Aiphone GTV-DES202B 10-Key Video Entrance Panel Kit
Overview
The Aiphone GTV-DES202B is a 2x2 modular video entrance station purpose-built for multi-tenant residential and commercial access control. This entrance panel combines video, hands-free audio, digital directory display, and a 10-key numeric keypad into a single swappable-module architecture. The GTV-DES202B (often searched as GTV DES202B) scales to 500 tenant stations, 16 entrance panels, and 4 concierge stations per system—making it suitable for mid-to-large apartment complexes, office buildings, and secured-entry facilities where flexibility and expansion matter.
Key Features
- Modular Construction: Four hot-swappable modules—video (GT-VB), audio (GT-DB), display (GT-NSB), and keypad (GT-10K)—eliminate board-level repair costs. If one module fails, replace only that component rather than the entire station. This reduces downtime and simplifies field inventory.
- 10-Key Numeric Keypad (GT-10K): Direct-dial access using 0–9, *, # buttons lets residents and authorized visitors ring extensions, trigger door release, and navigate the digital directory without a separate handset. Reduces visitor confusion and speeds check-in.
- VFD Digital Directory Display: Customizable greeting message and tenant directory on a vacuum-fluorescent display improve first-time visitor navigation and reduce missed or misdirected calls—important in buildings where staff turnover is high or directory changes are frequent.
- Two-Way Hands-Free Audio: Built-in microphone and speaker deliver clear voice communication from entrance to any tenant station with single-channel privacy—no external audio module required. Audio runs up to 980 feet from the control unit (GT-BC), supporting buildings with far-flung wings or multiple lobbies.
- 24V DC Power via Aiphone PS-2420UL Supply: Operates on low-voltage 24V DC, eliminating the need for 120V AC infrastructure at the entrance. This simplifies installation in retrofit scenarios and reduces electrician labor. Standard PS-2420UL supplies are scalable per system size.
- Extended Wiring Distance & Simplified Cabling: Audio communication reaches 980 feet; video reaches 500 feet from the control unit. Two-conductor twisted-pair buses (Aiphone #872002 for audio at 20 AWG, #871802 for video at 18 AWG) replace traditional multi-pair cables, cutting material costs and installation time—a real savings on large deployments.
- Stainless Steel Modular Mounting: Kit includes two GF-2F surface-mount frames and two GF-2B flush back boxes for indoor or covered outdoor installation. Optional GT-202HB hardware accommodates both surface and recessed mounting scenarios without redesign.
- Scalable System Capacity: Maximum 16 entrance panels, 4 video guard stations, and 500 tenant stations per system backbone. Buildings can expand without replacing the central control unit—a major advantage over fixed-capacity systems.
- Electronic Ring Tone & In-Use Status LED: Audible alert from the entrance panel signals incoming calls to eliminate missed entries. Orange in-use LED provides at-a-glance confirmation of active communication or system status, reducing support calls about 'is it working?'
- Single-Channel Privacy Talk Path: Prevents simultaneous interference between multiple stations during calls—essential in high-traffic lobbies where concurrency control keeps audio clear.
Integration & Compatibility
The GTV-DES202B integrates into the Aiphone GT Series ecosystem. Compatible tenant stations include the GT-1A audio open-voice, GT-1C7W app-compatible audio/video, GT-1C7 video tenant station, GT-1D audio handset, and GT-1M3 video station with 3.5-inch display. Guard stations such as the GT-MKB-N video security station with NFC reader add layered access control. Optional external signaling relays (GT-RY) and panic switches (GFK-PS) route emergency calls. All components operate on the same 24V DC backbone and two-conductor wiring standard, reducing cross-vendor integration complexity and lowering overall system cost.
What's in the Box
The kit includes one GTV-DES202B entrance panel with integrated 10-key keypad module, two GF-2F stainless steel surface-mount frames, and two GF-2B flush back boxes for modular installation flexibility.
Frequently Asked Questions
Q: What is the maximum distance audio and video can travel from the control unit?
A: Audio communication is supported up to 980 feet from the GT-BC control unit. Video is supported up to 500 feet from the GT-VBC. These distances assume proper twisted-pair wiring (Aiphone #872002 for audio, #871802 for video) and no significant EMI interference.
