F e a t u r e s F e a t u r e s

Smoke 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 re a c h
a specified concentration, the alarm/voice message warn i n g
system will sound, accompanied by the flashing red LED light.

NOTE: The smoke alarm takes precedence when both
smoke and carbon monoxide are present.

WA R N I N G : PLEASE READ CAREFULLY AND T H O RO U G H L Y

N F PA Standard 72 states: Life safety from fire in re s i d e n t i a l
occupancies is based primarily on early notification to
occupants of the need to escape, followed by the
a p p r opriate egress actions by those occupants. Fire warn i n g
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 pro t e c t i o n - i n - p l a c e
or assisted escape or rescue are necessary.

• Smoke alarms are devices that can provide early warn i n g
of possible fires at a reasonable cost, however, alarm s
have sensing limitations. Ionization type alarms offer a
b r oad range of fire sensing capabilities but are better at
detecting fast flaming fires than slow smoldering fire s .
Photoelectric alarms sense smoldering fires better than
flaming fires. Home fires develop in diff e r ent ways and
a r e often unpredictable. Neither type of alarm

(photoelectric or ionization) is always best, and a
given alarm may not always provide warning of a fire.

• A battery powered alarm must have a battery of the
specified type, in good condition and installed pro p e r l y .

• 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. There f o re, smoke alarms may not
sense fires starting in chimneys, walls, on roofs, on the
other side of a closed door or on a diff e r ent 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 (see Page 24
for alarm times). 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 electro c hemical tech n o l o gy.
C AU T I O N : This alarm will only indicate the presence of

carbon monoxide gas at the sensor. Carbon monoxide gas
m a y be present in other are a s .

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
w a r ning 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.

commercial or industrial standards.

IMPORTANT: This alarm must be mounted on a ceiling
or wall. It was not designed for use as a tabletop device.
Install only as directed.

Kidde recommends the installation of a Smoke/CO
Alarm in the following locations. For maximum
protection we 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
the alarm 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).

It is not designed to measure compliance with

I n s t a l l a t i o n

I n s t a l l a t i o n

Sloped 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

Mobile homes built within the last five to seven years
are designed to be energy efficient. Install Smoke/CO
alarms as recommended above (refer to Recommended
Installation Instructions and Diagram A).

In 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 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). Do not
install in areas where the relative humidity (RH) is
greater than 85%. Place away from doors and
windows that open to the outside.

Wiring

Wiring Requirements:

• This Smoke/CO Alarm should be installed on a CSA
listed or recognized junction box. All connections
should be made by a qualified electrician and must
conform to codes having jurisdiction in your area.

• 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.

• The alarm should not be operated on power derived
from a square wave or modified square 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 any t h i n g. 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

I n s t a l l a t i o n

devices and/or relay modules (see Page 16 for
details on interconnecting Kidde devices).

• The maximum wire run distance between the first
and last unit in an interconnected system is 305 m
(1000’).

• Figure 1 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 (non­switched) power line.

NOTE: Use standard CSA listed household wire
(18 gauge or larger as required by local codes) available
at all electrical supply stores and most hardware stores.

units and their functionality in an interconnect system,
visit our web site at: www.kidde.ca

Hush®Control Feature

The Hush®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 Hush®mode by pushing the Test/Reset/Hush

®

button. If the smoke is not too dense, the alarm will
silence immediately, verbally announce, "Hush®mode
on! Mode Hush®activé!", 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 Hush

®

mode, it will verbally announce, "Hush®mode
cancelled! Mode Hush®annulé!" and sound the alarm
if smoke is still present.

The Hush®feature can be used repeatedly until the air
has been cleared of the condition causing the alarm.

While the unit is in Hush®mode, pushing the
Test/Reset/Hush®button on the alarm will also end the
Hush®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/Hush®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 (see Page 24).

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/Hush®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 or higher
during your absence. Pushing the Test/Reset/Hush

®

button resets the memory. The memory is also reset
when the unit loses power.

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 breifly flicker every 30 seconds when a CO
reading is taken.

For model KN-COSM-IBCA only, in Standby Condition
( p o w e r ed 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/Hush®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.

Carbon Monoxide Safety

To keep this Smoke/CO Alarm in peak condition:

• Verify the unit's alarm and LED lights operation by

pushing the Test/Reset/Hush®button once a week.

• Remove the unit from mounting plate and vacuum

the alarm cover and vents with a soft brush
attachment at least once a year to remove dust and
dirt. Reinstall immediately after cleaning and then
test using the Test/Reset/Hush®button.

