16ohm sounder , is a speaker , across 12vs will short the panel and perhaps blow speaker , it goes to speaker terminals if the panel has them
Actually hook it up and enroll the devices on the bench and get used to the menus and see how it all works
Then simply delete all devices or better default the panel and do it all on site , that way you don't have to scratch your head so much on site as you will have got used to it a bit
Hence default panel once you played with it a bit
Example I do the really know him but Samsung has a couple of protocols and wrong settings can make the menu skip UART settings etc , if that's the right word so thought maybe as a remote device controller that's why it was doing that , as on the cam it will always work
