Code Blue Audio Paging Top CB5 BSL CC - 42480

Code Blue 42480 Audio Paging Top CB5 BSL CC

Overview

The Code Blue 42480 is a replacement audio paging top assembly designed for the CB5 series tower enclosures. This component sits atop the tower structure and serves as the integration point for audio input signals bound for the paging amplifier. It accepts analog audio signals and routes them through the internal paging amplifier block — essential when the top-mounted audio interface has failed or requires service. Model 42480 is the correct replacement part for CB5-series towers specifically.

Compatibility

This part is designed exclusively for Code Blue CB5 series towers. The CB5 line uses 12–24V DC power distribution to the paging amplifier, and the 42480 top assembly integrates with that voltage range. It will not fit CB1, CB2, CB4, CB6, CB9, or CBRT series enclosures — each series has its own distinct mounting footprint and internal wiring harness. Verify your tower series before ordering.

Installation Notes

Replacement requires partial tower disassembly and disconnection of the existing audio input harness from the amplifier block. The new top assembly must seat flush against the tower's upper flange; misalignment can cause intermittent audio dropout or signal degradation. Consult the Code Blue CB5 service manual for torque specifications on the mounting bolts and proper audio connector orientation — reversed polarity on audio lines can damage downstream amplification stages.
