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.
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 12. 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.
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 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!
NOTE: See Section 12. RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

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.
This alarm is not intended to alert hearing impaired individuals.

10
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.

11
7. Recommended Locations for Smoke 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 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.

NFPA 72 states: “Smoke alarms in rooms with
ceiling slopes greater than 0.3 m in 2.4m (1ft in 8 ft)
horizontally shall be located on the high side of the
room.” NFPA 72 states: “A row of detectors shall be
spaced and located within 0.9 m (3 ft) of the peak of
the ceiling measured horizontally.”

•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
10 cm (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 (30 ft) long.
•Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 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.

13
8. Locations to Avoid
•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.

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.
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.

•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 10-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.
If you are installing for wireless interconnect function, and have not yet setup your wireless alarm
network, do not connect your wireless unit to the AC quick connect harness or mounting bracket yet. Go back
to Section 9: ACTIVATION AND WIRELESS ALARM NETWORK. If you are not using the wireless interconnect
function, or if you have finished wireless alarm setup, then proceed with the following three steps.
•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: Wireless units will emit a series of LED blinks, tones, and voices as the unit(s) search for a wireless
alarm network. If you are intending to use wireless units without the wireless function, ignore these
notifications, and the wireless function will turn off in about 15 minutes. You can turn the wireless
function on again at a later date if desired. See Section 9.2.
NOTE: Attaching AC power first, without rotating the alarm onto the mounting bracket, will result in a low
battery trouble condition chirp and voice message saying, “Replace Alarm” (see Troubleshooting Guide).
You need to activate the battery to eliminate the low battery trouble condition chirps and voice message.
Attach unit to mounting bracket very soon after applying AC power to avoid false low battery notification.
