Description
The Valcom V-ACS-X72-45 is an expansion module for the V-ACS45 Advanced Communication System that adds 24 talkback stations to bring the total system capacity to 72 stations on a 45-ohm speaker load. All speaker and I/O terminations are made inside the ACS enclosure. The module provides dual FXS access ports, dual auxiliary audio inputs, 3 programmable switch inputs, 4 programmable relays, 24 flexible non-blocking audio paging groups, 2 music groups, 8 bell schedules, NTP time updates, and integrated 59th-minute and data-based clock correction. Windows-based programming and administrative software handles configuration without specialized field tools.
The Telecom Spot Expert Review
The V-ACS-X72-45 is the second expansion step for a V-ACS45 system that has already added a V-ACS-X48-45, or the direct path to the maximum 72-station capacity for facilities that know they need it from day one. At 72 stations, the ACS platform covers large school campuses, multi-wing healthcare facilities, and mid-size manufacturing operations where talkback intercom at every work area is required. The two dedicated music groups are an addition over the 48-station module, allowing different background music sources to play in separate areas of the facility simultaneously while the 24 audio paging groups remain available for zone-selective announcements independently of the music zones.
