* NOTE:
1.
Response Times and Field of View data have been derived by testing the Model
FL3112 Flame Detector with a 1 square foot gasoline fire. One cup of unleaded
gasoline on top of a one inch layer of water was ignited for each test. These are
typical values and different results may occur depending on the variation of each
fire.
2.
To meet the directional dependence requirements of EN 54-10 the horizontal
viewing angle must not exceed ±30°.
