Anyone know where the alarm/siren is located on 1998 C180?

Does anyone know where the alarm/siren is located on a 1998 C180 Mercedes. From 1998 they were factory fitted and it is somewhere in the engine bay. It was disabled by the AA as it kept going off as the battery was u/s. It now has a new battery and I have put the fuse back and the alarm is operational, but I can't locate the sounder, so indicators flash, but no audible.
