DS939 Series Panoramic Detectors

  • Up to 7.6 m (25 ft) mounting height
  • Fully adjustable optics for coverage integrity and customization
  • Hinged chassis and base plate for easy installation
  • High efficiency LED and light pipe system for easy walk testing
  • First Step Processing (FSP)
  • 360° x 21 m (70 ft) diameter pattern

The ceiling mount DS939 PIR Detectors provide a 21 m (70 ft) panoramic coverage pattern and can be mounted on ceilings as high as 7.6 m (25 ft). With three separate PIR sections that are fully adjustable, the DS939 detectors provide coverage integrity at all mounting heights, plus the ability to customize the coverage for specific areas. The DS939 detectors use several patented processing techniques to provide excellent catch performance with freedom from false alarms.
