Build or repair a direct-select Aiphone GT Series entrance station with the Aiphone GT-SW 4-Call Switch Module.

The GT-SW is the internal call-button switch module used behind compatible GF-1P, GF-2P, GF-3P, and GF-4P entrance panels. It supports up to four individual tenant call buttons, allowing visitors to directly call specific apartments, offices, or tenant stations from a modular GT Series entrance.

The GT-SW installs inside compatible GF-2F, GF-3F, or GT-4F front frames and connects with the other GT Series entrance modules to create customized multi-tenant entry systems.

Direct-Select Call Operation

The GT-SW provides the actual electrical switches used behind the tenant call-button panel.

A visitor presses the appropriate button and the GT Series system routes the call to the programmed tenant station associated with that call position.

One GT-SW can support up to:

• 1 call

• 2 calls

• 3 calls

• 4 calls

The visible number of call buttons depends on the front panel installed over the module.

Compatible Call Button Panels

The GT-SW is used with one of four interchangeable front panels:

GF-1P

1-Call Button Panel

Exposes one tenant call button.

GF-2P

2-Call Button Panel

Exposes two tenant call buttons.

GF-3P

3-Call Button Panel

Exposes three tenant call buttons.

GF-4P

4-Call Button Panel

Exposes all four available call buttons.

The button panel and GT-SW switch module are separate components.

Important: GT-SW vs. GF Call Panel

The GT-SW is the internal electronic switch module.

The GF-1P through GF-4P parts are the exterior panels installed over it.

For example:

GT-SW = Internal 4-call switch module
GF-4P = Exterior 4-button cover panel

Both components are required for a complete direct-select button assembly.

Modular GT Series Entrance Stations

The GT-SW is part of Aiphone's modular GT Series entrance-station architecture.

A custom entrance station can combine components such as:

• GT-DB or 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 digital directory

• GT-10K keypad

• GT-AD address module

• GF-BP blank panel

This modular design allows the entrance station to be configured for the exact building requirements.

Compatible Front Frames

The GT-SW mounts in compatible modular entrance frames including:

GF-2F

2-Module Front Frame

Suitable for compact two-module configurations.

GF-3F

3-Module Front Frame

Provides three vertically stacked module positions.

GT-4F

4-Module Front Frame

Provides four modular positions for larger custom entrance stations.

Compatible Back Boxes

Flush-mount installations can use corresponding back boxes including:

• GF-2B – 2-Module Back Box

• GF-3B – 3-Module Back Box

• GT-4B – 4-Module Back Box

Surface-mount installations use the appropriate GT Series hooded surface-mount enclosure instead.

Audio Entrance Configuration

A basic direct-select audio entrance can include:

• GT-DB or GT-DB-VN – Audio Module

• GT-DBP – Audio Module Panel

• GT-SW – Call Switch Module

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

This provides direct tenant calling and hands-free entrance communication.

Video Entrance Configuration

For video applications, add:

• GT-VB – Camera Module

• GT-VP – Camera Module Panel

The GT-SW remains responsible for the direct-select tenant call buttons.

Larger Multi-Tenant Configurations

Multiple GT-SW modules can be combined in larger entrance-station assemblies to provide additional direct-select call buttons.

For example:

• 1 GT-SW = up to 4 calls

• 2 GT-SW modules = up to 8 calls

• 3 GT-SW modules = up to 12 calls

Actual entrance capacity depends on the complete GT Series system design, frame configuration, and programming.

Wiring

Aiphone specifies GT Series wiring based on the function being carried.

Relevant wire families include:

Audio / Data

Aiphone #872002 Series

Examples:

• 87200250C – 20 AWG, 2-Conductor, 500'

• 87200210C – 20 AWG, 2-Conductor, 1,000'

• 872002P10C – 20 AWG, 2-Conductor, Plenum, 1,000'

Power / Applicable Entrance Connections

Aiphone #871802 Series

Examples:

• 87180250C – 18 AWG, 2-Conductor, 500'

• 87180210C – 18 AWG, 2-Conductor, 1,000'

• 871802P10C – 18 AWG, 2-Conductor, Plenum, 1,000'

Always follow the GT Series installation diagram for the exact entrance-station configuration.

IP43 Protection

The GT-SW carries an IP43 protection rating when used as intended within the compatible entrance assembly.

The complete entrance station's environmental performance depends on:

• Installed front panel

• Frame or enclosure

• Mounting method

• Complete system assembly

Always follow Aiphone's installation instructions for exterior applications.

Replacement for GF-SW

The GT-SW is the current replacement for the legacy:

GF-SW – GF Series 4-Call Switch Module

Aiphone retained compatibility with the familiar:

• GF-1P

• GF-2P

• GF-3P

• GF-4P

button panels.

When replacing a GF-SW in an older system, verify the complete entrance-station and system compatibility before installation.

Ideal Applications

• Apartment buildings

• Condominium complexes

• Multi-tenant properties

• Commercial office buildings

• Mixed-use developments

• Student housing

• Senior-living properties

• Controlled-access entrances

• GT Series entrance-station repairs

• Modular intercom system expansions
