Xtralis Open-area Smoke Imaging Detection (OSID)

Large open spaces - airports, train stations, stadiums, shopping malls, warehouse and large atriums - pose unique challenges to reliable fire detection due to their environmental nature and odd or cavernous shapes. Xtralis has introduced Open-area Smoke Imaging Detection (OSID) for smoke detection for open spaces. OSID can overcome the limitations of traditional (beam) detection solutions when used in large, open spaces where standard sensitivity detection is required.

The detector features dual light frequencies that minimise nuisance alarms - using dual light frequencies (UV and IR) assists in discriminating between real smoke and objects including insects, birds, steam, condensation and dust, thereby reducing nuisance alarms.

The wide viewing angle feature allows for easy alignment and high tolerance to building movement and vibration. OSID uses a CMOS imaging chip with many pixels rather than a single photodiode, providing the OSID detector with a wide viewing angle to locate and track emitters (transmitters). With good tolerance to building movement and vibration, fault or false alarms are not generated.

Alignment is simple, which results in fast installation and set-up. Exact alignment between the emitter (transmitter) and imager (receiver) is not required, reducing the cost of installation and maintenance.
