Open-area smoke detection system

The open-area smoke imaging detection (OSID) system designed by Xtralis features an emitter that sends both IR- and UV-coded light signals to the imaging sensor, which enables the system to discriminate between real smoke and other objects, including steam and dust.

The open-area smoke imaging detection (OSID) system designed by Xtralis features an emitter that sends both IR- and UV-coded light signals to the imaging sensor, which enables the system to discriminate between real smoke and other objects, including steam and dust. The wide-angle imager compensates for vibrations and building movement, and can locate and lock in an emitter that is roughly aligned. Up to seven emitters can be used concurrently with a single imager, each placed at different heights to provide volumetric coverage. Absolute calibration provides detection up to 492 ft regardless of lighting conditions, smoke color, airflows, or other environmental conditions.
