Safety information
Electrical devices may only be
installed and connected by a qua-
lified electrician.
Serious injury, fire or damage to property
possible. Read and observe these instruc-
tions completely.
These instructions are an integral compo-
nent 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 vid-
eo 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 ad-
ditional 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 communica-
tion bus system's programming mode.
- Electronic overload, short-circuit and
overtemperature protection.
- "Operation" LED indicator (mains volt-
age), 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 ter-
minal for functional reasons.
Connect the earth potential to the earth ter-
minal with a suitable line (not a green/yel-
low line).
Bus
Power supply output of the Gira door com-
munication 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).
Functional earth
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.
