Bticino 2 Wire System Expansion Interface with 4 DIN Housing

Bticino 346851 2-Wire System Expansion Interface in 4 DIN Housing

The Bticino 346851 is a multi-mode system expansion interface housed in a 4 DIN modular enclosure for the 2-wire SCS BUS door entry system. It can double the length of the entrance panel to internal unit line, create risers with independent sound, and expand the performance of the apartment system.

The device regenerates the video signal over an additional 200 metres when used with the specified cable (336904). Up to 3 interface modules can be connected in cascade, providing a maximum video reach of 600 metres from the entrance panel to the furthest internal unit. The 346851 is configured using physical configurators via the M socket and mounts on standard DIN rail.
