how can i fix my accenta 8 mini aiarm?

As the alarm is trying to tell you, there's a "tamper fault" and until it is cleared, the alarm will not be useable. The strobe will continue flashing on the bell box until the fault is cleared.

Check for covers being moved on detectors/panel lid/bell box, or even damaged wires.

It might be worth getting the system professionally serviced.
