Front features

The MWS3A-PRM-LV Microwave presence detector
provides automatic control of low voltage loads including
lighting and BMS systems with optional manual control. The
MWS3A-PRM 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.
Functioning as a presence detector, the unit can turn lights
on when a room is occupied and off when the room is
empty. Optional settings allow lights to be turned off in
response to ambient daylight.
The MWS3A-PRM has a unique adjustable sensor head
that allows the area of detection to be optimised for the
application.
All functionality is fully programmable using an IR handset.
