LED recessed light for single or strip light applications. With integrated LiveLink WiFi control unit and LiveLink sensor for daylight-dependent control and presence detection as well as a WLAN module for secure commissioning and operation (WPA2 encryption). Predefined room configurations (use cases) with all planning-relevant data enable simple and quick commissioning. Control of up to 64 DALI participants. Commissioning is carried out using the LiveLink Install commissioning app for tablet PCs. LiveLink Sensor IR Micro for daylight-dependent control and presence detection. Constant light control with switch-off function when there is sufficient daylight. Passive infrared presence sensor, with highly sensitive multi-segment pyro sensors, with adjustable switch-off delay time, optionally in automatic mode (automatic on, automatic off) or semi-automatic mode (automatic off, manual on). Special IQ mode for automatically adjusting the run-on time to the use of the room. Electrical supply via the DALI interface of the control unit. Occupies 2 DALI participants. Square detection, presence detection squares max. 4 mx 4 m (16 m2) / radial max. 4 mx 4 m (16 m2) / tangential max. 6 mx 6 m (36 m2) with a recommended installation height of 2.8 m, permissible installation height 2.5 m to 4 m.
