VIDEO SYSTEM WITH POWER SuPPLY 346000
- Max. 64 when traditional handsets and advanced handsets with local power supply are used
- Max. 50
if at least an advanced handset NOT in local supply is used
- Max. 3 handsets, bells or/and melodic bells for each apartment (max. 5 in one-family system)
- Max. 3 handsets, bells or/and melodic bells for each apartment interface

For the calculation of the size of the
system including interfaces item
346850 and 346851, separate the
galvanically insulated system The
following tables should be applied
for each galvanically insulated
system In doing so, during the first
approximation, the interfaces 386850
and 346851 should be treated as an
EP for the part connected to the TK
BUS of the video adapter 346830
or to IN of the audio/video node
F441, and as a handset for the part
connected to the HANDSET BUS
of the video adapter or to OUT of
the audio/video node If the tables
shows that the system CANNOT be
created with this approximation,
we
recommend that the YouDiagram
software is used to assess feasibility.
The number of handsets varies
depending on the number of the
entrance panels and the actuators
existing in the system
In the calculation of the handsets
which can be connected, we must
consider also any device (audio
handsets, video handsets, bells and
melodic bells) connected in parallel
AuDIO SYSTEMS EXAMPLE
In an audio system with an entrance
panel max 100 handsets can be
connected
For example we can connect:
„ „ 100 apartments with 1 handsets
(or apartment interface)
„ „ 80 apartments with 1 handsets (or
apartment interface) and 10 with 2
handsets (80+(10x2)=100)
„ „ 71 apartments with 1 handsets
(or apartment interface), 10 with
2 handsets, 2 with 3 handsets
and 1 actuator for generic loads
(71+(10x2)+(2x3)+3=100)
VIDEO SYSTEMS EXAMPLE
In a video system with an entrance
panel max 64 handsets can be
connected
For example we can connect:
„ „ 64 apartments with 1 handsets (or
apartment interface)
„ „ 50 apartments with 1 handsets (or
apartment interface) and 7 with 2
handsets (50+(7x2)=64)
„ „ 38 apartments with 1 handsets
(or apartment interface), 10 with
2 handsets, 1 with 3 handsets
and 1 actuator for generic loads
(38+(10x2)+(1x3)+3=64)
