Thank you for purchasing this smoke alarm. It is an important part of your family’s
home safety plan. You can trust this product to provide the highest quality safety protection. We know you expect nothing less when the lives of your family are at stake.
Kidde alarms and accessories CAN ONLY BE interconnected with other Kidde alarms
and accessories as well as specified brands and models of interconnect compatible
alarms. Connection of Kidde products to a non-specified manufacturer’s interconnect
system, or connection with non-specified equipment from another manufacturer into
an existing Kidde system could result in nuisance alarming, failure to alarm, or damage to one or all of the devices in the interconnect system. Refer to the User’s Guide
supplied with each Kidde product for interconnect compatible models, brands, and
devices. Refer to the wiring instructions in section 3 for NFPA initiating device limits.

1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the bedrooms. 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.
FIGURE 1
FIGURE 2 FIGURE 3
• Locate at least one alarm on every floor level.
• Locate an alarm in every sleeping room.
• 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.
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm)
from the side wall (see figure 1).
• When mounting the alarm on the wall, use an inside wall with the top edge
of the alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm)
below the ceiling (see figure 1).
• Put smoke alarms at both ends of a bedroom hallway or large room if the
hallway or room is more than 30 ft (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). 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” (see figure 3).
MOBILE HOME INSTALLATION
Modern mobile homes have been designed and built to be energy efficient.
Install smoke alarms as recommended above (refer to RECOMMENDED LOCATIONS and figures 1 and 2).
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 at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the
ceiling (see figure 1).
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 the alarm on an
inside wall. For minimum protection, install at least one alarm close to the bedrooms. For additional protection, see SINGLE FLOOR PLAN in figure 2.
WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER RV OR MOBILE
HOME VEHICLE HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT
LEAST ONCE A WEEK DURING USE.
2. LOCATIONS TO AVOID
• In the garage. Products of combustion are present when you start your automobile.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40ºF (4.4˚C) or rise above
100ºF (37.8˚C), such as garages and unfinished attics.
• In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
• In very humid areas (Greater than 85% R.H.). Moisture or steam can cause
nuisance alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (.9m) of the following: the
door to a kitchen, 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.
• Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is
desired, it should have an alarm silence feature or be a photoelectric type.
• Near fluorescent lights. Electronic “noise” may cause nuisance alarms.
• Smoke alarms are not to be used with detector guards unless the combination
(alarm and guard) has been evaluated and found suitable for that purpose.
3. INSTALLATION INSTRUCTIONS
WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. 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 appropriate power source is 120 Volt AC Single Phase supplied from a
non-switchable circuit which is not protected by a ground fault interrupter.
• WARNING: This alarm cannot be operated from power derived from a square
wave, modified square wave or modified sine wave inverters. 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 interconnected, all interconnected units must be powered
from a single circuit.
• A maximum of 24 Kidde 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, heat, carbon
monoxide, etc.). With 18 alarms interconnected, it is still possible to intercon-
nect up to a total of 6 remote signaling devices and/or relay modules.
• When mixing models which have battery backup (i12040, i12040A, i12060,
i12060A, i12080, i12080A, i12090A, i4618, i4618A, i5000, 1275, 1276,
1285, 1296, PE120, PI2000, PI2010, KN-COSM-IB, RF-SM-ACDC, KN-COPE-I,
KN-SMFM-I, HD135, KN-COB-IC, KN-COP-IC) with models without battery
backup, (1235, i12020, i12020A, KN-COSM-I SM120X, CO120X SL177I) be
advised that the models without battery backup will not respond during an
AC power failure.
• The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet.
• Figure 4 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 UL listed household wire (as required by local codes) available at all electrical supply stores and most hardware stores.
