Do you trust new digital thermal monitoring systems as much as traditional fire alarm technologies?
Teledyne FLIR has secured the UL 2684 listing for its A40 and A70 thermal imaging cameras. This certification verifies that the models meet the joint U.S. and Canadian standard for thermal image detectors used in fire alarm systems.
Why it matters
The listing provides an objective framework for evaluating thermal image fire detection technologies against independent standards. This compliance ensures the devices meet requirements for fire testing, electrical performance, and durability as mandated for fire detection purposes.
The UL 2684 standard establishes rigorous requirements for fire testing and electrical performance in detectors. These devices must comply with the 2025 edition of NFPA 72, which mandates specific listing requirements for thermal fire detection systems.
The players
Teledyne FLIR
This company is a global manufacturer of thermal imaging infrared cameras and sensors.
UL Solutions
This global safety science company develops the UL standards used for testing and certifying products.
The details
The Axx-Series cameras utilize thermal detection to monitor temperature thresholds and rates of increase across every pixel in a scene. Once hazard conditions are identified, these cameras can trigger events through integrated, compatible fire alarm control systems.
Timeline
The 2025 NFPA 72 edition introduced requirements for thermal fire detection.
The UL 2684 listing achievement was announced on October 1, 2026.
Seasonal Patterns
This certification reflects a transition toward standardized thermal detection as outlined in the 2025 edition of NFPA 72. It aligns commercial hardware with updated regulatory expectations for fire safety infrastructure.
Facility managers and engineers should verify that their systems utilize listed equipment to meet updated 2025 NFPA 72 requirements. Consult with local Civil Defence and project-specific authorities to ensure that this certification fulfills all site-specific compliance mandates.
The takeaway
Achieving this industry-standard listing marks a significant shift for thermal imaging from supplemental monitoring to primary fire detection. Designers must now prioritize listed hardware to ensure code compliance in new fire safety installations.
