EV SCDIA
GENERALITIES
Zone diagnostic module, complying with EN 60849, features a specific electronic diagnostic
system to ensure an autonomous control of the amplifying chain and eventual commutation to
back up amplifier . This control is done for each amplifier and for each loudspeakers line; eventual
anomalies are transmitted to the main central unit to provide for default indication .
The module is as follows equipped:
−
Switch system for zone configuration .
−
Output/input connections for low frequency and 100V signal towards the zone amplifier.
−
Output/input connections for 100 V loudspeakers line and feedback loop.
−
NA and NC remote contact output connections.
−
Automatic remote volume connection module.
−
Switch to allow back up operating mode.
OUTPUT/INPUT SIGNAL CONNECTIONS
- AMP IN
Terminal EUROBLOCK to extract -3 ways to use for audio balanced Low frequency signal– to
connect between the zone module and the amplifier zone.
- AMP OUT
Terminal EUROBLOCK extract -3 ways to use for 100V feedback audio signal- to connect
between the zone amplifier and zone module.
- SPKR / LOOP
Terminal EUROBLOACK to extract -4 ways to use for 100V audio loudspeakers line. Loop cable
from the last loudspeaker line to connect to the appropriate terminal.
OPTIONS
- RELAY
Terminal EUROBLOCK to extract – 3 ways – to use for NA and NC contact connections towards
external apparatus to be controlled for particular call, general call o for emergency call and to
diffuse pre-recorded messages.
- REMOTE CONTROL
Plug 6/6 is used to vehicle data Bus between the zone module and its remote module to survey
the background noise and adjust automatically the volume.
- BCK
2 positions switch is used to allow each zone module to effect the commutation to back up
amplifier in case of default amplifier.
