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.

* Responds well to slow-burning, smouldering fires
* FasTest® 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
