Protection Height (FF-SYA14, FF-SYA30 and FF-SYA60 series)
The Protection height is the height on which the test rod will be detected.
2.4.4
Beam spacing and number of beams (FF-SYA234 Series)
For FF-SYA234 multibeam systems for access detection, beam spacing indicates the distance between the optical axis of two
consecutive beams. The beam spacing of the FF-SYA multibeam system and the beam heights above the reference plane are
in compliance with the European standards EN 999.

NON COMPLIANCE TO ANSI/RIA 15.06–1999 WITH FF-SYA02500
Only the three beam (FF-SYA03400 Series) and the four beam versions (FF-SYA04300 Series) are in compliance with the
beam heights, specified in the US Standard ANSI/RIA R15.06-1999 (Industrial Robots and Robot Systems – Safety
Requirements). The two beam version (FF-SYA02500 Series) does NOT comply with ANSI/RIA R15.06 and may require
additional protection.
Refer to applicable standards. In the absence of an applicable standard, ANSI B11.19 and ANSI R15.06 may be used as
reference for the USA, as well as EN 999 (or the relevant European Type C machine standard) for Europe.
