DPPC (in practice often “ARC/MARC”) is a specialized workplace for receiving alarms, faults and status information from connected sites. In the case of physical security, it is especially important that its outputs are followed by a clear procedure for the workers on site.
Why are so many standards devoted to this
Key are the requirements for odolnost (power, connectivity and control-room security), because an alarm receiving centre outage can interrupt monitoring of connected sites.
For larger operations, certification and processes according to EN 50518 are also dealt with.
