1. Smoke Alarm: What To Do When the Alarm Sounds
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 alarm pattern, and the Strobe flashes every second.
The smoke alarm takes precedence when both smoke and carbon monoxide are present.
•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.
•Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or
picking up valuables.
•In 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 from your cell phone outside, or from your neighbour’s home—not from yours!
•Don’t return to your home until the fire officials say that it is all right 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:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
NOTE: See Section 11. RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

2. Carbon Monoxide Alarm: What To Do When the Alarm Sounds
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 alarm pattern. The Strobe will flash 4 times every 5 seconds.
warning: Carbon monoxide alarm aCtivation indiCates the presenCe
of Carbon monoxide (Co) at high ConCentrations whiCh Can kill you.
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 or 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 activation of the
alarm!

6. 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.
•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.
•Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to
help insure maximum 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 (This model has a sealed backup battery).
•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, walls, on roofs, on the other side of a closed door or on a different
floor.
•If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
•The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For maximum
protection, a smoke alarm should be installed in each sleeping area on every level of a home.

11
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•IMPORTANT: This alarm is designed to detect carbon monoxide gas from ANY source of combustion. It is
NOT designed to detect any other gas.
CAUTION: This alarm 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!
•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.
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. IT IS NOT SUITABLE FOR INSTALLATION IN HAZARDOUS LOCATIONS
AS DEFINED IN THE LOCAL BUILDING CODE. IT IS NOT DESIGNED FOR USE IN A RECREATIONAL
VEHICLE RV OR BOAT.
•The installation of this device should not be used as a substitute for proper installation, use, and
maintenance of fuel burning appliances, including appropriate ventilation and exhaust systems.
•This alarm does not prevent CO from occurring, nor can it solve any existing CO problem.
WARNING: THIS DEVICE IS DESIGNED TO PROTECT INDIVIDUALS FROM ACUTE EFFECTS OF
CARBON MONOXIDE EXPOSURE. IT MAY 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.
•This alarm has not been investigated for carbon monoxide detection below 70 PPM.
•This combination smoke and carbon monoxide alarm requires a continuous supply of electrical power –
it will not work without power.

12
7. Recommended Locations
•For rooms larger than 250 sq. ft. the notification device should be located within 4.88 m (16’) of the pillow when located in
a sleeping area.
•Locate the first strobe/smoke alarm in the bedroom in which the hearing impaired individual sleeps. Try to monitor the exit
path, as the bedrooms are usually farthest from the exit. Locate the first alarm in the immediate area of the bedrooms. If
more than one sleeping area exists, locate additional alarms in each sleeping area (Figure 7-B).
•Locate additional strobe lights or combination smoke/strobe alarms in any lived-in room where a hearing impaired
individual would need to be notified of an alarm condition.
•Locate additional alarms to monitor any stairway as 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 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 an alarm on the ceiling, locate it at a minimum of 10 cm (4") from the side wall.
•When mounting 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 30.5 cm (12") below the ceiling.
•Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more than 9.1 m (30ft) long.
•Install Smoke Alarms on sloped, peaked or cathedral ceilings no closer than 0.9m (3 ft) of the highest
point (measured horizontally).
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 on the previous page. 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 minimum of 10 cm (4”) and a maximum of 30.5 cm (12”) 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. For minimum
protection install at least one alarm close to the bedrooms.
WARNING: TEST YOUR ALARM OPERATION AFTER MOBILE HOME HAS BEEN IN STORAGE OR
UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.

15
8. Locations to Avoid
•Do not place in direct sunlight or install near high ambient light areas; the bright light may reduce one’s
ability to notice the strobe light.
•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 or be a photoelectric type.
•Do not install within 1.8 m (6 ft) of heating or cooking appliances.
•Less than 10cm (4”) from the peak of an “A” frame type ceiling.
•In an area where the temperature may fall below 4.4°C (40°F) or rise above 37.8°C (100°F), such as garages
and unfinished attics.
•In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
•In very humid areas (above 95% RH, non-condensing). Moisture or steam can cause nuisance alarms.
•In insect-infested areas.
•Smoke alarms should not be installed within 0.9m (3ft) 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 electronics may cause nuisance alarms.
•Do not install near vents, flues, chimneys or any forced/unforced air ventilation openings.
•Do not install near fans, doors, windows or areas directly exposed to the weather.
•Do not obstruct the vents located on the alarm. Do not place the alarm where drapes, furniture or other
objects block the flow of air to the vents.

9. Wiring Instructions
WIRING REQUIREMENTS
•This alarm should be installed on a CSA-Listed or recognized junction box. All connections should be
made by a qualified electrician and all wiring used shall be in accordance with codes having jurisdiction
in your area. The multiple station interconnect wiring to the alarms must be run in the same raceway or
cable as the AC power wiring. In addition, the resistance of the interconnect wiring shall be a maximum
of 10 ohms.
•The appropriate power source is 120 V AC Single Phase, supplied from a non-switchable circuit, which is
not protected by a ground fault interrupter.
•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.
•If only one CO alarm is installed, confirm it can be heard from all sleeping areas.
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.
WIRING INSTRUCTIONS FOR AC QUICK CONNECT HARNESS
CAUTION: Turn off the main power to the circuit before wiring the alarm.
•For alarms that are used as single station, DO NOT CONNECT THE RED WIRE TO ANYTHING. Leave the
red wire insulating cap in place to make certain that the red wire cannot contact any metal parts or the
electrical box.
•When alarms are hardwire interconnected, all interconnected units must be powered from a single circuit.

