The Alarm Range Extender is the perfect solution for larger homes. It extends the network signal from your Ring Alarm Base Station to your Alarm Contact Sensors, Motion Detectors and Keypads so you will always have a reliable connection. This will help ensure that all your Ring Alarm components stay online and avoid disconnecting from the internet. It is easy to install and plugs into any standard power outlet. And it also comes with a 24-hour backup battery, so even if your power goes out, your Extender will still be active.
