Description
Product Overview
The Honeywell 51401497-100 FW25-92 is a high-sensitivity flame detector designed for critical fire and gas detection in hazardous industrial environments. Part of Honeywell’s FW25 series, this device employs multi-spectrum infrared (IR) sensing technology to reliably detect hydrocarbon-based flames while minimizing false alarms from non-fire radiation sources. The Honeywell 51401497-100 FW25-92 is engineered for SIL 2 compliance per IEC 61508/61511, ensuring robust performance in oil refineries, offshore platforms, and chemical processing plants. Its rugged, corrosion-resistant enclosure (IP66/IP67) and wide operating temperature range (-40°C to +75°C) make it suitable for extreme conditions.
Featuring rapid response times (<5 seconds) and a 120-degree field of view, the Honeywell 51401497-100 FW25-92 integrates seamlessly with fire and gas control panels via 4-20 mA analog outputs and HART communication. The detector’s self-diagnostic functions continuously monitor lens cleanliness and sensor health, providing predictive maintenance alerts to reduce downtime. As a cornerstone of Honeywell’s safety instrumented systems (SIS), the Honeywell 51401497-100 FW25-92 plays a vital role in preventing catastrophic asset damage and ensuring personnel safety.

Key Functional Features
The Honeywell 51401497-100 FW25-92 combines advanced optical filtering and signal processing to distinguish between true flames and background interference, such as welding arcs or sunlight. Its triple IR sensor array detects multiple flame signatures, including hydrocarbon, hydrogen, and methanol fires, with 99% accuracy.
Operational advantages:
- Dynamic Sensitivity Adjustment: Automatically adapts to environmental conditions like rain, fog, or dust.
- Built-in Modbus RTU Interface: Enables direct integration with DCS/SCADA systems for centralized monitoring.
- Lens Contamination Detection: Triggers alarms when obscuration exceeds 50%, ensuring uninterrupted protection.
Application Scenarios
The Honeywell 51401497-100 FW25-92 is deployed in high-risk industries requiring fail-safe fire detection. In LNG terminals, it monitors storage tank zones for methane leaks and ignition events. Offshore rigs rely on its ATEX-certified design to detect flare stack malfunctions or hydrocarbon leaks in classified areas.
Chemical manufacturing plants use the Honeywell 51401497-100 FW25-92 to safeguard reactors and distillation columns, while power generation facilities install it near turbine halls for hydrogen fire detection. Its SIL 2 certification also makes it ideal for pharmaceutical cleanrooms, where fire risks from solvent-based processes demand rigorous safety protocols.
