Technical Features and System Compatibility
Integrated DF6000 Digital Decoding
Unlike standard analogue handsets that require complex multi-core wiring runs, the Farfisa EX312 contains built-in decoding circuitry engineered natively for the DF6000 digital protocol. Apartment address identification is set directly on the internal printed circuit board via hardware jumper bridges. This onboard intelligence eliminates the need for external decoding modules between the main riser and the handset, significantly reducing hardware costs and simplifying fault identification.
Effortless 2-Wire Installation Architecture
Designed specifically for the DF6000 bus system, the EX312 operates over a simplified 2-wire non-polarised infrastructure. This makes it an ideal audio handset choice for both new installations and retrofit projects where updating legacy wiring is impractical. The reduced wire count speeds up termination times for electrical engineers while ensuring stable, interference-free duplex speech communication between the main external entrance panel and internal residents.
Addressing and Engineering Guidelines
When replacing an existing unit or installing a new EX312 on a live DF6000 system, verify the jumper configurations match the specific address assigned to the apartment in the main door station’s database. Ensure all wiring connections are securely clamped to avoid signal loss on the digital data line. Always check that the system is powered down before altering onboard jumper pins to make sure the main controller registers the correct hardware address upon restart.
Maintenance and Replacement Information
As part of the modular Exhito range, the EX312 mounts directly onto flat interior walls using standard wall fixings. If you are retrofitting or replacing a damaged unit in a multi-tenant building, the EX312 provides a direct, like-for-like replacement without requiring central panel reprograming or modernising the entire block riser.
