Orbis Optical Smoke Detector

Product Overview

The Orbis Optical Smoke Detector works using 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 slow-burning, smouldering fires.
  • Performs well in black and white smoke.
  • Extra confirmation of smoke before alarm signal is given.
  • Reduced incidence of false alarms.
  • Sensing chamber keeps out dust and other airborne contaminants.
  • Operates over a broad range of voltages at extremes of temperature.
