Overview
The MWS3A-PRM 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 reflections as
the signals bounce off moving objects.
The output channel comprises a mains voltage relay
capable of simple on/off switching.
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.
