I have a system dating back to early 2000's with an Accenta G3 panel and a Lynteck Vortex bell box. The LEDs are failing on the box and I've got a Pyronix Deltabell to fit ( with backlighting) I believe there are 5 wires feeding the box Hold +, Hold- , TG- , STB- and Return. The Deltabell has connections T , STB, Bell, 12v + and -. Could anyone tell me how to swap the wires over? Do I need to fit a link between T and 12v- ? Also do I need a resistor between Bell and 12v+ on the panel? I think I may be out of my depth here and would appreciate any help
Many thanks
