I have been trying to source a 4 zone expander, Scantronic part no 9124, but without success. I have been keeping an eye in Ebay and in fact (as recommended via a previous posting here) purchased a 4 zone expander board which had been advertised as suitable for Scantronic 6000 + 9100 systems...
Thank you for the help and information. Very much appreciated.
Re the Strobe connections, if I wire directly to the panel ('Aux-' & 'Strobe No') as shown on the wiring diagramme, do I need to add the single core link from '12V+' to 'Strobe C' also as shown on the diagramme?
The bell and strobe on my, rather old, Scantronic 9100 failed some time ago and I have finally got around to investigating. On removing the bell box cover, I discovered that some of the cable connections have corroded and become disconnected.
The external bell box does not contain any module...
