Used to set the states of the
switched live output and low
voltage relays in three different
states (‗Permanently ON‘,
‗Automatic ON/OFF‘ (controlled by
sensor detection) and
‗Permanently OFF‘).
It is advised
that if a relay channel is not
being used it is set to OFF.

The MWS7 is a microwave occupancy detector that provides automatic control of lighting loads, and is
especially suited for warehouse applications. When a person or fork lift truck enters the aisle or corridor,
the sensor will turn the lights on, or raise the level of light output. After a pre-determined period, the lights
will turn off or dim down. The detector uses advanced microwave technology that allows the range of
detection to be accurately set, irrespective of whether the object is a person or a fork lift truck (a common
problem with other types of detector is that larger objects are picked up at longer distances, making
accurate setup impossible). A further benefit of the MWS7 is that it has good immunity to vibration.
Three output channels are provided:
Switching channel with a high power relay
Switching channel with a low voltage, low power isolated contact
Dimming channel capable of controlling up to 20 DSI or DALI ballasts
The detector has a built in photocell that measures the overall light level in the detection area. This can be
used to turn the lights on and off when natural light is sufficient, or on dimming systems to calculate the
correct output for the luminaires to achieve a preset lux level (maintained illuminance). The dimming
channel can also be used to set the luminaires to a ―standby‖ dim level rather than switching off
completely.
Input terminals are provided to give the following features:
Manual override of the dimming levels and switched outputs
Slave detector input
—
for use in dimming systems
External lux input
—
disables the output when there is sufficient natural light
Manual adjustments can be made to the sensitivity, range, lux and time settings using the physical
controls inside the sensor. Alternatively, an integral infra-red sensor in the unit allows the unit to be
programmed using the optional DD-LCDHS-LR programming handset, working to a range of 15m. This
gives complete flexibility over many of the operating parameters.
