Installation topology
Figure 20 - Multi-family video door entry system
In the above examples, there is a single main power supply (AL) in the systems that use the single speech
unit (TE). If it is necessary to build a network of intercommunicating audio/video door entry units isolated from
the main system or if there are several external sources of audio-video signals (speech units with video cam-
era and voice unit) or if you want to create separated communication sectors or if there are systems already
installed in a building complex, then further supplementary modules will be needed such as:
• concentrators (CC);
• additional power supplies (AL1 and AS);
• separators (SP).
