HELVAR digidim 314 Installation Manual

Helvar 314 Tilting Microwave Detector
Installation Guide
The 314 Tilting Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.
The unit can also be controlled using the Helvar 303 IR (infrared) remote control handset.
The 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 314 has an adjustable sensor head that allows the area of detection to be optimised for each particular purpose.
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.
