Bộ cảm biến Helvar - 313 Low-Profile Microwave Detector

313 Low-Profile Microwave Detector


 313 Low-Profile Microwave Detector Datasheet



 The 313 Low-Profile Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.

The unit detects movement using its highly sensitive microwave detector. It emits low-power microwave signals, and measures 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. It can also be controlled using a Helvar infrared remote handset.

The unit can be mounted into a ceiling or wall void, or onto a solid surface using Helvar’s SBB-A or SBB-AB back boxes (available separately).

From hardware revision 4, the Low-Profile Microwave Detector can be used with a Helvar 401, 402 or 403 or a generic 12 V to 24 V power supply unit.



 Key Features
