Conventional panels not as much a problem but addressable you want to
keep them separate to avoid bleed over
where horns can some times be heard with a buzz in them when system is
in normal mode.from the noise the addressable loop can inject.
had a sub job one time I warned them to use twisted wire on the
addressable loop they didn't and it came  over the restaurants fancy
sound system needless to say they had to strip all the wiring out and
replace with the right stuff. $$$
Some people never learn see it in high end houses all the time when
they try to use advanced panels with out the twisted wire.
