1994 Zx Alarm

[markwade]

Hi all, my zx alarm seems to be playing up, it arms/disarms ok via the remote fob but if you deliberately set the alarm off the headlights flash but the alarm doesn't sound, I've tried disconnecting the battery to power reset the system but no joy. The siren does croak though when the battery is discon/recon, my questions are, is this a common prob with this alarm system? and how do I get to the siren to check connections etc, I think its in the drivers side front corner area but I blowed if I can find it!!, any help will be gratefully received. Cheers.
