FV421I IR Flame detector

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.

Key Features:

- Triple waveband infrared solar blind flame detection for optimum false alarm immunity

- Unrivalled black body rejection over a wide range of source temperatures

- Automatic Optical Integrity Monitoring

- 4 Range settings - 6m, 12.5m, 25m & 50m

- IS certified, Baseefa 14ATEX0245X, IECEx BAS 14.0113X

- Highly configurable via switch settings or P.C. software

- MED Marine approved

- SIL2 certified (Future Enhancement)

- Highly sensitive to flame thus increasing the probability of early detection of hydrocarbon fires over a longer range

- Able to see flames through smoke and through high densities of solvent vapours thus increasing the probability of early detection of hydrocarbon fires

- Insensitive to artificial light sources such as halogen lights

- Consistent high sensitivity flame detection throughout a 90° field of view

- Consistent detection of different types of hydrocarbon fuels from alcohol to aviation fuel

- Regular self-testing of critical electronic circuits and regular monitoring of the detector window (OIM) reducing the frequency of regular maintenance visits

- Options of different system interfaces as standard

- Sealed to IP66 and IP67 (when suitable cable gland and sealant are used) ensuring long term reliability in harsh environments
