Product Guide
The MWS6-PRM-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.
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.

The MWS6- PRM detects movement using a highly sensitive microwave detector.
  • Page 2: Sensor Functionality

    Detection diagram Area of high sensitivity Area of lower sensitivity Sensor functionality Detection Mode The Detection Mode can be set to behave in Presence or Absence mode:  Presence When movement is detected the load will automatically turn on. When the area is no longer occupied the load will automatically switch off after an adjustable time period.
  • Page 3: Installation

    Installation Choosing a Suitable Location The detector should be sited so that the occupants of the room fall inside the detection pattern shown opposite).  Avoid positioning the unit where direct sunlight may enter the sensor element.  Do not site the sensor within 1m of any lighting, forced air heating or ventilation. ...
  • Page 4 Installation The MWS6-PRM-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.
  • Page 5: Basic Programming

    Basic programming The functionality of the MWS6-PRM-LV is controlled by a number of parameters which can be changed or programmed by any of the following devices:  UHS5 Infrared Handset. See below for programmable functions.  UNLCDHS Infrared Handset (with LCD). See user guide for full programming details.
