Systems may be installed using two different types of structures or modes of distribution:
• FREE SYSTEM;
• STAR SYSTEM.
The choice is based on installation needs, functions, and wall limitations.
The free wiring system is normally used for the traditional
distribution of power sockets. It is also suitable for My Home
Legrand systems, light and shutter automation, temperature
control and burglar alarm systems.
Star wiring is used for video intercom, sound, data
transmission, telephone, TV and SAT signal systems.
