The HUAYAN HAG-1 is a robust and reliable Marine Automatic Telephone system designed for seamless communication on board vessels. As a vital piece of maritime equipment, it facilitates clear and instant voice communication between key locations on the ship, such as the bridge, engine room, forecastle, and aft station, as well as with other equipped vessels.
The “Auto Telephone” designation means it operates on an automatic exchange system, allowing users to dial extension numbers directly without manual switchboard operation, much like a traditional office PBX system but built to withstand the harsh marine environment.
