Code Blue CB1S00851 GWT Remote Expansion Module

Overview

The CB1S00851 is a GWT remote expansion module used to extend Code Blue emergency communication systems beyond a single base tower or station. It adds input/output capacity at a remote point in the system, letting an installer wire additional call points, sensors, or paging functions into an existing Code Blue deployment without replacing the main controller. This is the right part when a campus or facility emergency phone layout needs a secondary connection point rather than a full new base unit.

Compatibility

Designed as a replacement and expansion part within the Code Blue GWT product family. Confirm the specific tower or wall-mount station model in your deployment before ordering, since GWT module revisions are matched to the paging amplifier and control electronics of the base unit.

Installation Notes

Runs on 24V DC power — verify your system's power distribution can supply this before wiring the module in, since some Code Blue paging amplifiers were produced for 12-24V DC ranges depending on production era. Confirm the DC supply matches this module's requirement rather than assuming a shared rating across every unit in a multi-tower system. As a control-level component, this module belongs inside the equipment enclosure and is not rated for direct outdoor exposure — mount it in the same protected compartment as the rest of the base electronics.

Model CB1S00851 ships as a factory-new replacement part for technicians maintaining or expanding an existing Code Blue installation. Stock the correct part number before a service call — mismatched expansion modules across a multi-station system are a common source of paging failures during emergency phone maintenance.
