  • Flashing LED option
  • Five response modes for adaptability to changing environments
  • Drift compensation to ensure constant sensitivity
  • Capable of recording site specific data in the detector
  • Alarm flags for fast alarm reporting
  • Conventional alarm facility during control panel processor fault
  • 360° visibility alarm indication
  • Responds well to fast-burning, flaming fires
  • Designed to operate in a variety of environments
