Mounting
The group controller GC 612-... in
the 6-grid housing is used for the
connection of a group of max. 6 in-
house telephones HTC/HTCV 811-...
In-house telephones connected to
the group controller can be used
buttons 1/6 to call and communicate
with other in-house telephones. The
door station is switched off during
an internal call.
With the GC 612-... it is also
possible to signal a door call to more
than 2 in-house telephones. For this
function HTS/HTSV 811-... units can
also be used.
Several group controllers can be
used in an intercom unit.
In addition, switching and control
functions can be executed from
every connected in-house telephone
HTC/HTCV 811-...
If a door call is made to an in-house
telephone which is currently
conducting a call, this is interrupted
and an engaged signal sounds.
After replacing the receiver the door
call is signalled.

Speech connection
For each group controller, only one
call can be held. If an internal call
already exists within a group, it is
possible to place an additional call
from the door loudspeaker only to
another in-house telephone which is
not directly connected to the
GC 612-... The group controller acts
in relation to the 1+n side circuit
installation in the same way as an
in-house telephone. Each GC 612-...
requires the NG 602-... for its own
power supply.
Switching and control functions
• Switching and control functions
are possible in conjunction with the
SFC 602-... . A maximum of 6
control functions can be actuated
from each HTC/HTCV 811-... in the
group. Control functions can be
executed at any time with the
receiver down or during an existing
speech connection. Settings at DIL
switch 2 may be necessary in the
in-house telephones HTC/
HTCV 811-...
Operating elements GC 612-...:
• One programming switch in order
to enable the programming mode
• One status LED to display the
programming mode and saving.
• 8 DIL switches to determine the
required functions / for
programming.
• DIL switches 1–6 for assignment of
the door call to the in-house
telephones 1 to 6

at the door loudspeaker
OFF = Control functions 5 and 6
act on the SFC 602-...
at the group controller
Internal call

the group, each other in-house
telephone of the same group can
be called. The following procedure
has to be observed here: Pick up the
receiver and only then actuate the
required call button at the in-house
telephone.

potential-free contact S1/S2 is
available at the GC 612-...
(max. 24 V, 2 A).
