583381.31

Approval: G 210122
Part of EN 54-16 approval 0786-CPD-20997

The system communication unit (SCU) is used as a digital audio storage for the VARIODYN® D1 sound system. It is possible to record and reproduce a plurality of audio streams at the same time.
The connection to other VARIODYN® D1 modules is implemented via Ethernet and permanently monitored. The audio memory for availability critical alarms and notifications for evacuations carried out according to IEC EN 60849 in a non-volatile flash memory. The storage capacity is according to format about two hours.
More pre-recorded messages such as announcements, signals or advertising copy are stored on a hard disk. The storage capacity is thereby according to the format of about 1000 hours.
The SCU can also be used to log and record announcements. These are also stored in memory and backed up with date, time and trigger information. The automatic intermediate storage enables to play announcements that cannot achieve all the goals while releasing this.
