A Ring Alarm Contact Sensor protecting a window inside a modern home.

Troubleshooting Tampered Contact Sensors

Installed on windows and doors, Contact Sensors monitor when someone enters the home or opens a window. If the Contact Sensor is triggered, the alarm will siren, a notification will be sent to you via the Ring app, or both depending on your personal settings.

When a sensor has been removed or adjusted in some way, the tamper switch provides an added layer of security by triggering your Alarm to siren and prompting the Tampered Indicator to notify you in the app that the sensor has been tampered with.
