Bus distributor application
Camera branch: No bus distributor
required with a door station.
Monitor branch: No bus distributor
required when looping through from
bus telephone to bus telephone. The
integrated bus distributor in the bus
telephones is used.
Attenuation: No attenuation to be
considered.
BAA 650-... in the camera branch:
Connection of audio users (e.g.
BTLM 650-... or BTLE 050-...) or
users for switching and control
functions.
BAA 650-... in the monitor
branch: Connection of audio users
(BTS/BFS/BTC/BFC 850-...,
DCA 650-...) or users for switching
and control functions.
Attenuation: No attenuation to be
taken into consideration if
decoupled.
BVVS 650-... in the camera branch
More than one video door station
in the camera branch with “star
shaped” conductor routing.
BVVS 650-... in the monitor
branch: Within the In-Home bus:
Video more than one side circuit is
required.
Attenuation: The attenuation from
BVVS 650-..., BVVU 650-... and the
conductor length must be taken into
consideration.
BVVU 650-... in the camera
branch
More than one video door station
in the camera branch with “loop
through” conductor routing.
BVVU 650-... in the monitor
branch:
Connection of a bus telephone
with monitor to a side circuit with
“looped through” conductor
routing.
Attenuation: The attenuation from
BVVU 650-... and the conductor
length must be taken into consid-
eration.
Unconnected looping terminals in
the bus distributor BVVU 650-... and
BAA 650-... must always be termi-
nated with an RC element in order
to prevent disturbance to the bus.
