This smoke alarm uses an extremely small amount of radioactive element in the ionization chamber
(see Section 9). Do not try to repair the smoke alarm yourself. Refer to the instructions in Section 12
for service.
• For mobile home installation, select locations carefully to avoid thermal barriers that may form at the
ceiling. For more details, see MOBILE HOME INSTALLATION below.
•When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm) from the side wall (see
Diagram A).
•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 Diagram A).
• 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). NFPA 72 states: “Smoke alarms in rooms with ceiling slopes greater
than 1 foot in 8 feet (.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 diagram “C”).

1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the bedrooms. Try to protect 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 protect 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 the alarm 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.

MOBILE HOME INSTALLATION
Mobile homes built in the past five to seven years have been designed to be energy efficient. Install
smoke alarms as recommended above (refer to RECOMMENDED LOCATIONS and Diagram A).
In 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 Diagram A).
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 Diagram B.
WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER R.V. 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 or rise above 100ºF.
•In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
•In very humid areas. 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 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.
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 must conform to article 760 of the U.S. National Electrical Code, NFPA 72
and/or any other codes having jurisdiction in your area.
• The appropriate power source is 120 Volt A.C. Single Phase supplied from a non-switchable circuit which is
not protected by a ground fault interrupter.
• The alarm should not be operated on power derived from a square wave, or modified square wave, inverter.
These power sources produce high peak voltages that will damage the alarm.
WIRING INSTRUCTIONS FOR A.C. 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 interconnect up to a total of
6 remote signaling devices and/or relay modules.
Caution! Kidde alarms and accessories CAN ONLY BE interconnected with other Kidde alarms and
accessories. Connection of these devices to another manufactures interconnect system, or connection with 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.
•When mixing models which have battery backup with models without battery backup, be advised that the
models without battery backup will not respond during an AC power failure.
•For more information about compatible interconnect units and their functionality in an interconnect system,
visit our web site at: www.KiddeUS.com
• The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet.
•Figure 1 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 (18 gauge or larger as required by local codes) available at all electrical supply stores and
most hardware stores.

CAUTION! THIS UNIT WILL NOT FUNCTION WITHOUT A PROPERLY INSTALLED BATTERY, AND IS EQUIPPED
WITH A BATTERY LOCKOUT FEATURE WHICH PREVENTS THE BATTERY CARRIER
FROM CLOSING IF A BATTERY IS NOT INSTALLED CORRECTLY.
MOUNTING INSTRUCTIONS
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
CAUTION: WHEN WALL MOUNTING: UNIT MUST BE MOUNTED SO
THAT BATTERY BOX FACES DOWN! (SEE FIGURE 1A)
1. Remove the trim ring from the back of the alarm by holding the trim
ring and twisting the alarm counter-clockwise.
2. After selecting the proper smoke alarm location as described in Section 1 and wiring the AC
Quick Connector as described in the WIRING INSTRUCTIONS, attach the trim ring to the electrical
box (see Figure 2). 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.
3. 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.
