REMOVABLE.

After installation TEST your Smoke Sounder by following the test procedure outlined in section 4.

Kidde alarms and accessories CAN ONLY BE interconnected with other Kidde alarms and accessories as well as speci-

fied brands and models of interconnect compatible alarms. Connection of Kidde products to a non-specified manufac-

turer’s interconnect system, or connection with non-speci- fied 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 User’s Guide supplied with each Kidde product for lists of interconnect compatible models, brands, and devices.

4. OPERATION AND TESTING

OPERATION

The Smoke Sounder is operating once fresh batteries are installed, it is plugged into a non- switched AC outlet and testing is complete. When the Smoke Sounder receives an alarm message from a Kidde Wireless smoke alarm, the horn will sound a loud temporal alarm for two cycles of three beeps followed by a verbal “Danger” message. This cycle repeats until the alarm message is no longer broadcasted from the smoke alarm.

Remote HUSH®: Press the button on any Kidde Wireless device to activate the Smart HushTM on the Wireless smoke alarm that is initiating an alarm (see your Wireless smoke alarm’s user’s guide for an explanation of Smart HushTM). This allows you to enable the Smart HUSH™ feature on a Kidde Wireless smoke alarm that may be installed in an area that is difficult to reach. This feature should only be used when a known alarm condition, such as smoke from cooking, activates the alarm.

CAUTION: BEFORE USING THE REMOTE HUSH® FEATURE, IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.

Low Battery HUSH®: When the battery needs replacement, the unit will produce a low bat- tery “chirp” once per minute and announce “low battery”. The Low Battery HUSH® allows you to press the button on the unit producing the warning, and disable the “chirp” for a period of up to 12 hours. This gives you a chance to replace the battery at a more conven- ient time without sacrificing your safety by disconnecting the sounder from power. During this Low Battery HUSH® period, your Smoke Sounder is performing normally.

LED Indicator Operation

Red LED:

The red LED will flash in conjunction with the unit beep. Therefore, the red LED will flash during a smoke alarm, a low battery mode chirp and a unit error mode chirp.

Green LED:

The green LED will illuminate as described below under the following conditions: STANDBY CONDITION (powered by AC and battery backup) - The LED will be con- stantly on.

STANDBY CONDITION (powered by only battery backup) - The LED will flash every 10 seconds.

RF-SND specifications

The Kidde RF-SND is a sophisticated combination smoke and carbon monoxide (CO) alarm that integrates advanced features and technologies to enhance home safety. As a vital addition to household safety systems, it employs cutting-edge sensing technologies designed to provide reliable protection against both smoke and harmful carbon monoxide emissions.

One of the standout features of the Kidde RF-SND is its dual-sensor capability. The alarm utilizes a photoelectric sensor to detect smoke from slow-burning fires, such as those caused by smoldering furniture, while its ionization sensor efficiently responds to fast-burning fires, such as those generated by paper and flammable liquids. This dual approach significantly improves the alarm’s ability to accurately identify different fire types and reduces the likelihood of false alarms, ensuring that users receive timely alerts when it matters most.

The RF-SND also incorporates a high-performance carbon monoxide sensor, which continuously monitors CO levels in the home. This feature is crucial, as carbon monoxide is a colorless, odorless gas that can be deadly in high concentrations. The RF-SND activates when CO levels surpass a predetermined threshold, giving inhabitants essential time to react and evacuate.

A notable characteristic of the Kidde RF-SND is its wireless interconnectivity feature, which allows multiple alarms to communicate with each other. When one unit detects smoke or CO, all interconnected alarms sound, providing an early warning throughout the house. This is particularly beneficial for larger homes, as it ensures that alerts are heard regardless of where they originate.

Powering the Kidde RF-SND is an easy-to-change battery system, ensuring continuous operation without the hassle of hardwiring. Additionally, the unit is equipped with a voice alarm feature that announces the type of danger detected, whether it’s smoke or carbon monoxide, allowing homeowners to make informed decisions during emergencies.

The Kidde RF-SND model is also designed with user-friendly installation in mind. Its compact, modern design fits seamlessly into any home decor, and included installation materials make setup straightforward. Users can easily test and silence the alarm with a single button, further enhancing the overall convenience.

In summary, the Kidde RF-SND combines advanced sensing technologies, wireless interconnectivity, and user-centric features, making it a comprehensive solution for fire and carbon monoxide safety in homes. Its ability to provide critical alerts and protect lives is paramount, solidifying its place as a trusted device in residential safety.
