The communications bus is formed by the three cables leaving
from terminal blocks 1M, 2M and 3M of the street panel audio
control group, which will be connected, respectively, to terminal
blocks 1M, 2M and 3M of the secondary street panel and the
telephones in the dwellings.
The connection between the street panel and the door opener is
executed through two cables (NO bushing insulators and – audio
control unit). Bushing insulators +12 and C are to be connected
between each other with a cable. An external push button can also
be connected to bushing insulators C and NO of the audio control
unit to activate the door opener. The activation time of the door
opener when the external push button is activated is not in timer
mode; that is to say, the door opener can only be activated when
the external push button is held down.
The following diagram shows the connections to be made between
the street panels of an installation with two blocks of dwellings with
two external accesses.
