What to do if my FBII Security System displays 'COMM FAILURE'?
- JJennifer ThomasAug 18, 2025
If your FBII Security System shows 'COMM FAILURE', it indicates a failure to communicate with the Central Station. This could be due to cut or disconnected telephone lines, requiring repair or replacement of the wiring. It may also indicate that the Central Station information is misprogrammed. Alternatively, the panel/dialer itself or the telephone lines could be faulty, in which case you should consider replacing the panel or consulting your local telephone company.