• Never use detergents or other solvents to clean the

unit.

• Avoid spraying air fresheners, hair spray, or other

aerosols near the Smoke/CO Alarm.

Do not paint the unit. Paint will seal the vents and
interfere with the sensor’s ability to detect smoke and
CO. Never attempt to disassemble the unit or clean
inside. This action will void your warranty.

Move the Smoke/CO Alarm to another location prior to
performing any of the following:

• Staining or stripping wood floors or furniture

• Painting or wall-papering

• Using adhesives

Storing the unit in a plastic bag during any of the
above projects will protect the sensors from damage.

WARNING: Reinstall the Smoke/CO Alarm as soon as
possible to assure continuous protection.

When household cleaning supplies or similar
contaminants are used, the area must be well
ventilated. The following substances can affect the CO
sensor and may cause false readings and damage to
the sensor: Methane, propane, iso-butane, iso­propanol, ethyl acetate, hydrogen sulfide, sulfide
dioxides, alcohol based products, paints, thinner,
solvents, adhesives, hair spray, after shave, perfume,
and some cleaning agents.

General CO Information

Carbon monoxide (CO) is a colorless, odorless, and
tasteless poison gas that can be fatal when inhaled. CO
inhibits the blood’s capacity to carry oxygen.

Symptoms of CO Poisoning

The following symptoms are related to carbon
monoxide poisoning and should be discussed with ALL
members of the household:

Mild Exposure: Headaches, running nose, sore eyes,

often described as "flu"-like symptoms.

Medium Exposure: Dizziness, drowsiness, vomiting.

Extreme Exposure: Unconsciousness, brain damage,

death.

The above levels of exposure relate to healthy adults.
Levels differ for those at high risk. Exposure to high
levels of carbon monoxide can be fatal or cause
permanent damage and disabilities. Many cases of
reported carbon monoxide poisoning indicate that
while victims are aware they are not well, they become
so disoriented they are unable to save themselves by
either exiting the building, or calling for assistance.
Also, young children and household pets may be the
first affected. Familiarization with the effects of each
level is important.

Carbon Monoxide Safety

Carbon Monoxide Safety

Initial carbon monoxide poisoning symptoms are
similar to the flu with no fever and can include
dizziness, severe headaches, nausea, vomiting and
disorientation. Everyone is susceptible, but experts
agree that unborn babies, pregnant women, senior
citizens and people with heart or respiratory problems
are especially vulnerable. If symptoms of carbon
monoxide poisoning are experienced, seek medical
attention immediately. CO poisoning can be
determined by a carboxyhemoglobin test.

CO Sensor Response Times

The CO sensor meets the alarm response time
requirements as follows:

At 70 PPM, the unit must alarm within 60-240 minutes.

At 150 PPM, the unit must alarm within 10-50 minutes.

At 400 PPM, the unit must alarm within 4-15 minutes.

NOTE: This carbon monoxide alarm is designed to
detect carbon monoxide gas from ANY source of
combustion. It is NOT designed to detect any other
gasses.

Fire departments, most utility companies and HVAC
contractors will perform CO inspections. Some may
charge for this service. It’s advisable to inquire about
any applicable fees prior to having the service
performed. Kidde will not pay for, or reimburse, the
owner or user of this product, for any repair or
dispatch calls related to the alarm sounding.

Possible Sources of CO

CO can be produced when burning any fossil fuel, such
as gasoline, propane, natural gas, oil and wood. It can
be produced by any fuel-burning appliance that is
malfunctioning, improperly installed, or not ventilated
c o r rectly, such as:

• Fu rnaces, gas ranges/stoves, gas clothes dryers, water
heaters, portable fuel burning space heaters,
f i rep laces, wood-burning stoves and certain
swimming pool heaters.

• Blocked chimneys or flues, back drafts and changes
in air pre s s u re, corroded or disconnected vent pipes,
loose or cracked furnace exchangers.

• Vehicles and other combustion engines running in an
open or closed garage, attached or near a home.

• C h a rco al/gas grills and hibachis in an enclosed are a .

