This presence detector is a DALI-2 secondary and BMS detector that extends the detection range of a DALI master detector or as part of a BMS system. It is designed for surface mounting and has an IP54 protection degree. If the secondary detector is connected to a DALI bus with a DALI master, it will start communicating with this master without further commissioning. If it is connected to a DALI bus or a BMS system, the detector needs to be commissioned with the BMS software. The detector’s settings can be modified using the Niko detector tool app and 2-way Bluetooth® communication between a smartphone and the detector or using the BMS software.
