The FS20X is a Multi-Spectrum (UV/IR/IR/VIS) Flame Detector by Honeywell, deploying a UV solar-blind sensor, maintaining fast response without false alarms over a broad temperature range. If the UV signal is impaired by smoke or lens dirt, the sensitivity will be reduced, but the unit will still alarm.

Detects hydrocarbon and non-hydrocarbon fuel fires in all environmental conditions. The operating temperature range is -40° to 85°C with two housing choices; Copper-Free Aluminum or 316 Stainless Steel housing. Kit versions include a HART module.

The detection range is over 60 m (200 feet) (very high sensitivity setting) for the detection of a 0.1m² (one square-foot) Heptane reference fire and has a cone of vision greater in volumetric coverage than most UV/IR detectors meaning fewer detectors are required.

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 must 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.
