Installation/configuration notes
Mounting
The sound projector mounts to the ceiling or to the
wall in such a way, that the connection cable is not
visual which is important in areas where vandalism is a
potential hazard.
Power setting
A one-meter long fire-resistant six‑core connection
cable is standard fitted to the loudspeaker. Each core
is a different color, and is connected to one of the
primary taps on the transformer.
