FAP-420/FAH-420 Automatic Fire Detectors LSN improved version

FAP-420/FAH-420 Automatic Fire Detectors LSN improved version

  • Combination of optical, thermal and chemical sensors with intelligent evaluation electronics.
  • Earliest detection of lightest smoke (TF1 & TF9) with the double-optical smoke detectors featuring Dual-Ray technology
  • Detector properties adapted to cater for room usage
  • Drift compensation in optical and gas measurement section
  • Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators

The 420 Series Automatic Fire Detectors offer a superb accuracy as well as detection speed and precision. The versions with dual-optical sensor (DO-detectors: FAP-DO420, FAP-DOT420, FAP-DOTC420) are able to detect lightest smoke (TF1 and TF9). These detectors provide all advantages of LSN improved version. The addressing of the detectors can be configured with the integrated turning switches.
