The Honeywell Analytics Fire Sentry FS20X Flame Detector is a Dual IR/ UV/VIS Multi-Spectrum Flame Detector deploying a UV solar-blind sensor. The FS20X gives fast response without false alarms over a broad temperature spread and has a detection range over 60 meters (200 feet). Designed to be used in all types of industrial fires, suitable for hydrocarbon and non-hydrocarbon fuel fires.  If the UV signal is impaired by smoke or lens dirt, the sensitivity will be reduced, but the unit will still alarm.

FS20X Flame Detector is only available as a 90-degree field view. Operating temperature range is 40° to 85°C. Available in Copper-Free Aluminum or 316 Stainless Steel housing. Kit versions include a HART FSX-A014R module.

For communication, the operator can select between RS-485, Modbus Protocol and RS-485, FireBus II.  A software interface provides diagnostics, real-time graphs and downloading of FirePics and event logs.

An SM4 Stainless Steel Swivel mounting assembly has to be ordered with each Flame Detector.

  • Units include a real-time clock with data logging up to 200 events with historical time and date data
  • Optical path and electric self-testing
  • Visual indicators, green is power, red alarm, yellow fault
  • Sensitivity; very high (60m), high (45m), medium (30m) and low (15m) – switch selectable
  • Analogue output 0 – 20 mA stepped – source or sink user selectable
  • Optional HART-excludes EN54-10 units
  • Output Relays Alarm, Fault and Fire
  • Dual Microprocessors, one handles samples and signal, freeing the other for data, diagnostics and storage
  • FirePic Up to 6 pre-fire event data storage
  • Two ¾” NPT or 25mm conduit entries
  • Power 24 volt DC – low power consumption
  • Enclosure IP66
  • Approvals: FM, cFM, ATEX, IECEx, En54-10 and SIL 2 complaint

This series replaces SS4-A2, SS4-AS2 and SS2-AM models.
