The Orbis Marine Multisensor Detector benefits from the same false alarm reduction technology as the optical detector, with the addition of a heat sensing element.

Product code: ORB-OH-43001-MAR



Main features and benefits:

  • Responds well to fast burning, flaming fires
  • Reduced false alarms
  • Increased reliability of detection
  • Sensing chamber keeps out dust and other airborne contaminants
  • Operates over a broad range of voltages at extremes of temperature
  • Flashing LED option
