System sensor B200S-LF sounder bases, how do they act connected to NAC power?

Hi, new here, first question.

Does anybody here know how the B200S acts when it’s connected to NAC power instead of aux power? So right now they are receiving supervisory power in reverse from red+ black-. In an alarm event power will be applied to them in the forward way. My design matrix says they’re supposed to sound individually if that detector goes into alarm. And if I had them connected to aux power I’m sure they would. Anybody know if they can use the reversed supervisory power to sound individually?

Hopefully I’m making sense.

Thanks,
Bryan

You have to program the head that is attached to base to its own output group per device to sound on its own under alarm.
Those bases are supposed to have 24vdc non resettable constant, not on a nac.
