Push-button interface


The push-button interface is used for connecting potential-free push buttons and NPN transistor outputs to the Niko Home Control installation. The interface converts the switching impulse of the push buttons into a Niko Home Control bus command.



The push-button interface sends a command when the push button is activated. The interface comes with bus voltage detection, which verifies that all communications with the Niko Home Control installation are functioning properly.

Potential-free push buttons connected via this push-button interface cannot be programmed manually. See Programming the installation manually in Controller ,Connected controller, or Connected controller light.


Connection  diagrams

  • Only connect the push-button interface to an SELV (safety extra-low voltage) contact and NOT to the 230 V        mains voltage.
  • Ensure that there is no contact between loose wires and other wires.
  • The cable length between the push-button interface and the push button or transistor output should not exceed 2 m.
  • The push-button interface can be used in an outdoor environment provided that the unit is fitted with splash- proof housing (e.g. New Hydro).

To  connect the push-button interface:

1    Connect the bus wire to the B screw terminals.

Loop to other control elements of the Niko Home Control installation if required.

2    Connect the potential-free push button or NPN transistor output.
