This is a mid-range Microwave Presence/Absence Detector, for the automatic control of lighting, heating and ventilation. This detector has a low profile design which allows flush mounting into a ceiling tile, or surface mounting using a detector back box. Its reduced head size makes it unobtrusive to occupants. The MWS6 detects movement using a highly sensitive microwave detector. The simple plug in connections reduce installation time. The optional infrared remote handset allows the user to override the set up.
