Hi everyone, hopefully someone can help me.

My alarm went off at 4am this morning, i can't do anything to stop it, the fobs do nothing. Is there another way to disarm. It starts and runs perfectly but the alarm system does nothing. The battery seems fine and I have searched the forums but cant find the answer.
If anyone can help that will be great

I found the siren and stopped it for now, so off to TVR Garage to get it fixed. I still have no idea whats wrong with it though.
