I'm talking about 12VDC smokes w/ aux contacts (panel powered). Many alarm
panels do not support 2-wire smoke loops.

Like this one:

That'll work, but then you need to add notification appliances as well,
and that's a whole nother ball of wax (unless you use standard 24VDC
detectors with sounder bases)

basically I still think the 120VAC/battery detectors with tandem
connection are probably a simpler, more economical choice for a home
install and provides all the functionality you need - the full "system"
is useful for larger installations where you need annunciation by floor,
zone, etc.

Hey, let's go addressable, let's just get silly
