The Siren uses an LED light to indicate its status:

  • When the red light flashes continuously, the Siren is in pairing mode. You should follow the instructions in the Ooma Home Security app.
  • When the red light flashes twice, pauses, and repeats the sequence, the Siren is updating its firmware. You should wait for the update to complete.

In addition to the lights, the Ooma Siren also uses audible cues to communicate its status:

  • One beep every two seconds indicates one of the following statuses:
    • The device is in its arming grace period. You should make sure your doors and windows are secure and exit your home.
    • The device is in its alert grace period. You should use the app to prevent a false alarm or to take an action like calling 911.
  • One beep every second indicates one of the following statuses:
    • The device’s arming grace period is about to end. You should make sure your doors and windows are secure and exit your home.
    • The device’s alert grace period is about to end. You should use the app to prevent a false alarm or to take an action like calling 911.
  • A loud, continuous alarm indicates that the alert has been triggered. You should use the app to stop the false alarm or to take action like calling 911.
