Carbon Monoxide Alarm Procedure
WA NING: Activation of the CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can kill you.
What to do When the Alarm Sounds!
If the alarm sounds 4 quick “beeps”, 5 seconds off:
1) Immediately move to fresh air – outdoors or by an open
door/window. Do a head count to check that all persons
are accounted for. Do not re-enter the premises nor move
away from the open door/window until the emergency
services responders have arrived, the premises have been
aired out, and your alarm remains in its normal condition.
2) Call your local emergency service.
(fire department or 911)
Never restart the source of a CO problem until it has
been corrected. Never ignore the sound of the alarm!
If the alarm is sounding, pressing the test/reset button
will terminate the alarm. If the CO condition that caused
the alert in the first place continues, the alarm will
reactivate. If the unit alarms again within six minutes, it
is sensing high levels of CO which can quickly become a
dangerous situation.
PHONE NUMBER:

NEVER IGNORE THE SOUND OF THE ALARM!
Determining what type of alarm has sounded is easy with your
Combination Smoke/CO Alarm. The voice message warning
system will inform you of the type of situation occurring. Refer
to the Features section on pages 4-5 for a detailed description
of each alarm pattern.
What To Do If The Alarm Sounds
When the smoke alarm sounds:
Smoke alarms are designed to minimize false alarms. Cigarette
smoke will not normally set off the alarm, unless the smoke is
blown directly into the alarm. This unit contains nuisance alarm
protection, which will reduce the impact of cooking particles.
owever, large quantities of combustible particles from spills or
broiling could still cause the unit to alarm. Careful location of the
unit away from the kitchen area will give the maximum nuisance
alarm protection. Combustion particles from cooking may set off
the alarm if located too close to the cooking area. Large quantities
of combustible particles are generated from spills or when broiling.
Using the fan on a range hood which vents to the outside (non-
recirculating type) will also help remove these combustible
products from the kitchen.
If the alarm sounds, check for fires first. If a fire is discovered
follow these steps. Become thoroughly familiar with these items,
and review with all family members!
• Alert small children in the home. Children sleep very
sound and may not be awakened by the sound of the
smoke alarms.
• Leave immediately using one of your planned escape
routes (see page 26). Every second counts, don’t stop
to get dressed or pick up valuables.
What to do When the Alarm Sounds!

What to do When the Alarm Sounds!
• Before opening inside doors look for smoke seeping in
around the edges, and 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 immediately if smoke and heat rush in.
• If the escape route requires you to go through smoke,
crawl low under the smoke where the air is clearer.
• Go to your 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 reenter under any circumstance 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 noted
by the NFPA Standard 72. For instance:
- Smoking in bed
- eaving children unsupervised
- Cleaning with flammable liquids, such as gasoline
- Fires where the victim is intimate with a flaming
initiated fire; for example, when a person's
clothes catch fire while cooking
- Fires where the smoke is prevented from reaching
the detector due to a closed door or other
obstruction
- Incendiary fires where the fire grows so rapidly that
an occupant's egress is blocked even with
properly located detectors

Smoke Alarm
The smoke alarm 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, and be accompanied by the flashing red LED light. The
smoke alarm takes precedence when both smoke and carbon
monoxide are present.
WA NING: PLEASE EAD CA EFULLY AND
THO OUGHLY
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
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.
• 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.
!

Features

• 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.
• Although smoke alarms can help save lives by providing an
early warning of a fire, they are not a substitute for an
insurance policy. ome owners and renters should have
adequate insurance to protect their lives and property.
Carbon Monoxide (CO) Alarm
The Carbon Monoxide (CO) alarm 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 below for alarm times). When a CO
condition matches either of these situations, the alarm/voice
message warning system will sound, and be 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.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm.
!
Features

Never restart the source of a CO problem until it has
been fixed. NEVER IGNORE THE A ARM!
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.

Step 1 Installation Instructions
IMPORTANT: THIS A ARM MUST BE MOUNTED ON A
CEI ING OR WA . IT WAS NOT DESIGNED FOR USE AS A
TAB ETOP DEVICE! INSTA ON Y AS DIRECTED!
A. Recommended Installation ocations:
Kidde Safety 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,
including every bedroom, hallways, finished attics and
basements. Put alarms at both ends of bedroom, hallway or
large room if hallway or room is more than 9.1m (30 ft) 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 10cm (4”) from
the side wall (see figure 1). If installing the alarm on the wall, use
an inside wall with the top edge of the alarm at a minimum of 10cm
(4”) and a maximum of 30.5cm (12”) below the ceiling (see figure 1).

Sloped Ceiling Installation:
Install smoke alarms on sloped, peaked or cathedral ceilings
at, or within 0.9 m (3’) of the highest point (measured
horizontally). NFPA 72 states “Smoke alarms in rooms with
ceiling slopes greater than 0.3 m – 2.4 m (1’ to 8’)
horizontally shall be located on the high side of the room”.
Do not place the alarm in the peak of an “A” frame type
ceiling (see Figure 2B and 2C).
Mobile Homes:
Modern mobile homes have been designed and built to be
energy efficient. Install Smoke/CO alarms as recommended
previously (refer to Recommended Installation Instructions
and Figure 2B).
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 your 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 Figure 1).
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 your alarm on an inside wall
ONLY!

Installation Instructions

B. ocations to Avoid:
WARNING: Do not install in garages, kitchens,
furnace rooms or bathrooms! INSTA AT EAST 1.5 M
(5’) AWAY FROM ANY FUE BURNING APP IANCE.
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 the alarm to not operate properly.
Place the alarm where drapes or other objects will not block
the sensors. 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.
Install at least one 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 affect 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.

Installation Instructions
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.

Step 2: Wiring Instructions
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 Volt AC Single Phase
supplied from a non-switchable circuit, which is not protected
by a ground fault interrupter.
• Smoke alarms are not to be used with detector guards unless
the combination (alarm and detector guard) have been
evaluated and found suitable for that purpose.
•WARNING: The alarm cannot be operated from power
derived from a square wave, modified square wave or
modified sine wave, inverter. 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.
These power sources produce high peak voltages that will
damage the alarm.
IRING INSTRUCTIONS FOR AC QUICK CONNECT HARNESS
CAUTION! TURN OFF THE MAIN PO ER TO THE
CIRCUIT BEFORE IRING THE ALARM.
• For alarms that are used as single station, DO NOT CONNECT
T E RED WIRE TO ANYT ING. 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.
!
12
Installation Instructions

• A maximum of 24 Kidde Safety 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, CO,
Smoke/ CO Combination, heat, etc.). This Smoke/CO
combination alarm must be counted as a smoke alarm when
determining the 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).
• The maximum wire run distance between the first and last
unit in an interconnected system is 305 m (1000’).
• Figure 2 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 isted household wire (as
required by local codes) available at all electrical
supply stores and most hardware stores.
