Finalizing Elk security setup, and have a few lingering questions.

[WayneW]

I home-ran all my 4 wire smokes contacts, but daisy chained the power between all of them with a supervision relay at the last detector. That only requires one input for power status to all the smokes.

The key to this working right is to make sure the physical connection to each smoke is also done right. If you just loop the wire around the screw and go to the next one, you aren't monitoring that detector, just the loop. You should have separate connections such that if a screw backs out (I saw it when I bought this house) the power lead is interrupted.
