Loudspeakers

The voice alarm controller has 6 zone outputs (Z1 to Z6). Each zone output consists of 2
redundant loudspeaker lines (line A and line B). Normally, calls and BGM are distributed to a
zone over both loudspeaker lines. If one of the loudspeaker lines of a zone fails, it is still
possible to distribute calls and BGM to the zone over the remaining loudspeaker line.
