Aiphone GT-4F 4-Module Front Frame
The GT-4F is a 4-module front frame engineered as the structural foundation for the Aiphone GT Series modular entrance station platform. Rather than a fixed-function device, this frame is a field-configurable housing that accepts up to four entrance modules in any combination—audio, video, or mixed. That flexibility matters: you can start with a simple audio setup and add video modules later without replacing the entire frame, reducing capital churn when access requirements evolve.
Key Features
- Modular slot configuration: Four independent module positions allow you to deploy audio-only entry points, video-only stations, or mixed audio-video setups in a single unified frame. Useful in multi-tenant buildings where some entrances need intercoms while others require video verification.
- Vandal-resistant construction: The frame is engineered to withstand impact and tampering at high-traffic public entry points and secured access environments. This matters if you're installing in lobbies, parking facilities, or outdoor courtyards where accidental or deliberate damage is a deployment risk.
- Aiphone GT Series backbone integration: The GT-4F connects directly to the GT Series modular intercom and access control ecosystem. It supports both audio and video signaling through the shared backbone architecture, meaning you avoid proprietary wiring or protocol adapters.
- NFC reader compatibility: When paired with optional Aiphone GT-DB-VN (audio/intercom module with NFC) and GT-MKB-N (NFC reader keypad module), the frame supports contactless credential reading at the entrance. This is relevant if you need credential-free entry for mobile key deployments or hygiene-focused access control.
- Compatible tenant station ecosystem: The GT-4F works with Aiphone tenant stations (GT-1A, GT-1C7, GT-1C7W, GT-1D, GT-1M3), meaning residents or staff can answer calls and manage access from interior monitors or IP endpoints. Simplifies two-way communication without additional gateways.
- Standard installation practices: Mounting and wiring follow conventional entrance station protocols documented in the Aiphone GT Series Quick Start and Full Installation Manuals. No exotic certification or integration work required if your integrator is familiar with modular intercom deployments.
Integration & Compatibility
The GT-4F is part of the Aiphone intercom and access control portfolio. It integrates seamlessly with all GT Series audio modules (GT-DB audio/intercom), video modules (GT-VB camera/video), and optional NFC reader kits. If you are standardizing on modular entrance station platforms, the GT-4F provides a common frame for mixed deployments across a facility—reducing spare parts inventory and simplifying training for installation and maintenance crews.
Audio and video signaling flows through the GT Series backbone, which supports both analog and IP connectivity depending on your tenant station and NVR choices. Ensure your integration plan accounts for power delivery (typically 24VDC from a central supply) and any IP bridging if you are mixing analog intercoms with IP-based video recording.
When to Choose a Different Model
If you need a single-module frame (one audio station or one camera only), a smaller or single-gang variant may be more cost-effective and compact. If your deployment requires outdoor weatherproofing beyond vandal resistance—such as direct rain, submersion, or salt-spray environments—verify the environmental rating of the modules you plan to install; the frame itself is suited to covered outdoor entries but not full environmental enclosures. Consult the module-specific datasheets for IP ratings.
Frequently Asked Questions
Q: Can I upgrade the GT-4F from audio-only to audio-video later?
A: Yes. The frame has four independent module slots. You can install audio modules initially and add video modules when needed, provided you have space and power available from your 24VDC supply. No frame replacement is necessary.
Q: Is the GT-4F (often searched as GT 4F) suitable for outdoor use?
A: The frame itself features vandal-resistant construction and is rated for high-traffic entry points. However, full environmental protection (rain, snow, salt spray) depends on the specific modules installed. Verify the IP rating of individual modules (audio, video) before outdoor mounting. Covered outdoor entries are typically appropriate; fully exposed weathering may require additional shielding.
Q: What power does the GT-4F require?
A: The frame itself is passive and requires no dedicated power. Power demand depends on the modules you install. Typical audio modules draw minimal current; video modules (if equipped with lighting or IR illuminators) may draw more. Plan for a centralized 24VDC supply and check the module datasheets for total budget.
Q: Does the GT-4F support IP-based video recording?
A: Yes, when paired with GT-VB video modules. These modules can output video over IP to an NVR or VMS, or via analog CCTV. Consult the GT-VB datasheet to confirm codec support and network configuration options.
Q: Can the GT-4F integrate with my existing non-Aiphone intercom system?
A: The GT-4F is designed for the Aiphone GT Series ecosystem. Cross-system integration may require protocol bridges or custom wiring, which is outside the standard modular platform. Verify compatibility with your system integrator before specifying.
Q: What certifications or compliance standards apply to the GT-4F?
A: The frame itself is a passive housing. Certifications (FCC, CE, UL, etc.) typically apply to the active modules (audio, video, NFC readers) installed within it. Confirm the certification status of the specific modules you plan to deploy.

The GT-4F is a straightforward modular housing, but that simplicity is exactly why it works well in distributed access control and intercom rollouts. The four independent module slots on the GT-4F mean you can stage deployments without committing to a fixed audio-video footprint upfront. Build with audio, add video later—or start video-only and leave slots open for future expansion.
Technical Highlights:
- Vandal-resistant frame design: Engineered for high-traffic public entries where accidental bumps and deliberate tampering are real risks. This isn't optional cosmetics—it's structural robustness that keeps the unit operational longer in hostile environments.
- Four module slots, any mix: Audio modules, video modules, or blanks. No wasted space, no forced configurations. If you have twelve entry points and only six need video, deploy video modules to those six and audio-only to the rest without buying separate frames.
- Backbone integration with GT Series ecosystem: Audio and video signaling flow through a unified wiring and power backbone. Reduces cable runs and simplifies maintenance if your entire facility standardizes on Aiphone GT components.
Deployment Considerations:
- Power budget planning: The frame is passive, but modules draw power. Audio modules are negligible; video modules with IR or lighting can consume significant current. Size your 24VDC supply centrally and check module datasheets before finalizing the cabinet or power distribution location.
- Environmental limits: Vandal-resistant does not equal weatherproof. Covered outdoor entries are fine. Exposed sun, rain, or salt spray require module-level IP ratings and possibly additional outdoor enclosures. Don't assume the frame alone shields against weather.
Deploy the GT-4F in multi-tenant residential buildings, corporate lobbies, parking facilities, or campus entry points where you need scalable, mixed audio-video access control without proprietary wiring or protocol translation. Its modular approach makes it ideal for phased rollouts where budget or requirements evolve over time.
