Safe checks you can try first

  1. Separate the symptom: no ring, no audio, or no door release.
  2. Test whether other apartments or users have the same problem.
  3. Listen for a buzz, click or silence at the door release.
  4. Do not force the electric strike or leave the entrance unsecured while testing.

When to call: Call when the buzzer stays silent, only some stations work, or the door release does not respond consistently.
