85UVF4A-1QDWR Fireye Phoenix II Integrated UV Flame Scanner

Overview

The Fireye 85UVF4A-1QDWR Phoenix II is an advanced, microprocessor-based integrated flame scanner designed for precise ultraviolet (UV) flame detection and monitoring. As a self-checking device, it incorporates a solid-state UV sensor and an internal flame relay, eliminating the need for a remote flame amplifier. It is engineered to improve the safety and reliability of combustion systems by providing fast and accurate flame verification in demanding industrial and commercial environments.

Features

• Ultraviolet (UV) sensor for accurate and reliable flame detection.
• Internal flame relay with automatically set ON/OFF thresholds.
• User-selectable Flame Failure Response Time (FFRT) for application flexibility.
• Full self-diagnostics and electronic self-checking for enhanced safety.
• 4-button keypad with multiple LED indicators for flame signal strength, relay status, and fault codes.
• Compact and rugged cast aluminum housing with a gray polyester powder coat.
• Quick-disconnect 8-pin electrical connection for easy installation.
• One optically isolated 4-20mA analog output for flame strength monitoring.
