She will run another internal sounder too if you want, no probe.
As said by all of us you have a very strong panel and it will take a lot to kill it and the combo of Sab/scb is the best way to go.
The quieter sounder on sab is hardly noticeable to the untrained ear but still packs a punch none the less so don't worry about the draw unless you expand the zones or fit a further two rkp's.
Just remember to test the system periodically and enjoy :)
