Features and General Information
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.
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. Home 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
• 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 and General Information
• 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
• Although smoke alarms can help save lives by providing an
early warning of a fire, they are not a substitute for an
insurance policy. Home 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 page 21 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.
Installation Instructions
Step 1
Installation Guide:
A. Recommended Installation Locations:
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 30 ft (9.1m) 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 4” (10cm) 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 4”
(10cm) and a maximum
of 12” (30.5cm) below
the ceiling (see figure
Installation Instructions
Sloped Ceiling Installation:
The following information is from the National Fire Protection
Association and is listed in Fire Code 72.
Install Smoke Alarms on sloped, peaked or cathedral ceilings at,
or within 3 ft (0.9m) of the highest point (measured horizontally).
NFPA 72 states “Smoke alarms in rooms with ceiling slopes
greater than 1 ft to 8 ft (.3 m-2.4 m) horizontally shall be located
on the high side of the room”.
NFPA 72 states “A row of alarms shall be spaced and located
within 3 ft (0.9 m) of the peak of the ceiling measured
horizontally” (see figure 2).
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 (see figure 2).
30 cm (12”)
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 figure
1). In older mobile homes that are not well insulated, extreme
Installation Instructions
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 4 inches (10cm) and a maximum of 12
inches (30.5cm) below the ceiling (see figure 2). 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!

Do not install within 3 ft (.9m) 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 areas. Avoid excessively dusty,
dirty or greasy areas. Dust, grease or household chemicals can
contaminate the alarm's sensors, causing it to not operate
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.
Installation Instructions

Smoke HUSH Control Feature
The HUSH feature has the capability of temporarily desensitizing
the smoke alarm circuit for approximately 9 minutes. This feature
is to be used only when a known alarm condition, such as smoke
from cooking, activates the alarm. When the unit is in alarm,You
can put your Smoke/CO Alarm in HUSH mode by pushing the
test/reset button. If the smoke is not too dense, the alarm will
silence immediately, the unit will verbally announce “HUSH
MODE ACTIVATED”, and the green LED will flash every 2 seconds
for approximately 9 minutes. This indicates that the smoke alarm
is in a temporarily desensitized condition. Your Smoke/CO Alarm
will automatically reset after approximately 9 minutes. When the
unit returns to normal operation after being in HUSH mode, it
will verbally announce “HUSH MODE CANCELLED”, 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
button on the alarm will also end the HUSH period.

engaged, press down on the tamper resist tab, and rotate the
alarm off of the bracket (see figure 5B).
Operating Instructions
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 4-7 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. 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.
What To Do If The Alarm Sounds
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.
• 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.
• 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 give the go ahead.
• There are situations where a smoke alarm may not be
effective to protect against fire as stated in the NFPA
Standard 72. For instance:
a) smoking in bed
b) leaving children unsupervised
c) cleaning with flammable liquids, such as gasoline
The CO sensor meets the alarm response time requirements of UL
standard 2034. Standard alarm times are 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.
This carbon monoxide alarm is designed to detect carbon
monoxide gas from ANY source of combustion. It is NOT
designed to detect any other gas.
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 Safety will not pay for, or reimburse,
the owner or user of this product, for any repair or dispatch calls
related to the alarm sounding.
What To Do If The Alarm Sounds
When the carbon monoxide alarm sounds:
WARNING - Actuation of your CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can kill you.
If alarm signal sounds:
1) Operate the test/reset button
2) Call your emergency
services (Fire Dept. or 911)
3) 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 reenter the premises nor move
away from the open door/window until the emergency
services responders have arrived, the premises has been
aired out, and your alarm remains in its normal
4) After following steps 1-3, if your alarm reactivates
within a 24 hour period, repeat steps 1-3 and call a
qualified appliance technician
to investigate for sources of
CO from fuel burning equipment and appliances, and
inspect for proper operation of this equipment. If

• Remove the unit from mounting bracket and vacuum the alarm
cover and vents with a soft brush attachment once a month to
• 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
Move the Smoke/CO Alarm and place in another location prior to
performing any of the following:
Staining or stripping wood floors or furniture
Wall papering
Using adhesives
Storing the unit in a plastic bag during any of the above projects will
protect the sensors from damage. Do not place near a diaper pail.
! WARNING: Reinstall the Smoke/CO Alarm as soon as possible
to assure continuous protection.
When household cleaning supplies or similar contaminates are used,
the area must be well ventilated. The following substances can
effect the CO sensor and may cause false readings and damage to
the sensor:

