3-in-1 Entrance Station

The GT-DMB-N combines three major entrance-system functions into one factory-assembled panel:

Video Intercom

Provides wide-angle visitor video and hands-free audio communication.

Digital Tenant Directory

Allows visitors to search and select residents or businesses electronically.

Access Control

Provides both keypad-code and NFC credential entry for authorized users.

This eliminates the need to assemble separate camera, audio, directory, and keypad modules for many GT Series applications.

3.5-Inch Color LCD

The GT-DMB-N includes a 3.5" color LCD display.

The display can show:

• Tenant names

• Tenant numbers

• Building greeting

• Visitor instructions

• Calling information

• System status

• Programming menus

• Standby image

The LCD can also be configured for energy-saving operation.

Motion-Activated Display

A built-in motion sensor can automatically activate the LCD when a visitor approaches the entrance station.

This allows the display to remain in an energy-saving state when the entrance is not being used while still providing immediate instructions when someone approaches.

Digital Tenant Directory

The GT-DMB-N can store up to:

500 Tenant Names / Numbers

Programmable information can include:

• Resident name

• Company name

• Apartment number

• Suite number

• Alphanumeric room number

• Tenant dialing number

This makes the GT-DMB-N well suited for larger apartment, condominium, office, and mixed-use buildings.

Multiple Tenant Search Methods

Visitors can locate a tenant using several methods.

Alphabetical Scrolling

Scroll through tenant names alphabetically.

Jump Search

Jump through the directory by letter to reach the desired portion of the tenant list quickly.

Direct Dialing

Enter the tenant's assigned number directly using the built-in keypad.

Direct dialing is especially useful in large buildings with hundreds of directory entries.

Integrated Numeric Keypad

The GT-DMB-N includes a built-in keypad with:

• 0–9 numeric keys

•  

  • function key

•  

  function key

The keypad supports:

• Direct tenant dialing

• Access-code entry

• System programming functions

No separate GT-10K keypad module is required.

Keypad Access Control

Authorized residents, employees, or building personnel can enter a programmed access code to unlock the entrance without placing an intercom call.

Compatible configurations support up to:

500 Access-Control Entries

This allows the GT-DMB-N to function as both an intercom entrance station and basic credential-controlled entry point.

Integrated NFC Reader

The GT-DMB-N includes a built-in NFC reader.

Compatible NFC credentials can be registered to the station and used for door release.

Aiphone offers compatible credentials including:

• NFC-CARD – Access Card

• NFC-FOB – Access Key Fob

NFC-enabled devices can also be registered according to Aiphone's current programming procedures and compatibility requirements.

NFC Door Release

Once a compatible NFC credential has been registered, the user can present it at the NFC symbol on the GT-DMB-N.

The station verifies the registered credential and activates the door-release output when authorized.

This provides a convenient alternative to entering a numeric access code.

NFC Programming

The built-in NFC capability is also used for system configuration.

Aiphone supports configuration using an NFC-equipped compatible Android device and the:

Aiphone GT Setup Tool

Programming functions can include:

• Tenant information

• Access codes

• NFC credentials

• Welcome message

• Entrance settings

This can simplify directory updates compared with manually programming each field at the entrance.

USB PC Programming

The GT-DMB-N also supports programming from a compatible PC through USB.

PC programming can be used to load or update:

• Tenant directory information

• Access codes

• Welcome message

• System configuration data

This is useful for larger properties where substantial directory information needs to be managed.

170° Wide-Angle Camera

The GT-DMB-N incorporates a:

1/4" CMOS Camera

with an approximate field of view of:

170° Horizontal × 100° Vertical

Digital Pan / Tilt / Zoom

Compatible GT Series video tenant stations can manipulate the entrance image digitally.

Available functions can include:

• Wide view

• Zoom

• Digital pan

• Digital tilt

This allows residents to examine different portions of the entrance image without a mechanically moving camera.

This is useful at:

• Exterior entrances

• Parking entrances

• Covered vestibules

• Dim hallways

• Nighttime building entrances

Hands-Free Audio

GF-3B – 3-Module Back Box

The GF-3B is sold separately.

The GT-DMB-N mounts directly over the GF-3B to create a clean, low-profile entrance installation.
