Code Blue CB9S00048 24V Gateway Backplate
Overview
The CB9S00048 is a 24V DC gateway backplate designed for Code Blue CB9 Series tower systems. This component supplies regulated 24V power to the CB9 tower assembly and integrates audio input routing, making it the central power and signal interface between external power supplies, paging amplifiers, and the speakerphone tower itself. Deploy this where you need to convert a standard 24V DC feed into the CB9 tower's native operating voltage.
Compatibility
The CB9S00048 is a direct replacement and service part for Code Blue CB9 Series towers only. It is not compatible with CB1, CB2, CB4, CB5, CB6, CBRT, or legacy series models — each tower family uses its own power and backplate specification. Verify your tower model before ordering; using an incompatible voltage or backplate type will prevent operation.
Installation Notes
The CB9S00048 supports wall, pole, recessed, and rack mounting configurations. Mount the backplate according to your tower's enclosure design, then terminate the 24V DC input (positive and negative leads) and audio input lines to the labeled terminals. Ensure your upstream 24V power supply can deliver sufficient current for the CB9 tower's total load — undersized power supplies will cause intermittent audio dropout or shutdown. Use shielded audio cabling where runs exceed 10 feet to avoid hum or interference pickup on the audio input line.
