Aiphone GTV-DES104B Modular

Aiphone GTV-DES104B Modular Video Entrance Panel Kit

Overview

The Aiphone GTV-DES104B is a 10-key modular video entrance station designed for multi-tenant and access control deployments. This 1x4 configuration combines video, audio, digital directory display, and keypad entry into a unified modular architecture, allowing integrators to build scalable door entry systems from standardized components. The GTV-DES104B supports up to 16 entrance stations per system and delivers hands-free communication from the entrance panel to tenant stations across wiring distances up to 980 feet for audio and 500 feet for video signals.

Key Features

• Modular Design: Combines GT-VB video module, GT-DB audio module, GT-NSB digital display module, and GT-10K keypad module in a single flush-mount assembly using the GT-4B back box and GT-4F frame for flexible deployment configurations.
• Video Capability: Integrated camera with LED illuminator and in-use indicator light for visual identification and call status feedback.
• Audio Module: Hands-free speaker and microphone communication from entrance panel to tenant station with electronic ring tone generation at the entrance station.
• Digital Directory Display: VFD screen displays customizable greeting message, tenant directory, and system status information for visitor wayfinding.
• 10-Key Keypad: Direct dialing and access control entry using 0–9, *, and # keys for unit selection and code entry.
• Guidance Indicators: LED indicators show door call-in status, active talk path, and door release activation state.
• Two-Conductor Wiring: Requires two sets of 2-conductor PE-insulated cable (Aiphone #872002 for audio, #871802 for video) with non-shielded construction for simplified installation.
• 24V DC Power: Operates from 24V DC using PS-2420UL power supplies; quantity determined by system configuration and load requirements.
• System Capacity: Supports maximum 16 entrance stations, 4 video guard stations, and 500 tenant stations per system, with up to 4 tenant stations per suite.
• Extended Wiring Distance: GT-BC backbone supports 980 feet to farthest entrance and tenant audio stations; GT-VBC video backbone supports 980 feet to entrance stations and 500 feet to video tenant stations.
• Stainless Steel Mounting: Surface mounting option with optional GT-104HB stainless steel surface mount enclosure for corrosion resistance.
• Single-Channel Communication: Talk path operates on single channel with privacy to prevent simultaneous calls on shared lines.

Integration & Compatibility

The GTV-DES104B integrates with the complete Aiphone GT series ecosystem of tenant stations, guard stations, and accessory modules. Compatible tenant station options include audio open-voice units (GT-1A), audio handset stations (GT-1D), and video stations with 3.5-inch (GT-1M3) or 7-inch (GT-1C7, GT-1C7W) displays. For security operations, the system supports video guard stations with optional NFC reader integration (GT-MKB-N). Auxiliary functions include external signaling relays (GT-RY) and panic switches (GFK-PS N/C) for emergency call routing. Audio modules are available with standard configuration (GT-DB, GT-DBP) or with integrated NFC reader option (GT-DB-VN) for credential-based access control.

Package Contents

The GTV-DES104B kit includes the following components: GT-VB video module with integrated camera and illuminator, GT-VP panel for video module, GT-DB audio module with speaker and microphone, GT-DBP panel for audio module, GT-NSB digital display module, GT-NSP-L panel for display module, GT-10K keypad module with 10-key interface, GF-10KP panel for keypad module, GT-4B 4-module back box, and GT-4F 4-module outer frame. Overall dimensions of the assembled panel are 16-¾ inches height × 5-5/16 inches width × 5/8 inches depth (outer panel dimensions, not including optional rain hood or surface mount bracket). All frame and back box hardware is included.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've worked with the Aiphone GT series in several multi-tenant and access control installations, and the GTV-DES104B modular design offers genuine flexibility for integrators. The modular approach means you're not locked into a single fixed form factor — you can configure video, audio, display, and keypad exactly as the deployment requires, and swap or upgrade individual modules later if needed. This matters in retrofit scenarios where panel space or electrical capacity varies building to building.

Technical Highlights:

• Wiring Infrastructure: Two separate 2-conductor buses (audio and video) with non-shielded PE-insulated cable simplifies cable runs compared to some competitors. The 980-foot backbone distance to entrance and audio tenant stations and 500-foot video distance covers most mid-rise and horizontal installations without repeaters.
• Module Flexibility: Video, audio, display, and keypad modules are discrete and field-swappable. If a customer later wants to add NFC reader capability, the GT-DB-VN audio module with NFC can replace the standard GT-DB without rewiring.
• System Scalability: 500-tenant-station capacity and support for 16 entrance panels across a single system backbone makes this suitable for larger properties. The 4-concierge-station limit is appropriate for security desk integration in commercial properties.

Deployment Considerations:

• Verify that PS-2420UL power supply sizing matches your total system load (entrance stations, tenant stations, guard stations, and relay modules). Undersizing power will cause intermittent audio/video dropout during peak calling periods.
• Cable runs over 980 feet (audio) or 500 feet (video) will require intermediate repeaters or secondary backbone infrastructure — confirm backbone topology before ordering.
• The 5-5/16-inch panel width is relatively compact and will fit standard single-gang mounting in most residential and light-commercial installations, but verify frame space in retrofit openings.

The GTV-DES104B is a solid choice for integrators who need modular entrance stations and want to standardize on Aiphone's GT ecosystem. It's not a turnkey solution — you're assembling and configuring modules — but that modularity is exactly the advantage for complex or phased deployments where fixed panels would create inflexibility.
