directs that where the building is sprinklered, that a fault within one floor area shall not prevent voice communication in another. Is the fault referred to in the data loop serving active field device, and/or supporting field devices or does this refer to a fault in a voice communication circuit. In other words, does one have to split up voice communication speakers into different circuits when they serve different floor areas?

If the floor area your are referring to is on a different fire alarm zone, then good engineering practice (and the intent of this Section which relates to distributed type systems) would entail a separate speaker zone as well or a buss isolator (added March 13, 2013).
I would recommend that you obtain the latest version of the Installation Standard which includes the February 2011 Amendment. The Amendment is, unfortunately, not available as a separate document (which, in my opinion, it should be).
