Description
The Valcom V-ACS-X48-45 is an expansion module for the V-ACS45 Advanced Communication System that adds 24 talkback stations to bring the total system capacity to 48 stations on a 45-ohm speaker load. All speaker and I/O terminations are made inside the ACS enclosure, keeping the installation compact. The module adds dual FXS access ports, dual auxiliary audio inputs, 3 programmable switch inputs, 4 programmable relays, 24 flexible non-blocking audio paging groups, 8 bell schedules, NTP time updates, and integrated 59th-minute and data-based clock correction. Windows-based programming and administrative software provides configuration without field-level programming expertise.
The Telecom Spot Expert Review
The V-ACS-X48-45 is the first expansion step for a facility that starts with the 24-station V-ACS45 and grows beyond it. Adding this module doubles the talkback station capacity without replacing the base unit or re-wiring the speaker infrastructure — a significant cost advantage over competing systems that require full controller replacement at each tier. The NTP time sync and clock correction features mean the expanded system also keeps the facility's analog clocks accurate, so the ACS handles both communications and time distribution from the same infrastructure. For facilities that want SIP integration, that capability is available alongside the traditional FXS telephone port access.
