1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps with voice “Fire!,” a 1.5 second pause, and three
long beeps repeating. The red LED blinks in time with the alarm pattern only on the alarm(s) that
detected the hazard (initiating alarm).
The smoke alarm takes precedence when both smoke and carbon monoxide are present.
(only combination smoke/CO models detect carbon monoxide)
• Alert small children in the home as well as anyone else that might have difficulty recognizing the
importance of the alarm sounding or that might have difficulty leaving the area without help.
• Plan two ways out! Leave immediately by your escape plan. Don’t waste time getting dressed or
picking up valuables.
• While leaving, don’t open any inside door without first feeling its surface. If hot, or if you see
smoke seeping through cracks, don’t open that door! Instead, use your alternate exit. If the inside
of the door is cool, place your shoulder against it, open it slightly and be ready to slam it shut if
heat and smoke rush in.
• If the escape route requires you to go through smoke, stay close to the floor where the air is
cleaner. Crawl if necessary, and breathe shallowly through a cloth, wet if possible.
• Once outside, go to your selected meeting place and make sure everyone is there.
• Call the fire department or 911 from your cell phone outside, or from your neighbor’s home-not
from yours!
• Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

4. Introduction, Product Features And Specifications
Introduction
This alarm detects products of combustion using a photoelectric sensor and carbon monoxide (on
combination smoke/CO models only) using an electrochemical cell. Many times throughout this User
Guide, we will refer to Carbon Monoxide as “CO.”
Ten (10) years after the unit was installed, powered up, and tested, this unit will automatically alert you
that it is time to replace the unit. This is called “End of Unit Life” mode. See Troubleshooting Guide. To
help identify the date to replace the unit, a label has been affixed to the side of the alarm. Write the
“Install date” in the space provided, and then write in the “Replace by” date (10 years from initial power
up) in an oil based permanent marker on the label prior to installing the unit. For combination smoke/
CO models, two labels have been provided that have important information on what to do in case of a
CO alarm. Place one label at eye level on a wall near the alarm after it is mounted, and one near a fresh
air source such as a door or window, where you plan to gather after the alarm indicates the presence of
carbon monoxide.

Wire-Free Interconnect
These models have Wire-Free Interconnect capability. When one Wire-Free Interconnect unit sounds
an alarm, all other compatible Wire-Free Interconnected units will also alarm.
NOTE: Wire-Free Interconnect steps must be completed for the Wire-Free Interconnect function to
work.
The following models can be interconnected using the Wire-Free Interconnect feature: RGSDR-RW,
RGCUDR-RW.
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 or smoke/CO
combination alarms and/or 18 alarms total (smoke, CO, smoke/CO combination, heat, etc.). With 18
alarms interconnected, it is still possible to interconnect up to a total of 6 remote signaling devices and/
or relay modules.
Notifications to a Mobile Device
These models have Wi-Fi capability, and can send alarm signals and other notifications to a mobile
device. The Ring app is required, along with a home Wi-Fi router and internet. ( Requires 802.11b/g/n
(2.4GHz) Wi-Fi )
Over The Air (OTA) Firmware Updates
Your device has the ability to receive over-the-air (OTA) firmware updates to ensure the device is
working properly at all times. Most of these firmware updates go unnoticed and are successful. In the
event that an OTA event is unsuccessful after multiple attempts the device will alert you using chirp
patterns and LED lights - see Troubleshooting Guide for more details.

