OSID smoke detector

Rate it

OSID by Xtralis provides reliable, cost-effective smoke detection for open spaces where fire detection presents unique challenges and where very early warning is not always the priority.

In its simplest configuration, OSID by Xtralis uses one imager, a camera-like device with a wide field of view, and a wired or battery-powered emitter roughly aligned on the opposite wall within the protected area. The emitter sends both infrared and ultraviolet coded light signals to the imager. If the light reception is altered due to the presence of genuine smoke particles, the imager will go into alarm. The novel use of dual light frequencies in an open-path device enables OSID to discriminate between real smoke and other objects, including insects, steam, condensation and dust, thus drastically reducing false alarms.


OSID vs. Beam, Heat and Flame Detectors 
Beam, heat and flame detectors are commonly used in open spaces for fire detection but have proved problematic. Beam detectors are susceptible to building movement and prone to false alarms due to dust, condensation and object intrusion. They also are difficult to align and therefore time consuming to install. While offering higher reliability, heat and flame detectors only detect fire in the developed, flaming stage, which negates early detection and results in threats to life safety and major property damage. OSID overcomes all of the shortcomings inherent to these systems.

 

3-D Volumetric Coverage 

A significant benefit of OSID is its ability to provide volumetric coverage. As many as seven emitters can be placed within the field of view of a single imager, each placed at different heights. The OSID imager's large viewing angles, both horizontal and vertical, enable three-dimensional area coverage for design flexibility and additional deployment savings. Unlike other volumetric technologies, OSID delivers absolute calibration for consistent detection performance regardless of lighting conditions, smoke color, airflows or other environmental conditions.
