Hi,
Managed to get it working after finding another forum with the same issue and an avanti panel. Bellbox passes all tests.
However, since trying to get bellbox connected, cannot get the Tamper light to turn off. Tried engineer reset, factory reset, checked all connections but no joy.
Everything was fine and no warning lights until attempted to connect bellbox. Even with the bellbox disconnected, cannot reset tamper.
Have rechecked all wiring and fuses.
Any ideas?
