Expansion Unit for Talkback Intercom Systems

The Valcom V-2925A adds 24 ports of one-way paging or two-way intercom capability to a compatible controller. It is designed for facilities that need to scale an existing V-2924A system beyond its base capacity. Each unit delivers four distinct groups for paging and tone broadcast across the added stations.

Port Limits and Controller Dependency

A single V-2924A controller supports up to three V-2925A expansion units, creating maximum system sizes of 48, 72 or 96 ports. The expansion unit cannot operate independently and requires the controller for all call processing and power distribution. Total port count is fixed by the number of connected expansion units.

Scaling From Base Controller Capacity

This unit replaces the need for a second separate controller when the installation grows past the initial port limit. The jump is worth it when a facility needs 48 to 96 stations managed from one central point. It is not suited for standalone deployments or systems using a different controller platform.

Questions about this item

How many V-2925A expansion units can I add to a V-2924A controller?

You can connect up to three V-2925A units to a single V-2924A controller, giving you a total of 96 ports across the full system.

What does the 24-port count mean for daily use?

Each unit adds 24 stations for one-way paging or two-way talkback intercom, letting you reach individual rooms or zones from the central controller.

How does the four-group paging structure work on this expansion unit?

The 24 ports are organised into four groups, so you can broadcast tones or pages to a specific subset of stations without alerting the entire system.
