Product Guide
The MWS1A series of microwave presence detector
switches are designed to provide automatic control of
lighting, heating or ventilation loads. The MWS1A detects
movement using a highly sensitive microwave detector.
This works by emitting low power microwave signals and
measuring the reflections as the signals bounce of moving
objects. The MWS1A is optimised for wall mounting
applications to give detection over long distances.
When movement is detected the load is turned on. When
an area is no longer occupied the load will switch off after
an adjustable time out period.
The internal light sensor provides additional energy saving
in lighting applications. When an area is occupied lighting is
only switched on when the level of natural light is below a
preset level.
Three variants are available
MWS1A-PRM
Mains voltage, switched live contact
MWS1A-PRM-VFC
Mains voltage, isolated changeover
contact
MWS1A-PRM-LV
Low voltage, isolated changeover
contact
Microwave Sensor
Detects movement within the unit's detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an IR
(infrared) handset.
Light Level Sensor
An integral adjustable photocell allows the lights to be kept
off if there is sufficient ambient light.
Presence detection
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.
