Fits lighter industrial flame detection where you need a Honeywell FSL100 in UV, UV/IR, or IR3 GRP housing with 4–20 mA and relays.
Key advantages
- Sensor choices — UV, UV/IR, or triple IR (IR3) optoelectronic flame detection
- Range class — UV and UV/IR typically 80 ft; IR3 typically 110 ft (n-heptane class per datasheet)
- FOV — Approximately 90° solid angle coverage
- Outputs — 4–20 mA stepped analog plus alarm and fault SPDT relays (30 VDC / 2 A, 60 W max class)
- Housing — Glass-reinforced polyester (GRP); red or white; UL94 V-0; IP65
Typical applications
- General industrial flame detection on skids and enclosures.
- Sites choosing UV, UV/IR, or IR3 within the FSL100 family.
- IP65 GRP installs with stepped 4–20 mA plus alarm/fault relays.
Selection guide
- Sensor type — UV vs UV/IR vs IR3 (range differs).
- Supply — 10–28 VDC (product page ~12–14 VDC / ~25 mA nominal class)
- Color / housing — red or white GRP UL94 V-0.
- Ambient — Minimum −40 °C class; see datasheet for model-specific maxima
Common mistakes
- Ordering UV-only for smoky/IR-heavy fires that need IR3.
- Assuming FS20X/FS24X distances on FSL100 — ranges differ by sensor type.
- Ignoring relay contact ratings (30 VDC / 2 A, 60 W max class).
When to RFQ / what to tell us
- UV / UV-IR / IR3 choice; required distance.
- Housing color; quantity; ship-to; certifications needed.
