The minimum safety distance S allowed from the danger zone to the vertical
detection plane should be no less than that calculated using the following
formula:

This formula applies for all safety distances of S greater than 100mm and
up to and including 500mm. If S is found to be greater than 500mm using
the above-mentioned formula, then the distance may be reduced using the
following formula with a minimum distance of 500mm:
S = 1600(t
S = 1600(tS = 1600(t

When access to the danger zone can be gained over the top or the bottom
of the barrier or laterally, additional safeguarding devices should be
provided to prevent access. They should comply with requirements of both
EN 294 and prEN 811 European norms.

If the direction of approach is parallel to the plane of detection, e.g. if the
barrier is horizontally mounted, the minimum 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(tS = 1600(t
S = 1600(t

) + 1200 – 0.4H
The height H should be a maximum of 1000mm 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 additional safety
measures are required.
