All the wiring goes in parallel to the last detector, with a single resistor
at the last smoke.  Also, you may need a power supervision relay if the smoke
doesn't have it built in.

This is really basic stuff, it sounds like you don't have the experience to be
working on a fire alarm reliably.  Please have someone who knows what they are
doing inspect your work.
