A perfect system for replenishments, avoiding possible connection errors

ALCAD's 2 WIRES non-polarized technology consists of an audio and / or video bus intercom based on a 2-wire infrastructure that allows the use of the cables of any installation (perfect for replenishment). Being non-polarized, it avoids possible connection errors, therefore facilitating the installation and accelerating its start-up, even in the changes from audio door entry systems to video intercom.

By having the largest variety of entrance panels and indoor units (monitors and handsets), it allows you to choose the aesthetics that best suit the needs of each situation.

The system allows up to 96 dwellings (with monitors and / or handsets) and up to 6 access points with push-button panels, and up to 2,000 dwellings using keypads.

The robustness and versatility of the system is wide since it allows installations through distributors and tap-offs or even in cascade.

Likewise, terminal programming is done from the main board for greater comfort.
