Code Blue SLNF0421 12VDC Power Supply

Overview

The Code Blue SLNF0421 is a 12VDC power supply module engineered as a direct replacement component for Code Blue surveillance and communication tower systems. This unit delivers regulated 12-volt DC power to compatible Code Blue enclosures and devices. The SLNF0421 is sourced as a factory-new genuine replacement part for installations requiring stable power input to tower-mounted equipment, paging amplifiers, and related control systems.

Compatibility

The SLNF0421 is designed for use with Code Blue CB1w tower systems and other Code Blue enclosures specifying 12VDC input. Verify your specific system documentation before ordering — this part is a replacement component and compatibility depends on your existing installation's power architecture. Consult the Code Blue parts catalog or your system documentation to confirm the SLNF0421 is the correct part number for your application.

Installation Notes

This is a replacement power supply module. Installation requires disconnecting the existing unit and connecting the SLNF0421 to the same power terminals and wiring harness. Ensure all power is disconnected before installation. The unit operates on 12VDC input and must be installed in an environment protected from direct moisture exposure — verify mounting location meets the environmental requirements of your Code Blue enclosure. Do not exceed rated voltage or reverse polarity, as this will damage the component and connected equipment.