5. Limitations Of Smoke And Carbon Monoxide Alarms
WARNING:
PLEASE READ CAREFULLY AND THOROUGHLY
• 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.
• 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 home alone
c) cleaning with flammable liquids, such as gasoline
• Fire warning systems for dwelling units are capable of protecting about half of the occupants in
potentially fatal fires. A smoke alarm may not be effective in some situations, such as during incendiary
fires where the fire grows so rapidly that an occupant’s egress is blocked even with properly located
smoke alarms, or when victims are intimate with the fire (for example, when a person’s clothes catch fire
while cooking), 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, additional strategies
such as protection-in-place or assisted escape or rescue are necessary. *
• This model meets the latest residential smoke alarm standards, which includes enhanced resistance
to nuisance alarms from cooking. Industry experts recommend that both ionization and photoelectric
smoke alarms be installed to help ensure optimal detection of the various types of fires that can occur
within the home. 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.
• 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 battery 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, within walls, on roofs, on the other side of a closed door or other
obstructions.
• If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
13
• The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For optimal detection,
a smoke alarm should be installed in each sleeping area on every level of a home.
This alarm is not intended to alert hearing impaired individuals.
* Reference National Fire Protection Association (NFPA) standard 72
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
IMPORTANT: Combination smoke/CO alarms are designed to detect carbon monoxide gas from ANY
source of combustion. They are NOT designed to detect any other gas.
CAUTION: Combination smoke/CO alarms will only indicate the presence of carbon monoxide gas
at the sensor. Carbon monoxide gas may be present in other areas. Never restart the source of a CO
problem until it has been fixed. NEVER IGNORE THE ALARM!
WARNING: COMBINATION SMOKE/CO ALARMS ARE INTENDED FOR USE IN ORDINARY
INDOOR LOCATIONS OF FAMILY LIVING UNITS. THEY ARE NOT DESIGNED TO MEASURE
COMPLIANCE WITH OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA)
COMMERCIAL OR INDUSTRIAL STANDARDS. THEY ARE NOT SUITABLE FOR INSTALLATION
IN HAZARDOUS LOCATIONS AS DEFINED IN THE NATIONAL ELECTRIC CODE. THEY ARE NOT
DESIGNED FOR USE IN A RECREATIONAL VEHICLE (RV) OR BOAT.
• The installation of combination smoke/CO alarms should not be used as a substitute for proper
installation, use, and maintenance of fuel burning appliances, including appropriate ventilation and
exhaust systems.
• Combination smoke/CO alarms do not prevent CO from occurring, nor can they solve any existing CO
problem.
WARNING: COMBINATION SMOKE/CO ALARMS ARE DESIGNED TO HELP PROTECT
INDIVIDUALS FROM ACUTE EFFECTS OF CARBON MONOXIDE EXPOSURE. THEY WILL NOT
FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC MEDICAL CONDITIONS. IF IN DOUBT,
CONSULT A MEDICAL PRACTITIONER. INDIVIDUALS WITH MEDICAL PROBLEMS MAY
CONSIDER USING WARNING DEVICES WHICH PROVIDE AUDIBLE AND VISUAL SIGNALS FOR
CARBON MONOXIDE CONCENTRATIONS UNDER 30 PPM. *
• The combination smoke/CO alarm has not been investigated for carbon monoxide alarm below 70 PPM.
• This device requires a continuous supply of electrical power from a healthy battery or AC connection,
depending on the model. It will not work without power.
* Reference Underwriters Laboratories (UL) standard 2034.

Recommended Locations For Smoke And Carbon Monoxide Alarms
• Locate smoke alarms in all sleeping areas. 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.
• Locate additional alarms in stairways, because stairways act like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• 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.

