Troubleshooting Ring Alarm Outdoor Contact Sensor (2nd Gen)

Follow these steps to help resolve issues with your Ring Alarm Outdoor Contact Sensor (2nd Gen).

See troubleshooting tips for tampered Contact Sensors

For all Outdoor Contact Sensor troubleshooting steps, make sure your sensor is within three to five feet of the Base Station.

The light patterns on your Outdoor Contact Sensor will help you identify if it’s working well, or if there’s something wrong. The LED indicator on your Outdoor Contact Sensor might:

• Blink green three times

  when it is ready to connect to the network.
• Blink green one time

  when it is connected and communicating with your Base Station.
• Blink red one time

  when it is unable to communicate with the Base Station.

Try these steps, one at a time, and see if any of them resolve the issue before moving on to the next step. If the light flashes green one time, it is back online and working.

• Move the Contact Sensor closer to the Alarm or Alarm Pro Base Station.
• Add a

  Range Extender

  between the Contact Sensor and the Base Station. The Range Extender helps extend and expand the Base Station’s Z-Wave network, allowing for greater range and signal strength for all compatible devices at your location.
• Remove the back cover, remove all batteries, wait a few seconds, then reinsert them.
• If nothing works and there is no light on the Outdoor Contact Sensor, try replacing the batteries with new ones.

If your Contact Sensor isn’t working or being recognized by your Ring Alarm and the battery power is sufficient, you may have to adjust the position of the magnet and sensor. Move the sensor closer to the magnet or in a more optimal alignment. View tips for installing a Contact Sensor.
