The Kidde ORION XT HSSD detects particles of combustion at levels of obscuration as low as 0.0015% per foot; thousand of times more sensitive than conventional smoke detectors. Laser optics, and Kidde's particle counting technology provide for a stable, highly reliable incipient fire detector. An engineered & balanced air sampling network insures equal sensitivity throughout protected areas. The ORION XT is widely used for critical, high-asset equipment protection; process controls, robotics, MIS facilities, and automated conveyances.
