Your official Tegui and BTicino distributor
The largest stock of Tegui and BTicino materials and spare parts in Europe.
The BTicino 8/2 Digital Riser Interface (ref. 346150) is the component that allows up to 8 independent floors to be connected to the 2-wire SCS main bus in BTicino/Tegui 2-wire video door entry systems. It acts as a vertical distributor between the floor bus and the building's main bus.
In buildings with several floors, each floor has its own secondary bus to which the apartment monitors are connected. The riser interface is the element that connects this floor bus to the building's main bus, managing communication between the entrance panel and the indoor monitors on each floor.
