Product Guide
The MWS6-PRM-VFC-LV Microwave presence detector
provides automatic control of low voltage loads including
lighting and BMS systems with optional manual control.
The MWS6-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.
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 off when the room is
empty. Optional settings allow lights to be turned off in
response to ambient daylight.
All functionality is fully programmable using an IR handset.
Two variants are available.
MWS6-PRM-VFC-LV
MWS6-PRM-VFC-LV-NC
Microwave Sensor
Detects movement within the unit's detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an
IR (infrared) handset.
Light Level Sensor
Measures the overall light level in the detection area
Status LEDs
The LED flashes Red to indicate the following:
Walk Test LED active
Valid setting received
Output Connector
Connection to a switched load.
Power Input & Switch Input Connector
Used to connect power to the unit and two input terminals
that can be used to manually override the lights on or off.

     Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level parameters. Normally closed option The MWS6-PRM-VFC-LV-NC provides a normally closed contact for fail safe operation. If the unit fails, the outputs will default to on.
  • Page 3: Installation

     Avoid metallic objects directly in front of the sensor head. MWS6-PRM-VFC-LV connections Min 11.5VDC max 36VDC Min 10VAC max 26.5VAC MWS6-PRM-VFC-LV-NC (for fail safe operation) Min 11.5VDC max 36VDC Min 10VAC max 26.5VAC Absence detection  To use absence detection a retractive (momentary) switch must be connected between the 2 terminals on the diagram.
  • Page 4 Installation The MWS6-PRM-VFC-LV is designed to be mounted using either:  Flush fixing, or  Surface fixing, using the optional Surface Mounting Box (part no. DBB). Both methods are illustrated below. Flush Fixing Hole Ø64mm Warning - be careful bending springs when mounting unit.
