Code Blue SLNF0252 CB1W Power Supply 4G LTE Backup

Overview

The SLNF0252 is a dedicated power supply and cellular backup module for Code Blue CB1W speakerphone towers. It provides dual 12–24V DC output with integrated 4G LTE failover connectivity, designed to keep emergency communication systems online during mains power loss. Mount the supply on a wall, pole, recessed location, or rack as your site requires. This accessory ensures uninterrupted operation of CB1W units in facilities where network continuity is non-negotiable—hospitals, universities, industrial plants, and municipal emergency response sites.

Compatibility

The SLNF0252 pairs directly with Code Blue CB1W tower speakerphones and is part of the CB1 Series accessory ecosystem. It is designed as a replacement or upgrade component for existing CB1W deployments. Confirm your current CB1W model revision before ordering to ensure voltage and connector compatibility.

Installation Notes

Mount the SLNF0252 using the supplied wall, pole, recessed, or rack hardware appropriate to your location. The unit accepts standard 12–24V DC input and outputs dual circuits for redundancy. Ensure adequate ventilation around the enclosure to prevent thermal buildup during continuous operation. Route power and cellular antenna connections away from high-current circuits and RF noise sources to maintain clean signal integrity on the 4G LTE backup path. Consult the CB1W tower installation documentation for specific connector pinouts and wiring diagrams.
