Aiphone GT Video-intercom System Guide
GT Door Stations
Are GT Door Stations different to GT Entrance Stations?
Yes. While GT entrance stations are located at the entrance to a building, set of
units, or office complex, and allow a visitor to contact any one of the many tenants,
GT door stations
●Are located immediately outside the tenant's door.
●Allow a visitor standing outside a tenant's door to contact that tenant only.
●Use different video intercom modules than entrance stations.
●Can replace old-style tenant door peep holes.
●Only work with Aiphone GT-2C master monitor stations.
A GT door station may only be used outside an apartment, unit, or office, if the GT
master monitor station used by that tenant is an Aiphone GT-2C. Other GT master
monitor stations do still however support a door bell button located immediately
outside the tenant's door (as does the GT-2C as well).
There are four different door stations that may be used with the GT video
intercom system.
Video intercom camera door stations from the single residence Aiphone JK Series
may be used with the GT-2C master monitor station, when placed immediately
outside the tenant's door. Choose from the flush mount stainless steel plate JK-DVF
door station, the JK-DV surface mount zinc die-cast (left) door station, or the plastic
surface mount JK-DA. All of these JK door stations feature a 170° wide angle digital
PTZ camera, similar to that used in the GT video intercom entrance stations.
If the tenant requires an audio-only door station, then the Aiphone GT-D door
station may be used.

Aiphone GT Video-intercom System Guide
Internal Tenant Stations
Master monitor stations have the capability to support up to three additional
sub-master monitor stations, or monitor stations, within the same tenant's
apartment, unit, or office.
Sub-master monitor stations must work in conjunction with a master monitor
station.
Monitor stations may be used on their own if the tenant only requires only one
station inside, or as more economical (but less capable) master and sub-master
monitor stations if the tenant requires more than one station.
There are two Aiphone GT master monitor stations, the GT-2C and the GT-1C.
The GT- C master monitor station would be most
tenant's first choice. The GT-2C features include
(blue-highlighted features are unique to this
monitor)
●Up to 4 video-intercom monitor stations
per tenant; one GT-2C plus up to three GT-
H sub-master monitor stations.
●All four monitor stations are powered by a
local power supply in the apartment. (One
24VDC 2A power supply may power 4 adjacent tenants with GT-2Cs and no
sub-master stations, or two adjacent tenants with sub-master monitors.)
●Support for a tenant door station for better security and elimination of the
old-style peep hole.
●Support for a tenant door bell button.
●Digital PTZ (Pan-Tilt-Zoom) viewing of 170°
wide angle camera views from entrance
stations or a local door station.

tenant names, locations, and access codes for your Aiphone GT multi-tenant video
intercom system easier. This free software may be downloaded from
http //www.cleverhome.com.au/software/Aiphone-GT-video-intercom-setup-
software.zip
Your Windows PC connects to your Aiphone GT multi-tenant video intercom by
USB cable to the GT-NS-V/GT-NS Name Scrolling entrance display module, the GT-
DMV/GT-DM integrated entrance station, or the GT-MK concierge/guard station.
Alternatively, all of the above stations may be programmed manually directly at the
stations – the PC software simply provides a more productive way of managing
tenant information for your GF video intercom system.

GT Monitor Station Option Connectors
GT monitor stations have one or two Options connectors on their back, which have
the pin-outs and functions identified below.
Door Bell input allows a door bell button located immediately outside the tenant's
door to be connected to the tenant's master monitor station. The door bell should
have contacts that are normally open, and be non-latching (momentary action).
Emergency Alarm Input allows connection of a switch to generate a security
alarm. Switch contacts should be normally closed, and be latching.
Security/Utility inputs 1 to 3 allow connection of security sensors or switches for
Aiphone Security Suite support, or other utility functions.
Doctor Call Input allows connection to a switch to automatically allow entry of a
doctor or other emergency service. generate a security alarm. Switch contacts
should be normally closed, and be latching.
Option Contact output may be used to activate lights or an external call buzzer,
using the GT-RY relay to buffer the Option Contact output.
Video Out output provides an NTSC direct video signal for displays <3m away.
Only live video is sent to the Video Output, there is no video output when viewing
previously recorded pictures, or menu pages. CCTV integration support is
provided by via this NTSC video output, and Display Transfer output relay
contacts that may be used to activate external monitors via an optional GT-RY
external signalling relay. Both of these outputs are accessed using the 4 pin option
connector on the back of the GT-2C master stations. This connector is not provided
with the GT-2C, even though the 12 pin option connector is.

outer protective jacket, a must be used for audio and video distribution wiring for
any GT installation. The most readily obtainable PE cable is 0.9mm. There is a
table in the GT video-intercom installation manual indicating the maximum cable
distances between all GT modules – you should refer to the 0.8mm column in this
table if 0.9mm PE cable is being used in the installation.

Aiphone GT Video-intercom System Guide
GT Standard Configuration
The Standard Configuration for a GT video-intercom system is illustrated below.
The configuration from the residence (or tenant) trunk lines to the tenant monitor
stations is the same for the Standard and the Expanded Configurations, and is
illustrated is a subsequent section.
The video output from the video entrance station is connected to the GT-VBC Video
Bus Control Unit, which has 6 trunk line outputs.
The audio and control output from the entrance station is connected to the GT-RC
Bus Control Unit, and then out to 6 trunk lines from a Distribution Point (that must
be provided by the installer).
The separation of the video and audio/control distribution allows an audio
intercom-only system to be implemented by omitting the video component of the
modular entrance station, the GT-VBC, and all of the video distribution cabling.
There is a table in the GT video-intercom installation manual indicating the
maximum cable distances between all GT modules, depending upon the gauge of
PE cable used. The 0.8mm column should be used from this table if 0.9mm PE
cable is being used in the installation.
While only one modular entrance station is shown above, any of the modular
entrance stations, or the integrated entrance station may be used. Also, multiple
entrance and concierge stations are supported, as indicated in the “Maximum
Supported Modules” table above.

Aiphone GT Video-intercom System Guide
GT Expanded Configuration
The Expanded Configuration GT system uses the GT-VBX Expanded Video Bus
Control Unit and the GT-BCX Expanded Bus Control Unit to provide 4 additional
sub trunk lines, allowing up to 4 sets of GT-VBC and GT-BC control units (the same
units used in a Standard Configuration GT system) to be used instead of just one
set. The GT-VBX and GT-BCX must be mounted adjacent to each other, as their
interconnecting cable is only 40cm long.
Two additional GT-BC Bus Control Units are also able to be used to provide two
sets of trunk lines for entrance stations and concierge/security guard stations.
