7.1. What Is LLI

A Low-Level Interface makes use of a dry contact in order to detect voltage/current changes similar to the opening and closing of a relay. It can simply be thought of as binary input where the opening and closing of a relay can trigger different control events.

As an example, the opening and closing of a contact is able to trigger a lighting control preset such as “Scene 7” for Response SN3/s. This means Response SN3 can now directly integrate with third-party compliant DALI-2 input switches. A change in the switch state will be read as an input for Response SN3s over DALI. Instead of checking the state continuously the bus is reserved for lighting control messages.

No additional steps are involved in setting up a low-level interface for your Organic Response installation. All you require is a Response SN3 3 with the latest firmware version and a DALI-2 compliant switch input connected to the DALI bus.
