HELVAR digidim 313 Installation Manual

313 Low-Profile Microwave Detector
The 313 Low-Profile Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.
The unit can also be controlled using the 303 IR (infrared) remote control handset.
The 313 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.
When an area is no longer occupied, the load will switch off after a certain time. This time-out period is configured using
Helvar's lighting system design and control software: Designer, or Toolbox.
