I'm alarmed.

Hello guys, further to my previous threads regarding the alarm siren for my 2005 3.0 td6, I have purchased a used alarm siren and, fitted it. The alarm siren appears to work but, emits what I can only describe as a weak beep, beep, beep sound. I was expecting a more robust alarm siren sound. Is this the standard alarm sound?. Many thanks, Andy

If the alarms going off its probably already too late innit so what's the point of a loud alarm? Immobiliser and tracker much more worthwile

clean the conectors up, or buy a new one
