Wireless
Smoke Sounder
• Direct Plug with battery back-up
Thank you for purchasing a Kidde Wireless Smoke Sounder, 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. The Kidde Wireless Smoke Sounder provides an
additional warning for children, older adults, and individuals who may not wake to the sound
of a traditional smoke alarm. It also may be used to supplement a traditional smoke alarm
located in a caregiver’s bedroom, helping to insure that they respond to a fire emergency. The
Smoke Sounder combines with Kidde Wireless smoke alarms to create an interconnected system that links devices together so that when one smoke alarm sounds, it will trigger all units
to sound, 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.
Some of the features that are included in this unit are:
• Loud verbal warning: a recent study has shown that voice messages can be up to 61%
more effective in waking children.
• Low Frequency (1kHz) alarm signal: lower frequency signals may be more effective at
alerting those with high frequency hearing loss.
• Remote Hush
®
allows you to temporarily desensitize the initiating Kidde Wireless smoke
alarm (see section 4).
• Remote Push To Test prompts every Kidde Wireless device in your system to perform a selfdiagnos.Simply press the test button on any one of the Kidde Wireless units to activate (see
section 4).
• Low Battery HUSH allows you to stop the Smoke Sounder from producing a low battery
warning for up to twelve hours, in order to maintain your protection without having to
replace the battery at inconvenient times such as the middle of the night.
WARNING! This audible signaling device, model RF-SND, is NOT a smoke
alarm and has no means of sensing a fire hazard. This audible signaling
device MUST be used in conjunction with one or more operating Kidde
Wireless smoke alarms. The model RF-SND can only be used in conjunction
with Kidde RF-SM-ACDC A.C. wire-in or RF-SM-DC battery operated smoke
alarms. All Wireless units must be set to the same switch settings before they
are powered in order to work properly.
WARNING! DISCONNECTION OR LOSS OF AC POWER WILL LIMIT THE
OPERATING TIME OF THIS UNIT.

1. RECOMMENDED LOCATIONS FOR SMOKE SOUNDERS
• Child’s bedroom.
• Bedrooms of sound sleepers.
• An older adult’s bedroom.
• The bedroom of a person with high frequency hearing loss.
• In bedrooms without a smoke alarm and especially 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
• Caregiver’s bedroom as a supplement to a traditional smoke alarm.
2. LOCATIONS TO AVOID
• In an area that is obstructed by material or objects that may absorb sound and diminish
the Smoke Sounder’s effectiveness, such as an outlet behind drapes or furniture.
• Into an outlet that is connected to a switch.
• In direct sunlight to prevent discoloration of the plastic.
• In an area where the temperature may fall below 32ºF or rise above 100ºF, such as
garages and unfinished attics.
• In very humid areas.
• 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.
3. INSTALLATION INSTRUCTIONS
WIRELESS INTERCONNECT SETUP
1. Remove all 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 back cover (see Figure 1).
FIGURE 1
Dipswitch
3. Select one of the units. You will define the ID of your system by positioning the switch-
es of the dipswitch in a random pattern. The ID will need to be the same for each Kidde
Wireless device This ID will differentiate your alarm system from similar systems nearby.
Do not use the 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. Be careful to not get the sequence backwards.
5. Power each unit after setting the ID by installing the batteries. The devices only read the
ID that has been set when they are first powered. Any changes to the switches after the
unit is powered will not be recognized, and will require the power to be removed for a
minimum of 30 seconds before applying power again.
6. Push and hold the test button on each unit for at least 5 seconds, or until all devices
produce an alarm. If all units do not produce an alarm, refer to the trouble-shooting
section at the end of this user’s guide.
CAUTION: Due to the loudness of the device, always stand an arm’s length
away from the unit when testing.
7. Install the device in accordance with the user’s guide and repeat step 6. Since wireless
communication can be interrupted by a number of factors, you must test your alarms
system weekly to ensure proper communication between all units.
8. Read the user’s guide and keep it in a safe place for future reference.
If your Wireless smoke alarms and accessories 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.
BATTERY INSTALLATION
CAUTION! THIS UNIT WILL NOT FUNCTION PROPERLY WITHOUT A FRESH
BATTERY INSTALLED CORRECTLY. THIS DEVICE WILL QUICKLY DEPLETE
BATTERIES WHILE ON BATTERY BACK-UP. CONNECT THE UNIT TO AC POWER
IMMEDIATELY AFTER INSTALLING THE BATTERIES.
Remove the back cover from the unit by prying it up at the bottom in the center. If you are setting the unit up for the first time, set the Wireless ID as described previously before connecting
the battery. Connect the battery to the terminals in the back of the unit and place it in the battery compartment. Replace the back cover of the unit and place the unit in its chosen location.
WIRING REQUIREMENTS
• The appropriate power source is 120 Volt A.C. Single Phase outlet supplied from a nonswitchable circuit that is not protected by a ground fault interrupter.
WARNING: The Smoke Sounder 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 device.
