Microwave Movement Sensor – Ceiling Dimming

The MWS6-DD microwave presence detector provides automatic control of lighting loads with optional manual control. It can be used on incandescent, fluorescent and compact fluorescent lighting and DSI or DALI digital dimming ballasts over 1 or 2 channels. The MWS6-DD detects movement using a highly sensitive microwave detector. This works by emitting low power microwave signals and measuring the reflections as the signals bounce off moving objects. When an area is no longer occupied the load will switch off after an adjustable time out period.

The dimming channel of the detector can be used to control the light output of light fittings that are fitted with dimming ballasts. The detector measures the overall light level in the detection area and calculates the correct output for the light fittings, to achieve a preset lux level (maintained illuminance).

The switching channel of the detector can either be used to isolate the supply to the dimming ballasts (saving on the standby current of the ballasts) or to switch a separate channel of standard, non-dimming lights.

Two input terminals can be used to manually override the dimming levels and override the lights on or off.
