Running circuits together

[JoeRaisin]

Is there a code issue with running initiating circuits and notification
circuits in the same raceway?

Another tech made this assertion, but I think he is confusing it with
the out and return of a class A circuit.

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.

Thanks for the info guys. We are installing an MS-9600 and about 150
horn strobes. There wasn't much area where the runs could be combined
but I'll be sure to keep them apart.
