Wireless
Smoke Alarm
• Hardwire with battery back-up
Thank you for purchasing a Kidde Wireless AC Powered Smoke Alarm, part of the
Kidde Wireless System. It is an important part of your family’s home safety plan. You
can trust this product to provide the highest level of quality and performance. We
know you expect nothing less when the lives of your family are at stake. This alarm, in
combination with other Kidde Wireless products, provides you with an interconnected
alarm system without having the inconvenience or extensive labor of rewiring your
home. An interconnected alarm system provides an earlier warning to smoke or fire by
linking alarms so that when one unit sounds, it will trigger all other units to sound,
thereby giving a family more time to escape. Kidde estimates that nearly 100 million
U.S. homes either do not have interconnected smoke alarms, or have limited coverage.
For homes that do have interconnected systems, this battery powered alarm can provide additional fire protection in other areas of the home.
Some of the features that are included in this unit are:
• Smart HUSH
TM
feature allows you to quiet your alarm while taking care of a non-
emergency event (see section 4).
• Remote HUSH
®
feature allows you to temporarily desensitize the initiating Kidde
Wireless alarm from any Kidde Wireless unit (see section 4).
• Remote Push To Test prompts every Kidde Wireless device to perform a self-diagnosis. Simply press the button on any Kidde Wireless unit to activate(see section 4).
• Internal timer reminds you to replace your unit after 10 years to ensure the most
reliable protection (see section 6).
• Low Battery HUSH
®
feature allows you to stop the smoke alarm from producing a
low battery warning for up to twelve hours in order to maintain protection without
having to replace the battery at inconvenient times.
NOTE: To expand the coverage of your home’s current Hardwire with Interconnect
smoke alarm system, replace ONLY ONE of the hardwired alarms with a Kidde Wireless
AC Powered Smoke Alarm. Never connect two as doing so will result in the wireless
alarms triggering each other. They will not stop alarming until one is disconnected
from the electrical circuit. If your home has Hardwired alarms that are NOT interconnected, you can create an interconnected system by replacing each of the home’s
smoke alarms [up to 12] with a Kidde Wireless AC Powered Smoke Alarm.

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 they act as chimneys for smoke and
heat.
• Locate at least one alarm on every floor.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances operate (i.e. portable heaters
or humidifiers).
• Locate an alarm in every room where someone sleeps with the door closed. The closed
door may prevent a sleeping individual from hearing an alarm that is not inside the bedroom. Kidde recommends installing a Wireless Smoke Sounder in all rooms where older
adults, individuals with partial hearing loss, and children sleep.
• Smoke, heat, and combustion products rise to the ceiling and spread horizontally.
Mounting the smoke alarm in the center of the ceiling 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 below.
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm) from the
sidewall (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 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 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 Figure 1. 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 that 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.

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, such as
garages and unfinished attics.
• In dusty areas. Dust particles may cause nuisance alarm or a 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 supply ducts used
for heating or cooling, ceiling paddle 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, amateur radios, electrical equipment or other devices known to
transmit in the RF band. Electronic “noise” may cause nuisance alarms.
• Near large metal surfaces and bundles of wire.
Smoke alarms are not to be used with detector guards unless the combination (alarm and
guard) have been evaluated and found suitable for that purpose.
3. INSTALLATION INSTRUCTIONS
WIRELESS INTERCONNECT SETUP
1. Remove your new Kidde Wireless Interconnect devices from their respective packages
and place them in front of you.
DO NOT PLUG THEM IN OR INSTALL THE BATTERIES.
2. Find the 8-position dipswitch located on the back
of each device. For this model, the dipswitch is
located under the battery door (see Figure 4).
3. Select one of the units. You will define the ID of
your system by positioning the switches of the
dipswitch in a random pattern. The ID will need
to be the same for each alarm or accessory. This
ID will differentiate your alarm system from similar systems nearby. DO NOT USE THE DEFAULT ID
YOUR UNITS ARE SHIPPED WITH!
4. Using a pen or pencil, change the switches in each of the Kidde Wireless devices to
match the pattern you selected in step 3. Ensure that the sequence is not reversed.
5. Power each unit after setting the ID by installing the batteries. The alarms only read the
ID that has been set when they are first supplied power. Any changes to the switch
after the unit is powered will not be recognized, and will require the power to be
removed for a minimum of 30 seconds before powering again.
6. Push and hold the test button on each unit for at least 5 seconds, or until all the devices
produce an alarm. If all the units do not produce an alarm, refer to the trouble-shooting
section at the end of the user’s guide.
FIGURE 4
CAUTION: Due to the loudness of the alarm, always stand an arm’s length
away from the unit when testing.
7. Install the alarms in accordance with the user’s guide as described in section 1, and
repeat step 6. Since wireless communication can be interrupted by a number of factors, you must test your alarms weekly to ensure proper communication between
alarms.
8. Read the user’s guide and keep it in a safe place for future reference.
If your Wireless smoke alarms enter alarm mode, first check to see if there is a fire.
If a fire does not exist, and the test buttons have not been activated on any of the
units, it is likely that you are receiving interference from a similar system nearby. In
this case, repeat the above steps and select a different dipswitch pattern, making
sure to disconnect power and remove the batteries before changing the switch
positions.
WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. listed or recognized junction box. All con-
nections 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 AC Single Phase supplied from a non-switch-
able circuit that is not protected by a ground fault interrupter.
WARNING: This alarm cannot be operated on power derived from a square wave or modified square 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
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING THE
ALARM.
• If you are using the Kidde Wireless AC Powered alarms to replace Hardwired alarms that
are not interconnected (see definitions on Quick Setup Guide), 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.
• Only one Wireless AC Powered alarm may be used when all existing alarms are
Hardwired with Interconnect (see definitions on Quick Setup Guide).
• A maximum of 24 devices may be hardwire interconnected in a multiple station arrange-
ment. 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.
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 intercon-
