WTB Wired Home Intercom, PST.

Our house is undergoing an extensive remodel and I would like to install a wired, press-to-talk intercom between the first and second floors (and the basement as well, if possible). Ideally, I would prefer a solution that draws no power when the PTT button is not pressed. Does something like this exist? At first glance it seems simple to make an intercom that only uses power to drive a speaker on the other end when the PTT switch is on.