Carbon Monoxide Safety Information
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.
Possible Sources
CO can be produced when burning any fossil fuel: gasoline,
propane, natural gas, oil and wood. It can be produced by any
fuel-burning appliance that is malfunctioning, improperly
installed, or not ventilated correctly. Possible sources include
furnaces, gas ranges/stoves, gas clothes dryers, water heaters,
portable fuel burning space heaters, fireplaces, wood-burning
stoves and certain swimming pool heaters. Blocked chimneys or
flues, back drafting and changes in air pressure, corroded or
disconnected vent pipes, and a loose or cracked furnace
exchanger can also cause CO. Vehicles and other combustion
engines running in an attached garage and using a charcoal/gas
grill or hibachi in an enclosed area are all possible sources of CO.
The following conditions can result in transient CO situations:
Excessive spillage or reverse venting of fuel-burning appliances
caused by outdoor ambient conditions such as: Wind direction
and/or velocity, including high gusts of wind, heavy air in the vent
pipes (cold/humid air with extended periods between cycles),
negative pressure differential resulting from the use of exhaust
fans, simultaneous operation of several fuel-burning appliances
competing for limited internal air, vent pipe connections vibrating
loose from clothes dryers, furnaces, or water heaters,
obstructions in, or unconventional, vent pipe designs which can
amplify the above situations, extended operation of unvented
fuel-burning devices (range, oven, fireplace, etc.), temperature
inversions which can trap exhaust gasses near the ground, car
idling in an open or closed attached garage, or near a home.
General Maintenance
CO Safety Tips
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
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.
Symptoms of CO Poisoning
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.
The following symptoms are related to CARBON MONOXIDE
POISONING and should be discussed with ALL members of the
1. Mild Exposure: Slight headache, nausea,vomiting, fatigue
(often described as “Flu-like” symptoms).
2. Medium Exposure: Severe throbbing headache,
drowsiness, confusion, fast heart rate.
3. Extreme Exposure: Unconsciousness, convulsions,
cardiorespiratory failure, 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
Carbon Monoxide Safety Information
either exiting the building, or calling for assistance. Also, young
children and household pets may be the first effected.
Familiarization with the effects of each level is important.
Fire Safety Information
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 where 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.
Establish a rule that once you’re out, you never reenter
under any circumstance!
Current studies have shown smoke alarms may not awaken all
sleeping individuals, and that it is the responsibility of individuals
in the household that are capable of assisting others to provide
assistance to those who may not be awakened by the alarm
sound, or to those who may be incapable of safely evacuating
the area unassisted.
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.
Know how to do “Stop, Drop and Roll” if clothes catch on fire,
and how 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.

Industry Safety Standards
NFPA (National Fire Protection Association)
For your information, the National Fire Protection Association’s
Standard 72, reads as follows:
Smoke Detection. Where required by applicable laws, codes, or
standards for the specified occupancy, approved single- and
multiple-station smoke alarms shall be installed as follows: (1) In
all sleeping rooms. (2) Outside of each separate sleeping area, in
immediate vicinity of the sleeping rooms. (3) On each level of the
dwelling unit, including basements Exception: In existing oneand two-family dwelling units, approved smoke alarms powered
by batteries are permitted.
Smoke Detection - Are More Smoke Alarms Desirable? The
required number of smoke alarms might not provide reliable early
warning protection for those areas separated by a door from the
areas protected by the required smoke alarms. For this reason, it
is recommended that the householder consider the use of
additional smoke alarms for those areas for increased protection.
The additional areas include the basement, bedrooms, dining
room, furnace room, utility room, and hallways not protected by
the required 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.
California State Fire Marshall
Early warning fire detection is best achieved by the installation of
fire detection equipment in all rooms and areas of the household
as follows: A smoke alarm installed in each separate sleeping
area (in the vicinity, but outside the bedrooms), heat or smoke
detectors in the living rooms, dining rooms, bedrooms, kitchens,
hallways, attics, furnace rooms, closets, utility and storage rooms,
basements and attached garages.
Consumer Product Safety Commission
The Consumer Product Safety Commission (CPSC) recommends
