Wire the products as in the diagram opposite, simply by connecting to the relevant port of the Rapid
LCM using a Cat5 patch cord. An additional RJ45 connector is provided to daisy chain sensors to-
gether.
The detector should be sited so that the occupants of the room fall inside the detection pattern
shown overleaf, at a recommended ceiling height of 2.8m.
Corridors or aisles:
the unit should be placed at the end of the corridor or aisle and the sensor
head should be angled to look down the corridor or aisle.
Open plan areas and offices:
the unit can be mounted in a corner looking outwards in which case
the sensor head should be angled . Or the unit can be mounted in the centre of the area with the
sensor head flat.
Note that the higher the sensor is installed the shorter the detection range will be.
Mount using one of the two options overleaf (for surface fixing order the MWS3A-DBB as a
separate item).
Do not site within 1m of any lighting or ventilation equipment.
Do not fix to a vibrating surface.
Site as far away as possible from the surface of metal objects.
The EBR-MWS3A presence detectors are designed to provide automatic control of lighting via the
RAPID lighting control system. They detect 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 EBR-MWS3A has a unique adjustable sensor head that allows the
area of detection to be optimised for the application. When an area is occupied the Rapid system can
be programmed to turn the lights on. When an area is no longer occupied the load will switch off after
an adjustable time out period. An adjustable internal light sensor provides light level information to the
RAPID system to allow lights to be kept off if sufficient daylight is present, and to enable maintained
illuminance for dimming systems.
An integral IR sensor in the unit allows the unit to be commissioned, and used in conjunction with a
remote control handset (part no: UHS) to:
Act as a conventional dimmer
Override the unit on or off
Change the maintained illuminance lux setting
