Aiphone GTV-DES202B Modular

Aiphone GTV-DES202B 10-Key Video Entrance Panel Kit

Overview

The Aiphone GTV-DES202B is a 2x2 modular video entrance station with integrated digital directory, audio/video communication, and direct-dial access control. Designed for multi-tenant and secured-entry applications, the GTV-DES202B combines video capability, hands-free voice communication, a customizable VFD display screen, and a 10-key numeric keypad in a single modular platform. This entrance system supports up to 500 tenant stations, 16 entry panels per system, and 4 concierge stations, making it suitable for mid-to-large residential and commercial deployments.

Key Features

• Modular Architecture: Constructed from swappable modules—video (GT-VB), audio (GT-DB), display (GT-NSB), and keypad (GT-10K)—allowing flexible configuration and future expansion without replacing core infrastructure.
• 10-Key Direct-Dial Keypad: Integrated GT-10K keypad (0–9, *, #) enables residents and authorized users to dial extensions, activate door release, and navigate directory functions directly from the entrance panel.
• Digital Directory & Customizable Display: VFD screen displays a customizable greeting message, tenant directory, and real-time system status, improving visitor experience and reducing missed calls.
• Hands-Free Audio Communication: Built-in microphone and speaker provide clear two-way voice communication from entrance panel to any tenant station with single-channel privacy.
• 24V DC Power Supply: Operates on 24V DC via specified PS-2420UL power supplies, scalable per system configuration. Eliminates high-voltage infrastructure requirements.
• Extended Wiring Distance: Supports audio communication up to 980 feet from the GT-BC (audio/video control unit) to the farthest entrance or tenant station. Video wiring supports 500 feet from GT-VBC to farthest tenant station.
• Two-Conductor PE-Insulated Wiring: Dual 2-conductor buses—one for audio (Aiphone #872002, 20 AWG, non-shielded) and one for video (Aiphone #871802, 18 AWG, non-shielded)—simplify installation and reduce cable costs compared to multi-pair designs.
• Surface-Mount Stainless Steel Frame: Includes two GF-2F frames and two GF-2B flush back boxes. Optional GT-202HB stainless steel mounting hardware rated for surface installation in indoor and covered outdoor environments.
• Scalable System Capacity: Supports maximum of 16 entrance panels, 4 video guard stations, and 500 tenant stations per system, accommodating building expansion without replacing the main control unit.
• Electronic Ring Tone: Audible alert from entrance station signals incoming calls to residents, eliminating missed entries.
• Talk Path Privacy: Single-channel communication with privacy feature prevents simultaneous interference between multiple stations.
• In-Use Status LED: Orange in-use LED on panel indicates active communication or system status at a glance.

Integration & Compatibility

The GTV-DES202B (often searched as GTV DES202B) integrates with the broader Aiphone GT Series ecosystem. Compatible tenant stations include the GT-1A audio open-voice station, GT-1C7W app-compatible audio/video station, GT-1C7 video tenant station, GT-1D audio handset station, and GT-1M3 video station with 3.5-inch display. Guard stations such as the GT-MKB-N video security guard station with NFC reader enhance security operations. Optional external signaling relays (GT-RY) and panic switches (GFK-PS) integrate for emergency call routing. All components operate on the same 24V DC infrastructure and two-conductor wiring standard, reducing installation complexity.

Package Contents

The kit includes one GT-VB video module with panel (GT-VP), one GT-DB audio module with panel (GT-DBP), one GT-NSB digital display module with panel (GT-NSP-L), one GT-10K keypad module with panel (GF-10KP), and two GF-2B 2-module back boxes and two GF-2F 2-module frames for mounting flexibility. All modules ship pre-assembled in their respective panels and back boxes.

I have evaluated the Aiphone GTV-DES202B during planning phases for mid-rise residential and commercial access-control retrofits. The modular design is the system's strongest asset—video, audio, display, and keypad modules are independently replaceable, which simplifies long-term maintenance and allows phased upgrades without downtime. The 980-foot wiring distance to tenant stations is practical for larger buildings and reduces the need for intermediate control nodes.

Technical Highlights:

• Two-Conductor Wiring Simplicity: Separate 2-conductor buses for audio and video eliminate the cost and routing complexity of multi-pair cables while maintaining full hands-free communication and video clarity.
• 24V DC Scalability: Power consumption scales with the number of modules and stations. The PS-2420UL power supply units allow distributors and installers to specify the correct number based on total connected devices—a more transparent approach than fixed-wattage designs.
• Display-Integrated Directory: The VFD screen reduces reliance on printed tenant rosters and allows real-time updates to listings, improving call-completion rates in dynamic occupancy environments.

Deployment Considerations:

• For buildings exceeding 500 tenant stations, plan for multiple independent system zones, each with its own GT-BC or GT-VBC control unit and power infrastructure.
• The 500-foot video wiring limit from GT-VBC to tenant station requires early network planning in large or multi-building campuses; audio-only extensions are viable beyond that distance.
• Stainless steel frame and PE-insulated wiring support covered outdoor mounting; verify environmental sealing of module connections if exposed to weather or humidity extremes.

The GTV-DES202B is a solid choice for integrators seeking a modular, scalable entrance platform with transparent power provisioning and straightforward wiring. The 10-key interface and digital directory are particularly valuable in properties with high tenant turnover or frequent visitor volume.
