Ceiling motion sensor

SIRIUS is a PIR (Passive InfraRed) ceiling motion sensor, with built-in light sensor and ‘STAR LIGHT’ LED. This high sensitive motion sensor is used to control light circuits when a minimum light level is sensed. It  also can control dimmed light circuits and keep them at a predefined light level, based on the reflected light level which is measurement by the internal light sensor.
SIRIUS is not only a light control device, but integrated with the TDS system, it becomes an important part of comfort-, safety- and energy management.
SIRIUS is your energy manager who always keeps track of the comfort and safety of people in motion. Be it standing or sitting down..
The built-in ‘STAR LIGHT’ LED works as a motion indicator and as a discrete night light if no area lights are active or when they are defect.

High accuracy motion sensor with 192 detection zones; LED = 10 Lumen 3000°K.
