Orbis Marine Optical Smoke Detector

ORB-OP-42001-MAR

The Orbis Marine Optical Smoke Detector operates on the well-established light scatter principle. However, the sensing technology is radically different in design from previous optical detectors and significantly reduces false alarms.

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