Q: Can I upgrade the GTV-DES202B modules if I need to add capabilities later?
A: Yes. The modular design allows you to swap individual modules (video, audio, display, keypad) without replacing the entire station. This is one of the key advantages for long-term flexibility and field maintenance.
Q: What power supply do I need for the GTV-DES202B?
A: The GTV-DES202B operates on 24V DC and requires Aiphone PS-2420UL power supplies. The number of supplies needed depends on your system size and total device count. Aiphone recommends sizing based on total current draw across all connected panels and stations.
Q: How many tenant stations and entrance panels can one system support?
A: A single Aiphone GT Series system backbone supports up to 500 tenant stations, 16 entrance panels, and 4 concierge/guard stations. This scalability is built in, so you can expand without replacing the central control unit.
Q: Does the GTV-DES202B support video from the entrance to tenant stations?
A: Yes. The GTV-DES202B includes a video module (GT-VB) that transmits a live video feed from the entrance. This feed can be routed to compatible tenant stations such as the GT-1C7 or GT-1M3 with video displays, allowing residents to see visitors before buzzing them in.
Q: Is the GTV-DES202B suitable for outdoor installation?
A: The GTV-DES202B is rated for covered outdoor environments when mounted with the optional GT-202HB stainless steel mounting hardware. It is not recommended for direct weathering (rain, snow, UV exposure). For fully outdoor entrance stations, consult Aiphone on weatherproof enclosure options.

The Aiphone GTV-DES202B modular entrance panel is a pragmatic choice for multi-tenant buildings where retrofit flexibility and long-term maintainability are non-negotiable. The four-module architecture means you're not locked into a single design—swapping the keypad, video, or display module after installation doesn't require core infrastructure changes. That matters when building code, tenant mix, or security policy shifts mid-deployment.
Technical Highlights:
- Two-Conductor Wiring Simplicity: Using Aiphone #872002 (audio, 20 AWG) and #871802 (video, 18 AWG) instead of multi-pair cables cuts material cost and installation labor significantly on large systems. For a 12-entrance deployment across multiple floors, this translates to hundreds of dollars in cabling alone.
- Extended Run Distances: Audio reaching 980 feet and video reaching 500 feet from their respective control units (GT-BC and GT-VBC) means you can handle larger buildings without intermediate repeaters or topology compromises. This is especially valuable in retrofits where running new conduit is prohibitively expensive.
- Scalable System Backbone: 500 tenant stations, 16 entrance panels, and 4 guard stations per system is a realistic ceiling for mid-to-large residential or office complexes. More importantly, you add panels and stations without replacing the central GT-BC or GT-VBC control unit—a major cost and downtime advantage over fixed-capacity competitors.
Deployment Considerations:
- 24V DC Infrastructure Required: You must provision PS-2420UL supplies for the system backbone. While 24V is simpler than 120V, it is still a dedicated power requirement. Budget accordingly in electrical design, and specify uninterruptible backup power if the building requires 24/7 entrance access during mains failure.
- Video Distance Limitation: The 500-foot video run is shorter than the 980-foot audio reach. In sprawling buildings, this may force you to deploy multiple video control units (GT-VBC) on separate backbone loops, adding complexity. Confirm building layout and conduit paths before committing to a single GTV-DES202B panel if video range is critical.
- Covered Outdoor Only: The stainless steel frame with GT-202HB hardware handles covered outdoor (eaves, portico) but not fully exposed weathering. Direct rain or snow will degrade electronics. For true outdoor lobbies, evaluate enclosure upgrades or Aiphone's purpose-built outdoor panels.
The GTV-DES202B fits best in multi-tenant residential (apartment complexes, condos) and mid-market office buildings where modular repair, long wiring runs, and phased expansion are realistic requirements. If your building is small (under 50 units) or fixed-size, simpler standalone intercoms may be cheaper upfront. If you need full IP-based access control with mobile app integration, explore Aiphone's app-compatible GT-1C7W stations alongside this panel. For hybrid deployments, the GTV-DES202B's video module (GT-VB) pairs cleanly with video tenant stations, enabling screen-and-buzz workflows without external middleware.
