Description
1. At-A-Glance Executive Brief
- Model: 65UV5-1004QD
- Brand: Fireye
- Part Type: Integrated Ultraviolet (UV) Flame Scanner
- Lifecycle Status: Active / Industrial Burner Management Tier
- Supply Voltage: 24 VDC
- Flame Failure Response Time (FFRT): 4 seconds
2. Technical Introduction
Unplanned burner trips triggered by faulty flame scanners can cause catastrophic boiler shutdowns and expensive facility restarts.
The Fireye 65UV5-1004QD operates as a self-contained ultraviolet tube-type flame scanner designed for continuous monitoring of industrial burner flames. It converts optical UV radiation from oil or gas flames into a reliable solid-state relay output signal, interfacing directly with burner management systems (BMS) to ensure rapid fuel shutoff during flame loss events.
- Best Suited For:
- Industrial boiler and utility burner management retrofits
- Process heater and furnace combustion safety systems
- Direct replacement in legacy Fireye integrated scanner mounts

4. Field Engineer’s Tech Notes
- Optical Lens Cleanliness: Inspect the quartz viewing window regularly for soot, oil mist, or moisture accumulation. Even a thin film of contamination will attenuate ultraviolet transmission and cause nuisance low-signal flame trips.
- Electrical Noise and Shielding: Route the 24 VDC supply and signal wiring away from high-voltage ignition transformers and variable frequency drive cables. Induced electrical noise on the scanner leads can corrupt the internal flame relay logic and mimic flame flicker.
5. Adaptive QA & Testing Protocol
Each unit undergoes optical bench testing using regulated UV light sources to verify tube sensitivity, response threshold tracking, and flame failure response timing (FFRT). Technicians test the internal solid-state relay switching cycles, 4-20 mA analog signal output scaling, and supply voltage tolerance limits. Complete functional inspection logs and test videos are available upon request prior to dispatch.
6. Buyer’s FAQ
- What operational condition is this scanner supplied in?
We stock this part in factory-sealed New Surplus (NSFP) and rigorously bench-tested refurbished conditions, backed by a standard operational warranty.
- What is the typical shipping lead time for urgent requirements?
Orders process and dispatch within 1 to 2 business days via global priority couriers to minimize burner downtime during plant outages.
- Is this exact model directly compatible with older Fireye burner controls?
Yes, the 65UV5-1004QD maintains form-factor and pinout compatibility with standard Fireye integrated mounting collars, provided your system supplies the required 24 VDC power.
