CP Electronics MWS3A-PRM-2CH - Manual

Overview
The MWS3A-PRM-2CH Microwave presence detector
provides automatic control of lighting loads with optional
manual control. It 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 detector provides two independently controlled output
channels that can be used for a variety of applications.
 Occupancy of two independent lighting circuits using a
single detector, e.g. for essential and non-essential
supplies.
 Occupancy and lux control of one lighting circuit and just
occupancy control of a second circuit, e.g. where a row of
luminaries by a window is lux controlled whilst inner rows
are switched on occupancy only .
 Occupancy and lux control of a lighting circuit and just
occupancy control of a ventilation circuit .
 Occupancy on both lighting circuits, with separate lux
control on each circuit.
The unit 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.
