Honeywell FS20X flame detector FS20XUV-IR

**Product Overview**  

The Honeywell FS20XUV-IR is a dual-spectrum flame detector designed for reliable fire detection in high-risk industrial environments. It combines ultraviolet (UV) and infrared (IR) sensing technologies to provide fast and accurate flame recognition while minimizing false alarms from non-fire radiation sources.

**Key Features**  

- **Dual-Spectrum Sensing:** Utilizes simultaneous UV and IR wavelength analysis for enhanced flame discrimination.  

- **High Immunity:** Resistant to common false alarm sources such as welding, lightning, sunlight, and hot objects.  

- **Fast Response Time:** Typically detects hydrocarbon flames within milliseconds.  

- **Rugged Construction:** Housed in a corrosion-resistant, explosion-proof enclosure suitable for harsh conditions.  

- **Field-Programmable:** Configurable sensitivity and alarm settings via onboard controls or remote programming tools.  

- **Self-Check Diagnostics:** Continuous monitoring of sensor health and optical integrity with fault indication.  

- **Multiple Output Options:** Includes relay contacts and 4-20 mA analog output for integration with fire and gas control systems.

**Technical Specifications**  

- **Detection Range:** Up to 60 feet (18 meters) for a 1 ft² (0.1 m²) gasoline pan fire.  

- **Field of View:** 90° conical coverage.  

- **Spectral Bands:** UV (180-260 nm) and IR (4.3-4.4 μm).  

- **Operating Voltage:** 18-32 VDC.  

- **Power Consumption:** Typically 3.5 W in standby, 5 W in alarm.  

- **Operating Temperature:** -40°C to +70°C (-40°F to +158°F).  

- **Enclosure Rating:** IP66/IP67, explosion-proof certifications (e.g., ATEX, IECEx) available.  

- **Outputs:** Two Form-C relays, 4-20 mA signal, Modbus RS-485 communication optional.  

- **Dimensions:** Approximately 150 mm height x 100 mm diameter (excluding mounting bracket).  

- **Weight:** Approximately 1.2 kg.

**Applications**  

- Oil and gas platforms, refineries, and petrochemical plants.  

- Turbine enclosures, generator bays, and power generation facilities.  

- Aircraft hangars, fuel storage areas, and automotive manufacturing.  

- Pharmaceutical and chemical processing facilities.
