Multi-spectrum IR5 flame detection with long-range performance
Omniguard® model 760 Multi-spectrum Infrared Flame Detector
The Omniguard model 760 multi-spectrum infrared flame detector senses five discrete infrared wavelengths for early fire detection. It uses the patented Fire Event Analysis algorithm for strong false-alarm immunity and is suited for refineries, pipelines, production platforms, power plants, compressor stations, LNG/LPG facilities, tank farms, hangars, and petrochemical plants.
- Patented Fire Event Analysis algorithm
- Five discrete infrared wavelengths
- 90-degree field of view
- Long-distance sensitivity modes
- Automatic through-the-lens self-test
