Overview The Fireye 65UV5-1004QD is a self-checking, microprocessor-based ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. This integrated, one-piece system detects UV emissions from fossil fuel flames, such as natural gas, propane, and light oil. By incorporating an internal flame relay with a fixed ON/OFF threshold, it eliminates the need for an external flame amplifier, providing a compact and reliable solution for modern combustion systems. Features Self-Checking Technology: Utilizes an electro-mechanical shutter mechanism to provide continuous self-checking of the UV tube, ensuring high levels of safety and reliability. Integrated Design: Features an internal SPDT flame relay, allowing for direct connection to burner management systems without additional signal processing hardware. Analog Feedback: Provides a 4-20 mA DC analog output proportional to the flame signal strength for remote monitoring and trend analysis. Local Diagnostics: Includes a two-color internal LED (visible through a rear viewing port) that indicates flame status and fault conditions. Durable Construction: Housed in a rugged cast aluminum NEMA 4X / IP66 enclosure, making it suitable for harsh industrial environments and hazardous locations. Ease of Maintenance: Equipped with an 8-pin quick-disconnect connector to simplify field wiring, installation, and replacement. Specifications Model: 65UV5-1004QD Sensor Type: Ultraviolet tube-type Flame Failure Response Time (FFRT): 4 seconds Supply Voltage: 24 VDC ( 10% / -15%) Power Consumption: Approximately 3.8 Watts Relay Output: SPDT flame relay (normally open/normally closed) Analog Output: 4-20 mA DC Housing Rating: NEMA 4X / IP66 (Cast Aluminum) Mounting: 1 inch NPT female threads Temperature Rating: -40 degrees F to 150 degrees F (-40 degrees C to 65 degrees C) Hazardous Area Rating: Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G Weight: Approximately 4 lbs (1.8 kg) Applications The 65UV5-1004QD is used in a variety of industrial and commercial combustion settings, including: Industrial furnaces and steam-generating boilers. Monitoring of gas-fired and light oil-fired burners. Process heaters and incineration equipment. Retrofit applications where older UV flame detectors are being replaced with integrated, self-checking technology. Hazardous location installations requiring Class I or Class II Division 2 compliance.
