The Aiphone GT Digital apartment intercom system is the latest in the Aiphone range of apartment intercom systems. With the same architecture as the very popular Aiphone GH digital apartment intercom system the Aiphone GT apartment system offers the additional features of Hands Free as well as handset type room stations, Colour video with Pan/Tilt, audio hands free, expandable to sixteen main entrance stations, expandable to five hundred apartments and allowing up to four room stations to be installed per apartment.

A large range of apartment stations are available making it possible to provide either a fully featured system or just a basic apartment intercom system as required. Apartment stations are available in both video and audio models in both hands free and handset styles. Some models have picture recording and also allow up to four stations to be installed in an apartment with internal communication.  Apartment stations have some models also fitted with a hearing aid feature to help user with a hearing aid fitted with a T coil.

Video entrance panels feature 170 degree panoramic wide angle view enabling entrance stations to cater for wheelchair access and pedestrian access. Video entrance panels are available in a stylish flush mount stainless steel or semi flush or surface mounted vandal resistant steel. Audio entry panels are only available in steel.

Also entrance stations have audio and visual guidance to instruct visitors of the progress of their call.

Entrance panels can be either Direct Select using a single call button for each apartment or have a Digital Keypad to select the apartment number.

The GT2C and GT2CL enable you to connect a video entry station entry station so the apartment can have a video entry at the door of the apartment. A GTD or GTDL audio door station are also available to provide an audio only door station at the door of the apartment.

The apartment number on digital keypad entry panels can be programmed from from 1 to 999,999 and any letter from A to Z making the Aiphone GH suitable for single storey or multi storey complexes. Keypad entrance stations also allow for keyless entry by using the keypad to open the door with up to 500 entry codes in either 4, 5 or 6 digit numbers.

There are seven types of GT colour video apartment stations with two video apartment substations and two audio apartment stations available.

Different models can be intermixed in the same installation.

  1. Aiphone GT1C Colour video hands free apartment station with pan/tilt zoom feature.
  2. Aiphone GT1CL Colour video apartment station with pan/tilt zoom feature and hearing aid feature.
  3. Aiphone GT2C Colour video hands free apartment station with picture recording and pan/tilt zoom feature as well as local video door station input. (requires local 24V power supply)

  9. Aiphone GT1D Audio handset apartment station with hearing aid feature.

Note the GT system allows up to a maximum of 500 apartment stations in an expanded system. If more than one intercom station is installed in an apartment the total number of apartments is reduced. Though if the GT2C stations are used in conjunction with the GT2H substations up to 500 apartments can have up to four stations installed in each apartment. A local 24VDC power supply is required for each apartment in this case when GT2C stations are used. Number of power supplies required will be determined by the number of GT2C and GT2H stations installed.

The apartment stations are fitted with a service switch, this switch can be used to operate lift access in a standard system or local door release at the apartment.

Concierge stations can also be added to the system for installations in managed apartments or apartments which have a security desk. The Concierge can call apartments as well as receive calls from the apartments. Calls from the entrance stations can also be transferred to the Concierge if required after hours. The GT2C has the ability to call any of the four concierge stations separately.

The GT system is available in two formats.

  1. Aiphone GT Standard system which enables up to five entrance stations and up to forty eight apartment stations in either audio or video.
  2. Aiphone GT Expanded system which enables up to sixteen entrance stations and up to a total of five hundred apartment stations in either audio or video with lift interface.

The Aiphone GT expanded system has the added feature of programmable lift interface control by adding up to sixteen GTWLC lift interface modules. Each which have twenty relay outputs. Relays can be set as NO or NC and the operation time of the relays can be set from 1 to 600 seconds. Only name scroll type entrance panels should be used when a GTWLC is installed, do not install direct select entrance panels in this case.

For the installer the Aiphone GT system is easy to install with only two wires for an audio system and four for a video system. You can setup via a PC for systems with digital keypad entrances and have the ability to save all programming data to a PC. Connection to the PC is by the USB port, no more fiddling with RS232 converters and com port settings.

Apartment station addressing for the GT1C and GT2C apartment stations can be set by the dip switches on these apartment stations or by link programming as in the earlier GH system.  If addressing by the dip switches a digital keypad entry station must be used and it must be set up using the Aiphone software. The other GT apartment stations link setting is set by installation programming.

The Aiphone GT digital apartment system being a modular design enables systems to be configured to suit your exact installation requirements. Please contact us with your installation requirements and we will gladly configure an Aiphone GT system to suit your installation.

Note: the GT and GH systems have a certain amount of compatibility between some models. Please contact us with questions regarding compatibility. There is no compatibility between the GT and the GF systems.
