The digital PROANNOUNCE manager DPM 4000 represents the central unit of the system. It is used to control and

necessary information about the DPM 4000 and its available modules.
The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies are extremely
variable. This allows configuring the system to basically match any requirement. The system is capable of managing up
to 16 paging stations and up to 100 output lines. More than 150 control inputs and outputs are available for controlling
and monitoring purposes providing the possibility to generate and manage logic levels and analog levels as well. For
