Make Sure the Doors
and Windows Are Shut

The Alarm Contact Sensor connects to your Alarm Base Station and easily mounts to any door or window frame in your home. It sends you mobile alerts whenever your doors or windows open, so you’ll always be the first to know when something’s ajar.

  • Requires the Ring Alarm Security Kit
  • Triggers your Alarm when someones tampers with Contact Sensors
