The Orbis optical smoke detector operates on the well-established principle of light scattering. The detection technology used is radically different from previous optical detectors and significantly reduces false alarms.

• Reacts well to slow-burning and smoldering fires.
• FastTest® only takes four seconds to test and

  confirm that the detectors are functioning correctly.

• The transient rejection algorithms reduce false alarms.
• Automatic drift compensation with DirtAlert®, a flashing yellow LED, to easily identify dirty detectors.
