IEC 60849 'Sound Systems for Emergency Purposes' applications

For incorporation within applications specified to the requirements stated in the International Standard IEC 60849 Sound Systems for Emergency Purposes, a Programmable Logic Controller (PLC) can be integrated into the d&b Remote network. It can report faults and set the d&b system into a defined alarm status. Input channel, equalization, volume, delay and filters are adjusted. For this purpose the respective AmpPresets of the d&b amplifier are used. When the alarm ceases the original settings for the d&b system can be recalled. A PLC can run as the primary master and the R1 remote control can be configured as the secondary master. In this configuration the PLC commands will override the R1 remote control software.
