Expand your Ring Alarm security system and let the neighborhood know that you are taking care of the protection of your entire home. With an adjustable volume siren and flashing LED lights, the outdoor siren can help others quickly identify your home in an emergency. The "Sunset to Sunrise" feature allows you to control the lighting of the Ring logo through the Ring app. When activated, your outdoor siren visibly signals to your neighborhood, even in the dark, that you are protecting your home. To use "Sunset to Sunrise," your Ring Alarm outdoor siren must be powered continuously with a quick-change battery pack along with a solar panel for permanent charging, or hardwired. Alternatively, you can connect the outdoor siren to a Ring power supply (2nd generation) to a standard indoor outlet.
