1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps, 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).
•Alert small children in the home as well as anyone else that might have difficulty recognizing the impor-
tance 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.
•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.

2. Carbon Monoxide Alarm: What To Do When The Alarm Sounds
NOTE: This is not a carbon monoxide (CO) alarm, but will receive and transmit a CO alarm signal from an
interconnected CO or combination smoke/ CO alarm.
The carbon monoxide (CO) alarm pattern is four quick beeps repeating every 5 seconds.
WARNING: ACTUATION OF YOUR CO ALARM INDICATES THE PRESENCE OF CARBON MONOX
IDE CO WHICH CAN KILL YOU. IF THE ALARM SIGNAL SOUNDS:
1 Operate the Test/Hush® button. NOTE: Pressing the button on the initiating CO or combination smoke/CO
unit in your system will silence the alarm notification, including all interconnected units. If the CO or combina-
tion smoke/CO unit goes into alarm mode again within six minutes, it is sensing high levels of CO which can
quickly become a dangerous situation.
2 Call your emergency services (Fire Department or 911). EMERGENCY PHONE #:__________________
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. 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.
Do not reenter the premises or move away from the open door/window until the emergency services respond-
ers have arrived, the premises have been aired out, and your alarm remains in its normal condition.
4 After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified
appliance technician to investigate sources of CO from fuel burning equipment and appliances, and to inspect
for proper operation of 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 the equipment. Make sure that motor vehicles are not, or have not
been, operating in a garage attached or adjacent to the residence. Never restart the source of a CO problem until it has
been corrected. Never ignore the sound of the alarm! NOTE: See Section RECOGNIZING NUISANCE ALARMS, for
nuisance alarm situations.

6. Limitations Of Smoke 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.
•For maximum detection of the various types of fires that can occur within the home, including fast flaming and slow
smoldering, it is recommended that multi criteria smoke alarms be installed. This model meets the latest residential
smoke alarm standards, which includes enhanced resistance to nuisance alarms from cooking.
•A battery powered alarm must have a battery of the specified type, in good condition and installed properly (this
model has a replaceable 9V 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, within walls, on roofs, on the other side of a closed door or other obstruction.
•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
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 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.

NFPA 72 states: “Smoke alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in 2.4 m) horizontally
shall be located on the high side of the room.” NFPA 72 states: “A row of detectors shall be spaced and located
within 3 ft (0.9m) of the peak of the ceiling measured horizontally.”
Figure 7-B Figure 7-C

•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 30
feet (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).
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 recom-
mended 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.

13
8. Locations to Avoid
(See Figures 7-A, 7-B, & 7-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 of cooking appliances.
•Do not install within 6 ft 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 40ºF or rise above 100ºF, 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 (.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.
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.

14
9. Wiring / Installation / Activation
NOTE: To avoid false low battery chirping pull out the battery
pull tab first, before connecting AC power.
Wiring Requirements
•This alarm should be installed on a UL Listed or recognized
junction box.
All connections should be made by a qualified electrician and all wiring used shall be in accordance with
articles 210 and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other 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 maximum wire run distance between the first and last unit in an interconnected system is 1000 feet.
•The appropriate power source is 120 Volt AC Single Phase supplied from a non-switchable circuit.
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 Connector 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 (see below for details on interconnecting Kidde devices).
•Figure 9-B 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.
•For best results to minimize nuisance alarms, interconnected alarms should be on a dedicated line. If not on a dedicat-
ed line, it is suggested that the smoke alarms share a lighting load circuit that does not have a dimmer associated with
it. If receptacles must be placed on the same line it is suggested that they be placed ahead of the smoke alarms (see
Figure 9-C). This will prevent large voltage drops from occurring between the first and last alarm in the circuit.
NOTE: Use standard UL 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 CONNECTOR harness
as described previously, 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 should be
parallel with the hallway when ceiling mounted,
or horizontal when wall mounted.
•Pull the AC QUICK CONNECTOR through the cen-
ter 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 back
of 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).
•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 pulling the battery pull tab, will result in a false low battery
trouble condition (see Troubleshooting Guide). You need to activate the battery to eliminate the false low
battery notifications. Pull the battery pull tab before, or very soon after applying AC power to avoid false
low battery notification.

10. Operation And Testing
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). When products of
combustion (smoke) are sensed, the unit sounds a loud alarm. See Sections 1 and 2 for alarm signal descriptions.
Testing
Test your alarm weekly by pressing and releasing the button quickly. A quick beep will confirm the button has
been pushed followed by the test sequence. See Other Alarm Visual and Audible Indicators table. The alarm
(and any interconnected units) will sound if the electronic circuitry, horn and battery are working. If the alarm
does not sound, or gives erratic or low volume sound, the unit must be replaced.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 2.5 FEET 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.
Chirping
When End of Unit Life or Low Battery chirping begins, you can temporarily silence these chirps by pressing
the button. See Troubleshooting Guide.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE MODE.

20
11. Recognizing Nuisance Alarms
Smoke Nuisance
HUSH®: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation, you
can push the button on the initiating unit 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® period, the smoke alarm will automatically
reset and sound the alarm if particles of combustion are still present. You can use Hush® repeatedly until the air
has been cleared of the condition causing the alarm.
NOTE: Dense smoke will override Hush® 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 discov-
ered, get out and call the fire department or 911.
This alarm is designed to minimize nuisance alarms. 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
WARNING: THIS UNIT DOES NOT DETECT CO, BUT IT WILL RECEIVE AND TRANSMIT A CO
ALARM SIGNAL FROM AN INTERCONNECTED CO OR SMOKE/CO COMBINATION ALARM. IT IS
IMPOSSIBLE TO DETERMINE THE SOURCE OF A CO ALARM USING SIGHT OR SMELL. ALWAYS CON
SIDER A CO ALARM EVENT AS DANGEROUS.
•Pushing the button on the initiating CO or Smoke/CO combination alarm will silence that alarm and all
compatible interconnected units.
•Pushing the button on any hard-wire smoke alarm will do nothing to silence an interconnected CO alarm.
