Fits compact industrial flame detection where you need a Honeywell FSL100 Series detector—UV, UV/IR or triple-IR (IR3) options with detection about 80 ft (UV/UV-IR) or 110 ft (IR3) on n-heptane class fires, ~90° FOV, 4–20 mA plus SPDT relays, and IP65 GRP housing.
Key advantages
- Sensors — UV, UV/IR, or IR3 options
- Range — About 80 ft UV/UV-IR; 110 ft IR3 (n-heptane class)
- FOV — About 90° solid angle
- Outputs — 4–20 mA stepped + alarm/fault SPDT relays
- Housing — GRP; IP65; M20 entries
Typical applications
- Light industrial fire detection.
- Equipment skids.
- Indoor/outdoor compact FOV coverage.
Selection guide
- UV vs UV/IR vs IR3
- Color / bracket
- Relay mapping
Common mistakes
- Blocked FOV.
- Wrong sensor for fuel.
- Supply outside 10–28 VDC.
