The FERMAX 6-Wire Spanish Intercom System is designed for reliable two-way audio communication between a building entrance and indoor units, with door-opening control available according to the installed system components. FERMAX offers 6-wire audio bus configurations within its MDS systems.

Full Description

The FERMAX 6-Wire Spanish Intercom System provides a practical solution for audio communication and access control in residential and commercial buildings.

FERMAX manufactures several intercom technologies and wiring configurations. In its MDS systems, FERMAX specifies a 6-wire audio bus, while its conventional 4+N audio systems use four common wires plus one call wire per home. Therefore, the exact wiring, power supply, terminals, and compatible components depend on the specific FERMAX system and model being installed.

The system can be used to establish two-way voice communication between the entrance panel and indoor telephone units and can support door-release functions when the appropriate door-lock and control components are included in the installation.

Technical Specifications

Important: FERMAX offers several different technologies, including MDS, 4+N, VDS, ADS, and BUS2. The exact operating voltage, terminal configuration, maximum distance, and compatible indoor/outdoor units cannot be confirmed from the product name alone. FERMAX documentation specifies 6-wire audio bus wiring for MDS and 4+N wiring as four common wires plus one call wire per home.
