Fits industrial fire and flame detection where you need a Honeywell FS20X—multi-spectrum UV / Dual IR / VIS sensing with a 90° horizontal cone of vision and switch-selectable ranges to about 60 m on a 0.1 m² n-heptane fire.
Key advantages
- Spectral — UV 185–260 nm; VIS 400–700 nm; Near IR 0.7–1.1 µm; WideBand IR 1.1–3.5 µm
- FOV — 90° horizontal cone (±45° on-axis)
- Range — Very high ~60 m / high 45 / medium 30 / low 15 m (switch selectable)
- Response — About 3–5 s to 0.1 m² n-heptane at 30 m
- Power — 24 Vdc nominal (18–32 Vdc)
Typical applications
- Petrochemical fire detection.
- Turbine / generator enclosures.
- Hangar and fuel-handling areas.
Selection guide
- Sensitivity setting
- Output / protocol options
- Mounting / weather shield
Common mistakes
- Obstructed FOV.
- Wrong sensitivity for nuisance sources.
- Supply outside 18–32 Vdc.
