11.4 Signal Reduction (FR Models)

The following figures show each sensor model’s typical percentage of allowed signal reduction at all temperatures. Refer to these graphs to estimate what percentage of target area must be visible to the sensor at temperatures below the minimum temperature (95% attenuation).