• For all alarm locations, be sure to choose a flat, solid surface for mounting, with no holes or gaps
under the mounting bracket.
• For mobile home installation, select locations carefully to avoid thermal barriers that may form at
the ceiling. For more details, see MOBILE HOME INSTALLATION section.
• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a
maximum of 12” (30.5 cm) below the ceiling.
• Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more
than 30ft (9.1 m) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft (0.9m) of the highest
point (measured horizontally).
• Industry experts recommend a CO alarm be installed on each level of the home-ideally on any
level with fuel burning appliances and outside of sleeping areas.
This equipment should be installed in accordance with the National Fire Protection Association’s 72
(National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
Mobile Home Installation
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms
as recommended above. 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 which 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 a maximum of 12” (30.5 cm) below the ceiling.
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 compared to the room air temperature, install the alarm on an inside wall.
NFPA 72 (National Fire Protection Association) requires smoke alarms be installed in each sleeping area.
WARNING: TEST YOUR ALARM OPERATION AFTER MOBILE HOME HAS BEEN IN STORAGE
OR UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.
17
7. Locations To Avoid
（See Figures 6-A, 6-B, & 6-C for recommended locations）
• In the garage. Products of combustion are present when you start your automobile.
• Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm
silence feature and should not be installed within 6 ft (1.8m) of cooking appliances.
• Do not install within 6 ft (1.8m) of heating appliances.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40 °F (4.4 °C) or rise above 100 °F (37.8 °C), such
as garages and unfinished attics.
• In dusty areas. Dust particles may cause nuisance alarms or a failure to alarm.
• In very humid areas (above 95% RH, non-condensing) as moisture or steam can cause nuisance
alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (0.9m) of the door to a bathroom containing 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.
• Near lights. Electronic “noise” generated by the lights may cause nuisance alarms.
• Do not install near vents, flues, or chimneys.
• Do not install near fans, doors, windows or areas directly exposed to the weather.
• Avoid installing where the unit will be exposed to direct sunlight.
• Do not install DC (battery only) alarms on top of AC electrical junction boxes.
NOTE: Smoke alarms are not to be used with detector guards unless the combination (alarm and
detector guard) has been evaluated and found suitable for that purpose.
18
8. Activation / Installation
NOTE:
Do not power your smart alarm until prompted in the Ring app to ensure best Wi-Fi enrollment results.
For the easiest experience, follow these steps:
(A) install one alarm and enroll it in Wi-Fi using the app
(B) repeat install/Wi-Fi for each alarm
(C) set up the Wire-Free Interconnect network (section 9).
Refer to the Troubleshooting Guide if you have problems.
NOTE: A dust cover has been installed on the alarm. Keep the dust cover on until all construction has
been completed for at least 24 hours (drywall, painting, varnishing, mounting plate install, etc). Retain
the dust cover and re-install it to protect the alarm during future construction projects. Construction
dust and chemicals can cause contamination and false alarms.
WARNING:
DUST COVER MUST BE REMOVED FOR ALARM TO OPERATE.
NOTE: Single station alarms are units that are not connected to other alarms in any manner, including
Wire-Free Interconnect.
• Single statio
n alarms (including these models, if used as a single station alarm) CANNOT send or
receive alarm signals to other alarms in your home.
• These units will emit a series of LED blinks, tones, and voices as the unit(s) search for a Wi-Fi
alarm network. If you are intending to use these units without the Wi-Fi function, ignore these
notifications, and the Wi-Fi will turn off in about 15 minutes. You can turn the Wi-Fi functions on
again at a later date if desired (see Section Resetting a Device’s Wireless Settings).
STEP 1: Activate Battery
Pull out the battery pull tab first to activate the batteries (see
Figure 8-A). Battery activation is confirmed with a beep and
voice “Ready for Wi-Fi Setup, follow quick start instructions.” If
the beep and voice do not occur when the battery pull tab is
removed, remove the batteries and reinstall them. Confirm the
battery activation beep and voice.
Figure 8-A
19
STEP 2: Install Mounting Bracket
NOTE: Kidde alarms are not designed, agency tested or certified for recessed mounting and should
not be installed in this manner. Recessed mounting impedes smoke entry into the smoke chamber,
which may prevent the alarm from sounding in a timely manner. This could endanger the lives of
occupants in the residence. Kidde alarms are designed, tested and certified for wall (if applicable)
and ceiling surface mount only.
After selecting the proper location for your alarm, attach the mounting bracket to the wall or
ceiling. To ensure aesthetic alignment of the alarm with the hallway, or wall, the “A” line on the
mounting bracket should be parallel with the hallway when ceiling mounted, or horizontal when
wall mounted. (Figures 8-B and 8-C)

12. Operation And Testing
This model meets the latest residential smoke alarm standards, which includes enhanced
resistance to nuisance alarms from cooking.
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). When
products of combustion (smoke for smoke only models, and smoke or CO for combination smoke/CO
models) are sensed, the unit sounds a loud alarm with voice messages. See Sections 1 and 2 for alarm
signal descriptions. In high levels of CO, the unit will go into alarm in a shorter period of time than at
low levels of CO (combination smoke/CO models only).
27

