The 2N Door entry systems
(also home intercoms, access control,
door phones) are used for calling from
the entrance door to an office telephone.

They are a two-way communication devices (door phones, home intercoms, entry systems), which can be connected to any type of PBX (private branch exchange).

The 2N Door entry systems (home intercoms, access control, door phones) are connected to the PBX with a two-wire cable, so no special wiring is needed. They can replace traditional Speakerphone button bell panels and a complex system of distribution cables. 2N Door entry systems (door phones, home intercoms) do not need any power supply for their operation because they are powered from the telephone line.

The count of buttons is variable because 2N Door entry systems (home intercoms, access control, door phones) are modular systems. With the keypad, the entry system can be used as a button telephone and the required number can be either dialed or selected from 54 memories. The keypad and buttons can be combined; any undesired function can be disabled.

2N Door entry systems (door phones, home intercoms) are being produced also in "Antivandal version" (of strong vandal-proof materials). In order to watch the visitor standing in front of the entrance, it is recommended to utilize Video version with embedded colored camera - "Video doorphone".
