Description

Code Blue SLNF0281 CB1S Sbl Wem Np 277V 4G LTE Expansion Module

Overview

The Code Blue SLNF0281 is an expansion module designed to extend the audio capabilities of compatible Code Blue paging amplifiers. It's built for deployment in demanding environments where durability and reliable communication are critical. This module specifically addresses scenarios requiring enhanced audio output or integration into systems that benefit from its rugged construction and specific power requirements.

Compatibility

This SLNF0281 expansion module is designed for integration with Code Blue paging amplifiers that support a 12-24V DC power input. It is intended as a replacement part for units that began utilizing this DC power range during production. Verify your existing paging amplifier's compatibility with 12-24V DC input and the SLNF0281 module before installation.

Installation Notes

The module requires a 12-24V DC power source, supporting PoE (802.3af) for simplified wiring where network infrastructure is available. Its IP68 rating ensures protection against dust ingress and immersion in water up to 1.5 meters for 30 minutes, making it suitable for outdoor or wash-down environments. Ensure all connections are properly sealed to maintain the IP68 rating.