Testing
NOTE: For a smooth testing experience, please ensure Practice Mode is enabled prior to testing any of
your alarms. This can be found in the Monitoring section of your Ring app, if you are subscribed to Ring’s
Professional Monitoring service. For more details visit: ring.com/support
WARNING: Do not attempt to test this unit with retail “canned smoke” products. Those products are
intended for use by trained professionals and produce inconsistent results when misused.
Over-application of canned smoke can permanently damage the alarm.
Self -Testing
This model is equipped with internal, self-testing components that are always checking to ensure the
device is operating as expected. (Weekly manual testing is still required. See below.)
Manual Testing
NOTE: When pushing the Test/Hush button, use only your finger
or thumb. Using any other instrument(s) (such as a broom handle) is
strictly prohibited, as it may damage the alarm.
Test your alarm weekly by pressing and releasing the Test/Hush
button quickly (Figure 12). A quick beep will confirm the Test/Hush
button has been pushed followed by the test sequence. See Other
Alarm Visual and Audible Indicators table. The alarm and voice (and
any interconnected units) will sound if the electronic circuitry, horn,
speaker, and batteries are working. If the alarm or voice does not
sound, or gives erratic or low volume sound, the unit must be replaced.
NOTE: If you push the Test/Hush button on your alarm, the app will
send you a text message.
WARNING: Due to the loudness of the alarm, always stand about 2.5 ft (0.8 m) away from the unit or
use ear protection when testing.
WARNING: Do not use an open flame to test your alarm, you could damage the alarm or ignite
combustible materials and start a structure fire.

