Are you sure you are using the right panel for this application? The place
was never wired properly by all appearances.Meeting code is going to be a
real issue. What kind of wire was used , is it a four wire because if it
is you only need two (unless you have 4-wire smoke detectors)in that case
if you have extra wire you can wire each device with a feed pair and a
return pair. If it is all in 2-wire your only real solution would be to
use zone expanders to cover each device( 4219's and they use 1K resistors
) or upgrade the panel to one with a polling loop and use modules
(4193sn)which would be a better fit but also more costly.
