Designed for the GF-3F

The GF-3B is the flush-mount back box designed to pair with the:

GF-3F – 3-Module Front Frame

Together, the GF-3B and GF-3F provide the mounting foundation for a customized three-module GT Series entrance station.

Compatible modules can then be selected according to the required system configuration.

Three-Module Capacity

The GF-3B provides recessed space for a vertical assembly containing up to three standard GT Series modular positions.

A typical entrance station might combine:

• Camera module

• Audio module

• Digital directory

• Call-button panel

• Keypad

• Access-control component

• Blank filler panel

The final configuration depends on the system design.

Compatible GT Series Modules

When used with the GF-3F front frame, compatible components can include select:

• GT-VB – Camera Module

• GT-DB – Audio Module

• GT-DB-VN – Audio Module with NFC Reader

• GT-NSB – Digital Display / Directory Module

• GT-10K – 10-Key Keypad

• GT-AD – Address Module

• GF-1P – 1-Call Button Panel

• GF-2P – 2-Call Button Panel

• GF-3P – 3-Call Button Panel

• GF-4P – 4-Call Button Panel

• GF-BP – Blank Filler Panel

Modules and front panels are sold separately unless specifically stated.

GT-DMB-N Application

The GF-3B is also the specified flush-mount back box for the:

GT-DMB-N – 3-in-1 Video Entrance Station with NFC Reader

The GT-DMB-N combines:

• Video camera

• Hands-free audio

• Digital tenant directory

• 10-digit keypad

• Access-control capability

• NFC programming

For flush-mounted GT-DMB-N installations, the GF-3B is sold separately and installed behind the entrance station.

Larger Entrance Station Configurations

Multiple GT Series back boxes can be installed side by side to create larger modular entrance stations.

Aiphone provides dimensional layouts for configurations using multiple back boxes.

Examples include:

• Single 3-module vertical entrance

• 2 x 3 module entrance

• 3 x 3 module entrance

• Larger custom modular entrance panels

When multiple back boxes are combined, follow Aiphone's spacing and joining requirements.

Flush-Mount Installation

The GF-3B is installed recessed into the wall before the entrance-station frame and modules are mounted.

Aiphone specifies that the back box should not be recessed more than approximately 9/16" behind the finished wall surface.

Proper positioning helps ensure the front frame and entrance modules fit correctly.

Surface-Mount Alternative

For applications where cutting a recessed opening is not practical, use the appropriate GT Series hooded surface-mount enclosure instead.

For a three-module vertical GF-3F configuration, the typical surface-mount option is:

GT-103HB – 3-Module Hooded Surface Mount Box

Important

When using the GT-103HB, the GF-3B flush back box is not used.

Self-Extinguishing ABS Construction

The GF-3B is manufactured from self-extinguishing ABS plastic.

This construction provides a durable recessed enclosure for:

• GT Series electronic modules

• Intercom wiring

• Power wiring

• Door-release wiring

• Access-control connections

Once installed, the back box is concealed behind the entrance-station front frame.

Ideal Applications

• Apartment buildings

• Condominium complexes

• Multi-tenant residential properties

• Commercial buildings

• Mixed-use developments

• Schools and universities

• Healthcare facilities

• Controlled-access entrances

• Video intercom systems
