Scantronic ION expander help!

We’ve recently installed a scantronic ION40H alarm system, and I’m having problems addressing the 10 zone wired expander exp-w10. It sounds like it’s been successful in getting an address, but then proceeds to beep for about 30secs. There are other keypads on the same bus connection, daisy chained through the expander, so I don’t think it’s a problem with the cable. The display on it says 1-03, on a repeating cycle. Any help appreciated
