This presence detector is a DALI 2 secondary and BMS detector that extends the detection range of a DALI master detector or can be part of a BMS system. It is designed for surface mounting and has protection class IP54. If the secondary detector is connected to a DALI bus with a DALI master detector, it begins to communicate with this master detector without further commissioning. If it is connected to a DALI bus or a BMS system, the detector must be commissioned with the BMS software. The detector settings can be changed via the Niko Detector Tool app and the 2-way Bluetooth® communication between smartphone and detector or using the BMS software. Color: white. Compatible Master Detectors: 353 650321, 353 651321, 353 651421, 353 652321, 353 652421, 353 750321, 353 751321, 353 751421, 353 752321, 353 752421, 353 852411
