9.1.3 False Alarm Stimuli Performance
The FMapproved FL5000 detector is immune to a variety of false alarm sources. Below are representative samples of
detector response in the presence of false stimuli.
As a worst case condition the high sensitivity variation was tested to demonstrate no false alarm result without fuel
n-Heptane (1' x 1'), equivalent to 0.3 x 0.3 meters. This generated the following:
