System information
The Gira door communication system operates with the volt-
age type SELV.
In systems with video components, up to 28 home stations
and two door stations with colour cameras can be connected
to the 2-wire bus.
In systems with audio components, systems with up to
70 audio devices can be realised with certain system
configurations, e.g.
1 Built-in speaker with 5 add-on modules and
68 Surface-mounted hands-free feature home station.
Depending on the system size, a maximum of 3 home stations
can be operated in parallel per call button
A call-tone differentiation is made between the following calls
at the home stations:
• door call (initiated by call button)
• floor call (initiated by floor-call button)
• internal call (initiated by call button for home stations)
Cabling and cable arrangement
Cables with a wire diameter of 0.6 or 0.8 mm can be used as
bus lines.
The following cable types are suitable for use as bus lines:
• J-Y(ST)Y (communication line)
• YR (insulated bell wiring)
• A-2Y(L)2Y (communication cable)
Planning software
An exact determination of the maximum system size is
possible with the planning software at www.gira.de.
Cabling for new installation
We recommend communication line "J-Y(ST)Y" for new
installations of the Gira door communication system.

5
Cable lengths in video systems
The maximum cable length between the colour camera and
TFT display is 100 m.
Cable lengths in audio systems
The maximum total cable length (distributed among several
wiring sections) is 700 m.
A maximum of 30 devices may be connected to each wiring
section.
The maximum cable lengths of the individual sections (from
the control device to the last device) are dependent on the
cable diameter used. The guidelines for audio components
are:
• 0.6 mm diameter: 170 m
• 0.8 mm diameter: 300 m

Door communication bus coupler
The flush-mounted versions of the door and home stations are
connected to the 2-wire bus via door-communication bus
couplers.
The bus coupler has the following connections:
BUS
The devices are connected to the 2-wire bus via the BUS ter-
minals. Polarity need not be taken into account during con-
nection, as the polarity of the door communication bus is neu-
tral.
Floor-call button (ET)
With home stations, any push button (NO contact) can be
connected to the ET terminals as the floor-call button.
With the door stations, for example, a mechanical bell button
(NO contact) can be connected. This then acts like a call but-
ton from the Gira door communication system during start-up
and later operation.
The maximum cable length between the mechanical button
and the door-communication bus coupler is 20 m.
Bus coupler jumpers
The accompanying wire jumpers must be attached between
BUS and ZV at the bus coupler in order for the colour camera/
TFT display to operate. Therefore the call button illumination
at the door stations can not be switched off.

Additional supply (ZV)
The ZV terminals have two functions:
1. Power supply of call button illumination at the door sta-
tions.
The call buttons are constantly illuminated at the door sta-
tions with colour camera.
2. Additional power supply for bus devices which can no
longer be powered via the 2-wire bus. This could be a
third camera, for example.
The following connectors are also available:
System
The door communication inserts are connected to each other
with the 6-pole audio connection cable via these connectors.
Video
The door communication bus coupler is connected to the
flush-mounted inserts of the video devices, e.g. TFT colour
display, colour camera etc., via the 2-pole connector.
If an additional supply is connected,
remove the jumpers
If an external supply is connected to the ZV terminals, the
jumpers between ZV and BUS must be removed at the
respective bus coupler.
Rubber plugs in the connectors
The "second" connectors are sealed with rubber plugs. These
plugs can be removed if necessary.

13
The video control device
The video control device is the main power supply of the Gira
door communication system.
The video control device assumes the following tasks in the
Gira door communication system:
• provision of the bus voltage (26 V DC ± 2 V) for the door
communication system.
• Power supply for up to 2 colour cameras,
up to 4 colour cameras (2 with additional power supply) can
be operated per video control device.
• Power supply of call button illumination
(max. 15, the number of call button illuminations that can
be supplied is dependent on the system size and the num-
ber of home stations operation in parallel).
• provision of door opener control, including power supply
(12 V AC, 1.1 A) of the door opener.
• activation of the programming mode from the entire door
communication bus system.
Additional product features of the control device:
• In audio systems: Up to 70 audio devices, e.g.
1 built-in speaker with 5 add-on modules,
68 surface-mounted hands-free feature home station.
• In video systems: up to 28 home stations with TFT display
and two door stations with colour cameras, with max. three
parallel home stations, can be connected.
• Electronic overload and short-circuit protection.
• electronic excess-temperature protection.
• overload/short-circuit LED indicator.
• LED operation indication for determination of whether or
not mains voltage is active.
Parallel home stations with TFT display
If parallel home stations with TFT display are used, one dis-
play must be defined as the main display and the others as
secondary displays.

Displays and operating elements of video control device
"Betrieb" indicator
During trouble-free normal operation, only the green "Betrieb"
LED illuminates. It indicates that the device is being supplied
with power.
"Überlast" indicator
The video control device is equipped with an electronic over-
load protection which protects the electronics of the control
device against short-circuits and overloading on the bus line.
The overload protection is activated if, for example, the bus
line is short-circuited due to an installation error or too many
bus devices/bus loads are connected.
The red "Überlast" LED indicates both short-circuits and over-
loads. The flashing duration of the LED corresponds to the
time during which the bus voltage is deactivated when a fault
occurs. The LED then flashes for up to 5 seconds after the
fault has been eliminated.
With a permanent overload (or short-circuit), the bus voltage
is switched off for approx. 180 s after the third overload detec-
tion. During this switch-off phase, the "Systemprogr.",
"Türöffnerprogr." and "Überlast" LEDs flash.
The LEDs then flash for up to 180 seconds after the fault has
been eliminated.

16
"Systemprogr." button
If the "Systemprogr." button is pressed for 3 seconds, the
door communication system is switched to programming
mode. The yellow LED next to the programming button indi-
cates the active programming mode via flashing (see
Page 19).
"Türöffnerprogr." button
The "Türöffnerprogr." button has two functions:
1. Activating door-opener programming mode:
If the "Türöffnerprogr." button is pressed for 3 seconds
while the system is in programming mode, the door-
opener programming mode is activated (see Page 23).
The yellow LED next to the "Türöffnerprogr." button indi-
cates the active door-opener programming mode via
flashing.
2. Actuation of the connected door opener.
Briefly pressing the "Türöffnerprogr." button activates the
door opener for the set door opener time.
The yellow LED next to the "Türöffnerprogr." button
illuminates during the switching time.
"Türöffnerzeit" adjuster
The activation time of the door opener is set continuously at
the "Türöffnerzeit" adjuster. The setting time lies in the range
1 second to 10 seconds. The potentiometer can be adjusted
with a screwdriver with a 3 mm blade.
