Separate power for Ext siren

Hi all. Just about wired up the sensors but still pondering whats best to do with the external bellbox and internal siren.
I was going to run them both from the panel but Im aware that theres a limit before frying the board, 24v i think it is and both would be right at that limit together.
So was wondering if I could offload the power for either/both using a couple of these adapters and only connecting the data to the panel pro?
Then use a power splitter?
Would this work?
Thank you
