Open-area Smoke Imaging Detection (OSID) by Xtralis is an innovative projected beam smoke detection system that combines dual-wavelength beams and optical imaging technology for early-warning smoke detection. OSID provides a cost-effective, reliable, and easy-to-install solution that overcomes common beam detection challenges such as false alarms and alignment difficulties.
How It Works:
Each emitter (up to seven per system) generates two coded light beams in the UV and IR frequencies. These beams carry a unique code recognized by the receiver, allowing it to ignore any UV or IR light from external sources, such as sunlight, which eliminates typical interference problems. Battery-powered emitters have a lifespan of up to 3 years.
In its simplest configuration, OSID consists of a single imager— a camera-like device with a wide field of view—paired with a wired or battery-powered emitter positioned across the protected area. The emitter sends coded infrared and ultraviolet signals to the imager. If the reception is disrupted by genuine smoke particles, the imager triggers an alarm. The dual-wavelength design allows OSID to discriminate between real smoke and non-threatening objects such as insects, dust, steam, or condensation, significantly reducing false alarms.
