LED weather-proof luminaire with IP66 protection for use in applications with high demands on variability, efficiency, quality of light and technology. The luminaire is part of an assortment with constructionally identical, mounting-compatible variants. These versions are available with alternative optical systems, light engines with settable luminous flux levels and with a connection option to light management systems and emergency lighting systems. LiveLink SwarmSens master luminaire (DMM) with integrated HF sensor for motion detection in combination with a brightness sensor for daylight detection and Bluetooth module for networking up to 4096 LiveLink SwarmSens master luminaires and slave (DMM) luminaires in a mesh network. Bluetooth® signal range up to 15 m. Integrated HF sensor in the 24 GHz frequency range for detecting movements at speeds between 1 and 25 km/h, adjustable in 10 steps from 30 seconds to 60 minutes. The detection range at an installation height of 5 m is approx. Ø 10 m. Group assignment of luminaires is performed via DIP switch (64 groups) or smartphone app (255 groups). Configuration of a swarm function of the existing luminaire groups for pre-running light via the app. Suitable for use in HACCP, IFS and/or BRC Global Standard Food certified companies.
