Do you trust new thermal imaging technology to improve fire safety in local industrial facilities?
Teledyne Flir has secured UL 2684 certification for its A40, A50, and A70 thermal imaging cameras. These are the first models to achieve this listing, allowing their integration into official fire detection systems.
Why it matters
This classification enables thermal imaging to serve as a primary component in fire safety, providing faster detection of potential fires than traditional smoke or heat sensors by identifying heat signatures early.
The UL 2684 classification formally integrates thermal imaging into fire detection systems compliant with NFPA 72 standards. These units enable continuous monitoring for thermal anomalies across interior areas and specific assets.
The players
Teledyne Flir
Teledyne Flir is a company that specializes in the design and production of thermal imaging cameras and sensor-based solutions for industrial, commercial, and government applications.
National Fire Protection Association
The National Fire Protection Association is a global self-funded nonprofit organization devoted to eliminating death, injury, property, and economic loss due to fire, electrical, and related hazards.
The details
The Teledyne Flir Axx-Series cameras detect hazardous thermal conditions before visible smoke or flames appear, triggering alarms through compatible control systems. This capability allows a single camera to provide automated, code-compliant fire monitoring for large facilities.
Timeline
The Flir Axx-Series cameras achieved UL 2684 classification in October 2026.
Seasonal Patterns
The certification extends the application of NFPA 72 by validating new technology for code-compliant fire monitoring. This development marks a formal expansion of NFPA 72 by incorporating advanced thermal sensor data into established fire alarm protocols.
Facility managers and safety officers can now incorporate these cameras into certified fire detection arrays to enhance early warning capabilities. This integration allows for more precise, asset-specific monitoring that traditional sensors may miss.
The takeaway
Thermal imaging represents a shift toward predictive fire safety that catches hazards before combustion begins. Professionals should assess whether their current alarm infrastructure can be upgraded with these certified sensors to improve response times.
