Wiring diagrams
Wiring diagram with SCS BUS connected (the power amplier plays back
the sources from the 2-wire sound system).
Wiring diagram with SCS BUS disconnected (the power amplier is independent
from the SCS BUS and plays back the source connected to the AUX IN input).
Note: The desired input, SCS or AUX IN, must be selected using the local keys (see the installation manual for the correct procedures).
A: 1-9 address of the amplier room
PF: 1-9 address of the amplier sound source:
M1**: - (no congurator) volume level equal to 20% and “MUTE” :
mode: this mode, when the video door entry system is being used the
volume of the sound sources will be decreased
1 volume level equal to 20% but “MUTE” mode not available”
2 volume level equal to 50% and “MUTE” mode: in this mode, when the
video door entry system is being used the volume of the sound sources will
be decreased
3 volume level equal to 50% but “MUTE” mode not available
Description
To access the congurator sockets remove the protection cover. A description of the
congurators is printed on the inside of the cover.
4 volume level equal to 100% and “MUTE” mode: in this, mode, when the
video door entry system is being used the volume of the sound sources
will be decreased
5 volume level equal to 100% but “MUTE” mode not available
SLA amplier slave operation mode:
M2: - (no congurator) when the amplier is switched on, the last source which
was on is activated, “FOLLOW ME” mode
1-4 when the amplier is switched on, the source with the same conguration
as that set on the device itself switches on (example amplier with M2=2,
in this case the source with S=2 will switch on), “NO FOLLOW ME” mode.
M3 - (no congurator) working correctly
1 both the outputs reproduce the signal received on the LEFT channel
2 both the outputs reproduce the signal received on the RIGHT channel
3 the amplier reproduces a monophonic signal on both the loudspeaker
outputs
** This mode can only be activated when the Sound System is integrated with the 2-wire
audio and video door entry system. This combination allows the “pager” function and
the volume level is set via the congurators.
