Electronic Doorphones (Audio only): 4+N Analog, Digital and 2-Wire

The automatic doorphones, also called electronic door phones or telephones, are used to communicate between the interior and exterior of the house.

We have electronic doorphones for both single-family homes and neighborhood communities, analogue electronic doorphones and digital electronic doorphones. In our online store you can buy all-inclusive intercom kits at a reduced price. Fermax and Comelit have all kinds of solutions for any type of installation.

Older electronic door phones used 4+N analog systems, incorporating 4 common wires plus 1 additional wire for each home. Nowadays, we alson find digital door entry systems that can be settled with only 3 common wires, making the installation easier, reducing labour cost.

Both Fermax and Comelit have developed 2-wire digital systems, DUOX PLUS and SIMPLEBUS respectively. These systems offer greater simplicity in installation and great flexibility as they are compatible with any type of cables. They are ideal solutions to replace old doormen in single-family homes and communities.
