BMS

For use in compatible lighting control systems

B.E.G. now offers a large number of the “occupancy detectors” as BMS multi-sensors. The advantage of BMS multi-sensors over the classic connection of 24 V multi-sensors is that the 2-wire DALI cable that is often already available or planned for lighting can be used for the connection. The simplification is enormous: whereas a con-ventional 24 V multi-sensor often required an individual terminal per sensor and an individual
supply line, a large number of BMS sensors can be connected to one line, depending on the DALI voltage supply. DALI luminaires and multi-sensors simply share the BUS line.

ensor information such as movement, presence and light values are transmitted by the BMS multi-sensors even without cyclical polling in “multi-master” mode. This sensor information is standardised. This means that the B.E.G. BMS multi-sensors can be used with all multi-mastercapable application controllers that support multi-sensors according to IEC 62386 parts 101, 103, 303 and 304.With state-of-the-art digital passive infrared sensors, the detectors offer unique detection quality for motion and presence. B.E.G.‘s light measurement is also particularly reliable thanks to external light sensors and allows constant light regulation up to 16 m mounting height with the PD4-BMS-GH, for example. The BMS family offers detectors for almost all areas of application, for example the “PICO” mini-sensor with an installation depth of only 11 mm, the super-flat PD11 sensor or the PD4-BMS-GH high-bay detector.
