specific medical
conditions. If in doubt, consult a medical practitioner.
Installation of the device should not be used as a
substitute for proper installation, use, and maintenance
of fuel-burning appliances, including appropriate
ventilation and exhaust systems.
Individuals with medical problems may consider using
warning devices which provide audible and visual signals
for carbon monoxide concentrations under 30 ppm.
Never ignore the sound of the alarm!
Determining what type of alarm has sounded is easy
with the Kidde Combination Smoke/CO Alarm. The
voice message warning system will inform you of the
type of hazard occurring.

Recommended Installation Locations
WARNING: This product is intended for use in
ordinary indoor locations of family living units.
It is not designed to measure compliance with
commercial or industrial standards.
IM ORTANT: This alarm must be mounted on a ceiling
or wall. It was not designed for use as a tabletop device.
Install only as directed.
Industry experts recommend the installation of a
Smoke/CO Alarm in the following locations. For
maximum protection they suggest an alarm be installed
on each level of a multilevel home, every bedroom,
hallways, finished attics and basements. Put alarms at
both ends of bedroom, hallway or large room if it is
more than 9.1 m (30’) 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 10 cm (4") from the side wall
(see Diagram A). If installing 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 (see Diagram A).

loped Ceilings
Install smoke alarms on sloped, peaked or cathedral
ceilings at, or within 0.9 m (3’) of the highest point
(measured horizontally). Smoke alarms in rooms with
ceiling slopes greater than 0.3 m - 2.4 m (1’ to 8’)
horizontally should be located on the high side of the
room. Do not place the alarm in the peak of an “A”
frame type ceiling (see Diagram B).
Mobile Homes
Modern mobile homes have been designed and built to
be energy efficient. Install Smoke/CO alarms as
recommended above (refer to Recommended
Installation Instructions and Diagram A).
In older mobile homes that are not well insulated,
extreme heat or cold can be transferred from the
outside to the inside through poorly insulated walls
and roof. This may cause a thermal barrier, which can
prevent smoke from reaching an alarm mounted on the
ceiling. In such mobile homes, install the Smoke/CO
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 (see Diagram A). 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 only!

Locations To Avoid
WARNING: Do not install in garages, kitchens,
furnace rooms or bathrooms! Install at least 1.5 m (5’)
away from any fuel burning appliance.
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. Avoid excessively dusty,
dirty or greasy areas. Dust, grease or household
chemicals can contaminate the alarm’s sensors, causing
it to not operate properly.
Place the alarm where drapes or other objects will not
block the sensor. Smoke and CO must be able to
reach the sensors to accurately detect these conditions.
Do not install in peaks of vaulted ceilings, “A” frame
ceilings or gabled roofs. Keep out of damp and humid
areas. Do not place near a diaper pail.
Install at least 30.5 cm (12”) away from fluorescent
lights as electronic noise may cause nuisance alarms.
Do not place in direct sunlight and keep out of insect
infested areas. Extreme temperatures will effect the
sensitivity of the Smoke/CO 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 (R ) is greater than 85%. Place away
from doors and windows that open to the outside.

Wiring
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 codes having jurisdiction in your
area. The multiple station interconnect wiring to the
alarms must be run in the same raceway or cable as the
AC power wiring. In addition, the resistance of the
interconnect wiring shall be a maximum of 10 ohms.
• The appropriate power source is 120 V 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.
• 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.
Wiring For AC Quick-Connect Harness:
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 safety products may be
interconnected in a multiple station arrangement: Limit
of 12 smoke alarms and/or 18 alarms total (smoke, CO,
Smoke/CO Combination, heat, etc.). This Smoke/CO
Combination alarm is counted as a smoke alarm when
determining the maximum number of units on an
interconnect line. With 18 alarms interconnected, it is
still possible to interconnect up to a total of 6 remote
signaling devices and/or relay modules (see Page 16 for
details on interconnecting Kidde devices).

