Safety information
Electrical devices may only be installed and connected by a qualified electrician. Serious injury, fire or damage to property possible. Read and observe these instructions completely. These instructions are an integral component of the product and must remain with the end customer.
Intended use
– Provision of bus voltage (26 V DC ± 2 V) for the door communication system
– Control of up to 15 colour cameras (5 video door stations and 10 DCS camera
gateways),
– Power supply of
– up to 31 video devices (e.g. 28 home stations, 2 door stations with colour
camera, 1 DCS switching actuator)
– up to 70 audio devices
– up to 2 colour cameras (more with additional power supply)
– Call-button illumination (max. 15, the number of call-button illuminations
that can be supplied with power depends on the system size and the number of
home stations operated in parallel)
– Provision of the door opener control incl. power supply (12 V AC, 1,1 A) for
the door opener.
– Activation of the entire door communication bus system’s programming mode.
– Electronic overload, short-circuit and overtemperature protection.
– “Operation” LED indicator (mains voltage), overload/short circuit,
– Adjustable door opener activation time.
Assembly
For drip and splash-proof installation, mount the control device on a top-hat
rail in the distributor.
The mains and bus connection is made using screw terminals.
The mains connection must be made using an all-pole mains switch with a
contact opening of at least 3 mm.
The functional earth must be connected using a distributor block.
The control device’s ventilation slits must not be obstructed.
Electrical connections (Fig. 1)
L, N
Mains connection terminals L and N (AC 230 V, 50 Hz).
(Functional earth)
A functional earth is connected to this terminal for functional reasons.
Connect the earth potential to the earth terminal with a suitable line (not a
green/yellow line).
Bus
Power supply output of the Gira door communication bus with a regulated DC
voltage (26 V DC ± 2 V, 700 mA).
(Door opener output 230 V~/max. 2 A)
A door opener that cannot be connected to the “12 V~” terminals due to its
electrical values (e.g. very low-ohm or 24 V) can be connected to the
equipotential-bonding
relay contact with an external power supply (230 V~, max. 2 A).
Remove blank plug
Before connection, remove the blank plug from the terminal .
12 V~ (door opener output 12 V~ )
The 12 V~ output is used to supply power to and control the door opener (8–12
V, max. 1.1 A).
No permanent 12 V output
Power is not continuously supplied at the door opener output. The 12 V supply
at the door opener output is only active for the door opener time specified on
the setting controller.

Further information
Further information on application scenarios, system limits, topologies,
installationand start-up can be found in the “Systembasics for door
communication” in the Gira download area:
Operation
“System progr.” button
If the “System progr.” button is pressed for 3 s, the door communication
system is switched to programming mode. The yellow LED next to the programming
button
flashes to indicate that programming mode is active.
“Door-opener progr.” button
The “Door-opener progr.” button has two functions:
- Switch on door opener programming mode: If the “Door-opener progr.” button is pressed for 3 s while the system is in programming mode, the door opener programming mode is activated. The yellow LED next to the “Door-opener progr.” button flashes to indicate that door opener programming mode is active.
- Operation of the connected door opener. Briefly pressing the “Door-opener progr.” button activates the door opener for the set door opener time. The yellow LED next to the “Door-opener progr.” button lights up during the switching time.
“Door-opener time” setting controller The activation time of the door opener can be continuously adjusted using the “Dooropener time” setting controller. The adjustment time ranges from 1 s to 10 s. The potentiometer can be adjusted using a screwdriver with a 3 mm blade.
Indicators
“Operation” indicator
During fault-free normal operation, only the green “Operation” LED lights up.
It signals that the device is being supplied with mains voltage. “Overload”
indicator The video control device has electronic overload protection that
protects the electronics of the control device against short circuits and
overload on the bus line.The overload protection is activated if the bus line
is short-circuited due to an installation error, for example, or if too many
bus devices/bus loads have been connected. The red “Overload” LED signals both
a short circuit and an overload.
The length of time the LED flashes corresponds to the time that the bus
voltage is switched off in the event of an error. After the error has been
corrected, the LED continues to flash for up to 5 s. In case of a permanent
overload (or short circuit), the bus voltage is switched off for approx. 180 s
after the third overload is detected. During this switch-off phase, the
“System progr.”, “Door-opener progr.” and “Overload” LEDs flash. After the
error has been corrected, the LEDs continue to flash for up to 180 s.
