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

Product code: ORB-OP-12001-APO



Main features and benefits:

  • Responds well to slow-burning, smouldering fires
  • ® takes just four seconds to test and confirm detectors are functioning correctly
  • Transient rejection algorithms reduce false alarms
  • Automatic drift compensation with DirtAlert®, a yellow flashing LED, to easily identify dirty detectors