Testing
CAUTION: Due to the loudness (85 decibels) of the
alarm, always stand an arms length away from the unit
when testing.
The Test/Reset/ ush®button has four purposes - it
tests the unit’s electronics, resets the CO alarm,
activates the ush®feature, and activates the Peak
Level Memory feature.
After installation, test the unit’s electronics by pressing
and releasing the Test/Reset/ ush®button. A series of
beeps will sound, followed by the message,
"Fire! Feu!" then another series of beeps and the
message, "Carbon Monoxide! Monoxyde de carbone!"
followed by 4 additional short beeps.
Weekly testing is required! If at anytime it does not
perform as described, verify that the power is
connected correctly and that the battery is fresh. Clean
any dust or other buildup on the unit. If it still does
not operate properly, call the Product Support Line at
1-800-880-6788.

Interconnect Feature
IMPORTANT: This unit is only approved to interconnect
with the Kidde line of products. It is not approved to
interconnect with any other manufacturer's products.
• When compatible smoke alarms (1235CA, 1275CA,
1276CA, 1285CA, i12020CA, i12040CA, i12060CA,
KN-SMFM-ICA, PE120CA, PI2000CA, PI2010CA) and

and their functionality in an interconnect system, visit our
web site at: www.kiddecanada.com
Hush®Control Feature
The ush®feature has the capability of temporarily
desensitizing the smoke alarm circuit for about 10 minutes.
This feature is to be used only when a known alarm
condition, such as smoke from cooking, activates the
alarm. You can put the Smoke/CO Alarm in ush®
mode by pushing the Test/Reset/ ush®button. If the
smoke is not too dense, the alarm will silence immediately,
verbally announce, "Hush®mode on! Mode Hush®
activ !", and the green LED will flash every 2 seconds for
approximately 10 minutes. This indicates that the smoke
alarm is in a temporarily desensitized condition. The alarm
will automatically reset after approximately 10 minutes.
When the unit returns to normal operation after being in
ush®mode, it will verbally announce, "Hush®mode
cancelled! Mode Hush®annul !" and sound the alarm if
smoke is still present.
Operation
16

The ush®feature can be used repeatedly until the air
has been cleared of the condition causing the alarm.
While the unit is in ush®mode, pushing the
Test/Reset/ ush®button on the alarm will also end the
ush®period.
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.
Reset Feature
If the the Smoke/CO Alarm is sounding a CO alarm,
pressing the Test/Reset/ ush®button will silence the
alarm. If the CO condition that caused the alert
continues, the alarm will reactivate. Reactivation times
depend on the amount of CO present.
Peak Level Memory
If the CO sensor has detected a CO level of 100 PPM
or higher since last reset, it will be recorded by the
Peak Level Memory function. To access the Peak Level
Memory, press the Test/Reset/ ush®button. If a
reading of 100 PPM or higher has been recorded, the
unit will announce, "Caution! Attention!" If you’ve
been away from home, this feature allows you to
check if there was a CO reading of 100 PPM or higher
during your absence. Pushing the Test/Reset/ ush®
button resets the memory. The memory is also reset
when the unit loses power.

LED Indicators
Red LED
The Red LED flashes in conjunction with the alarm.
The red LED will flash during a smoke alarm, a CO
alarm, a Low Battery Mode “chirp” and a Unit Error
Mode “chirp.”
Green LED
The green LED will flash under the following
conditions:
In Standby Condition (powered by AC and battery
backup) the green LED will be constantly on indicating
that 120 V AC power is being delivered to the alarm. It
will briefly flicker every 30 seconds when a CO
reading is taken.
For model KN-COSM-IBCA only, in Standby Condition
(powered only by battery backup) the green LED will
flash every 5 seconds.
In Alarm Memory Condition the green LED will flash
every second signifying that the alarm has sensed a
smoke or CO hazard. It will continue to flash every
second until the Test/Reset/ ush®button is pressed to
reset the alarm. When interconnected alarms cease to
sound, this flashing green LED indicates the originating
alarm that triggered all the others in the circuit, thus
reducing the time spent troubleshooting.
While in ush®Mode, the green LED will flash every 2
seconds.
