Aiphone GT-303HB 9-Module Surface Mount Box
Overview
The GT-303HB is a vandal-resistant surface mount enclosure designed for the Aiphone GT Series modular entrance panel system. This 3×3 module configuration accommodates up to 9 entrance modules in a single mounted unit, supporting mixed audio and video installations across multifamily residential, commercial, and access control deployments. The surface mount form factor allows direct attachment to exterior building facades and entry points without requiring a recessed rough-in, making retrofit installations faster than in-wall alternatives.
Compatibility
The GT-303HB integrates with all Aiphone GT Series entrance modules, including GT-VB camera modules, GT-DB audio modules, and their NFC-equipped variants. It pairs with GT Series control units and tenant stations (GT-1A, GT-1C7, GT-1C7W, GT-1D, GT-1M3), security guard stations (GT-MKB-N), and supports distributed architectures via GTW-LC gateway connectivity. Module placement within the 3×3 grid is user-configurable, allowing you to optimize layout for your specific entry configuration—camera modules at eye level, audio below, or mixed arrangements depending on your intercom topology.
Installation Notes
Designed for surface mounting on exterior building facades and entry points. Refer to Aiphone's GT Series Quick Start Installation Guide and Full Installation Manual for specific wiring requirements, module placement strategies, and system configuration details. The vandal-resistant construction is appropriate for high-traffic public entry points; confirm environmental exposure (rain, salt spray, freeze-thaw cycles) against your site's operating climate before final placement.
