Ok thanks for that will give it a go.

Yes zones are correctly wired with 4k7 with 2K2 end EOL. I have addressed Address 1:keypad address 2 :expander address 3 keypad so can you have a keypad adressed as 1 and and expander adressed as 1 thanks

Hi 1 expander and 2 keypads control panel seeing both keypads and in walk test it sees the tamper on the expander but not the zones.

Hi got a problem with a Scantronic 9751 it won’t see the zones on a hard wired 8 Zone expander board it will see the expander tamper switch but none of the zones. indicated fully supervised loop with link is there somewhere in the programming that you have to do but the last one I did I just put FSL link in and it could see zones 9 onwards. I can program the zones from 9 onwards but it won’t see them when I walk test. any help would he great.
