These operate in tandem with corresponding relays on the I/O board to indicate progressive levels of smoke
and are programmable for obscuration level.
7. Logarithmic smoke density bar graph
Displays 0 to 20 % obs/m (0 - 6.09 %obs/ft) with a resolution of 0.001 % obs/m (0.0003% obs/ft) at the lower
end.
