Open-area Smoke Imaging Detection (OSID) delivers advanced projected beam smoke detection through dual-wavelength projected beams and optical imaging technology. OSID provides early-warning smoke detection in a cost-effective, reliable, and easy-to-install solution, addressing common beam detector challenges such as false alarms and alignment difficulties.
Key Features:
Maximum detection range of 150 m (492 ft) for the OSI-10; 200 m (656 ft) for CPR-approved products
Dual-wavelength LED smoke detection
Optical imaging with CMOS imaging chip
On-board event log for fault and alarm diagnostics
High tolerance to false alarms caused by building movement
Resistant to transient dust, steam, and intrusion of solid objects
Easy alignment with wide adjustment and viewing angles
No precise alignment required; tolerant of alignment drift
Automatic commissioning in under 10 minutes
Simple DIP switch configuration
Minimal maintenance requirements
Three selectable alarm thresholds
Status LEDs for Fire, Trouble, and Power
Conventional alarm interface for straightforward fire system integration
3-D Volumetric Coverage
3-D Volumetric Coverage
OSID enables true volumetric protection by allowing up to seven emitters within the field of view of a single imager, each at different heights. Its wide horizontal and vertical viewing angles provide three-dimensional area coverage, offering design flexibility and cost savings. Unlike other volumetric technologies, OSID delivers absolute calibration for consistent detection performance regardless of lighting conditions, smoke colour, airflow, or other environmental factors.
Applications
OSID is ideal for large, open spaces where reliable, easy smoke detection is essential, even when high-sensitivity detection is not required. Common applications include:
Airports
Train stations
Shopping centres
Stadiums
Hotels, convention centres, and office complexes
Entertainment venues
Warehouses and production floors
