The Next Generation in Reliable Flame Detection
- Reliable flame detection: Rapid detection of a wide range of hydrocarbon and hydrogen fires with advanced diagnostics including window clarity and performance.
- Maintains coverage while operating in challenging environments: The use of solid state, wide band sensors means that operation can continue in poor visibility.
- At-a-glance instrument status: FSX24 Plus has a high visibility LED Halo ring that can be seen from a distance to show instrument status.
- Simplified installation using lightweight graduated mount: FS24X Plus includes the SM4 mount as standard, which enables easy mechanical installation. A marine version mount (SM4-M) is also available.
- Simplified Maintenance: FS24X Plus is supported by a PC App (Flame Manager) and HART® for set-up. Flame Manager includes post event analysis with Honeywell’s powerful FirePic™ tool. The internal opto-electronics module can be quickly swapped in the field if needed.
- Global hazardous area and performance approvals: ATEX, IECEx; cFMus; INMETRO, CCC*, SIL2, FM3260, EN54-10
- Marine Certification*: ABS, Lloyds, BV, DNV
Reliable Detection
Fast response to a wide range of hydrocarbon and hydrogen fires even in low visibility conditions. Advanced diagnostics, including window clarity, maintain site protection.
Easy to Use
Low maintenance and calibration-free. Lightweight, compact, graduated mount enables simple mechanical installation. Two cable inlets and plug-in connections facilitate electrical installation.
Multiple Outputs
Multiple outputs include 4-20mA, Relays, HART®, and Modbus. Easily integrate FS24X Plus into your systems.
Robust
Operates in challenging environments to maintain safety coverage. Advanced solid-state, wide-band sensors enable detection through conditions like rain, fog, and smoke.
At a Glance Instrument Status
High visibility LED HALO ring provides a clear indication of device status. LED HALO: Green (Normal), Yellow (Fault/Warning), Red (Alarm).
Simple Maintenance
Internal diagnostics and warnings drive maintenance. A simple test lamp allows quick and easy testing at a distance, eliminating the need to climb to the instrument. Replaceable electro-optics modules enable convenient field replacement.
Since it can readily detect both hydrocarbon and non-hydrocarbon flames — even in challenging conditions — Honeywell FS24X Plus is an ideal flame detector for numerous applications, including:
- Refineries and oil production plants
- Offshore platforms
- Turbine/compressor enclosures
- Oil and gas pipelines and pumping stations
- Loading and unloading facilities for liquefied petroleum and natural gas
- Natural gas/compressed natural gas plants
- Production and storage facilities for ethanol, methanol and isopropanol
- Tank farms and storage facilities for crude oil and gasoline
- Aircraft hangars
- Paint and solvent storage
- Chemical production, storage and loading facilities
- Power plants
- Wastewater plants
