Fermax 9280 CITY DUOX Video Amplifier with Digital Keypad v3.0/18V
The Fermax 9280 video amplifier is the replacement module that operates as the audio and video core of Cityline DUOX entrance panels. It is supplied complete with its protective grille and without individual push-buttons.
It is designed for panels equipped with a digital keypad or Direct DUOX keypad, where calls are made by entering the apartment code. The module manages communication, video and calls from the building entrance.
This replacement is specifically intended for DUOX v3.0 and earlier panels with version 1.0 monitors. It should not be confused with current DUOX PLUS amplifiers or Cityline versions fitted with physical call buttons.

Practical applications of the Fermax 9280 video amplifier
Example 1: repairing a Cityline DUOX entrance panel with a digital keypad
In a residential building equipped with a Cityline DUOX v3.0 entrance panel, the installer detects faults affecting communication or video management while the keypad and external panel remain operational. The Fermax 9280 can replace the audiovisual core while retaining the existing digital keypad configuration and version 1.0 monitors.
Example 2: maintaining an entrance fitted with a Direct DUOX system
During maintenance of a Direct DUOX entrance panel, the technician needs to replace the amplifier without adding individual physical call buttons. The Fermax 9280 is suitable for this configuration because it includes the protective grille and allows apartment selection to remain managed through the compatible Direct DUOX keypad.
