The Honeywell Analytic’s Flame Detector Test Lamp TL-2055X for applications in hazardous areas activates UV, IR and UV/IR Flame detectors that detect at 185-235 nm UV, near IR, wideband IR and 4.4 μ IR radiation.
For these UV, IR and UV/IR the test range is 30-60 cm (1-2 ft). For Fire Sentry FSX detectors FS24X (IR3), FS18X (IR2) and FS20X (IR/IR/UV) the range is up to 5 m (16 ft). Most IR Flame detectors have an extra alarm criterion through analyzing the flicker frequency of a fire. This is the reason why the test lamp emits pulsing light.