13. Recognizing Nuisance Alarms
Smoke Nuisance
This model meets the latest residential smoke alarm standards, which includes enhanced resistance to
nuisance alarms from cooking.
HUSH
TM
: If you know why the alarm is sounding, and you can verify that it is not a life threatening
situation, you can push the Test/Hush button on the initiating unit (red LED blinking) to silence the alarm
for 8-10 minutes. If the smoke is not too dense, that unit, and all interconnected units will silence. After
the HUSH time period has elapsed, the smoke alarm will automatically reset and sound the alarm if
particles of combustion are still present. You can use the HUSH function repeatedly until the air has
been cleared of the condition causing the alarm.
NOTE: Dense smoke will override the HUSH function and sound a continuous alarm. If no fire is
present, check to see if one of the reasons listed in “Locations to avoid” may have caused the alarm. If
a fire is discovered, get out and call the fire department or 911.
Cigarette smoke will not normally cause the unit to alarm, unless the smoke is blown directly into the
alarm. Combustion particles from cooking may set off the alarm if it is located too close to a cooking
appliance. 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 prevent
nuisance alarms from occurring by removing these combustible products from the kitchen.
Carbon Monoxide (CO) Nuisance (combination smoke/CO models only)
RESET: Pushing the Test/Hush button on a combination smoke/CO unit during CO alarm allows the unit
to reset calculations and double check for the presence of CO. If the unit re-alarms within 6 minutes, it is
sensing high levels of CO which can quickly become a dangerous situation. Exit to fresh air and call 911.
LOCATE:
In a Wire-Free Interconnect system (all units will be alarming together), a unit that detects smoke or CO
and initiates an alarm is called the “initiating alarm unit.” Initiating alarm units will be flashing the red LED
during alarm. Depending on unit locations, and the location of the source of smoke or CO, it is possible
to have more than one initiating unit. If you suspect a nuisance alarm situation, you can use this feature
to help you locate the initiating alarm unit(s) in a Wire-Free Interconnected system. Push the button
Chirping
If your device begins chirping for End of Unit Life or Low Battery, you can temporarily silence
these chirps by pressing the Test/Hush button. Other fault /error chirps cannot be silenced. Take
appropriate action as described in the Troubleshooting Guide.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE. SEVEN (7)
DAYS AFTER END OF UNIT LIFE BEGINS, THE NOTIFICATIONS CANNOT BE SILENCED, AND
SMOKE AND/OR CO DETECTION CANNOT BE GUARANTEED. REPLACE IMMED
IATE LY!
29
14. Batteries
These models are powered with two replaceable AA batteries. Under normal conditions, fresh
batteries will last at least one year.
NOTE: Constant exposure to high or low humidity or temperatures, or poor Wi-Fi or Wire-Free
Interconnect signal, may reduce battery life.
WARNING: THE ALARM IS SEALED AND THE COVER IS NOT REMOVABLE.
Low Battery
This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point
where it can no longer provide adequate power for all alarm functions, the low battery condition
will occur. See Troubleshooting Guide. The batteries must be replaced within 7 days of the first
occurrence of the “Low Battery Warning” to provide continuous alarm detection. Replacing
batteries will not erase your Wi-Fi or Wire-Free Interconnect connections.
WARNING: Use only the batteries specified. Use of different
batteries may have a detrimental effect on the alarm. Do not mix old and
new batteries. Do not mix alkaline, standard, or rechargeable batteries.
NOTE: Do not use lithium batteries in this unit. A good safety
measure is to replace the batteries at least once a year, or at
the same time you change your clocks for daylight saving time.
A missing or improperly installed battery will render the unit
inoperable.
WARNING: Failure to install batteries in the correct orientation will
prevent proper operation of this alarm and will prevent its response to
fire and/or CO hazards.
Figure 14
Replace batteries with one of the following approved brands:
Energizer E91, Gold Peak 15A or Golden Power GLR6A.
These batteries can be purchased at your local retailer.
on any non-initiating Wire-Free Interconnect unit, and ALL Wire-Free Interconnect units EXCEPT the
initiating alarm unit(s) will silence for two minutes. You can use the LOCATE feature repeatedly until you
find the initiating alarm unit(s), or the air has been cleared of the condition causing the alarm.
NOTE: HUSH
TM
and Locate features are dependent on the type of models in your interconnect system.
Non-wireless models cannot receive the wireless Locate feature and will continue to alarm until the
initiating unit is Hushed or the Smoke/ CO condition clears.
WARNING: ALTHOUGH RESET FEATURE CAN BE USED FOR CO ALARM EVENTS, IT IS
IMPOSSIBLE TO DETERMINE THE SOURCE OF A CO ALARM USING SIGHT OR SMELL. ALWAYS
CONSIDER A CO ALARM EVENT AS DANGEROUS.
NOTE: If either battery is
missing, the alarm cannot mount
on the mounting bracket.
30
15. Carbon Monoxide Alarm: What To Do When The Alarm Sounds
NOTE: Smoke only models do not detect carbon monoxide (CO), but will receive and transmit a CO
alarm signal (with voice message) from an interconnected CO or combination smoke / CO alarm.
The carbon monoxide (CO) alarm pattern is four quick beeps with voice “Warning! Carbon Monoxide” repeating every
5 seconds. The red LED blinks in time with the alarm pattern only on the alarm(s) that detected the hazard (initiating
alarm). After 4 minutes in CO alarm the alarm pattern will only occur every 60s.
WARNING:
CARBON MONOXIDE (CO) IS A COLORLESS,
ODORLESS, POISONOUS GAS. YOU CAN’T TASTE, SEE, OR SMELL
CO, BUT IT CAN KILL IN JUST MINUTES. THIS ALARM WILL SOUND
IN A 4-BEEP PATTERN IF LIFE THREATENING LEVELS OF CO ARE
DETECTED. IF THE ALARM SOUNDS:
1
)
Immediately evacuate all occupants from the space and go outdoors to fresh air.
2) Call emergency responders (911 or fire department) for help; notify the building
or vehicle owner, as necessary.
EMERGENCY PHONE #: _______________________
Always consider a CO alarm to be dangerous. After emergency services responders have arrived, the premises has
been aired out, and your alarm remains in its normal condition, it is important to 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 problems are identified during this inspection, have the equipment serviced immediately. Note any
combustion equipment not inspected by the technician and consult the manufacturer’s instructions or contact the
manufacturer directly for more information about CO safety and this equipment. Make sure that motor vehicles are not
or have not been operating in an attached garage or adjacent to the residence.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

signal indicating the presence of low levels of CO. It’s designed to
prompt early awareness and action—allowing you to address the
issue before it escalates into a full alarm.
Even low levels of CO can pose health risks, particularly for individuals
with certain pre-existing medical conditions. Children, seniors, and
pets are also more susceptible and may begin experiencing symptoms
sooner.
Recommended actions:
1) Open windows to improve ventilation.
2) Attempt to identify and resolve the source of CO before an alarm is
triggered.
3) If you or a household member has a medical condition that could be
affected by the exposure of low CO levels (between 30 and 70 PPM),
consult your healthcare provider to understand any potential risks.
4) If the unit goes into full alarm, follow the Carbon Monoxide Alarm
Procedure outlined at the beginning of Section 15 for emergency
response and evacuation.

