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
