Adding DSC Expander (PC5108)

I'm updating my ancient DSC to a newer DSC model(PC 1864) and need to add an expander. Just a bit confused to where the wires from the expander labled "TAM" go. It says to wire to "COM" on main circuit panel but which "COM"... any one of them?

Also have a motion sensor wired to the expander which needs to be powered. Do the power wires from the Motion need to go directly to the main circuit panel or can I wire them directly to the Expander someplace?

Thanks in advance.

The COM from the expander can connect to the AUX- terminal.
Power for remote powered items, like your motion sensor, can connect to the AUX+ and the AUX- terminals.

To close off the tamper terminal, you can jumper it to any COM terminal (they are all electrically common). In a residential system, a case tamper is rarely necessary.
