Product Guide
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.

    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 MWS3A-PRM-LV is designed to be mounted using either:  Flush fixing, or  Surface fixing, using the optional Surface Mounting Box (part no. MWS3A-DBB). Both methods are illustrated below. Warning - be careful bending springs when mounting unit. Flush fixing Hole Ø74mm Attach cable clamp...
  • Page 5 Readback function (UNLCDHS handset only) The UNLCDHS has the ability to read back the settings stored in a device. To read back individual parameters  Navigate to the parameter and press the ‘R’ (Read) button whilst pointing at the device. The handset will click when the parameter has been read back, the device will flash its LED, and the value will be shown against the parameter in the menu.
  • Page 6: Basic Programming

    Basic programming The functionality of the MWS3A-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. For most basic programming operations the UHS5 handset can be used and the following procedures are based on using this device.
