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 sys-
tem 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
®

smoke alarm (see section 4).
• Remote Push To Test prompts every Kidde Wireless device in your system to perform a self-
diagnos.Simply press the test button on any one of the Kidde Wireless units to activate (see
section 4).
• Low Battery HUSH® feature 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 hav-
ing to replace the battery at inconvenient times.
