Application
Code lock as input unit for access
control and for making door calls.
Depending on the functional scope
of the access control and the
intercom system, further devices are
required for management and con
trol functions.
• LED as status indicator, only for
Vario (external potentialfree con
tact)
• Door release button for direct door
release via the EC 602...
• Control functions (e.g. roller shut
ters)
Electrical voltage
Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualified
electrician.
Range
The conductor network laid
throughout the entire Vario bus
must not exceed 2000 m. The loop
resistance (forward and return line
between the functional unit and
the control unit) must not exceed
20 Ohm. A core diameter of 0.8 mm
results in a range of appr. 260 m.
The power supply to the Vario
Bus components is provided by a
separate transformer TR 602.../
TR 603...
Programming
The CCOM 611... is programmed
via the corresponding auxiliary
device.
The procedure is described in the
corresponding programming instruc
tions.

Steps must be taken to ensure that
the supply voltage never exceeds
9 V AC at any device with maximum
current consumption.

Mounting and installation
1 Address setting
If several input/read units of the
same type (e.g. several COM 611...
and/or ST 10...) are used in a
system, a different address must be
set on each of the input/read units.
• Open the flap on the back with
the aid of a screwdriver.
• Set the address on the rotary
switch.
Addresses "0" and "9" are not
permitted!

Access
found in the system manual for the
door communication system, which
is supplied with the line rectifier/
server.
The code lock has a surface which
can show signs of use depending on
the user frequency. This results in
frequently used numbers standing
out optically from less frequently
used numbers. We therefore recom
mend changing the code at regular
intervals. Please use different num
bers.
Servicing
The functional unit can be com
pletely exchanged if required.
More detailed information on
module changing is provided in
the Classic door station installation
instructions.
