4000 Series button expansion modules are used to achieve the required amount of call buttons for audio or audio/video door entry systems. Modules are available with 2, 3, 4 and 5 buttons. Double button modules are also available with 4, 6, 8 and 10 buttons, where 2 buttons share the same name plate window (add D after the number of the part code, e.g. 4844/BL becomes 4844D/BL with 8 buttons in a gun metal grey finish).
There are two variations of button modules available depending on the 4000 series audio or audio/video system being installed.
All the modules are available in a matt 316 marine grade stainless steel finish (suffix /M), mirror stainless steel finish (suffix /S) or gun metal grey (suffix /BL).
