The Reduced Wiring - Electronic call video and audio intercom systems from ACI Farfisa.

If traditional analogue technology is preferred to digital, the reduced wiring solution is often the most suitable. Reduced wiring with electronic call provides a video intercom system using 4 common wires and one wire per call, 4+1 or an audio system with 1 common wire and one wire per call, 1+1.

The advantage is a notable simplification of the installation in comparison to traditional systems, with the assurance of basic functionality like lock release and the added security of viewing the door station camera without an active call (control-on switching).

Flexibility comes with a choice of the Agorà, Profilo and Matrix door stations, ZheroS and Exhito video and audio handsets.
