Ceiling Mounted Microwave Presence Detector
This series of microwave presence detector switches are designed to provide automatic control of lighting, heating or ventilation loads. The switch 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 microwave presence detector is optimised for ceiling 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.
The /IP variant of these products is sealed to IP66
