Aiphone GT-103HB 1x3 Module Surface Mount Box
Overview
The Aiphone GT-103HB is a vandal-resistant surface mount enclosure engineered for the GT Series modular entrance panel system. This single-row, three-module configuration delivers a rugged mounting solution for multi-unit residential, commercial, and institutional access control deployments where surface installation is required rather than recessed mounting. The GT-103HB (often searched as GT 103HB) is part of the broader Aiphone IP phone and intercom catalog, and it eliminates the need for a separate back box when deployed in surface-mount scenarios.
Key Features
- Vandal-Resistant Design: Withstands physical impact and tampering attempts common in high-traffic entrances, lobbies, and outdoor institutional settings — essential for unattended access points where equipment is exposed to public contact.
- Three-Module Capacity (1x3 Configuration): Accommodates three GF-3F modules in a single horizontal row, allowing you to deploy a combination of audio intercom, video call buttons, or relay signaling modules without stacking units or requiring multiple enclosures.
- Surface Mount Form Factor: Installs directly on walls, door frames, or pillars without recessing into walls — faster installation and ideal for retrofit projects, leased spaces, or environments where cutting into building structure isn't permitted.
- GT Series Ecosystem Integration: Works with the complete Aiphone GT Series lineup, including audio and video tenant stations, security guard stations, and external signaling relay modules, enabling flexible intercom and access control architectures across residential, commercial, and institutional facilities.
- No Back Box Required: The GT-103HB is a complete standalone enclosure for surface mounting — you do not need a separate GF-3B back box. This reduces part count and simplifies procurement for surface-mount installations.
- GF-3F Module Compatibility: Designed exclusively for GF-3F (1-row) modules. Confirm your module type before ordering to ensure correct integration with your entrance panel system.
Integration & Compatibility
The GT-103HB integrates with the complete GT Series modular architecture, supporting audio call stations, video call buttons, relay modules for door strike or gate control, and connection to security guard stations. It is compatible with GF-3F modules only; it is not compatible with larger or deeper module variants. The unit's surface mount design makes it especially suitable for intercom and access control system deployments where minimal structural modification is desired or permitted.
When to Choose a Different Model
If your deployment requires more than three modules in a single row, or if you need recessed installation into walls, consider larger variants within the Aiphone GT Series surface mount or back box lineup. If you require a larger module capacity or need to consolidate multiple entrance panels into a single larger enclosure, consult the full GT Series catalog to identify a model with higher module density or alternate mounting configurations.
Frequently Asked Questions
Q: Does the GT-103HB require a back box for installation?
A: No. The GT-103HB is a complete surface mount enclosure and does not require a separate GF-3B back box. It mounts directly to the wall or frame.
Q: What modules are compatible with the GT-103HB?
A: The GT-103HB is designed for GF-3F (1-row) modules only. Confirm your module type before installation.
Q: Can I install the GT-103HB outdoors?
A: The GT-103HB is vandal-resistant and built for high-traffic indoor environments (lobbies, residential buildings, institutional entrances). Verify with the manufacturer whether additional weatherproofing is needed for exposed outdoor mounting or if an outdoor-rated variant is available for your climate.
Q: How many modules fit in the GT-103HB?
A: The GT-103HB is a 1x3 configuration — three modules in a single horizontal row.
Q: Is the GT-103HB compatible with other Aiphone intercom systems?
A: The GT-103HB is designed for the Aiphone GT Series modular system. It integrates with GT Series audio stations, video call stations, relay modules, and security guard stations. Compatibility with other Aiphone product lines should be verified with Aiphone or your integrator.

The GT-103HB is a pragmatic choice for integrators deploying the Aiphone GT Series in retrofit or new-build projects where surface mounting is the path of least resistance. Its three-module capacity and vandal-resistant enclosure make it suitable for small-to-medium multi-tenant residential buildings, office lobbies, and institutional entry points. The fact that it eliminates the need for a separate back box simplifies your bill of materials and speeds installation — two real gains in fast-track projects.
Technical Highlights:
- 1x3 Module Configuration: Three GF-3F modules in a single row provide enough density for smaller buildings (up to 3 separate call stations or mixed audio/video/relay modules) without requiring multiple enclosures or stacked units.
- Vandal-Resistant Form Factor: Built to withstand physical tampering and impact in high-traffic public areas — a meaningful advantage over lightweight generic enclosures in institutional and multi-tenant deployments.
- Standalone Surface Mount (No Back Box): The GT-103HB is a complete enclosure; you do not need a GF-3B back box. This reduces part count and makes procurement simpler for surface installations compared to recessed deployments that require separate backing hardware.
Deployment Considerations:
- Confirm module type before installation — the GT-103HB accepts GF-3F (1-row) modules only. Mixing module types or attempting deeper modules will result in fit or functionality issues.
- Surface mount installation is faster than recessed mounting but leaves the enclosure more exposed to physical contact and environmental stress. Plan for adequate protection or weatherproofing if mounted in semi-exposed areas (covered porches, lobby edges).
- Three-module capacity is a practical ceiling for many small buildings, but if your design requires more than three call points on a single entrance, you will need multiple GT-103HB enclosures or a larger variant with higher module density.
The GT-103HB is best suited to small residential buildings (up to 3 units), small commercial lobbies, or institutional entry points where three call stations or a mix of audio, video, and relay modules will handle traffic. For larger multi-tenant or multi-building deployments, evaluate the full Aiphone GT Series catalog to find configurations with higher module counts or multiple enclosures deployed strategically across your property.
