Aiphone GT-DBP Modular Entrance Panel
Overview
The Aiphone GT-DBP is a modular entrance panel engineered for integration with the GT-DB and GT-DB-VN audio modules in the GT Series intercom system. Built from zinc die-cast material, this panel provides a vandal-resistant mounting point for apartment and commercial entry applications. The GT-DBP supports multi-unit and large-scale intercom deployments where modular expandability and field integration are essential — you can add or replace panels without redesigning your entire entry infrastructure.
Key Features
- Zinc Die-Cast Housing: Vandal-resistant construction withstands weathering and deliberate impact in high-traffic entry environments. This matters in apartment buildings and commercial lobbies where panels are exposed to foot traffic and weather.
- Form C Dry Contact Door Release: Rated 24V AC/DC at 4A, enabling direct integration with electronic locks, magnetic locks, and access control systems. No relay module needed for standard electric strike or solenoid locks — one less component to maintain.
- GT-DB and GT-DB-VN Audio Module Compatibility: The panel pairs with both standard GT-DB modules and GT-DB-VN modules equipped with NFC readers, allowing flexibility in credential technologies. NFC-equipped variants support card and mobile-credential entry without hardware changes.
- 8MP Resolution Capability: When paired with compatible audio modules, the system delivers 8MP image capture at entry points — sufficient for facial recognition, license plate legibility, and incident documentation in most commercial and residential settings.
- 2-Conductor Wiring Support: Uses standard 2-conductor, solid, non-shielded PE insulation wiring (Aiphone #872002). This simplifies rough-in installation in retrofit projects where conduit space is limited and allows integration into existing wiring infrastructure without specialty cable runs.
- Modular GT Series Architecture: Designed to work within the quick-start installation methodology of the GT Series. You can configure single-panel or multi-panel installations and expand capacity by adding modules without replacing core infrastructure.
Integration and Deployment Considerations
The GT-DBP panel integrates into multi-tenant residential and commercial access control environments where modular system growth is anticipated. The 4A dry contact rating handles standard electric strikes and smaller solenoid locks directly; larger magnetic locks or dual locks may require an external relay module. The panel's zinc die-cast construction is suitable for covered entry vestibules and protected exterior locations, but you should verify weatherproofing requirements for your specific climate — the material resists corrosion but is not rated for direct salt spray or prolonged moisture immersion.
Installation follows the GT Series quick-start methodology, minimizing commissioning time. Coordinate wiring runs with your building's electrical and access control team to avoid conflicts with power and data cables.
Frequently Asked Questions
Q: Can the GT-DBP work with non-Aiphone audio modules?
A: No. The GT-DBP is designed specifically for the Aiphone GT-DB and GT-DB-VN modules. Pairing it with other manufacturers' modules will not work.
Q: What is the maximum number of GT-DBP panels I can deploy in a single system?
A: The GT Series supports modular expansion, but the exact maximum depends on your audio module configuration and wiring topology. Consult the GT Series Installation Guide or contact Aiphone technical support for your deployment scale.
Q: Does the GT-DBP include a power supply?
A: No. The panel draws power from the audio module it connects to. A separate 24V AC/DC power supply is required for the GT Series system as a whole, sized to support all modules and the door release actuator.
Q: Is the 24V dry contact relay suitable for magnetic locks?
A: The 4A relay can handle standard electric strikes and smaller solenoid locks. Larger magnetic locks (commonly rated 1200+ lb holding force) often exceed 4A. Verify your lock's current draw; if it exceeds 4A, use an external relay rated for the lock's inrush current (typically 5–8A).
Q: Can I retrofit GT-DBP into an existing intercom system?
A: Only if that system uses GT-DB or GT-DB-VN audio modules. If you have older Aiphone models, compatibility is not guaranteed. Confirm your current module type before ordering.

The Aiphone GT-DBP is a straightforward modular panel — no frills, solid engineering for multi-unit buildings. If you're planning a phased rollout or need to replace damaged panels in an existing GT Series deployment, the GT-DBP (also searched as GT DBP) handles both without system redesign.
Technical Highlights:
- 8MP Resolution: Paired with compatible audio modules, you get 8MP capture at entry points — enough for facial recognition at typical 4–6 foot distances and clear documentation of delivery packages or incidents. Not competitive with dedicated surveillance cameras, but sufficient for access control audit trails.
- 24V Dry Contact at 4A: Direct lock control eliminates the need for separate relay hardware on most electric strikes and smaller solenoids. Size matters here — if your lock draws 5A or more, budget an external relay ($30–60) in your BOM.
- Zinc Die-Cast Vandal Resistance: Withstands weathering and deliberate impact. Not IP67-rated, so it's not suitable for exposed outdoor installations without an additional protective enclosure — interior vestibules and covered porches only.
Deployment Considerations:
- The GT-DBP requires a GT-DB or GT-DB-VN audio module — there's no standalone panel version. Budget for the module cost in your project estimate.
- NFC-equipped GT-DB-VN variants are future-proofing; standard GT-DB modules are lower cost if you don't need card or mobile credentials immediately. Decide your credentialing strategy before spec'ing.
- 2-conductor wiring is simplicity for retrofit, but verify conduit routing and junction box availability in existing installations — rough-in changes can inflate labor costs.
Best fit: multi-tenant residential buildings, commercial office lobbies, and secured entry vestibules where phased system expansion is expected and you want modular panel replacement without full system downtime. Skip this if you need outdoor-rated enclosures (IP67) or anticipate lock currents above 4A without external relays.
