The MWS3A -PRM -VFC Microwave presence detector
provides automatic control of lighting loads 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 re ections as
the signals bounce o moving objects.
The output channel comprises a mains voltage relay
capable of simple on/o switching. This unit provides an
isolated voltage free contact output.
Functioning as a presence detector, the unit can turn lights
on when a room is occupied and o when the room is
empty. Optional settings allow lights to be turned o 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.
Two variants are available.
MWS3A -PRM -VFC
MWS3A -PRM -VFC -NC
