IR3-HD
Triple IR Flame Detector with HD Camera
The FlameSpec™ IR3-HD flame detector provides exceptional detection performance of all types of hydrocarbon fires (visible and non-visible).
The detector responds to slow-growing fires as well as fast fire eruptions using improved triple IR (IR3) technology operating in all weather and light conditions with highest immunity to false alarms.
The detector also provides a high-definition (HD) color video output of the monitored area with clear imaging of fire events and personnel at distances up to 100 ft (30 m), allowing responders to know the exact situation before entering the hazardous area. Video and data of events are saved quickly to non-volatile memory for post-incident investigation. The recordings start one minute before detection and continue for up to four minutes.

When Milliseconds Matter:
High-Speed Detection for NFPA 33 Compliance
From lithium battery lines to electrostatic spray booths, speed is the ultimate safety metric. NFPA 33 (Section 9.9.1) requires a detection reaction time of 0.5 seconds or less—a benchmark that many standard detectors fail to meet.
The FlameSpec™ X5 range is purpose-built for these high-speed applications. With FM-verified performance, the X5 series provides the rapid response necessary to trigger automatic shutdowns, protecting both your personnel and your high-value production assets..
Application Challenges
High-risk areas require a high speed of response to small explosive or fast-growing fires.
High-speed fire detection without false alarm is critical to maintain safety and operational efficiency.
Detection within the spray booth should activate system shutdown and shut off ventilation within 0.5seconds for NFPA 72 and NFPA 33 compliance.
The FlameSpec ™ X5 hispeed detector has been designed and independently tested by FM to confirm detection speeds down to 0.3 seconds for IPA and other alcohols used in painting and coating applications.
Detection Strategy & Zone Types
IR3 Flame Detection with high-speed algorithm
Different areas of automotive facilities require tailored detection strategies:
Automotive Spray Booths:
High speed of response, sub 0.5 seconds.
Lithium Battery Production:
High speed of response to lithium-ion batteries and plastic fires.
Hydrogen Fuelled Vehicles:
Use of Hydrogen changes the risk and must be indendantly assessed. Hydrogen burns with an invisible flame and can be an explosive risk.
