Introduction
The Bosch PRA-SCL System Controller is the most powerful unit in its range, designed to manage all system-related functions within a PRAESENSA Public Address and Voice Alarm system. It efficiently routes audio connections between network-connected PRAESENSA audio sources and destinations.
This controller supervises and plays back messages and tones stored in its flash memory, supporting both scheduled and manually initiated playback from call stations or PCs.
