Build a digital tenant directory for an Aiphone GT Series entrance station with the Aiphone GT-NSB 3.5" Display Module.

The GT-NSB provides the visual interface for a modular GT Series digital entrance station, displaying the building's custom greeting message, tenant directory, dialing information, and system status.

Visitors can scroll alphabetically through the tenant directory using the integrated navigation buttons or, when the optional GT-10K keypad is installed, directly enter a tenant number for faster calling.

The GT-NSB supports digital-directory configurations with up to 500 tenant names and numbers, making it ideal for apartments, condominiums, commercial offices, mixed-use developments, and other large multi-tenant properties.

Digital Tenant Directory

The GT-NSB provides a digital directory that allows visitors to locate the appropriate apartment, office, or tenant without requiring a dedicated physical call button for every unit.

Compatible configurations can store up to:

500 Tenant Names / Numbers

Tenant records can include:

• Resident name

• Company name

• Apartment number

• Suite number

• Alphanumeric room number

• Assigned dialing number

This makes the GT-NSB especially useful in larger buildings where individual direct-select call buttons would require a very large entrance panel.

3.5-Inch Display

The GT-NSB incorporates a 3.5" display that can show:

• Building greeting

• Tenant names

• Tenant dialing numbers

• Search information

• System status

• Programming menus

The display provides visitors and installers with clear system feedback directly at the entrance station.

Tenant Search

Visitors can locate tenants using the buttons integrated with the GT-NSB.

Supported directory navigation includes:

Alphabetical Scrolling

Scroll forward or backward through the tenant list.

Jump Search

Jump through the directory by letter to locate a tenant more quickly.

Direct Dialing

When combined with the optional:

GT-10K – 10-Key Keypad Module

visitors can enter a tenant's assigned dialing number directly.

Integrated Navigation Controls

The GT-NSB includes controls for directory and programming operation.

Functions include:

• Back / previous search

• Forward / next search

• Call / confirm

• Cancel / return

These controls allow visitors to use the tenant directory even when a GT-10K keypad is not installed.

Custom Greeting Message

The GT-NSB can display a customizable welcome or building message.

Compatible digital-directory configurations support a scrolling greeting of up to approximately:

160 Characters

The scrolling speed can also be adjusted through system programming.

This can be used to display information such as:

• Building name

• Visitor instructions

• Property identification

• Entrance directions

• Access instructions

Direct Dialing with GT-10K

Add the:

GT-10K – 10-Key Keypad Module

to provide direct numeric tenant dialing.

A visitor can:

1. Locate the tenant's number

2. Enter the number on the GT-10K

3. Initiate the call

4. Communicate with the tenant

5. Wait for remote door release

This provides faster operation in large tenant directories.

Access Control with GT-10K

When paired with the GT-10K and compatible GT entrance electronics, the digital-directory system can also support authorized access-code entry.

Compatible configurations allow up to:

500 Unique Access Codes

Access codes can typically be configured as:

4 to 6 Digits

Authorized residents or staff can enter their code at the entrance to activate the system's door-release function.

The GT-NSB and GT-10K do not replace the actual door-release relay; that function is provided by the compatible GT entrance audio module.

GT-DB Audio Module

The GT-NSB connects to compatible GT Series audio equipment such as:

GT-DB – Audio & Door Release Module

or:

GT-DB-VN – Audio Module with NFC Reader

The audio module provides:

• Entrance microphone

• Entrance speaker

• Hands-free communication

• System audio/data

• Door-release relay

The GT-NSB connects to the compatible audio module with the supplied ribbon cable.

Door Release

The compatible GT-DB / GT-DB-VN provides a:

Form C Dry Contact Relay

rated up to:

24V AC/DC, 4A

This output can interface with suitable:

• Electric strikes

• Magnetic locks

• Gate operators

• Auxiliary access-control relays

The locking hardware is sold separately.

GT-NSP-L Cover Panel Required

The GT-NSB is the internal electronic display module.

For a typical modular entrance installation, pair it with:

GT-NSP-L – Cover Panel for GT-NSB

Component Relationship

GT-NSB = Internal display / directory electronics

GT-NSP-L = Exterior vandal-resistant cover panel

Both components are required for a finished modular entrance display section.

GT-NSP-L Panel

The GT-NSP-L exterior panel features:

• Zinc die-cast construction

• Transparent display window

• Vandal-resistant design

• IP43 protection

• Metallic finish

Panel dimensions:

Height: 3-3/4"
Width: 4-5/16"
Depth: 5/16"

The GT-NSP-L is sold separately.

24VDC Power

Unlike many of the system-powered entrance modules, the GT-NSB requires a dedicated:

24VDC Power Connection

Aiphone specifies use of the:

PS-2420UL – 24VDC, 2A Power Supply

according to the complete GT Series system configuration.

Maximum GT-NSB current consumption:

90mA

GT-NSB Power Wiring Distance

Aiphone's GT Series documentation allows up to approximately:

980 ft

between the GT-NSB and its applicable power supply using approved conductor sizes.

Actual maximum distance depends on:
