Combination button 3Plus designed as a master button for rear installation in Comelit audio and audio-video door stations, mailbox systems and door stations from third-party manufacturers up to a maximum material thickness of 2.5 mm. The button can be used in digital SB, SB2 and VIP systems. It consists of a nameplate (which can be changed on the front) and a call push button made of stainless steel, whereby the material and color are interchangeable (Art. 3060A in aluminum, Art. 3060B in brass). The brightness of the white LED can be adjusted on the back. Additional master buttons and up to three slave buttons (Art. 3061S) can be adapted to a master button using the included ribbon cable. If the installation takes place behind a metal plate smaller than 2.5 mm, an appropriate adapter must be used to compensate (not included in delivery).
