Information About FS20X-211-21-2
The FS20X-211-21-2 is part of Honeywell’s Flame Sentry (FSX) Series, utilizing patented UV/Dual IR/VIS detection technology for rapid response to a wide range of hydrocarbon and non-hydrocarbon fires. This advanced sensor combination enhances detection range while minimizing susceptibility to false triggers from sunlight, welding, or hot surfaces. The detector operates on 18–32 VDC, features a ¾-inch NPT mounting connection, and is designed for Class I and II Division 1 and 2 hazardous locations. With intelligent signal processing and field-proven reliability, the FS20X-211-21-2 is ideal for refineries, aircraft hangars, chemical plants, and power generation facilities requiring high-performance flame monitoring.
Key Features:
- UV/Dual IR/VIS Detection: Multi-spectrum sensing ensures accurate flame recognition and superior false alarm rejection.
- Wide Voltage Range: Operates from 18 to 32 VDC for flexible system integration.
- High Sensitivity: Detects hydrocarbon and non-hydrocarbon fires with extended range.
- Fast Response Time: Rapid flame detection within milliseconds for critical protection.
- Rugged Construction: Suitable for Class I/II, Division 1 and 2 hazardous areas.
- Standard Mounting: ¾-inch NPT connection for simplified field installation.
- Low Power Consumption: Efficient design with typical circuit resistance of 50–400 ohms.
- Proven Reliability: Designed for harsh industrial and outdoor fire protection environments.
The FS20X-211-21-2 delivers the reliability and precision required for high-speed, multi-spectrum flame detection in critical safety applications.
