The PRA-SCL is the most advanced system controller in the PRAESENSA Public Address and Voice Alarm series, managing all system functions, including audio routing, message playback, and background music, prioritized by call type and zone occupancy. It monitors device statuses, logs events, and reports faults. Network-connected via OMNEO and powered by a DC multifunction supply, it supports both centralized and decentralized setups with a built-in 5-port switch. The controller manages up to 250 devices across 500+ zones, with secure AES128 and TLS encryption, a web server for configuration, and dual redundancy for mission-critical reliability.
The OCA Alliance is a not-for-profit corporation formed to promote and support the AES70 standard for Open Control Architecture (OCA) as a media networking system control standard for professional applications.
