FUNCTIONS
This section describes the following main ZS-4328IO functions:
- Main and Backup Power Supply
- Network audio source management
- External audio inputs and internal player
- Fire alarm interface
- Telephone interface
- Software Configuration Function
MAIN AND BACKUP POWER SUPPLY
The main and standby power supplies are provided with the ZS-4328IO. The methods by which the power
supply detects faults can be configured through the software. In case of a main power supply fault, the main
power supply indicator light on the front panel of the ZS-4328IO turns yellow, and the output fault
automatically causes the backup power supply to provide power instead. After the main power supply is
returned to normal, it automatically again supplies power and the backup power supplies resume their
standby presence.
POWER SUPPLY PROTECTION
The ZS-4328IO power supply is protected. In case of a short circuit or other fault within theZS- 4328IO, the
main power supply is disconnected automatically.
NETWORK AUDIO SOURCE MANAGEMENT
Network audio source management.
Max 5 channels audio source playing in the network that can be external audio source or internal players.
AUDIO1~4 can be set for external audio source or internal players, AUDIO 5 only be set for internal player
