The Tilting Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.
The unit can also be controlled using a Helvar infrared remote handset, such as the 303 DIGIDIM Infrared Remote Control.
Helvar’s 314 detects movement using its highly sensitive microwave detector. It works by emitting low-power microwave signals
and measuring the reflections as the signals bounce off moving objects.
The unit has an adjustable sensor head that allows the area of detection to be optimised for the required application.
When an area is no longer occupied, the load switches off after a certain time. This time-out period is configured using Helvar’s
lighting system design and control software: Designer, or Toolbox.
