False Stimuli Response Test
All four samples of the Model 20/20 MI-1with sensitivity setting 10, considered
representative of the series, were tested in the presence of modulated and non-
modulated artificial sources of light and other heated bodies, then, in the presence
of each of the false stimuli, were exposed to the standard test consisting of a 12 in.
x 12 in. (0.3m. x 0.3m.) N-heptane pan fire. The false stimuli sources were as
follows:
1. Resistive Electric Heater (1350w) at 3 ft. (1m.)
2. Fluorescent light (40 w) at 3 ft. (1m.)
3. Halogen light (500 w with lens) at 3 ft. (1m.)
4. Incandescent Light (100 w) at 3 ft. (1m.)
5. Arc welding with setting at 200 Amperes at 10 ft. (3 m.) using 7011 rod and
steel plate.
The detectors produced no trouble or false alarm signal in the presence of these
false stimuli at the distance specified, and they continued to respond satisfactorily
to the test fire in the presence of these sources.
