MSA FL500 UV/IR — hydrocarbon flame detector
The FL500 UV/IR is a compact flame detector that monitors radiation in the ultraviolet and infrared ranges, providing a fast response time and increased resistance to false alarms. FM Performance Approved certification across seven fuels, a 130° field of view and optical self-check every 2 minutes make it a reliable solution for industry.

Key features
- Proven UV/IR technology — two independent sensors monitoring two different flame radiation spectra, increasing resistance to false alarms.
- FM Performance Approved certification — tested on seven fuel sources (heptane, methane, methanol, propane, ethane, butane, hydrogen) with field-of-view verification.
- Wide field of view — 130° cone.
- Continuous Optical Path Monitoring (COPM) every two minutes — confirms optical clarity and electronics functionality.
- Testable anytime, anywhere with the TL105 test lamp — simulating flame flicker under real fire conditions.
- Wide operating temperature range: -55°C to +85°C.
- Three LED indicators signaling warning, alarm and normal operation.
- Rugged 316 stainless-steel housing.

Frequently asked questions (FAQ)
What fuel sources does the FL500 UV/IR detect?
The detector carries FM Performance Approved certification, confirmed by tests on seven fuel sources: heptane, methane, methanol, propane, ethane, butane and hydrogen.
How can the detector be tested without an open flame?
A dedicated TL105 test lamp is used for safe testing, simulating flame flicker under conditions similar to an actual fire.
Does the device signal its own faults?
Yes — the Continuous Optical Path Monitoring (COPM) function checks optical clarity and electronic circuit functionality every two minutes.
