The Aurora Microwave motion sensor is a fantastic accessory for our Ostia SQR range of highbays, offering 3/4" entry to the end of the highbay. The Aurora Sensor allows for 4 step dimming levels from 10% to 50% and 8 hold times from 0 seconds to continuous, until the lights are switched off or presence is detected. The Aurora Sensor is a fantastic solution where areas of the warehousing are used for short periods of the day which enables extra power savings. The Sensor also features a daylight sensor so once presence is not detected and the light levels are at a brightness the units will not switch on as there is enough light present. The unit can be programmed with the Aurora Remote controller or via the dip switches within the unit. As standard our sensors are set at 5 minutes without detection dim to 50% and hold time is set to stay on at this level until motion is detected or lights are switched off manually at the end of the working day.