Carbon Monoxide Safety

The fo l l owin g conditions can result in transient CO
s i t u a t i o n s :

Excessive spillage or reverse venting of fuel-burn i n g
appliances caused by:

• outdoor ambient conditions, such as wind direction
and/or velocity, including high gusts of wind, and
insufficient draft in the vent pipes;

• negative pressure differential resulting from the use
of exhaust fans;

• simultaneous operation of several fuel-burning
appliances competing for limited internal air;

• loose vent pipe connections from fuel-fired
appliances;

• obstructions, or unconventional vent pipe designs
that can amplify the above situations;

• poorly designed or maintained chimneys and/or
vents;

Extended operation of unvented fuel-burning devices
(range, oven, fireplace, etc.);

Temperature inversions that can trap exhaust gasses
near the ground; and a

Car idling in an open or closed attached garage, or
near a home.

Every year, have the heating system, vents, chimney
and flue inspected and cleaned by a qualified
technician. Always install appliances according to
manufacturer’s instructions and adhere to local building
codes. Most appliances should be installed by
professionals and inspected after installation. Regularly
examine vents and chimneys for improper connections,
visible rust, or stains, and check for cracks in furnace
heat exchangers. Verify that the color of flame on pilot
lights and burners is blue. A yellow or orange flame is
a sign that the fuel is not burning completely. Teach
all household members what the alarm sounds like and
how to respond in an emergency.

Carbon Monoxide Safety

Carbon Monoxide Alarm Procedur e

WARNING: Actuation of the CO Alarm

indicates the presence of Carbon Monoxide
(CO) which can KILL YOU.

If alarm signal sounds 4 quick beeps, 5 seconds off:

1) Immediately move to fresh air - outdoors or by an
open door or window. Check that all persons are
accounted for. Do not re-enter the premises or
move away from the open door/window until
emergency services responders have arrived, the
premises have been aired out, and your alarm
remains in its normal operating condition.

2) Call your emergency local service
(fire deptartment or 911).

PHONE NUMBER

Never restart the source of a CO problem until it has
been corrected. NEVER IGNORE THE SOUND OF THE
ALARM!

F i r e Safety

Escape Plan

Familiarize everyone with the sound of the smoke alarm
and train them to leave the 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. Know two ways out of every room (door &
window) and identify a meeting place outside the home
w h e r e everyone will gather once they have exited the
residence. When two people have reached the meeting
place, one should leave to call 911 while the second
person stays to account for additional family members.

Smoke Alarm Procedure

Smoke alarms are designed to minimize false alarms.
Cigarette smoke will not normally set off the alarm,
unless it’s blown directly into the alarm. Combustion
particles from spills or broiling may set off the alarm if
located too close to the cooking area. If the alarm
sounds, check for fires first. If a fire is discovered
follow these steps. Become thoroughly familiar with
these steps, and review them with all family members.

• Alert small children in the home.

• Leave immediately using one of your planned
escape routes (see above).

• Before opening inside doors look for smoke seeping
through the edges. Feel with the back of your hand

- if the door is hot use your second exit. If you feel
it’s safe, open the door very slowly and be prepared
to close it immediately if smoke and heat rush in.

• If the escape route requires going through smoke,
crawl low under the smoke where the air is clearer.

F i r e Safety

• Go to a predetermined meeting place. When two
people have arrived, one should leave to call 911
from a neighbor’s home, and the other should stay
to perform a head count.

• Do not re-enter until fire officials say that it is safe 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:

- smoking in bed;

- leaving children unsupervised;

- cleaning with flammable liquids, such as gasoline.

Fire Prevention

Never smoke in bed, or leave cooking food
unattended. Teach children never to play with
matches or lighters! Train everyone in the home to
recognize the alarm pattern, voice message warning
and to leave the home using their escape plan when
it’s heard. Be prepared to stop, drop and roll if clothes
catch on fire, and to crawl low under smoke. 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.
Second level and higher occupied rooms with
windows, should have an escape ladder.

Additional Recommendations

Required number of smoke alarms: Smoke alarms
should be installed outside of each separate sleeping
area in the immediate vicinity of the bedrooms and on
each additional story of the family living unit (home),
including basements.

Some jurisdictions require that in new construction, a
smoke alarm be installed in each sleeping room.
Check with local officials for specific regulations
concerning your situation.

The required number of smoke alarms (protected areas
mentioned above) might not be reliable enough to
provide early warning for unprotected areas that are
separated by a door. For this reason, it is
recommended that the householder consider the use of
additional smoke alarms for those unprotected areas,
for increased protection. Additional areas include the
basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the
required number of smoke alarms.

The installation of smoke alarms in kitchens, attics
(finished or unfinished), or garages is not normally
recommended, as these locations occasionally
experience conditions that can result in improper
operation.
