Duo
The Duo digital video and audio door entry systems from ACI Farfisa continue to evolve, with the advent of the GW2IP gateway allowing calls and remote access control without limits of distance.
With increases in the number of users, greater integration and ease of installation, The Duo System has further enhanced its strengths: quick and easy assembly, competitive performance and features. DUO SYSTEM is compatible with many internal and external station lines and with the PDX2000 concierge station.
Among the available accessories, the technical development of the 2231 line buffer has allowed a major upgrade in the number of possible users, now up to 20,000. Duo System is now also a “pure” 2-wire system, thanks to the ALBA, SOLVO and AGORÀ push-button stations. As with all the other components which use this technology, power is delivered directly over the 2-wire bus, therefore making it possible to further optimise the installation. The ever-increasing demand for enhanced performance has been met.
