4 wire smokes and EOL's

[CH®IS <sh@xxxxx>]

Ideally, you'd have only one smoke on a zone.  Unfortunately, I didn't
install todays disaster where there are 9 smokes on 2 zones.  Are zone
expanders really that expensive?

Anyway... I'm now wondering about how to do resistors correctly when you
have more than one smoke (either daisy chained or home run) on a zone.  Do
you have a resistor in each smoke, or just one at the end.  Being a normally
open contact (DSC 5010), it would make sense to have them in each smoke, but
I've seen them installed both ways.
