SR-2422NK4-DA2 4-fold button DALI-2

Sunricher SR-2422NK4-DA2 is an elegant 4-fold wall button with certification DALI-2, intended for lighting control via a compatible DALI-2 application controller. It features a minimalist design, low profile and metal casing, making it suitable for modern homes, offices, hotels and commercial spaces.

The device has 4 programmable buttons and 8 programmable LED indicators, which provide visual feedback according to system configuration. Individual buttons can be assigned functions such as switching the lighting on and off, dimming, controlling groups of lamps or calling up light scenes.

Certified DALI-2 input device

The SR-2422NK4-DA2 is a certified DALI-2 input device according to standards IEC 62386-101, IEC 62386-103, IEC 62386-301 and IEC 62386-332.

The button acts as a DALI-2 Input Device, meaning it sends button press events to a compatible application controller. It then processes the events and sends the relevant DALI commands to the lamps or dimmers.

Unlike separate DALI controllers therefore it does not control DALI dimmers directly without an application controller.

Programmable buttons and LED indication

Four buttons allow flexible adaptation of functions according to the requirements of a specific installation. Depending on the capabilities of the application controller, various button press reactions can be configured, including brightness control and light scenes.

Eight LED indicators provides feedback on control status. Their behavior can be adapted to the configuration of the DALI-2 system.

Multi-Master communication support

Thanks for the support Multi-Master several compatible pushbutton controllers and other DALI-2 input devices can be connected to one DALI bus.

This makes it possible to create larger lighting systems with multiple control points without the need for a separate line for each wall controller.

Configuration of the functions is performed via a compatible DALI-2 application controller.

Power supply directly from the DALI bus

SR-2422NK4-DA2 is powered directly from DALI buses and does not require a separate power source or connection to a 230 V mains voltage.

A typical take-off from the bus is only 2 mA, while the maximum consumption reaches 10 mA. When designing a DALI system, it is necessary to take into account the total consumption of all connected devices.
