So I'm thinking of adding an NX-320E to my NX-8E system. Currently the cabinet is a bit full and since I was going to add multiple rate of rise sensors heat sensors in the attic, I was thinking of putting a cabinet in the attic for the NX-320E along with another NX-216E zone expander to handle them. It will make the wire runs shorter for the rate of rise sensors and I won't have to get them down the wall either.
Currently I have the NX-8E, one NX-216E, one NX-595E, one NX-584E, one LED keypad and one LCD keypad. I don't know how close I am to the power capacity. I might add a third a keypad, another LCD. Currently there is just a single battery in the cabinet. So I could move the current LCD keypad to the NX-320E since those keypads take more power.
Here is my question, I looked at the instructions and I see the input from the NX-8E, data goes to data and common goes to common and then the positive on the NX-320E goes to the Aux+ on the NX-8E. Since the NX-320E is also a bus extender, I don't see where you connect the POS to since the output terminal wise has a common and a data but no POS. Do you use one of the Out (either A, B or C) to power say the NX-216E or keypads? I see in the instructions for location 0 on segment 1, that you can set it to always on. The instructions don't say if this is how you handle using it as a bus extender but they do list the NX-216E as compatible. So that is the only thing I can see how to wire it up.
Here are the NX-320E instructions:
