Description
The Aiphone GH‑BC is the dedicated 2‑wire bus controller for legacy GH‑Series audio systems, acting as the central interface that distributes power, communication signals, and call routing between GH entrance panels and in‑suite stations. Designed to simplify system wiring, it manages the R1/R2 2‑wire bus, stabilizing audio communication and ensuring that calls from specific doors reach the correct tenant units. The GH‑BC supports long wiring runs suitable for multi‑floor buildings, provides reliable door‑release control signaling, and maintains system addressing for all connected stations. Though now discontinued, it remains an essential component in existing GH audio‑only installations, providing the core control and communication backbone for the entire system.