16. General Carbon Monoxide (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 of CO
Inside your home, appliances used for heating and cooking are the most likely sources of 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. Generators running in enclosed areas, such as
garages or living spaces, will create CO. CO can be produced when burning any fossil fuel: gasoline,
diesel, propane, natural gas, oil and wood. It can be produced by any fuel-burning appliance that
is malfunctioning, improperly installed, or not ventilated correctly, such as: Furnaces/boilers, 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, or a loose or cracked furnace heat
exchanger can also release CO into your building.
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/
boilers, 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 gases near the ground, car idling in an open or closed
attached garage, or near a home.
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 that the color of flame is blue on
pilot lights and burners. An amber or orange flame is a sign that the fuel is not burning completely
and may be releasing CO. Teach all household members what the alarm sounds like and how
33
to respond. Fire Departments, most utility companies and HVAC contractors will perform CO
inspections. Some contractors 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.
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 household:
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, cardio respiratory failure and 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
feeling 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.

17. Cleaning Your Alarm
Your Alarm Should be Cleaned at Least Once a Year
You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum
cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The
outside of the alarm can be wiped with a clean, dry cloth. Do not use water, detergents or cleaners as
they may damage the alarm.
NOTE: Do not insert fingers or cleaning items under the shield during cleaning.
If the alarm is in Fault mode, the alarm may be in need of cleaning. After cleaning, press the Test/Hush
button. If the fault does not clear, the alarm needs to be replaced.
• Never use detergent or other solvents to clean the unit.
• Avoid spraying air freshener, hair spray, or other aerosols near the alarm.
• Do not use a hair dryer to clean the alarm, as it may damage the alarm and impact performance.
• Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect
smoke (smoke only models) or smoke and CO (combination smoke/CO models).
• Never attempt to disassemble the unit to clean inside. This action will void your warranty.
35
For combination smoke/CO models:
The following substances can affect the CO sensor and may cause false readings and damage to the
sensor: Methane, propane, isobutane, iso-propanol, ethyl acetate, hydrogen sulfide, sulfide dioxides,
alcohol based products, paints, thinner, solvents, adhesives, hair spray, aftershave, perfume, and some
cleaning agents. Move the Alarm and place in another location prior to performing any of the following:
Staining or stripping wood floors or furniture
Painting
Wall papering
Using adhesives
Storing the unit in a plastic bag during any of the above projects will protect the sensors from damage.
When household cleaning supplies or similar contaminates are used, the area must be well ventilated.
WARNING:
REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS DETECTION.
36
18. Good Safety Habits
Develop and Practice a Plan of Escape
Prepare and practice a home escape plan twice a year, including drills at night. 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 re-enter under any circumstance!
• Make a floor plan indicating all doors and windows and at least two (2) escape routes from each
room. Stories above ground level may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire
and where to meet after they leave the house.
• 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.
• Familiarize everyone with the sounds of the smoke/CO alarm and train them to leave your home
when they hear it.
• Current studies have shown smoke/CO 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.
• 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.
37
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 smoke alarm pattern 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.
NFPA (National Fire Protection
Association)
Fire Safety in the Home: NFPA 72 is
intended to provide reasonable safety for
persons in family living units. Reasonable
fire safety can be produced through
the following three-point program: (1)
Minimizing fire hazards (2) Providing
fire-warning equipment (3) Having and
practicing an escape plan.
Smoke Detection – Are More 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 resident
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 attics (finished or unfinished), garages, or within 6 ft (1.8m) of a heating
or cooking appliance is not normally recommended, as these locations occasionally experience
conditions that can result in improper operation. *
* Reference National Fire Protection Association (NFPA) standard 72
For your information, the National Fire Protection
Association’s Standard 72 reads: Where required
by other governing laws, codes, or standards for a
specific type of occupancy, approved single and
multiple-station smoke alarms shall be installed as
follows:
1. In all sleeping rooms and guest rooms
2. Outside of each separate dwelling unit sleeping
area, within 21 ft (6.4 m) of any door to a sleeping
room, with the distance measured along a path
of travel
3. On every level of a dwelling unit, including
basements
4. On every level of a residential board and care
occupancy (small facility), including basements
and excluding crawl spaces and unfinished attics
5. In the living area(s) of a guest suite
6. In the living area(s) of a residential board and
care occupancy (small facility)
38
California State Fire Marshal
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.
