Teledyne FLIR has confirmed that its A40, A50, and A70 thermal imaging cameras are the first models to achieve UL 2684 listing as thermal image fire detectors. The certification, announced September 22, 2026, has drawn renewed attention this week as the company published guidance on how the listing applies to European fire protection projects.
UL 2684 — formally ANSI/CAN/UL 2684 — is a joint US-Canadian standard specifically written for video and thermal image detectors used in fire alarm systems. The listing allows the cameras to be integrated into NFPA 72-compliant fire detection and alarm systems, something previously unavailable for any thermal camera. Conventional smoke or heat detectors respond after combustion begins; the Axx-Series cameras detect abnormal heat signatures before that point and can trigger alarm events through compatible control systems when predefined conditions are met.
Target applications identified by Teledyne FLIR include data centers, warehouses, distribution centers, manufacturing facilities, and utility infrastructure. The cameras process analytics on-device, which reduces dependence on external servers. Teledyne FLIR describes the technology as complementary to conventional fire detection, not a replacement for it.
Facilities managers and fire protection engineers evaluating early detection for high-value or high-risk spaces may want to confirm whether their jurisdiction's AHJ (authority having jurisdiction) will accept UL 2684-listed thermal cameras as part of an NFPA 72 system design. The listing does not replace code compliance reviews, but it does provide an independently verified performance benchmark that specifiers can reference in project submissions.
