I have to install AC interconnected smoke detectors in an investment
home I own (county code) and am running into a bit of a problem.

Most interconnected require the units all be on the same wire, which
is simple enough for new construction, but trying to run one wire from
the attic to the basement in a house built in 1954 is a world of fun
beyond what I want to do or pay someone to do.

I found Kidde makes AC smoke detectors that are interconnected by
wireless. Does anyone have experience installing these? Do all units
have to be on the same circuit in order for the wireless
interconnectivity to work?

Kyle, I found a review about Kidde smoke detectors at Amazon.com
by a fellow who installed some of them.

Pro: Easy to install as a replacement for a wired only Kidde smoke
detector.
Great to connect wire lnked systems on two separate floors of your
home using two of these wired units.

Cons: uses a different base plate than other Kidde products so you
must remove any other Kidde base plate - which does not make sense.
Tends to trigger other wireless units during installation process so
be sure to wear ear protection while installing.
This wireless to wired unit must be on the same electrical circuit as
other wired units to which it is connected so you cannot add just a
link wire to extend the wired system to this unit. You must connect
the power and the link wires to this unit from other Kidde wired
units. That limits flexibility for placement.
