Aiphone GTW-DP Distribution Point Terminal Strip
Overview
The Aiphone GTW-DP is a wall-mounted distribution point terminal strip engineered for centralized audio line routing in modular intercom installations. This accessory provides R1/R2 audio line termination and is built to support multi-unit deployments where reliable signal distribution across tenant stations is required. The GTW-DP integrates directly into the Aiphone GT series intercom platform, handling audio routing from a single distribution point rather than point-to-point wiring.
Key Features
- R1/R2 Audio Line Termination: Dual-channel audio termination eliminates the need for individual station wiring runs. Centralize all audio connections at one location, reducing cable clutter and simplifying troubleshooting when audio path issues arise.
- DIN Rail Mounting: Standard DIN rail design allows installation in equipment racks, wall-mounted cabinets, or control room panels. Secure mounting hardware is included, so you won't need to hunt for brackets or adapters.
- Multi-Unit Intercom Support: Works with audio tenant stations (GT-1A, GT-1D) and video tenant stations (GT-1C7, GT-1C7W, GT-1M3), making it adaptable across mixed deployments combining audio-only and video-capable units.
- Simplified Distribution: Consolidating audio lines at the GTW-DP reduces installation labor and point-of-failure risks in larger intercom networks. A single terminal strip replaces multiple independent connections.
Integration & Compatibility
The GTW-DP is designed for the GT series modular intercom platform. It pairs with audio stations (GT-1A, GT-1D) for voice-only deployments and video stations (GT-1C7, GT-1C7W, GT-1M3) for mixed audio/video environments. Installation uses the included DIN rail hardware and fits standard 35mm DIN rails, making it suitable for equipment rooms, electrical cabinets, or distributed control panels in warehouses, offices, and access control hubs.

When to Choose a Different Model
If your deployment is limited to one or two intercom stations and centralized audio distribution is unnecessary, standalone audio-only or video stations may eliminate the need for a separate terminal strip. Consult Aiphone's GT series product family to assess whether distributed or centralized audio architecture better fits your site layout and future expansion plans.
Frequently Asked Questions
Q: Does the GTW-DP work with older Aiphone intercom generations?
A: No. The GTW-DP is designed exclusively for the GT series modular platform. Consult product compatibility documentation if integrating with legacy Aiphone intercom lines.
Q: Can I install the GTW-DP horizontally on a wall instead of a DIN rail?
A: The included DIN rail mounting hardware is the supported installation method. Wall-mounting without the rail is not recommended and may compromise terminal access or cable strain relief.
Q: What is the maximum number of stations the GTW-DP can support?
A: Consult the Aiphone GT series system documentation for network topology limits. The GTW-DP itself is a distribution point and does not impose a per-station cap, but your overall GT system architecture will define scalability.
Q: Does the GTW-DP require power?
A: No. The GTW-DP is a passive terminal distribution strip and requires no separate power supply. It routes audio signals only.
Q: What is included for mounting?
A: DIN rail mounting hardware is included. No additional brackets or rails are shipped; you must supply or mount a standard 35mm DIN rail if one is not already in place.
Q: Can the GTW-DP be used outdoors?
A: The GTW-DP is designed for indoor installation in equipment rooms or cabinets. It is not rated for outdoor exposure and should not be mounted in direct sunlight or wet environments.

The GTW-DP is a passive, infrastructure-level accessory—not a device with processing power, but exactly the kind of workhorse that keeps multi-unit intercom deployments sane. If you're planning a GT series installation with more than two or three stations, centralizing audio termination at a single DIN rail point eliminates the rat's nest of individual wiring runs and makes future maintenance far less painful. The Aiphone GTW-DP (often searched as GTW DP) does one job: it collects R1/R2 audio lines and terminates them properly so stations can communicate without crosstalk or signal loss across the network.
Technical Highlights:
- R1/R2 Dual-Channel Termination: Handles audio routing for multiple stations simultaneously. Consolidating at a single point cuts installation labor roughly 30–40% compared to running individual lines to each station, and troubleshooting becomes straightforward—one central location to check signal path integrity.
- DIN Rail Form Factor: Standard 35mm DIN mounting is non-negotiable in modern control room design. The GTW-DP fits seamlessly into existing equipment racks, meaning you won't end up with an orphan accessory that doesn't integrate into your cabinet layout.
- Passive Design (No Power): Eliminates power supply complexity and failure modes. It routes audio only, so you're not adding another device to your UPS budget or creating a single point of power failure in your intercom network.
Deployment Considerations:
- The GTW-DP is GT series–specific. Do not assume compatibility with legacy Aiphone intercom platforms or third-party systems. Confirm your tenant stations are GT-1A, GT-1D, GT-1C7, GT-1C7W, or GT-1M3 before specifying.
- Watch the DIN rail substrate. If your equipment room cabinet doesn't already have a 35mm DIN rail, you'll need to source and install one separately—the GTW-DP hardware alone won't work on bare metal or generic shelving.
- This is a distribution point, not a switch or amplifier. If stations are far apart (50+ feet of cable runs), signal degradation depends on your cabling quality and topology, not the GTW-DP. Plan your audio backbone independently.
Deploy the GTW-DP in any GT series intercom network where you have four or more stations clustered in the same building or floor. The labor savings and maintenance clarity justify the minimal cost; you'll thank yourself the first time you need to isolate an audio issue and it takes minutes instead of hours.
