Open-Area Smoke Image Detection (OSID)

Open-area Smoke Imaging Detection (OSID) is an innovative system for reliable, cost-effective smoke detection for large, open spaces requiring standard sensitivity detection. In its simplest configuration, OSID 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.


  • Maximum detection range of 150 m (492 ft) for the OSI-10
  • Status LEDs for Fire, Trouble and Power
  • High false-alarm immunity
  • Dust and intrusive solid-object rejection
  • Easy alignment with large adjustment and viewing angles
  • No need for precise alignment
  • Tolerant of alignment drift
  • Automatic commissioning in under 10 minutes
  • Simple DIP switch configuration
  • Dual wavelength LED-based smoke detection
  • Simple and easy maintenance
  • Conventional alarm interface for straightforward fire system integration
  • Three selectable alarm thresholds
  • CE-EMC, CPD (EN54-12), VdS and UL/ULC approved
  • Other major agency approvals pending


Large, open spaces where high-sensitivity detection is not the priority but reliable, easy detection is essential, including:

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