Surface mount a three-module Aiphone GT Series entrance station while adding weather protection with the Aiphone GT-103HB 3-Module Hooded Surface Mount Box.

Designed for use with the GF-3F 3-Module Front Frame, the GT-103HB provides the enclosure, wiring space, and protective hood needed to install a 1×3 modular GT Series entrance station directly to a wall without using the recessed GF-3B back box.

The 3-module capacity makes the GT-103HB particularly useful for complete audio, video, and direct-select or digital-directory entrance configurations.

Designed for the GF-3F Front Frame

The GT-103HB is designed for use with the:

GF-3F – 3-Module Front Frame

The GF-3F holds three standard GT Series modular panels in a vertical arrangement.

Component Relationship

GT-103HB = Hooded surface-mount enclosure

GF-3F = 3-module front frame

GT Series Modules & Panels = Installed within the GF-3F assembly

Together, these parts create a complete surface-mounted 1×3 GT Series entrance station.

No GF-3B Back Box Required

For a standard flush-mounted GF-3F entrance, Aiphone uses the:

GF-3B – 3-Module Back Box

When surface mounting with the GT-103HB, the enclosure takes the place of the recessed back box.

Typical installation:

1. Mount the GT-103HB directly to the wall

2. Route the required wiring into the enclosure

3. Install the GT Series modules and panels

4. Attach the GF-3F front frame to complete the entrance assembly

A GF-3B is not required inside the GT-103HB.

Hooded Weather Protection

Aiphone's hooded GT Series surface boxes provide additional protection for entrance equipment exposed to weather.

The GT-103HB hood helps reduce direct exposure to:

• Rain

• Dripping water

• Snow

• Exterior moisture

• Incidental weather

The enclosure also extends beyond the entrance panel, helping shield the modular components from direct precipitation.

Moisture Drainage

Openings at the bottom of the GT-103HB allow accumulated moisture to drain away from the entrance-station components.

Do not block these drainage openings during installation.

Interior Wiring Space

The GT-103HB provides space behind the modular entrance components for:

• Audio/data wiring

• Video wiring

• Power wiring

• Door-release wiring

• Module interconnections

• Access-control wiring

Its 2-11/16" overall depth makes it particularly useful for retrofit installations where wiring cannot be recessed deeply into the wall.

Three-Module Capacity

The GT-103HB accommodates a GF-3F 3-module front frame, providing three vertically arranged module positions.

This allows several common GT entrance configurations.

Three-Module Video Entrance

A common direct-select video entrance can include:

• GT-VB – Camera Module

• GT-VP – Camera Panel

• GT-DB or GT-DB-VN – Audio Module

• GT-DBP – Audio Panel

• GT-SW – Call Switch Module

• GF-1P / GF-2P / GF-3P / GF-4P – Call Button Panel

The GT-103HB provides the surface-mount enclosure for the entire three-module assembly.

Digital Directory Audio Entrance

The GT-103HB is also the specified surface-mount option for configurations such as the:

GTA-DESB – 10-Key Audio Entrance Panel Kit

A typical 3-module digital-directory audio entrance uses:

• GT-DB – Audio Module

• GT-DBP – Audio Panel

• GT-NSB – Digital Directory Module

• GT-NSP-L – Display Panel

• GT-10K – 10-Key Keypad

• GF-10KP – Keypad Panel

• GF-3F – 3-Module Front Frame

This provides:

• Hands-free audio

• Digital tenant directory

• Direct tenant dialing

• Access-code entry

• Remote door release

Compact Video Entrance

A three-position configuration can also combine:

• GT-VB + GT-VP – Video

• GT-DB / GT-DB-VN + GT-DBP – Audio

• GT-SW + GF Call Panel – Direct Tenant Calling

This is a common choice for smaller apartment, condominium, or office entrances.

Compatible Modules & Panels

Depending on the system design, the GT-103HB/GF-3F assembly can accept combinations of components including:

• GT-VB – Camera Module

• GT-VP – Camera Panel

• GT-DB – Audio Module

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

• GT-DBP – Audio Module Panel

• GT-SW – 4-Call Switch Module

• GF-1P – 1-Call Panel

• GF-2P – 2-Call Panel

• GF-3P – 3-Call Panel

• GF-4P – 4-Call Panel

• GT-NSB – Digital Display / Directory Module

• GT-NSP-L – Digital Display Panel

• GT-10K – 10-Key Keypad

• GF-10KP – Keypad Panel

• GF-BP – Blank Filler Panel

The exact module combination depends on the entrance-station design.

Surface Mount vs. Flush Mount

GT-103HB Surface Mount

Use the GT-103HB when:

• Recessing the entrance station is not practical

• Existing construction limits wall-cavity access

• Additional wiring space is needed

• A retrofit entrance is being installed

• Added weather protection is desirable

GF-3B Flush Mount

Use the GF-3B when:

• A recessed installation is desired

• The wall can accommodate the back box

• A lower-profile finished entrance is preferred

Both configurations use the:

GF-3F – 3-Module Front Frame

GT-103HB vs. GT-103H

Do not confuse the GT-103HB with the legacy:

GT-103H – 3-Module Rain Hood

GT-103HB

Complete hooded surface-mount enclosure approximately 2-11/16" deep.

GT-103H

Shallow rain hood used with a GF-3F + GF-3B flush-mounted entrance.

The GT-103H is discontinued, while the GT-103HB remains the current 3-module hooded surface-mount box.

• Mixed-use developments

• Multi-tenant residential buildings

• Student housing

• Senior-living facilities

The following are sold separately unless specifically stated:

• GF-3F front frame

• GT-DB / GT-DB-VN audio module

• GT-DBP audio panel

• GT-VB camera module

• GT-VP camera panel

• GT-SW call switch module

• GF call-button panel

• GT-NSB display module
