Aiphone GT-203HB 2x3 Module Surface Mount Box
Overview
The Aiphone GT-203HB is a vandal-resistant surface mount enclosure engineered for multi-module GT Series entrance panel installations. The 2x3 configuration (2 horizontal × 3 vertical module slots) lets you stack audio modules (GT-DB), video modules (GT-VB), and their NFC-enabled variants in a single wall-mounted frame, eliminating the need for separate scattered boxes in residential lobbies, commercial entrances, and multi-tenant access control environments. If your GT Series deployment spans more than one audio or video module, this box consolidates them into a single, protected mounting point.
Compatibility
The GT-203HB integrates directly with the Aiphone GT Series modular architecture, supporting:
- Audio modules: GT-DB (standard and NFC variants)
- Video modules: GT-VB (standard and NFC variants)
- Tenant stations: GT-1A (audio), GT-1D (audio), GT-1C7 (video), GT-1M3 (video)
- Guard stations: GT-MKB-N security/concierge module
Works within expanded GT Series systems supporting up to 25 tenants per trunk and 125 total tenants per video or audio bus controller. Requires standard two-conductor wiring for audio and video signal distribution.
Installation Notes
Mount directly to vertical surfaces (walls, door frames) in entrance applications. The enclosure is designed to withstand vandalism-level impact, making it suitable for high-traffic or outdoor-exposed lobbies. Confirm wall substrate capacity for the combined weight of the box plus installed modules before fastening.
