Notes on the circuit diagram
l)
The internal wiring of the Classic
door station is completed on site by
the customer.
q)
Where there are more than 20
backlit call buttons, an additional
12 V AC supply, for instance
TR 603-…, must be installed due
to the current consumption. To use
the additional supply, the jumpers
between the CATLE and the call but
-
tons from b1/c1 to b/c are removed
and the b/c terminals are directly
connected to the additional supply.
The jumpers from the ACM camera
module to CATLE between the ter
-
minals V3/V4 and the terminals b1/
c1 remain as they are.

y)
The circuit diagram shows an
exemplary connection of call buttons
with the BRMA.
• The call button modules come in
designs with 1, 2, 3 and 4 buttons.
On all call button modules with
more than one button, all terminals
6… are internally bridged on the call
button module. The jumpers can be
removed if required.
•
If more than 4 call buttons are
required, the call button modules
are cascaded accordingly (e.g. 7 call
buttons = call button module with 4
and 3 call buttons).
• If there is more than one call
button module, then at least one of
the terminal 6… must be connected
straight through between all call
button modules.

Example:
In the case of 7 call but

tons, terminal 6.1 of the first call
button module is bridged with ter
-
minal 6.1 of the second call button
(see wiring diagram). Terminals 6…
are bridged with one another on
each call button module and do
not need to be additionally wired/
bridged (exception: A button is used
independently as a potential-free
contact and the jumpers have been
disconnected).