17
•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.). With 18 alarms interconnected, it is still possible to
interconnect up to a total of 6 remote signaling devices and / or relay modules.
•The maximum wire run distance between the first and last unit in an
interconnected system is 305 m (1000 ft).
•Figure 9-A 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-Listed household wire (as required
by local codes) available at all electrical supply stores and most
hardware stores.
NOTE: AC power should be turned off at this stage.

•After selecting the proper location for your Alarm, and wiring the AC QUICK CONNECT harness as
described in the WIRING INSTRUCTIONS, attach the mounting bracket to the electrical box. To ensure
aesthetic alignment of the alarm with the hallway, or wall, the “A” line on the mounting bracket must be
parallel with the hallway when ceiling mounted, or horizontal when wall mounted.
•Pull the AC QUICK CONNECTOR through the center hole in the mounting bracket and secure the bracket,
making sure that the mounting screws are positioned in the small ends of the keyholes before tightening
the screws.
•Plug the AC QUICK CONNECTOR into the wiring harness attached to the unit, making sure that the locks
on the connector snap into place. Then push the excess wire back into the electrical box through the
hole in the center of the mounting bracket.
•Install the alarm fully on the mounting bracket by rotating the alarm in a clockwise direction.
NOTE: The alarm will mount to the bracket in 4 positions (every 90 degrees).
NOTE: Installing the alarm on the mounting bracket will automatically activate the battery backup.
•Turn on the AC power. The green AC Power On Indicator should be lit when the alarm is operating from AC
power.
NOTE: Attaching AC power first, without rotating the alarm onto the mounting bracket, will result in a
false low battery trouble condition chirp and voice notification (see Troubleshooting guide). You need to
activate the battery to eliminate the false low battery trouble condition chirps and voice. Attach unit to
mounting bracket very soon after applying AC power to avoid false low battery notification.
NOTE: The battery activation is a one-time feature. After activation, the battery cannot be turned off,
and can only be discharged at the end of unit life. If the alarm is removed from the mounting plate, the
backup battery will remain active. See Permanently Disable Alarm / Discharge Battery section.
The alarm is now activated! After installation / activation, test your alarm as described in Operation and
Testing section.
WARNING: FAILURE TO PROPERLY INSTALL AND ACTIVATE THIS ALARM WILL PREVENT PROPER
OPERATION OF THIS ALARM AND WILL PREVENT ITS RESPONSE TO FIRE HAZARDS.

10. Operation and Testing
OPERATION
The alarm is operating once it is activated and testing is complete. When products of combustion (smoke or
CO) are sensed, the unit sounds a loud alarm with Strobe flashing and 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.
LANGUAGE SELECTION
This unit operates in either English or French. At initial power up, the unit will default to English, and announce
“English Language selected - Pour française appuyer 2 fois sur le bouton.”
To switch your language preference at any time, press the Test button twice on ALL devices you wish to connect.
You should hear one beep for each button press, followed by a voice message confirming your language selection.
If French is selected, the unit will announce “Langue française selectionné - For English, press button twice.”

TESTING
Test your alarm weekly by pressing and releasing the test button (dome) quickly. A quick beep will confirm the
button has been pushed followed by voice prompts that will inform you of the upcoming test sequence. See
Other Alarm Visual and Audible Indicators table.
The alarm, strobe, and voice (and any interconnected units) will activate if the electronic circuitry, horn,
speaker, and battery are working. If the alarm, strobe, or voice does not activate, or gives erratic or low
volume sound, the unit must be replaced. NOTE: AC power must be applied for the strobe to activate.
See Permanently Disable Alarm / Discharge Battery section to determine how to prepare the unit for
shipment or disposal.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 0.7 M 2.5 FT AWAY
FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING, AND AVOID LOOKING AT THE BRIGHT
STROBE DIRECTLY, OR COVER IT WITH YOUR HAND.
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.
STROBE SYNCHRONIZATION
This strobe alarm will automatically synchronize (flash at the same time) with other P4010ACLEDxx strobes that
are part of the interconnected system. Synchronization will take up to 20 seconds when in alarm.
NOTE: THE ALARMS WILL NOT SYNCHRONIZE DURING TEST MODE.
SMOKE/CO ALARM MEMORY
If a unit experiences a smoke or CO alarm event, then the condition clears and the unit stops alarming, the
unit will give a visual (LED) indicator that a previous alarm has occurred within the last hour. See the Other
Alarm Visual and Audible Indicators table.
