If the steps show in the ‘How do I fault-find a panel with no loudspeaker audio?’ points towards a defect with the panel please try the following checks.

Step-by-step guide


  1. If the test proves the fault is following the panel, enter the panel diagnostics and check if the panel controller board is receiving audio from the matrix. To enter the panel set-up menu, press and hold the menu button whilst rotating the panel encoder. Once in the Set-up menu select the Audio>Levels page. If you send audio to the panel, for example by an intercom call, you should see approximately 0 dB audio level on the ‘Main’ level meter.
  2. If test 1 shows no audio is present, remove the mains power to the panel, remove the set screws holding the rear cover and once the rear cover is removed check to see the loudspeaker cable is fully seated to the connector on the main board.
