David Clark U9925-GEM Wireless Gateway Expansion Module - 40995G-03

The David Clark U9925-GEM (40995G-03) Gateway Expansion Module is a system expansion component that allows multiple David Clark wireless gateways to operate together as a single coordinated wireless intercom system. It is designed for operations that want wireless only communications at scale, without requiring a wired master station as the center of the system. In aviation, this approach can be useful for large ramp areas, hangars, and ground support operations that need broader coverage and more simultaneous users for pushback, fueling, deicing, and maintenance coordination. It also fits marine, industrial, and emergency response environments where teams need reliable multi user wireless intercom capability across larger footprints.

• Interfaces up to four compatible wireless gateways to function as one expanded wireless intercom system.
• Supports scalable wireless only operation for up to sixteen users when paired with the appropriate number of gateways and belt stations.
• Optimized to handle the power requirements of multiple gateways to support consistent performance across the system.
• Designed for field installation in rugged operating environments.

Key Features

• Creates a higher capacity wireless intercom by linking multiple gateways into a unified system architecture.
• Supports aviation workflows that demand broad coverage and multiple simultaneous users, including ramp operations and ground handling coordination.
• Powered through a dedicated power cable arrangement intended to support reliable operation in demanding installations.
• Supports practical installation planning for facilities and mobile platforms where wired infrastructure is limited or undesirable.
