1.5 Connection of expansion modules VBD10(5)-mod
The VBD10-mod call button expansion modules come with ten call
buttons and the VBD5-mod call button expansion modules come with with five
call buttons. However, the way of numbering is crucial. The physical connection
can be random, you can interconnect the modules as you wish on regardless of
the numbering!
The numbering of call button modules will be explained later on. The
numbering is setup on each call button module using the DIP switch (E6) .
The VBDx-mod electronics board only connects to the original A-
VarioBell key module by means of the terminal block (E5) and the
interconnecting three-wire cable (E4) . The connector (E7) is not used with IP-
VarioBell.
The connection is made using K1 flat cable (two black connectors at
both ends) and the K0 cable only serves as a connection between the base
module and the first button module or keypad (on the one side orange and on
the other side the black connector).
(E1) is a connection to the
basic module (K0 cable) or
connection to the previous button
module (cable K1),
(E2) is the
connection of the following button
module (K1 cable),
(E3) is the
connection between the call button
modules (cable K1)
