Hands-Free Communication

The GT-D provides open-voice hands-free audio communication between the person at the doorway and the connected Aiphone answering station.

Visitors simply press the call button to initiate a call.

The resident or staff member can then answer from the compatible indoor station and communicate without requiring the visitor to hold a handset.

Audio-Only Door Station

The GT-D does not contain a camera.

It is designed for installations where:

• Audio communication is sufficient

• Video identification is not required

• A secondary tenant doorway needs an intercom

• An existing compatible system requires a replacement audio door station

• A JP Series system requires an audio-only door option

Current JP Series Compatibility

Aiphone currently lists the GT-D as an audio door-station option for the JP Series.

Compatible primary equipment includes:

JP-4MED – 7" Video Master Station

The GT-D receives operating power directly from the connected JP Series master station.

A JP Series system can support multiple door stations depending on the complete system configuration.

JP Series Audio-Only Door Option

Although the JP Series is primarily a video intercom platform, the GT-D provides an economical audio-only entrance option.

A JP Series installation can combine compatible:

• JP video door stations

• GT-D audio door stations

• JP-4MED master station

• JP-4HD sub-master stations

This allows different entrances to use audio or video according to the requirements of each opening.

Legacy GT-2C Compatibility

The GT-D was originally designed as the personal tenant door station for the GT-2C video tenant master station.

In this configuration, the GT-D can be installed at an individual tenant doorway and call the tenant's:

• GT-2C master station

• Compatible GT-2H sub-master stations

The resident's applicable stations can be called simultaneously when a visitor activates the GT-D.

Legacy GT-MK Compatibility

Aiphone's current 2026 GT-D documentation also confirms compatibility with the legacy:

GT-MK – Security Guard / Manager Station

Verify the complete legacy system configuration before replacing or adding equipment.

Important Current GT Series Compatibility Note

The GT-D should not be assumed compatible with every current GT Series tenant or guard station simply because it carries the GT model prefix.

Aiphone's current documentation specifically identifies compatibility with:

• JP Series

• Legacy GT-2C

• Legacy GT-MK

For a current:

GT-MKB-N – Video Security Guard Station

Aiphone specifies the:

JO-DV – Video Door Station

rather than the GT-D.

Always confirm the existing system model before ordering.

Recommended Wiring

The GT-D uses:

2-Conductor, Solid, Non-Shielded, Low-Capacitance, PE-Insulated Cable

Recommended Aiphone cable includes:

• 87180250C – 18 AWG | 500'

• 87180210C – 18 AWG | 1,000'

• 871802P10C – 18 AWG | Plenum | 1,000'

JP Series Wiring Distance

When connected to a compatible:

JP-4MED Master Station

Aiphone specifies a maximum GT-D wiring distance of approximately:

330 ft

using approved #871802 wiring.

Always follow the current installation manual for conductor size and complete system layout.

Power

The GT-D does not normally require a separate local power supply.

Power is supplied through the compatible master or residential station.

For JP Series applications:

Power Source: JP-4MED

The GT-D itself does not require a PS-2420UL directly.

Door Release

The GT-D is primarily an audio communication door station.

Door-release capability, when required, is provided through the compatible Aiphone master system and appropriate relay / locking hardware—not by a high-current relay built into the GT-D.

JP Series door-release accessories may include:

• RY-1824L – Form C Door Release Relay

• RY-3DL – Selective Door Release Adaptor

• EL-12S – Electric Door Strike

Select door-control equipment according to the number of entrances and locking hardware requirements.

JPW-BA CCTV Integration

The GT-D can be combined with the:

JPW-BA – Long Distance / CCTV Camera Adaptor

in JP Series applications.

This allows an external analog CCTV camera to be used in conjunction with the GT-D audio door station, creating an audio intercom entrance with a separate camera source.

This is useful when:

• A specialty camera view is needed

• An existing CCTV camera is already installed

• The door location requires a different camera position

• A GT-D audio station is preferred for communication

KMB-45 Mullion Mounting Bracket

For narrow mounting locations, use the optional:

KMB-45 – 45° Mullion Mounting Bracket

The KMB-45 is compatible with:

• GT-D

• JP-DA

and provides an angled mounting solution for narrow frames or storefront-style installations.

SBX-CON1 Conduit Box

The optional:

SBX-CON1 – Surface-Mount Conduit Box

provides additional installation depth and conduit access for compatible stations including the GT-D.

This can be useful when wiring cannot be concealed inside the wall.

SBX-ACE Access Control Enclosure

The GT-D can also be installed with the:

SBX-ACE – Surface-Mount Access Control Enclosure

The SBX-ACE provides space for:

• One compatible Aiphone door station

• One separately installed access-control device

This allows the GT-D and equipment such as a card reader to be incorporated into one organized entrance assembly.

Surface-Mount Installation

The GT-D mounts directly to a suitable wall surface or over a:

Single-Gang Electrical Box

Its compact dimensions make it suitable for:

• Apartment doorways

• Office suite entrances

• Interior vestibules

• Secondary entrances

• Residential doors

• Narrow installation areas

Weather-Resistant Design

The GT-D is designed for applicable exterior door-station applications and is identified by Aiphone as weather resistant.

Always install the station according to Aiphone's mounting instructions and applicable electrical/building codes.

Ideal Applications

• Apartment tenant doors

• Condominium units

• Individual office suites

• Secondary entrances

• JP Series audio-only entrances

• Existing GT-2C systems

• Legacy GT-MK installations

• Residential entry communication

• Multi-tenant building upgrades

• Replacement Aiphone audio door stations
