System information
The Gira door communication system operates with the volt-
age type SELV.
With the audio control device, systems with up to 70 audio
devices can be realised in certain systems, e.g. 1 built-in
speaker with 5 add-on modules and 68 surface-mounted
hands-free feature home stations.
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)
i
Planning software
An exact determination of the maximum system size is possi-
ble with the planning software at www.gira.de.

5
Cable lengths for audio components
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 cou-
plers.
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 connec-
tion, as the polarity of the door communication bus is neutral.
Floor-call button (ET)
With home stations, any push button (NO contact) can be con-
nected 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.

13
Additional supply (ZV)
The ZV terminals have two functions:
1. Power supply of call button illumination at the door
stations. The call buttons are constantly illuminated at the
door stations. If the call button illumination is to be
switched off permanently, the jumpers between the bus
and ZV terminal must be removed.
2. Additional power supply for bus devices which can no
longer be powered via the 2-wire bus.
System
The flush-mounted 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.
i
Connecting an additional power supply
If an additional power supply is connected to the ZV termi-
nals, the jumpers must be removed.
i
Rubber plugs in the connectors
The "second" connectors are sealed with rubber plugs. These
plugs can be removed if necessary.

14
The audio control device
The audio control device is the main power supply of the Gira
door communication system.
The audio 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 of call button illumination (max. 15, the
number of call button illuminations that can be supplied is
dependent on the system size and the number of home
stations operation in parallel).
• provision of door opener control, including power supply
(12 V AC, 1.6 A) of the door opener.
• power supply of a TC-gateway.
• activation of the programming mode from the entire door
communication bus system.
Additional product features of the control device:
• maximum of 70 devices, e.g.
1 built-in speaker with 5 add-on modules,
68 surface-mounted home stations.
• depending on the system size, up to 3 home stations can be
operated.
• 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.
• adjustable activation time of door opener.

Displays and operating elements of audio control device
"Systemprog." button
By pressing the "Systemprog." button (for 3 s) the door com-
munication system is switched into the programming mode.
The yellow LED next to the programming button indicates 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
indicates 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 time (Türöffnerzeit). The yellow
LED next to the "Türöffnerprogr." button illuminates
during the switching time.

16
"Türöffnerzeit" adjuster
The activation time of the door opener is set at the "Türöffn-
erzeit" adjuster. The setting time lies in the range 1 second to
10 seconds. The potentiometer can be adjusted with a screw-
driver with a 3 mm blade.
"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 audio 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 20 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 "Systemprog.", "Türöff-
nerprogr." and "Überlast" LEDs flash.
The LEDs then flash for up to 180 seconds after the fault has
been eliminated.
