S90 Siren Communication Fault

I had something similar with my S90. I wouldn't jump to conclusions about the cable just yet. Does the central locking still work?

Central locking is functioning normally. What was the outcome in your case?

Ah, that's different then. In my case, the central locking went haywire at the same time. If it is just the alarm, it may well be the siren unit itself. I would recommend taking it to a workshop to check the alarm controller.

Thanks. As suspected, it was a faulty connector. Repair cost 95€. Alarm system is up and running again.
