5.3.5 Remote controls
The voice alarm controller has 2 sockets for remote
controls. Use shielded Cat-5 Ethernet cables with RJ45
plugs to connect a remote control to the voice alarm
controller. See figure 5.5 for connection details.
5.3.6 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 (see
figure 5.8).
