Combustion Monitoring Solution – Fireye 45RM4-1001 | 45RM4 Series Scanner
Where This Product Is Used
The Fireye 45RM4-1001 is a self-checking ultraviolet (UV) flame scanner engineered for continuous flame supervision in demanding industrial combustion environments. It is widely deployed in:
- Industrial boilers — oil- and gas-fired package boilers in power generation and process industries
- Burner management systems (BMS) — as the primary flame-detection sensor in NFPA 85 / EN 746-2 compliant safety loops
- Thermal oxidizers & incinerators — ensuring pilot and main flame presence during waste-gas combustion
- Kilns & dryers — cement, lime, and mineral processing where high-temperature ambient conditions demand robust UV detection
- Fired heaters & process furnaces — refinery and petrochemical applications requiring SIL-rated flame supervision
- Marine & offshore boilers — where compact form factor and vibration tolerance are critical

Why Engineers Specify This Model
- Self-checking UV tube — periodic self-test cycle confirms sensor integrity without manual intervention, meeting IEC 61511 functional safety requirements
- High UV sensitivity — detects hydrogen, natural gas, oil, and propane flames reliably even in high-background-radiation environments
- Compact, rugged housing — stainless-steel scanner head withstands vibration, moisture, and elevated ambient temperatures common in boiler rooms
- Drop-in compatibility — direct replacement for legacy Fireye 45RM series scanners; no amplifier rewiring required in most installations
- Proven field record — 45RM4 platform has decades of installed base across global power and process industries
- Simplified commissioning — plug-and-play interface with Fireye EP266, EP270, and 48PT amplifier cards

Application-Specific FAQ
Q: Is the 45RM4-1001 compatible with my existing Fireye EP266 amplifier?
A: Yes. The 45RM4 series is designed to interface directly with Fireye EP266, EP270, and 48PT amplifier cards. No hardware modification is required.
Q: Can this scanner detect oil flame as well as gas flame?
A: Yes. The UV detection method responds to the ultraviolet radiation emitted by both oil and gas combustion, making it suitable for dual-fuel burner applications.
Q: What is the maximum sight pipe length recommended?
A: Fireye recommends a maximum sight pipe length of 24 inches (610 mm) for standard installations. Longer runs may require a purge air system to maintain UV signal strength.
Q: Does this unit require periodic calibration?
A: The self-checking circuit performs automatic functional verification. Annual inspection of the UV tube and optical window cleaning is recommended per Fireye maintenance guidelines.
Q: Can Konmask provide a Certificate of Conformance for this part?
A: Yes. CoC documentation is available upon request for B2B and EPC procurement requirements. Contact support@konmask.com.
