The PRA-SCL is the most powerful version in a range of system controllers.
The system controller manages all system related functions in a PRAESENSA
Public Address and Voice Alarm system. It routes all audio connections
between network-connected PRAESENSA audio sources and destinations. It
supervises and plays back messages and tones, stored on its flash memory,
either scheduled or manually started from a call station or PC. It manages
the routing of background music streams, along with business calls and
emergency calls, all based on priority level and zone occupancy. It
collects all status information of connected system devices, manages the
event logs and reports faults.
The system controller is network‑connected via OMNEO and DC‑powered from a
multifunction power supply with integrated battery backup, accommodating
both centralized and decentralized system topologies. Connections to other
devices in the system are made using the built‑in 5‑port switch, supporting
RSTP. The built‑in web server allows for system configuration using a
browser.
