Honeywell FS24X Plus — IR3 flame detector (hydrocarbon and hydrogen fires)
The Honeywell FS24X Plus is an advanced flame detector with a triple-infrared (IR3) sensor, providing fast, reliable detection of hydrocarbon and hydrogen fires — even in tough conditions (rain, limited visibility). Maintenance-free and requiring no calibration, with a highly visible LED Halo ring that signals device status from a distance and a rich set of outputs (4–20 mA, relays, HART, Modbus), it integrates easily with fire-safety systems. EN54-10, FM3260 and SIL2 certification confirms high reliability.

Key features
- Triple-infrared (IR3) sensor — hydrocarbon and hydrogen fires.
- Operation in difficult conditions (rain, limited visibility).
- Halo LED ring: green (OK), yellow (fault/warning), red (alarm) — visible from a distance.
- Outputs: 4–20 mA, relays (Fault/Suspected/Confirmed), HART, Modbus, RS-485.
- Maintenance-free, no calibration; self-diagnostics and warnings.
- SM4 bracket as standard (marine version SM4-M); field-replaceable optoelectronics module.
- Flame Manager software (PC) + FirePic event analysis; configuration via HART/Bluetooth.

Frequently asked questions (FAQ)
What fires does the Honeywell FS24X Plus detect?
Hydrocarbon and hydrogen fires, thanks to the triple-infrared (IR3) sensor — even in difficult conditions, e.g. limited visibility or rain.
How does the FS24X Plus integrate with a system?
It offers many outputs: 4–20 mA, relays (Fault/Suspected/Confirmed Alarm), HART, Modbus and RS-485, which makes integration with fire safety systems easier.
Does the FS24X Plus require calibration?
No. It is maintenance-free and requires no calibration; it performs self-diagnostics and signals its status with the Halo LED ring. It holds EN54-10, FM3260 and SIL2 certification.
