FireClass 516.300.421 FV421I IR Flame Detector

The FV421I Intrinsically Safe IR Flame Detectors are intended for applications demanding a high level of protection where a rapid response to fire is important within Exia zoned areas.

The FV400 series uses Triple IR Solar Blind technology for flame detection. This provides a reliable and cost-effective solution in standard flame detection applications especially where there is a single hazard in the field of view. The FV400 detectors use Triple IR Solar Blind sensing technology and flame detection algorithms to provide high performance sensing capabilities for hydrocarbon fires. This includes the ability to reliably sense flames through high densities of solvent vapours and black smoke, increasing the probability of early detection with consistent high sensitivity to flame throughout the whole field of view.

They also ensure consistent detection of many different types of hydrocarbon fuels from alcohol to aviation fuel. Multiple interfaces are provided with the option of an integral CCTV camera to provide a visual means of operator verification.
