Figure 41: Maximum allowable displacement for a range of fume hood widths

The area protected by the light beams should cover the open area under the sash,
typically 500 mm (20") from its base.
The light curtain transmitter and receiver can be positioned above the bottom of the
sash in the fume hood if they are free from obstructions.
Where possible, make sure the light path is aligned flush to the bottom of the sash
base.
Note: There is a 123 mm (4.84") gap from the top of the light curtain transmitter to
the first LED down and a 22 mm (0.87") gap from the bottom of the transmitter
to the first LED up.
