12v incoming to a smart Rio can cause all sorts of issues. To be honest though I've seen it done many a time and no problems whatsoever. In fact, I'm guilty, when we first started using them I did it on my first smart Rio.

Did you leave it in?

Did you leave it in?

Knew no different at the time. Back in those days we were given a box and told to fit it. It was taken out on an RI after we had proper galaxy training.

I am talking years and years ago here.

The software on main panel is 1.5

 

The main panel is connected to the P RIO just by 2 wire no power linked, all sensors take power from that P rio, ie between the two building is just two wire link. The only thing is the RF box its wired as end res - house key pad - ether net - main panel - rf box -(2 wire no 12v)- p rio - keypad - end res so the last keypad is powered by the rio. The rf is last powered on the main panel, but is assigned to a zone on power rio so don't know if this would be an issue.

You'll need a 0v common link between the main panel and the Powered Rio.

Only if switching things from the panel and supplying from the power rio.

Technically rs485 does not require a common neg

I had the same on a dimension,duff panel mate,sent back to honeywell as they were interested too

Orite, don't think I've ever fitted one which hasn't had something switched from it. Hence allways having a common neg.

Must be a bug then,

I'll try it on my g2 tomorrow, see what happens

The main panel has 2 bell boxes set to use internal battery on alarm, the power rio also has a single bell box connected.

Disconnect Rio , do you get same fault , might be pcb fault

all the links present on the rio? never used them but thy can be put in different modes with the ee links for example. And yeah deffo need a ov common  up. A premier for instance, wont see anything on the bus with no common ov.
