OSID Open-area Smoke Imaging Detector - OSI-90 Imager 80° FOV

The company that revolutionized very early warning smoke detection with VESDA has reinvented smoke detection for open spaces with Open-area Smoke Imaging Detection (OSID). 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.

Key Features:

OSID’s uncompromising performance is based on the patented use of digital imaging, dual-frequency beams and smart algorithms delivering:

  • Patented dual wavelength, UV & IR, particle detection
  • CMOS Imager with wide viewing angles
  • Simple installation, commissioning and maintenance
  • High tolerance to vibration and structural movement
  • High tolerance to dust, fogging, steam, reflections and object intrusion
  • High resistance to reflected sunlight
  • On-board log memory
  • Software tool for diagnostic purposes
  • Aesthetically discreet and 3D coverage
  • Long range up to 150 m. (492 ft.) with minimal free space (Ø15 cm./5.85”)

Applications:

OSID is ideal for use in a wide range of industries and applications. These include atriums, domes and large rooms in:

  • Airports
  • Train stations
  • Shopping centres
  • Stadiums
  • Educational facilities
  • Hotels, convention centres and office buildings/complexes
  • Entertainment venues
  • Warehouses and production floors

The OSI-90 Imager is used in multi emitter applications, or in shorter distance applications.  The appropriate number of OSE-SP-01, OSE-SPW or OSE-HPW Emitters must be paired with the Imager to a maximum of seven.
