Button Events
In input device mode, the factory setting, the coupler sends no DALI control commands of its own. It reports button events to a central DALI-2 controller, such as SmartCore, which decides what happens.
Each of the four inputs is one instance of type 1, push button, as defined in IEC 62386-301. The events below are the ones the standard defines and the coupler sends.
| Event | When it is sent |
|---|---|
| Button pressed | The button is pressed |
| Button released | The button is released |
| Short press | Pressed and released without a second press following quickly. With double press disabled, a quick press and release |
| Double press | Pressed and released, followed quickly by a second press |
| Long press start | Pressed and held |
| Long press repeat | Repeats at a set interval while the button stays held |
| Long press stop | The held button is released |
| Button stuck | The button has stayed pressed longer than expected |
| Button free | A stuck button has been released |
How these events are processed
Use input device mode whenever the installation has a central DALI-2 controller that supports IEC 62386-103. The controller holds the logic, which keeps the behaviour in one place and lets you change it without touching the coupler.
What you can do with these events
A central DALI-2 controller, such as the SmartCore, uses these events to switch lights on and off with a short press and dim them with a long press. The same events can also move blinds up, down and stop via the SmartCore relay outputs.
