The risk of inadvertent access should be taken into account during the risk
assessment stage, but in all cases, the height H of the uppermost beam
should be greater or equal to 900mm, and the height P of the lowest beam
should be lower or equal to 300mm.

If the direction of approach is parallel to the plane of detection, e.g. if the
barrier is horizontally mounted, the minimun safety distance S from the
danger zone to the outer beam depends on the height H of the curtain above
the ground. This safety distance S should be calculated using the following
formula:
S = 1600(t S = 1600(t S = 1600(t S = 1600(t

) + 1200 – 0.4H ) + 1200 – 0.4H ) + 1200 – 0.4H ) + 1200 – 0.4H
The height H should be a maximum of 1000mm from the ground and the
lowest allowable installation height of the 55mm resolution device is 75mm
from the ground. However, if the installation height H is greater than
300mm there is a risk of inadvertent undetected access beneath the curtain,
and this must be taken into account in the risk assessment.
