The sensitivity range (setting) for the 4098-9714 and 4098-9754 sensor is 0.2%/FT to
3.7%/FT smoke obscuration. The sensitivity range (setting) for 4098-9717 sensors is
0.5%/FT to 1.3%/FT.
0.5%/FT and 0.9%/FT settings for the 4098-9717 sensor are for special applications only.
The 0.2%/FT, 0.5%/FT, 0.9%/FT, and 1.0%/FT settings are very sensitive settings: only use the
0.2%/FT setting when a sensor is located in a totally smoke-free and controlled
temperature environment, such as a computer room or telephone switching exchange.
