Im having problem with my alarm.

I notice when I drove this morning that the indicater lamp was active (blue). I thought I have forgotten to close any door, that wasent the problem.

The alarm is not working, only the central locking system and that works over the alarm. All the fuses are intact. All the doors indicaters are working too. Is it possible the alarm has broken? I fitted it for about seven month ago.

Its a cheap alarm (Thor).
