FAD-420-HS-EN Duct detector housing with base

FAD-420-HS-EN Duct detector housing with base

  • Use in ventilation systems with air velocities from 1.5 m/s to 20 m/s
  • For the activation of fans, door controls or external display devices an optional Relay Board can be installed
  • A clear section on the frosted cover allows observing the alarm LED of the integrated FAD-425-O-R Detector
  • Control to prevent unwanted removal of the cover
  • Easy installation of the FAD-425-O-R Detector
  • Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators

The FAD-420-HS-EN Duct Smoke Detector with integrated FAD-425-O-R Detector detects smoke in ventilation ducts. Smoke particles in the air are reliably detected and reported to the fire panel by the LSN improved bus system.
