Flame 2000

Visually inspect optical window for debris; perform automatic built-in test (BIT) for window contamination; clean with lint-free cloth and isopropyl alcohol if contamination detected; even minor contamination can reduce sensitivity by up to 50% per NFPA 72

Perform sensitivity testing using manufacturer-approved test methods (e.g., Dräger FS-5000 flame simulator for Flame detectors); test within 1 year of installation and every 2 years thereafter; sensors outside rated range must be cleaned, recalibrated, or replaced

Verify unobstructed field of view per specifications; check for dust, condensation, or physical objects blocking detector line of sight; confirm mounting position and alignment; use visual technology (Flame 5000) or bore-sight tools to verify clear optical path

Verify 18-32 VDC power supply and correct polarity; test HART/Modbus communication if equipped; check 4-20 mA signal output (normal ~4 mA, warning ~16 mA, alarm 20 mA); perform monthly functional tests; verify LED indicator status (green=normal, yellow=fault, red=radiation detected)

Confirm detector rated for actual operating environment (-60°C to +85°C range for Flame 5000; ATEX/IECEx for hazardous areas); inspect for corrosion of stainless steel or aluminum housing; in offshore/dusty environments increase cleaning frequency to quarterly or monthly vs. annual minimum
