Description
Expand a Valcom MultiPath Intercom System by up to 24 additional talkback zones with the V-TCM, a 24-point expansion module with 45-ohm speaker I/Os, call switch inputs, and handsfree two-way switching that supports both one-way announcements and two-way intercom communication.
The Telecom Spot Expert Review
The V-TCM is the expansion card for MultiPath Intercom systems that have grown beyond the capacity of the base controller — each module adds 24 zones with full talkback capability, 24 call switch inputs for station-initiated calls, and the handsfree switching intelligence that lets stations operate in both one-way and two-way modes without manual configuration at the zone level. The 45-ohm speaker interface matches the standard MultiPath speaker load, so existing speakers in the facility connect directly without impedance matching transformers. Because it expands within the MultiPath architecture, the V-TCM integrates with the existing head-end controller and management software rather than requiring a parallel standalone system. For facilities planning for growth, this is the correct expansion path instead of replacing the entire paging infrastructure when zone count exceeds the original controller's capacity.
